The definitive sweep (audit every AGENTS.md mention in packages/, docs/, examples/, scripts/) found thirteen more citations of relocated policy and two citations of rules that never existed as quoted: - with-key policy comments (web deepseek/perplexity e2e headers) -> docs/testing.md; real-impl-over-mock comments (acp harness, load, stream-update specs) -> docs/testing.md; defensive-pattern quotes (acp index.ts x3, stream-update) -> docs/defensive-patterns.md. - md-tier repoints: real-api-e2e RFC, tool-schema-catalog RFC, postmortem 0001 guardrail row, adding-a-package cookbook, drop-bash-output-spill-files RFC, acp-subagent-backend RFC phrasing. - Two false attributions dropped in favor of self-contained reasoning: tool-todo's 'don't validate scenarios that can't happen' and the bash-stdin-env RFC's 'Don't add features beyond what the task requires' (neither rule ever existed under those names). - Citations of the two 'not golden truth' doctrines stay: those bullets survive verbatim in the root conventions. Note: packages/support/ui-stdio readline TTY spec flakes under full coverage on a heavily loaded box (passes standalone and passed the same tree's coverage run minutes earlier); untouched by this stack.

Cookbook: adding a workspace package
The file-by-file checklist for a new @deepseek-ai/dsh-<name> package. (Verified by the bash and adapter packages; if it drifts, fix it here.)
1. Create the package
packages/<group>/<pkg>/
package.json # copy from packages/core/tools, adjust name/description/deps
tsconfig.json # extends ../../../tsconfig.base.json, rootDir src,
# outDir lib/types, references: ../../../vendor/cosmokit,
# ../../../vendor/cordis (+ ../../../vendor/schemastery if
# you use Config, + ../../<group>/<dep> for each dsh dep)
src/index.ts # service default export or plugin (name/inject/apply/Config)
tests/<x>.spec.ts
README.md # service API, events, extension points, design notes
Choose an existing group when one matches the package's role (core, llm, bash, compact, subagent, todo, session-persistence, ui, util, or support). A new group is allowed, but it is a pure container: no package.json, no source files, and packages still sit exactly one level below it.
package.json invariants (enforced by pnpm run constraints / scripts/check-workspace-constraints.ts): private: true, version: 0.0.1, type: module, main: "lib/index.js", types: "lib/types/index.d.ts", exports["."].types: "./lib/types/index.d.ts", exports["."].default: "./lib/index.js", cordis in BOTH peerDependencies and devDependencies (same range). Mirror every dsh peer dependency in devDependencies. schemastery goes in dependencies (it is a runtime validator), matching agent-loop. The files list is precise: lib/index.js, lib/types/**/*.d.ts, lib/types/**/*.d.ts.map, and src; do not publish lib/types JS or JS-map intermediates or stale root declaration files. CLI app packages with a package bin include lib/bin.js immediately after lib/index.js in files.
In-package relative imports use explicit .ts specifiers in source (for example, export * from './types.ts'). The compiler rewrites those to .js in emitted JS and leaves explicit .ts specifiers in declarations, which standard NodeNext/Node16 TypeScript consumers resolve to the sibling .d.ts files.
2. Register it in the root configs
| File | Change |
|---|---|
tsconfig.base.json |
no edit for an existing group; for a new group, add a ./packages/<group>/*/src candidate to the @deepseek-ai/dsh-* wildcard |
tsconfig.json |
add { "path": "./packages/<group>/<pkg>" } to references |
tsconfig.build.json |
add { "path": "./packages/<group>/<pkg>" } to references |
knip.json |
only if the package has non-*.spec.ts entries (e.g. *.e2e.ts → add a per-workspace override like packages/llm/llm-deepseek) |
Covered automatically by globs or package-manifest discovery — no edits needed: root package.json workspaces, scripts/publint-all.ts, tsdown.config.ts, vitest.config.ts, eslint.config.mjs, scripts/check-workspace-constraints.ts.
3. Decide the package topology
For a swappable capability, split interface / implementation / consumer into separate packages (see docs/architecture.md § "Capability seams" — the bash trio is the template). A single-purpose plugin stays one package.
4. Verify
pnpm install # registers the workspace
pnpm run constraints && pnpm run typecheck && pnpm run lint
pnpm run test:coverage # 100% per-file over src (types.ts exempt)
pnpm run build && pnpm run hygiene
Test expectations: every registry/registration needs an HMR-safety test (register from a child fiber, dispose it, assert cleanup). Excessive tests are welcome — see docs/testing.md.
