Treat a fallback kill refusal as successful termination when the child already carries an OS exit marker. Windows maps Node's supported signal names to forced termination, so the requested signal can end the process between the launcher error race and its fallback SIGKILL. Drain inherited stdio, the ACP parser, and in-flight callbacks before propagating the original child error in either exit-race path. Preserve AggregateError reporting only for a refused fallback while the process is still live, and add a deterministic cross-platform regression for that ordering.
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.
