Adds fast-check + one tests/properties.spec.ts per protocol-shaped package (llm/BlockAssembler, session, tools/schema DSL, agent-loop scheduling). The tools suite includes the RFC 001<->005 composition property (generated args satisfying a spec pass validateArgs), closing the validator/InferArgs drift risk from ADR 0011. Loop properties are deterministic (settle on agent/status, no sleeps). The BlockAssembler suite found a real bug on first run: a duplicate block-end at the same index overwrote an already-flushed block, so the streamed prefix disagreed with final blocks(). Fixed (first close wins, matching the existing straggler rule) + regression test. Graduates RFC 001 -> ADR 0013.
DeepSeek Harness
Monorepo for the DeepSeek Harness group.
Projects
- DeepSeek Code — DeepSeek's coding agent product.
Development
This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.
yarn install
yarn test # vitest
yarn demo:echo # runnable echo-agent example (no API key needed)
yarn demo:coding # the real DeepSeek coding agent (needs DEEPSEEK_API_KEY)
