Codex diff review, round 1, two (A) findings: - The agent/request fallback resolved the RAW seed object — on later steps the session's cached header fold — so a delegating listener (await next(), mutate, return) could rewrite the fold in place and the change would compare as already-baseline: no delta logged, the persisted log unable to reconstruct the request (the dev invariant would fire on the divergence, but the log would still lie). One structuredClone'd, deep-frozen seed now serves both the listener chain and the fallback — in-place shaping after delegation throws — and Session.requestHeader() freezes its fold on update, so the leak class is unrepresentable from either side. Pinned by a loop-level delegating-mutator test. - Doc sweep for the old contract: agent README's event row (mutate GenerateOptions / tool filtering → frozen config seed, replacement out, logged header), compact-basic's module JSDoc (summarize routed through agent/request → direct one-shot at llm/stream), and architecture.md's event-domain line (request mutation → call-config shaping).
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.
