ds-review-bot critical (follow-up): on the first step of a resumed or seeded/forked instance, auto-compaction ran before runStep composed this instance's prefix, so the gate read the PREVIOUS instance's logged prefix from the header fold — a contributor that grew across resume/fork (skills added, AGENTS.md grown: exactly the environment-dependent case) could under-gate and ship an over-window first request. The loop now composes agent/session-prefix before the instance's first agent/pre-step (still once per instance; runStep just reads the cache), and agent/pre-step carries the composed prefix to its listeners. CompactService.compactIfNeeded gains the sessionPrefix parameter; BasicCompactService.estimatePressure gates on the handed value — the header-fold read is gone, so the estimate is exact at every step including a resumed/forked instance's first. Composition moving before the boundary snapshot also means a composing listener's session append now joins the CURRENT request (documented on the seam). New coverage: composition precedes pre-step and the seam receives the composed prefix; cancel and disposal landing inside the composition window drop the step cleanly; the compact gate test hands the prefix directly.
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.
