Final review pass on the local provider: - Tear the instance down when `initialize` REJECTS (utf-8 negotiation, malformed result), not only on abort, so a permanently-rejecting `ready` is never pooled. - Use the group-aware SIGKILL on a framing failure so helpers are reached. - Validate maxMessageBytes and maxDocumentBytes positive at load alongside the other byte caps. - Fix the location renderer's outside-workspace check to match a `..` segment exactly, so an in-workspace path like `..generated/a.ts` stays relative. - Document the accepted ancestor-directory symlink-swap TOCTOU under the trusted-host model (O_NOFOLLOW guards only the final component).
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.
