An omitted maxDepth meant unbounded recursion, and the shipped examples shipped that default. maxDepth now defaults to 1; a numeric cap requires the provider's depthLimit capability (the mount fails loud and points to the explicit 'provider-managed' opt-out for out-of-process providers), and a child AT the cap loses the delegating tool from its own schema via the child toolFilter — prompt-face hiding on top of the execution-face depth check. Examples pin maxDepth explicitly. The ACP snapshot harness gains Scenario.childToolOmissions so a child session may legitimately omit declared delegation tools from its pinned header and prompt; affected subagent/workflow goldens are re-recorded.
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:echo # keyless mock-model REPL
pnpm run demo:repl # readline coding agent (needs DEEPSEEK_API_KEY)
pnpm run demo:tui # full-screen TUI coding agent (needs DEEPSEEK_API_KEY)
pnpm run demo:headless -- "task" # one-shot coding agent (needs DEEPSEEK_API_KEY)
pnpm run demo:cordis # self-referential 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.
