Codex round-2 review found three adjacent fail-open shapes: - Wrapped function expressions escaped classification: parentheses, as/satisfies casts, and non-null assertions are now peeled before the arrow/function test (initializers and default exports), and a single-call-signature type literal counts as the surface signature. A literal mixing call/construct signatures with anything else is refused outright — no single signature to hold the tags against. - The blanket 'export import X = N.member' skip was unsound (the target can be a non-exported namespace member no walk visits): an alias now documents itself. - The heritage extra-parameter duty missed binding-pattern extras, which no base declaration can name: they now trigger the standard binding-pattern violation. Five new negative-path tests pin the closed shapes; module doc and RFC updated.
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.
