Keep DeepSeekHarness.run() reusable, but make ownership of its lazy runtime process explicit. Document the context-manager/close contract and update every construction example to use a context manager so repeated runs remain valid without encouraging leaked subprocesses. Contain notification predicate failures at the subscription boundary. Remove only the subscriber whose callback raised, deliver that exception through its queue, and continue dispatching to healthy subscribers so arbitrary callback code cannot terminate the shared reader thread or strand later requests. Enforce one in-flight prompt per server session with an atomic activePrompt guard. Route overlap through the existing -32603 handler-error response and clear the guard in finally, preserving parallel prompts across sessions and sequential reuse without changing JSON-RPC request or notification shapes. Use StringDecoder for line framing so a UTF-8 code point split across Buffer chunks is not corrupted. Add a queued-write flush barrier, and make memoized shutdown await it before disposal and exit while retaining exactly-once cleanup when shutdown calls race or flushing fails. Cover callback isolation, same-session exclusion, cross-session concurrency, split multibyte input, delayed writes, racing shutdown, and flush failure with deterministic tests. |

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.
