Tianyi Cui 1a1ce734ba feat(acp-example): add record/replay llm/stream plugin for snapshot tests
Introduces examples/acp-agent/src/llm-replay.ts, a function/namespace plugin
that installs a single llm/stream waterfall listener. In record mode it tees
the real model's StreamChunks into a per-scenario llm.json (flushed atomically
after EACH stream, since the snapshot subprocess is SIGKILLed and start.ts has
no disposal path). In replay mode it short-circuits the waterfall and serves
recorded streams back positionally — the Nth stream() call gets the Nth entry —
so a snapshot test can drive the real agent with no API key.

Each fixture entry is a discriminated record {chunks|throw|hang} so it can
replay BOTH branches of the LLM failure contract (throw from stream() vs a
finish-error chunk) plus cancellation. A throw entry carries the prefix chunks
emitted before the throw, replayed before the error, so a mid-stream failure
(partial output then STREAM_CLOSED) reproduces what the loop saw live.

Fail-loud on a missing or exhausted fixture (never a silent skip). Unit tests
drive the real LlmService waterfall (record tee, ordered replay, the three
entry kinds, partial-then-throw, fail-loud, event-driven abort, HMR-safety).
Broadens the unit vitest include to examples/*/tests and registers the plugin
+ snapshot tests as knip entries. Per docs/rfc/implemented/2026-06-19.

DeepSeek Harness

Monorepo for the DeepSeek Harness group.

Projects

  • DeepSeek Code — DeepSeek's coding agent product.

Development

This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.

pnpm install
pnpm run test          # vitest
pnpm run demo:echo     # runnable echo-agent example (no API key needed)
pnpm run demo:coding   # the real DeepSeek coding agent (needs DEEPSEEK_API_KEY)

For humans, start with the development guide for local setup, hooks, environment variables, and quality gates, then read the architecture design before package work. Local context lives in packages/ and vendor/.

For agents, follow AGENTS.md.
