The dsh-tools half of the Code Mode RFC (its fourth, final change): the registry gains its first config — mode: native | code | both — and OWNS how its tools reach the model. 'code' contributes exactly one wire tool, run_code, plus a lazy tools:sdk prompt section declaring every other tool as a generated TypeScript API (jsonSchemaToTs: total over the defineTool subset, unknown degradation, lexicographic byte-identical rendering); 'both' ships both representations; 'native' is byte-for-byte the old behavior. Non-native modes fail every assembly loudly without a typescript-language ctx.codeRuntime. run_code's dispatch bridge: JSON-normalizes each binding argument before dispatch (what dispatches is what the tool/code-dispatch event logs — the append can never fail on payload shape; BigInt/circulars reject that one call), serializes all program tool calls through a per-run queue (even Promise.all — no concurrency-safety metadata yet), routes every sub-call through tools/pre-execute → tools/post-execute (a deny rejects the program-side promise), drops sub-call additionalContext (no safe outlet mid-run; pinned), owns a run-scoped abort that follows the outer signal in and fires on settlement (in-flight sub-dispatch aborted, queued abandoned, queue drained before returning), and converts a failed run into CodeRunFailedError → a structured isError carrying kind + captured logs. tool/code-dispatch joins SessionEventMap by declaration merging (log-only; deriveMessages ignores it). The composed surface: the tools config forwards through agent-core and both app packages; examples/code-agent + demo:code run the worker runtime under mode code (keyless boot smoke + a with-key e2e proving the collapsed [run_code] header, the dispatch events, and the file the program wrote); two new snapshot scenarios (code-mode-turn, both-mode-turn) record the SDK section, collapsed header, dispatch events, and result card — each its own header-pinning class (the harness gains per-scenario config overlays and per-class pins). Catalogs, graphs, cookbook, hooks-bridge notes, and the RFC (moved to implemented/, restructured to decision-era headings) updated in the same change.
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.
