Timeout timing/classification was re-implemented three ways across the tool-bearing capabilities, with the fusion of timeout+cancel and the timeout-vs-cancel reason recovery being the error-prone parts. Extract that shared half into a zero-dependency @deepseek-ai/dsh-timeout library (clampTimeout/deadline/timeoutOf/TimeoutReason) and leave the non-shareable hard-kill in each capability, per the timeout-library RFC. bash: run() owns the deadline; runBash drops its killTimer and no longer classifies (SpawnSpec/SpawnOutcome lose timeoutMs/timedOut/aborted), so the public timedOut/aborted booleans become mutually-exclusive first-abort classifications. web_fetch: the hand-rolled controller/timer/listener/ signal.reason dance is replaced by provider-owned deadline/timeoutOf, keeping the WEB_FETCH_TIMEOUT / WEB_ABORTED contract. fs stays timeout-free (README states why).
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.
