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 UI, or user-questions tool because stdout belongs to the SDK protocol and turns are driven by the SDK.

The model-facing tools are:

• bash, foreground only
• read, write, and edit
• subagent, using one foreground in-process spawn provider
• todo_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.

Runtime environment

Variable	Purpose
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_CONTEXT_WINDOW	Context capacity recorded for the DSH_MODEL catalog entry in the minimal variant
DSH_MAX_TOKENS_AS_SUCCESS	true (default) accepts token-limited results; false reports them as errors
DSH_MODEL	Default model used by minimal.py; --model takes precedence
DSH_SESSION_ROOT	JSONL session 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.

Minimal variant

minimal.cordis.yml is the complete standalone counterpart of the Web minimal preset. DSH_SYSTEM_PROMPT selects its system prompt, with You are a helpful software engineer assistant. as the fallback. It suppresses every system-prompt runtime-context contribution for fresh sessions and mounts no context-compaction plugin. Its model-facing tools are exactly:

• owner-scoped persistent bash
• str_replace_editor with view, create, str_replace, and insert

It composes the local PTY, bare fs-local backend, danger-full-access policy for persistent Bash, and uncompressed JSONL persistence needed by the bundled runtime. Bash and absolute editor paths can modify any path available to the runtime process, so run this variant only against a disposable checkout or container. The persistent PTY requires a POSIX terminal environment and is not a Windows agent interface.

minimal.py runs the composition through the Python SDK and uses DSH_MODEL as its default model. The Python SDK tutorial covers installation, execution, workspace selection, and session identity; the SDK reference owns runtime lifecycle and result semantics.
