Supersedes the single-slot staging the execution-identity fix (06c5f17e)
kept: the one pending slot needed a mismatch-drop branch plus a defensive
coverage-ignored finally to manage orphans, and it carried a latent trap —
under the loop's documented parallel-execution TODO, two in-flight capture
trips would overwrite the slot and BOTH be dropped.
Staging in a WeakMap<ToolExecution, {value}> makes the stale-stage class
structurally impossible instead of managed: an entry orphaned by an outer
short-circuiting listener can never match a different execution's lookup
(whatever call id that execution carries), needs no drop bookkeeping (the
map reclaims it with the execution object), and staging cannot cross-clobber
under parallel execution. Staging is the only layer this future-proofs — a
parallel cut would still owe its own single-accept rule for the captured
value, which is documented rather than claimed. Behavior is pinned by the
existing orphan/call-id-reuse regression tests, which pass unchanged; the
commit listener loses two branches and the v8-ignore.
DeepSeek Harness
English | 中文
The DeepSeek Harness SDK is a plugin-based SDK for building agent harnesses.
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:repl # REPL agent demo (needs DEEPSEEK_API_KEY)
pnpm run demo:acp # ACP server agent demo (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 and documentation graph index before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
