Further lifecycle/safety hardening of the local provider: - Tear the instance down when the initialize handshake is aborted, so a poisoned pending `ready` can't make later queries for that workspace re-wait. - Make the serialized-queue wait itself abortable, so a query blocked behind hung earlier work can still observe its own timeout. - Spawn the server detached and signal the whole process group on teardown, so helper processes (e.g. tsserver) can't outlive dispose(). - Open the source with O_NOFOLLOW and cap the read at maxDocumentBytes+1, closing the symlink-swap and concurrent-grow windows the fd-based read left open. - Honor an already-aborted signal before any host I/O or startup. - Validate maxStderrBytes positive at load; surface the retained stderr tail in the "language server exited" error so a fatal startup diagnostic is visible.
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.
