The read tool's isConcurrencySafe rationale called the fs/observed recorder "commutative" and said concurrent reads "converge to one observed version", overstating the guarantee: the WeakMap record is last-writer-wins. Safety comes from write/edit re-checking the version in their in-lock CAS (a stale observation only forces a later edit to fail closed with FS_STALE_VERSION), as the RFC already states. Align the read comment, the ToolDefinition JSDoc, both READMEs, and the regenerated catalogs.
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.
