Codex round-2 findings: - A committed test now proves the REAL plugin fiber (not a direct apply) owns the provider-lifecycle listeners: disposing a mounted tool's fiber unmounts the tool and leaves the provider intact, and a fiber disposed while WAITING never zombie-mounts when its provider arrives later. - TODO(subagent-dup-toolname) records the invalid-config blast radius of two waiting fibers sharing a toolName (the duplicate throw propagates through subagent/provider-added and rolls back the provider). - CONTEXT.md drops its creation-history sentence; the RFC's acceptance checklist becomes present-tense shipped invariants (docs/AGENTS.md writing rules).
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 before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
