The native adapter's route was named deepseek, colliding with pi-ai's catalog provider of the same name, so the two DeepSeek paths could never be mounted side by side. The web settings page needs both configurable at once. Compositions, fixtures, goldens, scaffolding defaults, and docs all move together (pre-release, no shim); TUI/session-query-spill/ missing-credential goldens re-recorded through their keyless refresh modes because provider-name length shifts box padding and spill truncation points.
acp-agent example
English | 中文
Automation-oriented Agent Client Protocol server over JSON-RPC stdio. It is intended for parent agents, subagent providers, and other programmatic clients, not as the product UI.
pnpm run demo:acp # needs DEEPSEEK_API_KEY (repo-root .env or env)
pnpm run demo:code-mode acp # same protocol with the Code Mode tool transport
The leaf loads the ACP app, DeepSeek adapter, sandboxed bash and filesystem stacks, one-shot approval policy, compaction, subagents, workflows, hooks, a derived session-query index, and repeat guard. The app creates one fresh agent per session/new, persists sessions to JSONL, and keeps stdout protocol-pure. session-query.cordis.yml explicitly opts into the workspace-authorized query tools and generic timeout/spill policies for their dedicated snapshot; fs.cordis.yml adds spill storage for filesystem scenarios, code-mode.cordis.yml adds run_code and its generated TypeScript SDK, and web.cordis.yml adds the web seam, the local fetch provider, web_fetch, and a loopback HTML fixture server for the web-fetch snapshot.
Protocol channel
Stdout carries only newline-delimited ACP JSON-RPC. @deepseek-ai/dsh-acp-demo installs no stdout logger; leaf additions must use stderr for diagnostics.
The automation contract — supported methods, baseline prompt content, committed-text output, and the intentionally absent UI surfaces — lives in @deepseek-ai/dsh-acp.
Session workspaces and permissions
Each session/new supplies an absolute cwd. Sandboxed bash and filesystem mutations resolve workspace-write against that session cwd, so concurrent sessions can use separate project roots; platform temporary roots remain shared writable scratch space (sandbox contract). DSH_PERMISSION_MODE selects workspace-write or danger-full-access for deployment and tests.
Under workspace-write, a model retry requesting wider sandbox access triggers session/request_permission with allow_once and reject_once. The client decides programmatically; dismissal or an unavailable answer fails closed. The selected outcome applies only to that retry and is recorded through the normal tool-result/audit path. The server never exposes a permission picker or persists client policy.
Snapshot tests
This example owns the ACP snapshot suite. It boots the real automation server, replays committed model streams through dsh-llm-replay, and compares both normalized protocol output and re-persisted session logs. Recording uses the real model; refresh reuses committed replay input. Overrides cover throw/hang behavior, and optional workspace/ fixtures seed world-state checks.
Most scenarios pin backend behavior rather than ACP-specific behavior; the automation-only ACP decision owns why that coverage remains transport-coupled.
