Every conversation request's non-content half (system prompt, tool schemas, call config — the EpochHeader) is now recorded in the session log: a 'request/header' full snapshot (reason 'initial' | 'resume' | 'fallback') anchors the fold at conversation birth and process boundaries, and 'request/header-delta' events (system line-trim, name-keyed tools delta, whole config) encode mid-run changes. The pure trio — foldRequestHeader / diffHeader / applyHeaderDelta — reconstructs the header any request was built under from the log alone; the writer contract round-trip-verifies every delta with a 'fallback' snapshot when the encoding cannot express a change (pure tool reordering), so a well-formed log always folds cleanly. Canonical absence: empty system and empty tools normalize to absent fields, matching request builds. Persistence and cordis catalogs regenerated; SessionEventMap paste and EpochHeader added to the core-data-structures session page.
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.
