llm.registerAdapter, agents.register, sessions.create, systemPrompt.section, systemPrompt.tools, and tools.register each mutated state, emitted a change event, then returned the disposer. In Cordis a synchronous throw before the effect returns its disposer leaves nothing for the fiber to collect, so a throwing change-listener leaked the registry entry permanently — HMR/dispose could not clean it, and the duplicate-name/already-exists check stayed wedged until restart. Convert each to the generator-effect pattern already proven in AgentLoop.create: mutate state, `yield` the disposer that undoes it (collected before the next step runs, so it is torn down if a later step throws), THEN emit the change event. The existing duplicate-name throws are unchanged — they fire before any mutation, so they correctly leak nothing. No public API change: generator effects are still synchronous SyncEffects and register() keeps returning its fire-and-forget disposer wrapper. Tests: a listener-throw rollback test for all six methods — register with a change-listener that throws, assert the call throws AND the registry is clean (entry absent; a subsequent listener-free register of the same name succeeds and contributes exactly once). For systemPrompt (no duplicate-name check) the two tests assert assembly is clean. Verified each fails against the pre-fix emit-before-return-disposer form.
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)
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/.
