The surface is the foundation for future history manipulation. A compaction or tool-result-prune plugin appends one of the existing message-producing event types (a `user/message` carrying the summary, say) with `surfaceOp: { op: 'replace', start, end }` and `sourceEventSeqs` covering the shadowed entries — the new event takes the range's place on the surface while the plugin's own trace events (e.g. `compaction/start`, `compaction/end`) stay off it. Replay preserves the decision deterministically.
+
+A `tool/result` replacement may rewrite exactly one current `tool/result` and must preserve every data field except `content`. Session acceptance enforces this rule together with positional range and provenance validation, independent of optional diagnostic plugins.

+# Agent Note: Project canonical documentation into the website
+
+Status: implemented
+
+## Problem
+
+The repository needs a navigable documentation website without turning the website directory into a second documentation source. Copying package guides, architecture pages, or generated catalogs into a site-specific tree allows the two copies to drift, while pointing VitePress directly at the repository root couples public URLs and navigation to the internal file layout. Repository-relative links also need different destinations on the website: published pages stay inside the site, but source files and unpublished contributor documents belong on GitHub.
+
+## Decision
+
+Canonical Markdown remains in the repository tier that owns it. Product-facing guides live under `docs/user/`, generated reference remains in the existing generated catalogs, and architectural and cookbook pages remain at their existing `docs/` paths.
+
+`website/docs.ts` is an explicit publication manifest. Each entry maps one canonical source file to a stable public route, sidebar, section, and order. Adding or removing a published page is therefore a reviewable manifest change rather than an implicit directory crawl.
+
+`scripts/project-doc-site.ts` projects the manifest into the ignored `website/.generated/` directory before VitePress starts or builds. The generated tree follows public routes so VitePress navigation, locale detection, and local search share the same route vocabulary. Each page receives an `editSource` frontmatter field pointing to its canonical repository file; the edit-link callback reads only that page data, so public URLs remain independent of the source layout.
+
+Locale home projections retain only the canonical YAML frontmatter. The repository-facing body can keep its H1 and bilingual source links, while the VitePress home theme owns the rendered hero and features and the site navigation owns locale switching.
+
+The projector parses Markdown links without reserializing the document. A link to another published source becomes a site-relative route; a link to an unpublished repository file becomes a GitHub source link; a repository image becomes a raw GitHub URL. Missing relative targets fail projection. Unit tests pin these transformations, and `docs:check` runs the projector tests plus a production VitePress build as part of `doc-sync` and the parallel documentation gates.
+
+Mermaid renders the canonical diagrams. The website workspace explicitly declares the five packages that `vitepress-plugin-mermaid` asks Vite to prebundle because pnpm's strict dependency isolation otherwise makes those transitive packages unavailable to the local development server; Knip records this runtime-only use as an intentional dependency exception.
+
+Site publication is separate from site construction. The repository contains local development and build commands, but no hosting or deployment workflow until a public destination is chosen.
+
+## Alternatives considered
+
+**Commit copied Markdown under `website/`.** This makes VitePress setup direct, but every copied guide or API table gains two owners and requires a synchronization convention that cannot identify which copy is authoritative.
+
+**Make `website/` the canonical home for every published page.** This keeps one copy but moves architecture, generated reference, and contributor-facing material away from their repository ownership tiers merely to satisfy a renderer.
+
+**Discover every Markdown file automatically.** This minimizes manifest maintenance but publishes internal documents accidentally, exposes source moves as URL changes, and produces navigation from incidental directory order.
+
+**Use filesystem symlinks.** Symlinks preserve a single source but do not solve public routing or repository-relative links, and their behavior is less predictable across local development, package tooling, and hosted CI environments.
+
+**Build only in a deployment workflow.** A deployment job can reveal rendering failures after merge. Keeping the production build in `doc-sync` makes the same failure visible locally and in ordinary CI even when no public deployment exists.
+
+## Consequences
+
+Documentation facts have one editable home, public routes remain stable across source moves, and the site can include generated references without committing another generated copy. Local development watches canonical inputs and regenerates the disposable projection.
+
+The publication manifest is a maintained allowlist, and link projection adds a small repository-specific build adapter. A new kind of Markdown link behavior needs a projector test. Mermaid support also increases the client bundle size, but preserves diagrams already used by the canonical documentation.

+# Agent Note: Generate the Cordis core API reference
+
+Status: implemented
+
+English | [中文](2026-07-20-generated-cordis-core-api.zh.md)
+
+## Problem
+
+Plugin authors need the detailed Cordis APIs behind `ctx`, event dispatch, fibers, plugin registration, and services. The generated [Harness event and service catalogs](2026-06-20-generated-cordis-catalog.md) intentionally summarize inherited Cordis members, so they do not replace a method-level Cordis reference. Keeping a second hand-written copy under the website would drift from the vendored source and make the renderer an additional documentation owner.
+
+## Decision
+
+`scripts/cordis-core-api.ts` reads the public declarations and original JSDoc from `vendor/cordis/src` with the TypeScript compiler API. An explicit page manifest generates five files under [`docs/cordis-catalog/core/`](../../../../docs/cordis-catalog/core/context.md): Context, Events, Fiber, Registry, and Service. `scripts/gen-cordis-catalog.ts` writes these pages together with the Harness event and service catalogs, and `verify-cordis-catalog` rejects stale output.
+
+The generator validates that documented classes and methods retain descriptive JSDoc, including parameter and non-void return contracts. It emits declaration-only `ts cordis-catalog` fences with the original JSDoc, then renders the same description, parameters, and return contract as readable Markdown. Source links point to the vendored files, and the five pages cross-link to one another. The Harness catalogs remain the exhaustive inventory of repository-declared events and `ctx.*` services; the core pages document how the inherited Cordis APIs operate.
+
+`website/docs.ts` publishes the five canonical files under matching `/reference/cordis-api/` and `/en/reference/cordis-api/` routes. Both locales use the English generated source until the generator emits translated pages, so changing language preserves navigation structure and route identity.
+
+## Alternatives considered
+
+**Restore the old website files as canonical Markdown.** This would recover the pages quickly, but their signatures and prose could drift from the vendored implementation and the website would regain a second documentation source.
+
+**Expand the inherited tier of the Harness catalogs in place.** Those catalogs answer which Harness events and services exist. Mixing full framework class references into the same pages would obscure that inventory and reverse their deliberate terse inherited tier.
+
+**Publish vendored source declarations directly.** Source files are authoritative but do not provide stable topic pages, curated public ordering, or website navigation, and they expose implementation bodies that are not part of the reference contract.
+
+## Consequences
+
+The five Cordis API pages follow vendor updates through one deterministic generator and share the repository's documentation freshness gate. The website gains a dedicated Cordis API section without copied site content, while root and English navigation remain structurally identical.
+
+The page manifest is curated, so a newly public Cordis core type needs an explicit generator entry. Generated prose is English-only, and source JSDoc quality directly limits reference quality; Chinese output requires generator-level translation rather than hand-editing the generated files.

+# Agent Note: 生成 Cordis 核心 API 参考文档
+
+Status: implemented
+
+[English](2026-07-20-generated-cordis-core-api.md) | 中文
+
+## 问题
+
+插件作者需要了解 `ctx`、事件派发、Fiber、插件注册和 Service 背后的详细 Cordis API。已有的 [Harness 事件与服务目录](2026-06-20-generated-cordis-catalog.md)有意只简要概括继承自 Cordis 的成员，因此无法替代方法级 Cordis 参考文档。如果在网站下维护另一份手写副本，它会与 vendored 源码产生漂移，也会让渲染器成为额外的文档所有者。
+
+## 决策
+
+`scripts/cordis-core-api.ts` 使用 TypeScript Compiler API，从 `vendor/cordis/src` 读取公开声明和原始 JSDoc。一个显式页面清单在 [`docs/cordis-catalog/core/`](../../../../docs/cordis-catalog/core/context.md) 下生成五个文件：Context、Events、Fiber、Registry 和 Service。`scripts/gen-cordis-catalog.ts` 将这些页面与 Harness 事件和服务目录一同写入，`verify-cordis-catalog` 会拒绝过期产物。
+
+生成器会验证所记录的类和方法保留描述性 JSDoc，包括参数和非 void 返回值契约。它生成包含原始 JSDoc 且仅含声明的 `ts cordis-catalog` 代码围栏，再将同一份说明、参数和返回值契约渲染为便于阅读的 Markdown。源码链接指向 vendored 文件，五个页面之间相互交叉链接。Harness 目录仍是仓库声明的事件与 `ctx.*` 服务的完整清单；核心页面负责说明继承自 Cordis 的 API 如何工作。
+
+`website/docs.ts` 将五个规范源文件发布到结构对应的 `/reference/cordis-api/` 和 `/en/reference/cordis-api/` 路由。在生成器产出翻译页面之前，两个 locale 都使用英文生成源，因此切换语言时导航结构和路由标识保持不变。
+
+## 考虑过的替代方案
+
+**将旧网站文件恢复为规范 Markdown。** 这能快速恢复页面，但其签名和说明可能与 vendored 实现漂移，网站也会重新成为第二个文档来源。
+
+**直接扩充 Harness 目录中的继承层。** 这些目录回答有哪些 Harness 事件与服务。将完整的框架类参考混入同一页面会模糊这份清单的定位，并推翻继承层保持精简的既有决定。
+
+**直接发布 vendored 源码声明。** 源文件具有权威性，但不能提供稳定的主题页面、经过筛选的公开顺序或网站导航，还会暴露不属于参考契约的实现体。
+
+## 影响
+
+五个 Cordis API 页面通过同一个确定性生成器跟随 vendor 更新，并复用仓库的文档新鲜度检查。网站无需复制内容即可获得独立的 Cordis API 章节，中文入口和英文入口的导航结构保持一致。
+
+页面清单需要人工维护，因此新增公开 Cordis 核心类型时必须显式添加生成器条目。当前生成说明只有英文，且源码 JSDoc 的质量直接决定参考文档质量；中文产物需要在生成器层实现翻译，不能手工编辑生成文件。

+description: Use when publishing, updating, moving, or removing DeepSeek Harness documentation website pages; editing website/docs.ts mappings or navigation; diagnosing a page missing from the VitePress site; fixing projected documentation links; or running the docs:dev, docs:check, and doc-sync workflow after website-content changes.
+---
+
+# Synchronizing the DeepSeek Harness Documentation Site
+
+Keep repository Markdown as the only editable content source. Treat the website as a tested projection: [website/docs.ts](../../../website/docs.ts) selects public pages, [scripts/project-doc-site.ts](../../../scripts/project-doc-site.ts) rewrites them into the disposable `website/.generated/` tree, and VitePress builds that tree.
+
+Repository translations follow the sibling pairing contract: English `foo.md`, Chinese `foo.zh.md`, and `foo.i18n.yaml` live together. Never create `zh-CN/` or other locale directories for website content. The site route trees are independent of that source layout: `foo.zh.md` projects to the root route and `foo.md` projects to the matching `/en/` route.
+
+## Read the owning contracts
+
+- Read [docs/AGENTS.md](../../../docs/AGENTS.md) and use [dsh-doc-standards](../dsh-doc-standards/SKILL.md) when deciding where content belongs or changing product documentation prose.
+- Use [dsh-translate-docs](../dsh-translate-docs/SKILL.md) whenever an edited source has a bilingual counterpart.
+- Read the current `DocsPage` type and entries in [website/docs.ts](../../../website/docs.ts) before changing the manifest; do not rely on a remembered field set.
+- Read [website/.vitepress/config.ts](../../../website/.vitepress/config.ts) before adding a new section, sidebar collection, locale, or top-level navigation item.
+
+## Classify the change
+
+- **Edit an already published page:** change only its canonical Markdown source. Do not touch the manifest unless its route or navigation metadata changes.
+- **Publish a new page:** create it in its owning `docs/` tier, then add one manifest entry.
+- **Rename, move, or remove a page:** update the canonical file, manifest entry, and inbound repository links atomically. Remove stale manifest entries; `docs:check` rejects missing sources.
+- **Publish a generated catalog:** map the generated `docs/` file, but change its generator or source metadata rather than editing the catalog by hand.
+- **Change site structure:** update the manifest for ordinary pages; update VitePress configuration only when the existing sidebar, section, or locale model cannot express the change.
+
+Never edit or commit `website/.generated/`, `website/.cache/`, or `website/.dist/`. Never copy a maintained `docs/` page into `website/`.
+
+## Add or update a manifest entry
+
+Set every `DocsPage` field deliberately:
+
+- `source`: repository-relative canonical Markdown path. For a complete bilingual pair, add the English `.md` path through `pairedPages()`; it derives the sibling `.zh.md`, the content locales, and counterpart aliases.
+- `route`: public VitePress path including the `.md` suffix.
+- `label`: sidebar label, not necessarily the document H1.
+- `sidebar`: reuse `zh-guide`, `zh-develop`, or `en-docs` unless the information architecture genuinely needs another collection.
+- `section`: reuse an existing section when possible. If adding one, also place it in `sectionOrder` in the VitePress config.
+- `order`: stable order within the section.
+- `sourceAliases`: optional additional repository paths that should resolve to this page when links are projected. It does not create another public route.
+
+Use `mirroredPages()` only for a source that intentionally falls back to the same available language in both route trees. Convert that entry to `pairedPages()` when its counterpart is added. Keep the manifest an explicit public allowlist. Do not publish RFCs, postmortems, testing guides, `AGENTS.md`, or maintainer workflows merely because they exist under `docs/`; add internal material only when the user explicitly changes the publication boundary.
+
+## Preserve link behavior
+
+Write normal repository-relative Markdown links in canonical docs. The projector applies these rules:
+
+- A target present in the manifest becomes a site-relative route.
+- An existing target outside the manifest becomes a GitHub source link, including supported line suffixes.
+- External URLs, site-absolute URLs, email links, and fragment-only links remain unchanged.
+- A missing repository-relative target fails projection instead of silently producing a broken link.
+
+Do not write website-specific routes into canonical Markdown just to satisfy VitePress. Use `sourceAliases` for directory-style repository links that should resolve to a mapped index page.
+
+## Preview and validate
+
+Run local preview while editing:
+
+```sh
+pnpm docs:dev
+```
+
+The dev server watches mapped source files and reprojects them. Restart it after changing the manifest if the new source is not picked up automatically.
+
+Run the focused website gate before treating the mapping as valid:
+
+```sh
+pnpm docs:check
+```
+
+Before committing a documentation-site change, run:
+
+```sh
+pnpm run doc-sync
+pnpm run lint
+git diff --check
+```
+
+Use [dsh-pre-push-checks](../dsh-pre-push-checks/SKILL.md) before pushing. Report the canonical files changed, manifest entries added or removed, public routes affected, and the exact checks run.
+
+## Keep deployment separate
+
+Synchronizing content into the VitePress build does not publish it to the internet. Do not add GitHub Pages permissions, deployment workflows, custom domains, or public hosting unless the user explicitly requests deployment and confirms the hosting policy.

`CompactService` exposes `compactIfNeeded(agent, trigger, signal)` for automatic `pressure` or `context-overflow` policy, returning `null` when no safe work exists, and `compactRegion(...)` for an explicit inclusive surface range. Implementations must forward the supplied signal to summarization. The seam owns no pricing API: the singleton [`ctx.tokenMeter`](token-meter.md) directly owns estimation and replay, while `dsh-compact-basic` owns retention, event sequencing, routed summarization calls, and their configuration.

+Pressure compaction runs at serial `agent/post-step`, after successful assistant output, tool results, buffered context, and steering are durable but before `step/end`. Once pressure or canonical overflow qualifies, compact-basic invokes optional [`ctx.toolResultPrune`](../../packages/compact/compact-tool-result-prune/README.md) before range selection, remeasures through `ctx.tokenMeter`, and can advance the surface without a summary. Failed-request recovery runs through `agent/request-error` after the failed step closes and authorizes a fresh numbered-step retry only when the surface replacement generation advances, even if later summary work throws after pruning; cancellation still wins. Region boundaries preserve tool-call/result pairing but not whole turns, allowing early closed steps of one oversized turn to compact. `dsh-compact-basic` owns thresholds, retained-tail policy, overflow caps, and failure handling.
The seam exports `toolPairingBalancedBefore(session, seq)` and `toolPairingBalancedAfter(session, seq)` for those edge checks. Both validate current surface membership and reject missing seqs and orphan results; the [package contract](../../packages/compact/compact/README.md#tool-pairing-boundaries) owns their cache semantics.

+# Plugin configuration
+
+English | [中文](config.zh.md)
+
+Accept configuration supplied through `cordis.yml`.
+
+## Define the Config type
+
+Export a `Config` type and a same-named Schemastery schema. Put defaults directly on the schema fields:
+
+```ts
+import type { Context } from 'cordis'
+import Schema from 'schemastery'
+
+export const name = 'my-plugin'
+
+export interface Config {
+ greeting: string
+ maxRetries: number
+ verbose?: boolean
+}
+
+export const Config: Schema = Schema.object({
+ greeting: Schema.string().default('Hello'),
+ maxRetries: Schema.number().default(3),
+ verbose: Schema.boolean().default(false),
+})
+
+export function apply(ctx: Context, config: Config) {
+ console.log(config.greeting) // User value or schema default.
+}
+```
+
+Configure it in `cordis.yml`:
+
+```yaml
+- name: './src/my-plugin.ts'
+ config:
+ greeting: 'Hi there'
+ maxRetries: 5
+```
+
+When loading the plugin, Cordis uses the exported schema to validate configuration and fill defaults. Do not export a plain object as `Config`; it does not implement the Standard Schema interface required by Cordis.
+
+## Schema validation
+
+Use Schemastery to express stricter validation:
+
+```ts
+import type { Context } from 'cordis'
+import Schema from 'schemastery'
+
+export const name = 'validated-plugin'
+
+export interface Config {
+ apiKey: string
+ timeout: number
+ mode: 'fast' | 'accurate'
+}
+
+export const Config = Schema.object({
+ apiKey: Schema.string().required(),
+ timeout: Schema.number().default(30000),
+ mode: Schema.union(['fast', 'accurate']).default('fast'),
+})
+
+export function apply(ctx: Context, config: Config) {
+ // config is validated and type-safe.
+}
+```
+
+The schema runs while the plugin loads. Invalid configuration fails the load with an actionable error.
+
+## Design principles
+
+### Do not hardcode tunable values
+
+Harness requires **anything that two deployments may want to set differently to be a configuration field**.
+
+```ts
+// Wrong: hardcoded timeout.
+const TIMEOUT = 30000
+
+// Correct: configurable.
+export interface Config {
+ timeoutMs: number // Defaults to 30000.
+}
+```
+
+The test is whether `cordis.yml` can change the value without a code edit.
+
+### Fail loudly on invalid configuration
+
+If configuration refers to an unregistered LLM provider route or another nonexistent resource, fail early instead of silently skipping it:
+
+```ts
+import type { Context } from 'cordis'
+import type {} from '@deepseek-ai/dsh-llm'
+
+export interface ModelConfig {
+ provider: string
+}
+
+export function apply(ctx: Context, config: ModelConfig) {
+ if (!ctx.llm.listProviders().some(provider => provider.id === config.provider)) {
+ throw new Error(`LLM provider "${config.provider}" is not registered`)
+ }
+}
+```
+
+## Work with HMR
+
+A configuration edit hot-replaces the plugin: the framework unloads the old instance and loads a new one. Because registrations are effects and clean themselves up, replacement does not retain the old instance's registrations.
+

+# Your first plugin
+
+English | [中文](index.zh.md)
+
+This guide creates a minimal Harness plugin and loads it into an agent.
+
+## What is a plugin?
+
+In Harness, a plugin is a TypeScript module that exports an `apply` function. The framework calls `apply` when loading the plugin and passes a `ctx` context object through which the plugin registers capabilities:
+
+```ts
+import type { Context } from 'cordis'
+
+export const name = 'my-plugin'
+
+export function apply(ctx: Context) {
+ // Register capabilities here.
+}
+```
+
+That is the complete shape.
+
+## Create the plugin file
+
+Create `src/my-plugin.ts` in your project:
+
+```ts
+import type { Context } from 'cordis'
+
+export const name = 'hello-plugin'
+
+export function apply(ctx: Context) {
+ // Required dependencies are ready before apply runs.
+ console.log('[hello-plugin] plugin loaded!')
+}
+```
+
+## Register it in cordis.yml
+
+Add an entry to `cordis.yml`:
+
+```yaml
+- id: hello
+ name: './src/my-plugin.ts'
+```
+
+After startup, the console prints `[hello-plugin] plugin loaded!`.
+
+## Automatic cleanup
+
+Anything registered through `ctx`—event listeners, tools, or timers—is cleaned up when the plugin unloads. You do not need to call removeListener or clearInterval manually.
+
+For a resource that needs explicit cleanup, such as a network connection, use `ctx.effect()` to provide its disposer:
+
+```ts
+import type { Context } from 'cordis'
+
+export function apply(ctx: Context) {
+ ctx.effect(() => {
+ const timer = setInterval(() => {
+ console.log('heartbeat')
+ }, 5000)
+
+ // The returned function runs when the plugin unloads.
+ return () => clearInterval(timer)
+ })
+}
+```
+
+## Declare dependencies
+
+If the plugin consumes another service such as `tools` or `llm`, declare it in `inject`:
+
+```ts ignore-check
+import type { Context } from 'cordis'
+
+export const name = 'my-tool-plugin'
+export const inject = ['tools']
+
+export function apply(ctx: Context) {
+ // ctx.tools is ready here.
+ ctx.tools.register(/* ... */)
+}
+```
+
+The framework waits for every required service before loading the plugin.
+
+## Three plugin forms
+
+In addition to a function module, a plugin can use object or class form.
+
+### Object form
+
+```ts
+import type { Context } from 'cordis'
+
+export default {
+ name: 'my-plugin',
+ inject: ['tools'],
+ apply(ctx: Context) {
+ // ...
+ },
+}
+```
+
+### Class form
+
+```ts
+import { Service, type Context } from 'cordis'
+
+export default class MyService extends Service {
+ static inject = ['tools']
+
+ constructor(ctx: Context) {
+ super(ctx, 'myService')
+ // Perform synchronous initialization in the constructor.
+ }
+}
+```
+
+Function form is sufficient in most cases. Use class form when the plugin provides a service to other plugins; see [services and dependencies](../framework/service.md).
+
+## Complete example
+
+`examples/echo-agent/src/echo-tool.ts` is a plugin that registers a tool:
+
+```ts
+import type { Context } from 'cordis'
+import { defineTool } from '@deepseek-ai/dsh-tools'
+
+export const name = 'echo-tool'
+export const inject = ['tools']
+
+export function apply(ctx: Context) {
+ ctx.tools.register(defineTool({
+ name: 'echo',
+ description: 'Echo the given text back, uppercased.',
+ parameters: {
+ text: { type: 'string', required: true },
+ },
+ async execute(args) {
+ return [{ type: 'text', text: `ECHO: ${args.text.toUpperCase()}` }]
+ },
+ }))
+}
+```

+# Build a tool
+
+English | [中文](tool.zh.md)
+
+A tool is a capability the model can call. This guide builds one with `defineTool`.
+
+## Minimal example
+
+```ts
+import type { Context } from 'cordis'
+import { defineTool } from '@deepseek-ai/dsh-tools'
+
+export const name = 'my-tool'
+export const inject = ['tools']
+
+export function apply(ctx: Context) {
+ ctx.tools.register(defineTool({
+ name: 'greet',
+ description: 'Greet someone by name.',
+ parameters: {
+ name: { type: 'string', required: true, description: 'The name to greet' },
+ },
+ async execute(args) {
+ // args is inferred as { name: string }.
+ return [{ type: 'text', text: `Hello, ${args.name}!` }]
+ },
+ }))
+}
+```
+
+## Parameter definitions
+
+`parameters` uses a compact format that the framework converts to the JSON Schema sent to the model.
+
+### Primitive types
+
+```ts
+export const parameters = {
+ path: { type: 'string', required: true },
+ limit: { type: 'number' },
+ recursive: { type: 'boolean' },
+}
+// Inferred type: { path: string; limit?: number; recursive?: boolean }
+```
+
+### Enums
+
+```ts
+export const parameters = {
+ mode: { type: 'string', required: true, enum: ['read', 'write', 'append'] },
+}
+// Inferred type: { mode: string } (enum values are validated at runtime)
+```
+
+### Nested objects
+
+```ts
+export const parameters = {
+ options: {
+ type: 'object',
+ properties: {
+ timeout: { type: 'number' },
+ retries: { type: 'number' },
+ },
+ },
+}
+// Inferred type: { options?: { timeout?: number; retries?: number } }
+```
+
+### Arrays
+
+```ts
+export const parameters = {
+ tags: {
+ type: 'array',
+ items: { type: 'string' },
+ },
+}
+// Inferred type: { tags?: string[] }
+```
+
+### Property fields
+
+| Field | Type | Meaning |
+|------|------|------|
+| `type` | `'string' \| 'number' \| 'boolean' \| 'object' \| 'array'` | Value type |
+| `required` | `true` | Marks the property required and affects inference |
+| `description` | `string` | Description sent to the model |
+| `enum` | `string[]` | Allowed string values |
+| `properties` | `SchemaSpec` | Nested properties for an object |
+| `items` | `SchemaProp` | Element schema for an array |
+
+## The execute function
+
+`execute` receives validated, inferred `args` and an `exec` execution context:
+
+```ts
+import { defineTool } from '@deepseek-ai/dsh-tools'
+
+export const tool = defineTool({
+ name: 'example',
+ description: 'Return an example result.',
+ parameters: {},
+ async execute(args, exec) {
+ // args: inferred from parameters
+ // exec: ToolExecution context
+
+ // Return a ContentBlock array.
+ void args
+ void exec
+ return [{ type: 'text', text: 'result here' }]
+ },
+})
+```
+
+### Return value
+
+`execute` returns a `ContentBlock[]` that becomes the tool result visible to the model:
+
+```ts ignore-check
+// Text result
+return [{ type: 'text', text: 'file content here...' }]
+
+// Multiple blocks
+return [
+ { type: 'text', text: 'Found 3 matches:' },
+ { type: 'text', text: matchResults.join('\n') },
+]
+```
+
+### Argument validation
+
+Before calling `execute`, `defineTool` validates model-generated arguments. Invalid input raises `ToolArgsError`; the framework turns it into an `isError` result so the model can correct its call.
+
+Do not repeat type validation inside `execute`.
+
+## Presentation
+
+A tool can define UI presentation methods for terminal and ACP clients:
+
+```ts ignore-check
+defineTool({
+ name: 'bash',
+ // ...
+ presentCall(args) {
+ return {
+ card: 'terminal',
+ title: args.command,
+ }
+ },
+ presentResult(args, result) {
+ return {
+ card: 'terminal',
+ output: result.content.map(b => b.type === 'text' ? b.text : '').join(''),
+ }
+ },
+})
+```
+
+`presentCall` and `presentResult` are **pure functions**. Streaming UI and session replay may call them more than once.
+
+## Registration and unloading
+
+`ctx.tools.register()` returns a disposer, but a registration made through `ctx` is already tracked by the framework. Unloading the plugin removes the tool automatically, so the plugin does not call the disposer itself.
+
+```ts ignore-check
+// This is sufficient:
+ctx.tools.register(defineTool({ /* ... */ }))
+
+// No saved disposer or extra cleanup registration is needed.
+```
+
+## Complete example
+
+This tool counts files in a directory:
+
+```ts

+# Event system
+
+English | [中文](events.zh.md)
+
+Events are the core communication mechanism between Cordis plugins. Harness uses them extensively for loosely coupled extension points.
+
+## Basic use
+
+### Listen for an event
+
+```ts ignore-check
+ctx.on('event-name', (payload) => {
+ // Handle the event.
+})
+```
+
+### Emit an event
+
+```ts ignore-check
+ctx.emit('event-name', payload)
+```
+
+## Event modes
+
+Cordis provides several event modes for different interaction contracts.
+
+### emit — broadcast
+
+Every listener runs synchronously and return values are ignored:
+
+```ts ignore-check
+// Emit
+ctx.emit('my-plugin/ready', { id: 'worker-1' })
+
+// Listen
+ctx.on('my-plugin/ready', ({ id }) => {
+ console.log(`${id} is ready`)
+})
+```
+
+### bail — short circuit
+
+Listeners run in order; the first non-`undefined` result becomes the final result:
+
+```ts ignore-check
+// Dispatch
+const result = ctx.bail('some-check', input)
+
+// Listen: a returned value stops later listeners.
+ctx.on('some-check', (input) => {
+ if (shouldBlock(input)) return 'blocked'
+ // Return undefined to continue to the next listener.
+})
+```
+
+### serial — ordered execution
+
+Listeners run in registration order and asynchronous results are awaited. The first listener to return a non-empty value stops further execution:
+
+```ts ignore-check
+await ctx.serial('setup-phase', context)
+```
+
+### waterfall — pipeline
+
+Each listener may wrap the downstream result to form a processing chain. A listener **must call `next()` to delegate downstream**; omitting the call vetoes the pipeline:
+
+```ts ignore-check
+// Dispatch
+const output = await ctx.waterfall('my-plugin/transform', input, async () => input)
+
+// Listen: next() is mandatory.
+ctx.on('my-plugin/transform', async (_input, next) => {
+ const downstream = await next()
+ return downstream.trim()
+})
+```
+
+::: warning
+A waterfall listener **must call `next()`**. Omitting it vetoes the pipeline by design, enabling interception and gateway behavior.
+:::
+
+## Typed events
+
+Harness uses TypeScript declaration merging for type-safe events:
+
+```ts
+import 'cordis'
+
+declare module 'cordis' {
+ interface Events {
+ 'my-plugin/ready': (payload: { id: string }) => void
+ 'my-plugin/check': (input: string) => boolean | undefined
+ 'my-plugin/transform': (input: string, next: () => Promise) => Promise
+ }
+}
+
+// ctx.on('my-plugin/ready', ...) and ctx.emit('my-plugin/ready', ...)
+// are now inferred correctly.
+```
+
+## Cordis events and session records
+
+Harness Cordis events use `namespace/action` names, including `agent/pre-step`, `agent/request`, `agent/step-result`, `tools/result`, and `session/event`. The generated [event catalog](../../../cordis-catalog/events.md) records complete signatures and modes.
+
+`turn/*`, `step/*`, `tool/call`, `tool/result`, and `compact/*` are durable session-event types, not same-named Cordis events. To observe them, listen to `session/event` and inspect `event.type`.
+
+## Event listeners are effects
+
+A listener registered with `ctx.on()` is removed automatically when its plugin unloads:
+
+```ts ignore-check
+export function apply(ctx: Context) {
+ // This listener is removed when the plugin disposes.
+ ctx.on('tools/result', handler)
+}
+```
+
+## Example: logging plugin
+
+This plugin logs tool calls and results:
+
+```ts
+import type { Context } from 'cordis'
+import '@deepseek-ai/dsh-tools'
+
+export const name = 'tool-logger'
+
+export function apply(ctx: Context) {
+ ctx.on('tools/result', (exec, result) => {
+ console.log(`[tool] ${exec.name}(${JSON.stringify(exec.arguments)})`)
+ const text = result.content
+ .map(block => block.type === 'text' ? block.text : '')
+ .join('')
+ console.log(`[tool result] ${text.slice(0, 100)}`)
+ })
+}
+```

+# 事件系统
+
+[English](events.md) | 中文
+
+事件是 Cordis 插件间通信的核心机制。Harness 大量使用事件来实现松耦合的扩展点。
+
+## 基本用法
+
+### 监听事件
+
+```ts ignore-check
+ctx.on('event-name', (payload) => {
+ // Handle the event.
+})
+```
+
+### 触发事件
+
+```ts ignore-check
+ctx.emit('event-name', payload)
+```
+
+## 事件模式
+
+Cordis 提供多种事件触发模式，适用于不同场景：
+
+### emit — 广播
+
+所有监听器同步执行，不关心返回值：
+
+```ts ignore-check
+// Emit
+ctx.emit('my-plugin/ready', { id: 'worker-1' })
+
+// Listen
+ctx.on('my-plugin/ready', ({ id }) => {
+ console.log(`${id} is ready`)
+})
+```
+
+### bail — 短路
+
+依次调用监听器，第一个返回非 `undefined` 值的结果作为最终值：
+
+```ts ignore-check
+// Dispatch
+const result = ctx.bail('some-check', input)
+
+// Listen: a returned value stops later listeners.
+ctx.on('some-check', (input) => {
+ if (shouldBlock(input)) return 'blocked'
+ // Return undefined to continue to the next listener.
+})
+```
+
+### serial — 顺序执行
+
+监听器按注册顺序依次执行，并等待异步结果；第一个返回非空值的监听器会终止后续执行：
+
+```ts ignore-check
+await ctx.serial('setup-phase', context)
+```
+
+### waterfall — 管道
+
+每个监听器可以包装下游返回值，形成处理链。**必须调用 `next()` 传递给下游**，不调用即为否决：
+
+```ts ignore-check
+// Dispatch
+const output = await ctx.waterfall('my-plugin/transform', input, async () => input)
+
+// Listen: next() is mandatory.
+ctx.on('my-plugin/transform', async (_input, next) => {
+ const downstream = await next()
+ return downstream.trim()
+})
+```
+
+::: warning
+Waterfall 监听器**必须调用 `next()`**。不调用 `next` 等于否决整个管道，这是故意为之的设计——用于实现拦截/网关逻辑。
+:::
+
+## Typed Events
+
+Harness 使用 TypeScript 声明合并来为事件提供类型安全：
+
+```ts
+import 'cordis'
+
+declare module 'cordis' {
+ interface Events {
+ 'my-plugin/ready': (payload: { id: string }) => void
+ 'my-plugin/check': (input: string) => boolean | undefined
+ 'my-plugin/transform': (input: string, next: () => Promise) => Promise
+ }
+}
+
+// ctx.on('my-plugin/ready', ...) and ctx.emit('my-plugin/ready', ...)
+// are now inferred correctly.
+```
+
+## Cordis 事件与会话记录
+
+Harness 的 Cordis 事件遵循 `namespace/action` 命名，例如 `agent/pre-step`、`agent/request`、`agent/step-result`、`tools/result` 和 `session/event`。完整签名与触发模式见[Events 目录](../../../cordis-catalog/events.md)。
+
+`turn/*`、`step/*`、`tool/call`、`tool/result` 和 `compact/*` 是持久化的会话事件类型，不是同名 Cordis 事件。需要观察它们时，监听 `session/event` 并检查 `event.type`。
+
+## 事件也是效果
+
+通过 `ctx.on()` 注册的监听器会在插件卸载时自动移除：
+
+```ts ignore-check
+export function apply(ctx: Context) {
+ // This listener is removed when the plugin disposes.
+ ctx.on('tools/result', handler)
+}
+```
+
+## 实战示例：日志插件
+
+一个记录所有 tool 调用的简单插件：
+
+```ts
+import type { Context } from 'cordis'
+import '@deepseek-ai/dsh-tools'
+
+export const name = 'tool-logger'
+
+export function apply(ctx: Context) {
+ ctx.on('tools/result', (exec, result) => {
+ console.log(`[tool] ${exec.name}(${JSON.stringify(exec.arguments)})`)
+ const text = result.content
+ .map(block => block.type === 'text' ? block.text : '')
+ .join('')
+ console.log(`[tool result] ${text.slice(0, 100)}`)
+ })
+}
+```

+# Plugins and lifecycle
+
+English | [中文](index.zh.md)
+
+This page describes the Cordis plugin model and lifecycle state machine.
+
+## Fiber state machine
+
+Every loaded plugin owns a **Fiber** scope with the following states:
+
+```
+PENDING → LOADING → ACTIVE
+ ↘ FAILED
+ACTIVE → UNLOADING → DISPOSED
+```
+
+| State | Meaning |
+|------|------|
+| PENDING | Declared, but required dependencies are not ready |
+| LOADING | Dependencies are ready and `apply` is running |
+| ACTIVE | The plugin is running |
+| FAILED | `apply` threw an error |
+| UNLOADING | The plugin is unloading and disposing resources |
+| DISPOSED | The plugin is fully unloaded |
+
+## Dependency-driven loading
+
+A plugin with `inject` waits for every required service before loading:
+
+```ts ignore-check
+export const inject = ['tools', 'llm']
+
+export function apply(ctx: Context) {
+ // ctx.tools and ctx.llm are ready here.
+}
+```
+
+If a required service disappears, for example during provider replacement, the plugin unloads automatically (ACTIVE → DISPOSED) and loads again when the service returns.
+
+## Automatic cleanup
+
+Every registration made through `ctx` is undone when the plugin unloads:
+
+```ts ignore-check
+export function apply(ctx: Context) {
+ // Event listener: removed automatically on unload.
+ ctx.on('some-event', handler)
+
+ // Custom resource: the returned disposer runs on unload.
+ ctx.effect(() => {
+ const connection = createConnection()
+ return () => connection.close()
+ })
+}
+```
+
+The framework tracks and disposes all of these operations:
+- `ctx.on(event, handler)` — event listener
+- `ctx.tools.register(tool)` — tool registration
+- `ctx.llm.registerAdapter(names, adapter)` — LLM adapter registration
+- `ctx.effect(() => cleanup)` — custom resource
+
+During unload, disposer invocation starts in reverse registration order, but multiple async disposers run concurrently and have no serial completion guarantee. Put order-dependent cleanup in one disposer returned from a single `ctx.effect()` and await its steps serially there.
+
+## Nested contexts
+
+`ctx.plugin()` creates a child Fiber that inherits the parent context but has an independent lifecycle:
+
+```ts ignore-check
+export function apply(ctx: Context) {
+ // Register a child plugin.
+ ctx.plugin(childPlugin)
+
+ // The child has its own Fiber and unloads with its parent.
+}
+```
+
+## Dispose semantics
+
+To stop a plugin instance early:
+
+```ts
+import type { Context } from 'cordis'
+
+declare const ctx: Context
+declare function myPlugin(ctx: Context): void
+
+const fiber = ctx.plugin(myPlugin)
+
+// Dispose it manually later.
+await fiber.dispose()
+```
+
+`dispose` guarantees:
+1. All registrations owned by the plugin are removed.
+2. Child plugins are recursively unloaded.
+3. The returned promise resolves after all asynchronous cleanup finishes.
+
+## Hot replacement (HMR)
+
+With `@cordisjs/plugin-hmr` loaded from `cordis.yml`, editing a plugin source file triggers:
+
+1. Unload the old plugin and clean up its registrations.
+2. Load the new code.
+3. Run the new `apply`.
+
+Because plugin registrations clean themselves up, hot replacement does not retain registrations from the old instance.
+
+## Example lifecycle
+
+```ts ignore-check
+export function apply(ctx: Context) {
+ console.log('plugin loading')
+
+ ctx.effect(() => {
+ console.log('effect registered')
+ return () => console.log('effect cleaned up')
+ })
+}
+```
+
+Loading prints:
+```
+plugin loading
+effect registered
+```
+
+Unloading prints:
+```
+effect cleaned up
+```
+

+# Services and dependencies
+
+English | [中文](service.zh.md)
+
+A service is a capability one plugin exposes to other plugins. `inject` declares the services a plugin requires.
+
+## What is a service?
+
+In Harness, `tools`, `llm`, and `agents` are services. Each is a named capability mounted on `ctx`:
+
+```ts ignore-check
+ctx.tools // ToolRegistry service
+ctx.llm // LLM service
+ctx.agents // Agent service
+```
+
+Any plugin can provide a service for other plugins to consume.
+
+## Consume a service
+
+Declare `inject` to use an existing service:
+
+```ts ignore-check
+export const inject = ['tools']
+
+export function apply(ctx: Context) {
+ // ctx.tools exists and is ready here.
+ ctx.tools.register(/* ... */)
+}
+```
+
+When `apply` runs, every service declared by `inject` is ready. If a service is not ready, the plugin waits instead of running.
+
+## Provide a service
+
+### Extend Service
+
+```ts
+import { Service, type Context } from 'cordis'
+
+export default class MetricsService extends Service {
+ static inject = ['llm'] // A service may depend on other services.
+
+ constructor(ctx: Context) {
+ super(ctx, 'metrics') // 'metrics' is the service name.
+ }
+
+ // Public service method.
+ record(event: string, value: number) {
+ // ...
+ }
+}
+```
+
+After loading this plugin, consumers access the service as `ctx.metrics`:
+
+```ts ignore-check
+export const inject = ['metrics']
+
+export function apply(ctx: Context) {
+ ctx.metrics.record('tool_call', 1)
+}
+```
+
+### Declare its type
+
+Use TypeScript declaration merging to type `ctx.metrics`:
+
+```ts
+import { Service, type Context } from 'cordis'
+
+declare module 'cordis' {
+ interface Context {
+ metrics: MetricsService
+ }
+}
+
+export default class MetricsService extends Service {
+ constructor(ctx: Context) {
+ super(ctx, 'metrics')
+ }
+
+ record(event: string, value: number) { /* ... */ }
+}
+```
+
+## Dependency behavior
+
+### Required and optional dependencies
+
+```ts ignore-check
+// Required: the plugin does not load while the service is absent.
+export const inject = ['tools']
+
+// Optional: omit inject and query with ctx.get() at the use site.
+export function apply(ctx: Context) {
+ const metrics = ctx.get('metrics')
+ metrics?.record('plugin_loaded', 1)
+}
+```
+
+### When a service disappears
+
+If a required service disappears while the application is running, for example because its provider unloads:
+
+1. Dependent plugins dispose automatically.
+2. They load again when the service returns.
+
+This prevents a plugin from calling a service that no longer exists.
+
+## Service isolation
+
+`cordis.yml` can isolate services so separate plugin groups see separate instances of the same service:
+
+```yaml
+- id: group-a
+ name: '@cordisjs/plugin-group'
+ group: true
+ isolate:
+ bash: true
+ config:
+ - name: '@deepseek-ai/dsh-bash-local'
+ config:
+ timeoutMs: 5000
+ - name: './src/plugin-a.ts'
+
+- id: group-b
+ name: '@cordisjs/plugin-group'
+ group: true
+ isolate:
+ bash: true
+ config:
+ - name: '@deepseek-ai/dsh-bash-local'
+ config:
+ timeoutMs: 60000
+ - name: './src/plugin-b.ts'
+```
+
+`plugin-a` and `plugin-b` each see the Bash instance in their own group, with no cross-group effect.
+
+## Built-in Harness services
+
+The repository generates the service names, public methods, and source locations in the [service catalog](../../../cordis-catalog/services.md). Use that catalog and the service's TypeScript interface while developing a plugin; do not maintain a second static list.
+
+## Next steps
+

+- [Capability layering](../practice/) — use services as capability interfaces

+# Three-layer capability design
+
+English | [中文](index.zh.md)
+
+When a capability is general enough to need replaceable implementations, such as Bash execution, Harness splits it into three packages: an **interface**, an **implementation**, and a **consumer**. Each layer can evolve or be replaced independently.
+
+## Bash example
+
+The Bash execution capability consists of:
+
+- **Interface** (`dsh-bash`) — defines Bash request and result shapes
+- **Implementation** (`dsh-bash-local`) — executes commands on the local machine
+- **Consumer** (`dsh-tool-bash`) — exposes the capability as a model-callable tool
+
+```
+┌─────────────┐ ┌──────────────────┐ ┌──────────────┐
+│ dsh-bash │────▶│ dsh-bash-local │ │ dsh-tool-bash│
+│ (interface) │ │ (implementation) │ │(consumer/tool)│
+└─────────────┘ └──────────────────┘ └──────────────┘
+ ▲ │
+ └────────────────────────────────────────────┘
+ inject: ['bash']
+```
+
+## Benefits of the split
+
+### Replace implementations
+
+One interface can have multiple implementations selected through `cordis.yml`:
+
+```yaml
+# Local execution
+- name: '@deepseek-ai/dsh-bash-local'
+
+# Or a future remote sandbox implementation
+# - name: '@deepseek-ai/dsh-bash-remote'
+# config:
+# endpoint: 'https://sandbox.example.com'
+```
+
+The interface and tool remain unchanged while the implementation changes.
+
+### Evolve independently
+
+- The interface changes rarely after its contract stabilizes.
+- Implementations can improve performance and security independently.
+- Consumers can change how they present the capability to the model.
+
+### Decouple dependencies
+
+- The implementation depends on the interface.
+- The consumer depends on the interface.
+- The implementation and consumer **do not depend on each other**.
+
+## Built-in three-layer capabilities
+
+| Capability | Interface | Implementation | Consumer |
+|------|-------------|------|---------------|
+| Bash | `dsh-bash` | `dsh-bash-local` | `dsh-tool-bash` |
+| Filesystem | `dsh-fs` | `dsh-fs-local` + `dsh-fs-policy` | `dsh-tool-fs` |
+| Web | `dsh-web` | `dsh-web-fetch-local` / `dsh-web-search-*` | `dsh-tool-web` |
+| Subagent | `dsh-subagent` | `dsh-subagent-spawn` / `dsh-subagent-fork` | `dsh-tool-subagent` |
+| Compaction | `dsh-compact` | `dsh-compact-basic` | The implementation consumes agent-loop extension events |
+
+## Develop a three-layer capability
+
+### Step 1: define the interface
+
+```ts ignore-check
+// packages/my-cap/my-cap/src/index.ts
+import { Service, type Context } from 'cordis'
+
+declare module 'cordis' {
+ interface Context {
+ myCap: MyCapService
+ }
+}
+
+export abstract class MyCapService extends Service {
+ constructor(ctx: Context) {
+ super(ctx, 'myCap')
+ }
+
+ /** Execute the capability. */
+ abstract execute(request: MyCapRequest): Promise
+}
+
+export interface MyCapRequest {
+ input: string
+}
+
+export interface MyCapResult {
+ output: string
+}
+```
+
+### Step 2: write an implementation
+
+```ts ignore-check
+// packages/my-cap/my-cap-local/src/index.ts
+import type { Context } from 'cordis'
+import { MyCapService, type MyCapRequest, type MyCapResult } from '@deepseek-ai/dsh-my-cap'
+
+class MyCapLocal extends MyCapService {
+ async execute(request: MyCapRequest): Promise {
+ // Concrete implementation.
+ return { output: request.input.toUpperCase() }
+ }
+}
+
+export const name = 'my-cap-local'
+
+export function apply(ctx: Context) {
+ ctx.plugin(MyCapLocal)
+}
+```
+
+### Step 3: write a consumer
+
+```ts ignore-check
+// packages/my-cap/tool-my-cap/src/index.ts
+import type { Context } from 'cordis'
+import { defineTool } from '@deepseek-ai/dsh-tools'
+
+export const name = 'tool-my-cap'
+export const inject = ['tools', 'myCap']
+
+export function apply(ctx: Context) {
+ ctx.tools.register(defineTool({
+ name: 'my_cap',
+ description: 'Execute my capability.',
+ parameters: {
+ input: { type: 'string', required: true },
+ },
+ async execute(args) {
+ const result = await ctx.myCap.execute({ input: args.input })
+ return [{ type: 'text', text: result.output }]
+ },
+ }))
+}
+```
+
+### Compose them in cordis.yml
+
+```yaml
+- name: '@deepseek-ai/dsh-my-cap-local'
+- name: '@deepseek-ai/dsh-tool-my-cap'
+```
+
+## Design points
+
+- **Do not split preemptively** — use three packages only when the capability needs replaceable implementations. A simple tool plugin does not.
+- **The interface owns Request/Result types** — implementations and consumers depend only on the interface package.
+- **Explicit > implicit** — resolve defaults in an explicit `resolve(request): Spec` step rather than hiding `?? default` expressions inside `run()`.
+
+## Next steps
+
+- [LLM adapter](./llm-adapter.md) — implement an LLM backend, a common capability interface extension

+# LLM adapters
+
+English | [中文](llm-adapter.zh.md)
+
+This guide connects a new LLM provider to Harness.
+
+## Overview
+
+An LLM adapter extends `LlmAdapter` and implements `stream()`, translating Harness's provider-neutral request into a provider API call and translating the response back into Harness chunks.
+
+## Minimal implementation
+
+```ts
+import type { Context } from 'cordis'
+import Schema from 'schemastery'
+import { LlmAdapter, type GenerateOptions, type StreamChunk } from '@deepseek-ai/dsh-llm'
+
+class MyAdapter extends LlmAdapter {
+ private apiKey: string
+
+ constructor(apiKey: string) {
+ super()
+ this.apiKey = apiKey
+ }
+
+ async *stream(options: GenerateOptions): AsyncIterable {
+ // 1. Convert options.messages to the provider format.
+ // 2. Call the streaming API.
+ // 3. Convert the response into StreamChunk values.
+ }
+}
+
+export interface Config {
+ apiKey: string
+ models: string[]
+}
+
+export const Config: Schema = Schema.object({
+ apiKey: Schema.string().required(),
+ models: Schema.array(Schema.string()).required(),
+})
+
+export const name = 'my-llm-adapter'
+export const inject = ['llm']
+
+export function apply(ctx: Context, config: Config) {
+ const adapter = new MyAdapter(config.apiKey)
+ ctx.llm.registerAdapter(config.models, adapter)
+}
+```
+
+## StreamChunk protocol
+
+`stream()` yields chunks using this protocol:
+
+```ts
+import { CallId, type StreamChunk } from '@deepseek-ai/dsh-llm'
+
+async function* exampleChunks(): AsyncIterable {
+ // 1. Start each content block with block-start.
+ yield { type: 'block-start', index: 0, blockType: 'text' }
+
+ // 2. Stream text through text-delta.
+ yield { type: 'text-delta', index: 0, text: 'Hello' }
+ yield { type: 'text-delta', index: 0, text: ' world' }
+
+ // 3. End each content block with block-end and the complete block.
+ yield {
+ type: 'block-end',
+ index: 0,
+ block: { type: 'text', text: 'Hello world' },
+ }
+
+ // 4. Tool-call block.
+ yield { type: 'block-start', index: 1, blockType: 'tool-call' }
+ yield {
+ type: 'tool-call-delta',
+ index: 1,
+ id: CallId('call-123'),
+ name: 'bash',
+ argumentsDelta: '{"command":"ls"}',
+ }
+ yield {
+ type: 'block-end',

+ // Alternatively, { kind: 'tool-calls' } requests tool execution.
+}
+```
+
+### Key rules
+
+- Every `block-start` has a matching `block-end`.
+- `index` increases from 0 and identifies content-block order.
+- A `tool-call-delta` carries raw JSON text in `argumentsDelta`, either all at once or over multiple chunks.
+- `finish` is the final chunk.
+- Emit `usage` before `finish`.
+
+## GenerateOptions
+
+`stream()` receives the exported `GenerateOptions` type. It includes the model, conversation history, system prompt, tool schemas, generation parameters, stop sequences, and abort signal; treat the TypeScript type exported by `@deepseek-ai/dsh-llm` as authoritative. Map supported fields to the provider API. If the provider cannot honor a field, throw `LlmError` with a stable code instead of silently dropping it.
+
+## Register an adapter
+
+```ts ignore-check
+ctx.llm.registerAdapter(['model-name-1', 'model-name-2'], adapter)
+```
+
+The first argument lists the model names handled by the adapter. If `cordis.yml` selects `model: model-name-1`, the service routes that request to this adapter.
+
+## Use it from cordis.yml
+
+```yaml
+- id: my-llm
+ name: './src/my-llm-adapter.ts'
+ config:
+ apiKey: !!js process.env.MY_API_KEY
+ models:
+ - my-model-v1
+ - my-model-v2
+
+- id: stdio-agent
+ name: '@deepseek-ai/dsh-stdio-demo'
+ config:
+ model: my-model-v1 # References the model registered above.
+```
+
+## Reference implementations
+
+The repository contains complete implementations:
+
+- `packages/llm/llm-deepseek/` — DeepSeek API adapter using the OpenAI-compatible format
+- `packages/llm/llm-pi-ai/` — Pi AI adapter using a different API format
+- `examples/echo-agent/src/mock-llm.ts` — minimal local teaching adapter
+
+Start with the mock adapter to study a complete chunk sequence without network behavior.
+
+## Error handling
+
+Adapters throw transport and protocol failures as `LlmError` values with stable codes. The agent loop preserves the error and code for diagnostics and policy; it does not convert an ordinary `Error` automatically. Every provider HTTP request must also merge `attributionHeaders()` and forward `options.signal`.
+
+```ts
+import {
+ attributionHeaders,
+ LlmAdapter,
+ LlmError,
+ type GenerateOptions,
+ type StreamChunk,
+} from '@deepseek-ai/dsh-llm'
+
+class HttpAdapter extends LlmAdapter {
+ constructor(private readonly endpoint: string) {
+ super()
+ }
+
+ async *stream(options: GenerateOptions): AsyncIterable {
+ const response = await fetch(this.endpoint, {
+ method: 'POST',
+ headers: {
+ 'content-type': 'application/json',
+ ...attributionHeaders(),
+ },
+ body: JSON.stringify({ model: options.model, messages: options.messages }),
+ ...options.signal ? { signal: options.signal } : {},
+ })
+ if (!response.ok) {
+ throw new LlmError(`Provider API error: ${response.status}`, 'PROVIDER_HTTP_ERROR')
+ }
+ // A real adapter parses the response and emits the complete chunk sequence.
+ yield { type: 'finish', reason: { kind: 'stop' } }
+ }
+}
+```

+# Configuration
+
+English | [中文](config.zh.md)
+
+Harness uses `cordis.yml` to describe which plugins an agent loads and the configuration passed to each one. The file composes capabilities; the generated configuration catalog records the fields and defaults each package actually supports, avoiding a second hand-maintained reference.
+
+## Start from a real configuration
+
+The repository examples are runnable configurations and the most reliable starting points for a new project:
+
+- [echo-agent](../../../examples/echo-agent/cordis.yml) uses a local mock model and needs no API key.
+- [repl-agent](../../../examples/repl-agent/cordis.yml) combines the DeepSeek model, Bash, filesystem, compaction, subagents, and workflows.
+- [acp-agent](../../../examples/acp-agent/cordis.yml) connects to editor clients over ACP.
+
+A minimal configuration is a list of plugin entries:
+
+```yaml
+- id: llm-deepseek
+ name: '@deepseek-ai/dsh-llm-deepseek'
+ config:
+ apiKey: !!js process.env.DEEPSEEK_API_KEY
+ models:
+ - deepseek-v4-flash
+
+- id: stdio-agent
+ name: '@deepseek-ai/dsh-stdio-demo'
+ config:
+ model: deepseek-v4-flash
+```
+
+## Plugin entries
+
+`name` identifies an npm package or a local module relative to `cordis.yml`; `id` gives the plugin instance a stable identity; and `config` supplies plugin-specific configuration. Set `disabled: true` to skip an entry temporarily.
+
+```yaml
+- id: local-tool
+ name: './src/my-tool.ts'
+ disabled: false
+ config:
+ toolName: my_tool
+```
+
+Plugins load in file order. Place plugins that depend on services after the applications or capability plugins that provide them. Missing models, tools, and plugins fail as early as possible instead of being silently ignored.
+
+## JavaScript values and environment variables
+
+The Cordis loader evaluates runtime expressions tagged with `!!js`. Keep API keys and other secrets in the gitignored `.env` file at the repository root, never in committed configuration.
+
+```yaml
+config:
+ apiKey: !!js process.env.DEEPSEEK_API_KEY
+ cwd: !!js process.cwd()
+```
+
+The tag is `!!js`, not `!js`.
+
+## Exact configuration reference
+
+The generated [plugin configuration catalog](../../config-catalog.md) lists every current field, type, and default. For composition concepts, continue to the [architecture](../../architecture.md) and [capability interfaces](../../capability-seams.md). To create a configuration, copy the closest entry from the [examples overview](../../../examples/README.md) and adapt it.

+# 配置文件
+
+[English](config.md) | 中文
+
+Harness 使用 `cordis.yml` 描述 Agent 加载哪些插件以及每个插件的参数。配置文件负责组合能力；每个包真正支持的字段和默认值由源码生成的配置目录负责记录，避免两份手写表格逐渐不一致。
+
+## 从真实配置开始
+
+仓库中的示例就是可以运行的配置，也是新项目最可靠的起点：
+
+- [echo-agent](../../../examples/echo-agent/cordis.yml) 使用本地 mock 模型，不需要 API key。
+- [repl-agent](../../../examples/repl-agent/cordis.yml) 组合 DeepSeek 模型、Bash、文件系统、压缩、子代理和工作流。
+- [acp-agent](../../../examples/acp-agent/cordis.yml) 通过 ACP 接入编辑器客户端。
+
+最小配置由一组插件条目组成：
+
+```yaml
+- id: llm-deepseek
+ name: '@deepseek-ai/dsh-llm-deepseek'
+ config:
+ apiKey: !!js process.env.DEEPSEEK_API_KEY
+ models:
+ - deepseek-v4-flash
+
+- id: stdio-agent
+ name: '@deepseek-ai/dsh-stdio-demo'
+ config:
+ model: deepseek-v4-flash
+```
+
+## 插件条目
+
+`name` 指定 npm 包或相对于 `cordis.yml` 的本地模块，`id` 为插件实例提供稳定标识，`config` 传入插件自己的配置。需要临时跳过某个条目时可设置 `disabled: true`。
+
+```yaml
+- id: local-tool
+ name: './src/my-tool.ts'
+ disabled: false
+ config:
+ toolName: my_tool
+```
+
+插件按文件中的顺序加载。依赖其他服务的插件应该排在提供这些服务的应用或能力插件之后；引用不存在的模型、工具或插件会尽早报错，而不是被静默忽略。
+
+## JavaScript 值和环境变量
+
+Cordis loader 使用 `!!js` 标签读取运行时表达式。API key 等凭据应放在仓库根目录、已被 Git 忽略的 `.env` 中，不能提交到配置文件。
+
+```yaml
+config:
+ apiKey: !!js process.env.DEEPSEEK_API_KEY
+ cwd: !!js process.cwd()
+```
+
+标签是 `!!js`，不是 `!js`。
+
+## 精确配置参考
+
+每个插件当前支持的字段、类型和默认值见自动生成的[插件配置目录](../../config-catalog.md)。理解插件如何组合可继续阅读[架构说明](../../architecture.md)和[能力接口](../../capability-seams.md)；要创建自己的配置，优先复制并修改[示例目录说明](../../../examples/README.md)中最接近的例子。

+# Introduction
+
+English | [中文](index.zh.md)
+
+DeepSeek Harness is a **plugin-based agent development framework** built on the [Cordis](https://github.com/cordiverse/cordis) microkernel. Its central idea is simple: **everything is a plugin**.
+
+## What it is
+
+Harness implements every capability an AI agent needs—including LLM calls, tool execution, session management, and subtask delegation—as a composable plugin. A `cordis.yml` file declares which plugins to load and how to configure them, assembling a complete agent.
+
+```yaml
+# Select the LLM backend
+- name: '@deepseek-ai/dsh-llm-deepseek'
+ config:
+ apiKey: !!js process.env.DEEPSEEK_API_KEY
+
+# Select the application template
+- name: '@deepseek-ai/dsh-stdio-demo'
+ config:
+ model: deepseek-v4-flash
+```
+
+## Who it is for
+
+### Application users
+
+To run an existing agent application, such as a coding assistant or conversational agent:
+
+1. Copy an example template.
+2. Add an API key.
+3. Run it.
+
+No code is required. See the [quick start](./quickstart.md).
+
+### Plugin developers
+
+To add a custom tool, a new LLM adapter, or another execution backend, write a plugin. Harness provides explicit extension interfaces and a type-safe development experience. See [development](../develop/basic/).
+
+## Core features
+
+- **Configuration only** — `cordis.yml` selects the capability set; changing a model or adding a tool is a configuration edit.
+- **Hot replacement (HMR)** — edit plugin code during development without restarting the process.
+
+## Technology
+
+- **Runtime**: Node.js ^22.19 or >= 24
+- **Language**: TypeScript (ESM)
+- **Framework**: Cordis
+- **Package manager**: pnpm workspaces (the repository pins pnpm 11)

+# Quick start
+
+English | [中文](quickstart.zh.md)
+
+This guide gets an agent running in five minutes.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) ^22.19 or >= 24
+- [pnpm](https://pnpm.io/) 11 (use Corepack to select the repository-pinned version)
+
+```sh
+# Check versions
+node -v # v22.19.x, or v24.x and newer
+corepack enable
+pnpm -v # 11.x
+```
+
+## Step 1: run echo-agent
+
+echo-agent needs no API key and runs after dependencies are installed.
+
+```sh
+# Clone the repository
+git clone https://github.com/deepseek-harness/deepseek-harness.git
+cd deepseek-harness
+
+# Install dependencies
+pnpm install
+
+# Start echo-agent
+pnpm run demo:echo
+```
+
+The process prints:
+
+```
+echo-agent ready. Type a message ("echo " triggers the tool).
+>
+```
+
+Enter:
+
+```
+> echo hello world
+```
+
+The model issues a tool call, and the echo tool returns the text in uppercase:
+
+```
+[tool call] echo({"text":"hello world"})
+[tool result] ECHO: HELLO WORLD
+```
+
+Your local environment is ready.
+
+## Step 2: use a real model
+
+Next, connect a real DeepSeek model and run the complete command-line agent.
+
+### Get an API key
+
+Get an API key from [DeepSeek Platform](https://platform.deepseek.com/).
+
+### Configure the environment
+
+Create a gitignored `.env` file in the repository root:
+
+```sh
+DEEPSEEK_API_KEY=sk-your-key-here
+```
+
+### Start repl-agent
+
+```sh
+pnpm run demo:repl
+```
+
+```
+agent REPL ready. Give it a coding task.
+>
+```
+
+This is a complete coding assistant that can read and write files, run commands, and delegate subtasks.
+
+Try a task:
+
+```
+> Create hello.js in the current directory, print "Hello from Harness!", and run it
+```
+
+## What happened
+
+echo-agent and repl-agent use the same application framework (`@deepseek-ai/dsh-stdio-demo`). Their `cordis.yml` files select different plugins and configuration. Custom agents use the same composition model.
+
+## Next steps
+
+- [Configuration](./config.md) — understand the `cordis.yml` format
+- [Develop a plugin](../develop/basic/) — build your own tool or backend

# compact/ — compaction capability family
-A three-package capability seam (see [capability seams](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): an abstract compaction interface, a backend that summarizes, and the model-facing tool that consumes it.

+A compaction capability family (see [capability seams](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): an abstract interface, a summarizing backend, a model-free tool-result pruning companion, and a deferred model-facing consumer. All **product** packages.

|---|---|---|
| `compact/` | Abstract compaction seam (interface + `compact/*` events + `CompactionResult`) | `ctx.compact` |
| `compact-basic/` | A backend: `ctx.tokenMeter` pressure + token-budget retention + `llm.stream()` summarization | (registers `ctx.compact`) |
+| `compact-tool-result-prune/` | Optional model-free head/middle/tail rewriting before summary compaction | `ctx.toolResultPrune` |
| `tool-compact/` (deferred) | Model-facing `/compact` tool over `ctx.compact` | (registers on `ctx.tools`) |
-The interface lives at `compact/compact/`, the backend at `compact/compact-basic/`. Unlike the bash seam, it depends on `dsh-session` and `dsh-llm` — its verbs are defined over a `Session` and its output is the `ContentBlock` vocabulary, so the contract cannot be expressed without naming them. That deviation from the "interface depends only on cordis" guidance is intentional and recorded in the [compaction capability-seam Agent Note](../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md). Token measurement is a reusable LLM-family service rather than a `CompactService` method; a template- or model-backed compactor can replace `compact-basic` without changing the meter or callers.

This backend owns the compaction policy:
- **Measurement** — the singleton `ctx.tokenMeter` prices the latest canonical logged envelope and current surface at one consumed-log revision. Post-step pressure therefore includes the actual system prompt, tools, prefix, routing, assistant completion, tool results, buffered context, and steering.
-- **Retention** — compact the oldest whole surface units while preserving a recent tail and balanced tool-call/result cuts through the [`dsh-compact` boundary helpers](../compact/README.md#tool-pairing-boundaries). Turn boundaries do not protect old steps inside a runaway turn. An open indivisible tail declines until it closes; a single unit larger than the budget remains out of scope.
+- **Model-free pruning** — after pressure or canonical overflow qualifies, the optional [`ctx.toolResultPrune`](../compact-tool-result-prune/README.md) service rewrites oversized tool results before range selection. Compact-basic remeasures through `ctx.tokenMeter`, skips summarization when pressure becomes safe, and otherwise summarizes the pruned surface. Below-pressure post-step checks never prune.
+- **Retention** — compact the oldest whole surface units while preserving a recent tail and balanced tool-call/result cuts through the [`dsh-compact` boundary helpers](../compact/README.md#tool-pairing-boundaries). Turn boundaries do not protect old steps inside a runaway turn. An open indivisible tail declines until it closes. The optional pruner can repair an oversized closed tool unit when its text-bearing result is the removable bulk; indivisible non-tool units and non-prunable tool remainders remain out of scope.
- **Convergence** — retry head-checkpoint compaction up to `compactionRetries`; reject a summary that does not shrink its source, and throw if retries cannot return below threshold.
- **Summarization** — a direct `llm/stream` call uses the configured provider/model pair and cap, falling back to the latest logged request target and then the agent target, without running the loop-only `agent/request` seam. The input transcript preserves non-text blocks as tagged placeholders; only returned text enters the checkpoint, excluding reasoning and tool calls that would leak private reasoning or create an orphaned call.
- **Framing** — the replacement user message marks established checkpoint context with `` tags. The raw summary remains on the provenance event, and later automatic cycles merge the prior checkpoint.
- **Lifecycle** — `compactRegion()` mutates `agent.session` and records its start, summary, replacement, and end. The serial `agent/post-step` listener checks pressure after successful output and tool work are durable but before `step/end`.

Cancellation remains authoritative after any progress.
The protected `summarize()` method is the sole subclass hook. A template- or remote-summarizer subclass can override it while pressure, retention, provenance, shrink validation, and shadowed-token accounting stay on `ctx.tokenMeter`. The hook returns the summary blocks together with the call envelope it used (`{ summary, provider, model, maxTokens? }`), which is logged on `compact/summary`.

+# @deepseek-ai/dsh-compact-tool-result-prune
+
+The replay-safe model-free pruning service (`ctx.toolResultPrune`). It rewrites over-budget `tool/result` surface nodes to a bounded head, a fixed omission marker, and a bounded tail while retaining the full original event in the append-only session log.
+
+This is a concrete companion to [`dsh-compact-basic`](../compact-basic/README.md), not a compaction backend or model-facing tool. Compact-basic reads it through optional `ctx.get('toolResultPrune')`, so either package remains independently composable.
+
+## Service API
+
+`pruneSession(session)` scans one stable snapshot of the current surface. Every over-budget tool result is replaced by one newly appended `tool/result` carrying `{ surfaceOp: { op: 'replace', start: originalSeq, end: originalSeq }, sourceEventSeqs: [originalSeq] }`. The replacement spreads the complete original data and changes only `content`, preserving `turn`, `step`, `callId`, error fields, `meta`, and later data additions. The original event remains available for persistence, replay, and exact-log inspection.
+
+The method throws synchronously when the session rejects a replacement. Replacements committed earlier in the pass remain durable.
+
+`measureContent(blocks)` counts Unicode code points in `text` blocks. `pruneContent(blocks)` returns the bounded replacement or `null` when content is already within the threshold. Non-text blocks are retained at their original relative positions; text slicing never splits a UTF-16 surrogate pair, though it can split a multi-code-point grapheme cluster.
+
+Every emitted result has exactly the configured head budget, fixed marker, and tail budget in text code points, is no larger than `thresholdChars`, and is strictly smaller than the triggering input. A second pass therefore emits no replacement.
+
+## Config
+
+Unrecognized keys fail at plugin construction. Resolved config is detached and deeply immutable.
+
+| Key | Required | Meaning |
+|---|---|---|
+| `thresholdChars` | no (default `8192`) | Prune when combined text exceeds this many Unicode code points. |
+| `headChars` | no (default `4096`) | Leading Unicode code points retained. |
+| `tailChars` | no (default `1024`) | Trailing Unicode code points retained. |
+
+All values are integers; the threshold is positive and head/tail are non-negative. `headChars + marker + tailChars` must fit within `thresholdChars`, so a valid configuration can prune every over-budget result without growth or repeated rewriting.
+
+## Usage
+
+```ts
+import type { Context } from 'cordis'
+import ToolResultPruneService from '@deepseek-ai/dsh-compact-tool-result-prune'
+
+export function apply(ctx: Context): void {
+ ctx.plugin(ToolResultPruneService)
+}
+```
+
+## Model Experience
+
+### Pruned tool result
+
+#### What the model sees
+
+Once a compaction trigger qualifies, future requests see the retained head, `\n\n[... tool result middle pruned ...]\n\n`, and retained tail in place of the removed text. Rich blocks keep their order. The model does not see a second copy of the original.
+
+#### Token effect
+
+Each rewritten tool result has at most `thresholdChars` text code points. Pruning itself makes no model call; compact-basic skips summarization when the remeasured request falls below pressure, otherwise the summarizer reads the pruned surface.
+
+#### KV Cache effect
+
+Replacing an earlier result invalidates reuse from the first changed token. The pruned prefix is eligible for reuse while its route, envelope, and preceding history remain identical.
+
+## Known Limitations and Deferred Work
+
+- **Character budgets are not token budgets** — provider token density varies, so `ctx.tokenMeter` remains the authority for deciding whether pruning relieved request pressure.
+- **Pruning is syntactic** — it retains the beginning and end without interpreting which middle lines are semantically important.
+- **Grapheme clusters can split** — code-point slicing protects surrogate pairs but does not perform locale-aware grapheme segmentation.

## Known Limitations and Deferred Work
- **No model-facing consumer tier yet** — `@deepseek-ai/dsh-tool-compact` (the `/compact` tool) is deferred; compaction is reachable only via direct `ctx.compact` calls or a backend's auto listener.
-- **Single-unit overflow is out of contract** — one indivisible unit (a closed tool pair or a large pasted `user/message`) alone exceeding the budget cannot be compacted.
+- **Some single-unit overflow is out of contract** — balanced summary compaction cannot split one indivisible unit. The optional pruning companion can still repair a closed tool pair when text-bearing tool-result bulk is removable; a large non-tool node or a tool unit whose non-prunable remainder is oversized cannot be compacted.
- **An envelope that alone approaches the window is not surface-compaction work** — compaction shrinks derived history, never the system prompt, tools, or session prefix.

The invariants plugin checks the remaining cross-record and cross-seam rules that Session does not own.
Session-log assertions run during Cordis `internal/dispatch`, while `Session.append()` is resolving the `session/event` callback snapshot but before it pushes the candidate into the log. A valid transition is staged by exact event identity and applied to the live trace only when that same committed event reaches the plugin's contained post-commit listener. A later internal dispatch check can therefore veto without advancing either the log or the invariant trace, while ordinary `session/event` observer failures remain observe-only.

- * Generate (and verify) the website API reference under `website/zh-CN/api/`.

- * it. The hand-written hub `api/index.md` sits OUTSIDE the generated subdirs
- * (`api/cordis/`, `api/harness/`), so the orphan sweep never touches it. Two tiers:
- *
- * - `api/cordis/*` — the vendored cordis framework surface (Context, Events,
- * Fiber, Registry, Service), driven by the CORDIS_PAGES manifest below.
- * Members come from the real class declarations and the `declare module
- * './context.ts'` interface merges (the typed `ctx.*` surface a plugin
- * author actually sees).
- * - `api/harness/*` — one page per `ctx.` harness service (walked from
- * every `declare module 'cordis'` Context merge under `packages///src`),
- * plus `events.md` listing every harness event grouped by scope.
- *
- * Prose comes from the JSDoc; the generator HARD-ERRORS (aggregated) when a
- * rendered member lacks a summary, a parameter lacks `@param`, or a non-void
- * annotated return lacks `@returns` — so a vendor sync or a new service method
- * cannot land undocumented without CI going red. Pages are English (the
- * planned zh translation flow arrives separately; see docs/i18n/README.md).
- *
- * Signature fences use the ` ```ts website-api ` info string and retain the
- * declaration's original source JSDoc. doc-typecheck only processes its known
- * info strings, so these bare (non-compilable) fragments are skipped there,
- * while VitePress still highlights the `ts` token. The sidebar fragment
- * `website/.vitepress/config/api-sidebar.json` is generated alongside so
- * navigation can never drift from the page set.

-/**
- * Doc-sync gate: verify the fenced ```yaml examples in the website against
- * the loader and the workspace truth. A `cordis.yml` example that names a
- * plugin that does not exist, or passes a config key the plugin never
- * declared, is worse than no example — it fails silently for the reader.
- *
- * Scope: `website/zh-CN/**/*.md`, EXCLUDING `website/zh-CN/api/**` (the api
- * pages are generator-owned — their yaml examples are verified at generation
- * time by a later stream, not re-checked here). Blocks opt out with
- * ` ```yaml ignore-check ` (same philosophy as doc-typecheck's opt-out: the
- * count is reported, an unchecked block is a visible decision, not a silent
- * hole — placeholder plugin names in tutorials are the legitimate case).
- *
- * Each checked block is parsed with the loader's REAL schema —
- * `JSON_SCHEMA` extended with the `!!js` scalar type exactly as
- * vendor/include/src/index.ts declares it — so `!!js process.env.X` parses
- * here iff it parses at runtime. Then:
- *
- * - Root is an ARRAY → a cordis.yml entry list. Every item must be a mapping
- * with a string `name` and only the keys `EntryOptions` declares
- * (vendor/loader/src/config/entry.ts plus the isolate.ts merge:
- * id, name, config, group, disabled, inject, intercept, isolate).
- * - `./` / `../` names are illustrative local plugins — existence is not
- * checkable, skip. `group:*` names are loader built-ins; their `config`
- * is itself an entry list and is recursed into.
- * - Any other name must be a real workspace package (`packages/*/*` and
- * `vendor/*` package.json names).
- * - For `@deepseek-ai/dsh-*` names the config-catalog generator is the
- * truth: kind `config` → the yaml `config`'s top-level keys must be
- * properties of the declared config type (member names of the first
- * catalog paste ∪ top-level segments of the runtime schema keys);
- * config-free kinds → a non-empty `config` mapping is a violation;
- * seam/library kinds → name existence only (loading one directly is
- * dubious, but that is a docs-prose concern, not this gate's).
- * - Root is a MAPPING or scalar → a fragment (e.g. a bare `config:` excerpt):
- * syntax check only.
- *
- * This is a checker, not a fixer: it reports `file:line message` and exits 1.
- *
- * Run: `tsx scripts/verify-website-yaml.ts`.
