Master's #660 replaced dsh-subagent-subprocess with the dsh-subprocess capability seam (ctx.subprocess + scrubbedParentEnv, tree-scoped teardown) and moved subagent-acp onto it. Convergence for this branch's packages: - The shared out-of-process provider vocabulary this branch had grown in the deleted library (NO_START_CAPABILITIES, assertPositiveFinite, cwd resolution, settleRunResult, subprocessRunHandle) moves into the subagent seam package as out-of-process.ts — it enforces subagent-seam contracts, not process mechanics, and both out-of-process backends now import it from there (subagent-acp keeps master's shape otherwise). - subagent-sdk spawns THROUGH the SDK client (the subprocess README's documented exception for SDK-managed transports) and now applies the seam's scrubbedParentEnv() + explicit-env merge in place of the deleted buildChildEnv. - sdk-client inlines the EOF→SIGTERM→SIGKILL ladder as private helpers (it runs outside any harness context, so it cannot ride ctx.subprocess). - The child harness fixture gains the now-required dsh-subprocess-local entry for bash-local; the fixture cordis.yml keeps exercising the shipped provider default.
jsonrpc-agent
English | 中文
The unattended coding-agent composition for the Python SDK's bundled JSON-RPC runtime. It intentionally loads no terminal UI, console logger, approval surface, or user-interaction tool because stdout belongs to the SDK protocol and turns are driven by the SDK.
The model-facing tools are:
bash, foreground onlyread,write, andeditsubagent, using one foreground in-process spawn providertodo_write
The surrounding runtime also loads JSONL session persistence and automatic context compaction. maxTokensAsSuccess keeps a token-limited model turn as an accepted evaluation result while preserving its max-tokens reason.

|---|---|
DEEPSEEK_API_KEY |
Credential passed to the OpenAI-compatible host endpoint |
DEEPSEEK_BASE_URL |
Host endpoint used by dsh-llm-deepseek |
DSH_CWD |
Agent workspace for bash and filesystem tools |
DSH_MAX_TOKENS_AS_SUCCESS |
true (default) accepts token-limited results; false reports them as errors |
DSH_SESSION_ROOT |
JSONL trajectory directory |
DSH_SYSTEM_PROMPT |
Deployment-provided coding persona |
Pass the config path through the Python SDK's cordis option or DSH_CORDIS_CONFIG. The bundled executable already carries every plugin named by this file; the target machine does not need Node.js.
