The reconstructability RFC is the principle's home: model-visible ⟺ logged in both forms, the mechanism (boundary derivation + header fold), the enforcement (write-time round-trip guard, the dev invariant), the corollaries ranked (prefix-cache stability first), the MiniCode lineage with the provenance arrow inverted, and the alternatives it beat — including the stateful transmission client whose three-design archaeology lives in PR #162. Placements per the one-home-per-fact taxonomy: a standing-order line in root AGENTS.md (with displacement trims to stay inside the 1,575-word ceiling), the principle statement in architecture.md § Session Log and its Turn Flow lines (condensed to the ratcheted 1,630 ceiling), the request-envelope section in core-data-structures/core.md with the LlmCallConfig paste, both review-requested FIXMEs (FIXME(call-config-shape) beside the type, FIXME(catalog-verbs) at the catalog's drift-gate note), cookbook rows redirected off agent/request (tool filtering → system-prompt/assemble, plan-mode prompt → sections/ inject()), and the llm/stream JSDoc stating the frozen-request contract. RFC index and all generated catalogs regenerated.
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.
