Implement the tighten-hook-protocol-contract RFC (moved to implemented/): - HookDialect narrows to 'claude' | 'codex': the 'native' variant had zero producers (native plugins on the seams write no hook/* provenance), and the dialect is defined as the bridge that ran the hook. - HookOutput.suppressOutput is gone: the codec parsed it and every path discarded it with no warn and no deferral — hook stdout never enters a transcript, so there is nothing to suppress. - hook/result.durationMs is gone: durable timing telemetry with no reader that the snapshot normalizer had to scrub as replay noise. With no duration to measure, runHook loses its injected now clock and the single-field RunHookResult wrapper — it returns the HookOutput directly. The committed hook fixtures had the field stripped mechanically (field-only diff); the stdout goldens never carried it. - The bridges' double-defaulted defaultTimeoutMs config knob is replaced by one reference-default constant, DEFAULT_HOOK_TIMEOUT_MS, exported from the lib's runner and applied inside runHook; per-hook timeoutSec stays the override surface. - The hook/result semantics move into the lib that declares the event: HookResultRecord now carries the decoded HookOutput and appendHookResult derives the decision string (decision ?? stop-on-continue:false ?? pass) and the 500-char stderrSummary truncation; both bridges delete their byte-identical private copies. The snapshot suite passes against the existing goldens, proving the derived values are unchanged. - Rider: BLOCKING_EXIT_CODE is codec-internal again (zero importers). Amend the hook-protocol-lib and hook-snapshot-matrix RFCs to the new facts, update the lib/bridge READMEs and the session.md event tables, and retarget the affected unit tests (including new lib-level coverage of the derivation rules).
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 before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
