A reviewer found that window 2 (a cancel from a synchronous agent/status('running')
listener) had the same early-whenIdle() race that window 1 already guards: it
unconditionally `setStatus('idle')` + continue, which settles `whenIdle()`
waiters — so if the running listener cancels AND queues replacement work, the
waiter resolves while the replacement is still queued-and-unrun (the next
iteration runs it later, but the caller already observed quiescence).
Mirror window 1: after clearing the marker, only `setStatus('idle')` when
nothing new is queued; otherwise fall through to run the queued replacement
(status is already `running`), so `whenIdle()` resolves on that turn's
running→idle. Regression test reproduces the reviewer's interleaving (running
listener cancels A, sends B; whenIdle() resolves only after B ran).
Also syncs the cancellation contract in the two ACP RFCs that describe the live
behavior: `session/cancel` is the queue-aware `agent.cancel()` (drops an
about-to-start turn), not the old best-effort `agent.abort()` pre-step
limitation.

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.
pnpm install
pnpm run test # vitest
pnpm run demo:echo # runnable echo-agent example (no API key needed)
pnpm run 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/.
