Repeated full-repo gate executions in agent sessions traced to one habit: piping a long command through a filter, losing the failure detail, and re-running the whole gate to recover it — paying both the gate again and an extra agent round-trip. The rule lands the full output in a temp file, prints the summary, and auto-expands capped failure context on non-zero exit in the SAME invocation. Fits the existing 1802-word ceiling after condensing (1800).
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.
