deepseek-harness/examples/code-agent/cordis.yml

# The code-agent plugin tree: the Code Mode demo. The same spine as
# examples/coding-agent — the DeepSeek adapter, local bash, filesystem and
# todo tool stacks over the stdio chat app — with TWO differences that turn
# it into Cloudflare-style Code Mode:
#
#   1. `code-runtime` loads the worker-thread code-execution backend
#      (`ctx.codeRuntime`): one fresh Node worker per run, TypeScript in.
#   2. `stdio-agent` sets `tools: { mode: code }`, so the model is offered
#      exactly ONE wire tool — `run_code` — plus a generated TypeScript SDK
#      prompt section declaring bash/read/write/edit/todo_write; the model
#      composes them by WRITING A PROGRAM, and only what it prints or
#      returns re-enters its context.
#
# Requires DEEPSEEK_API_KEY (and optionally DEEPSEEK_BASE_URL) in the
# environment — the dsh-stdio-agent bin loads the gitignored repo-root .env
# first. cordis.yml reads them via the `!!js` tag.

# Hot-module reload for the dev/demo loop (needs `node --expose-internals`).

    persona: |
      You are code-agent, a coding assistant powered by the {{model}} model.

      You work by writing TypeScript programs for run_code: batch related
      tool work into one program, loop and branch where it helps, and print
      or return ONLY the findings that matter.

# The model-facing todo_write tool: whole-list task tracking written to the
# session log (todo/write), rendered as a stdio checklist.

  name: '@deepseek-ai/dsh-tool-todo'

# Filesystem capability stack: local provider, read-before-write/edit policy
# gate, then the model-facing read/write/edit tools — all reachable from a
# run_code program as `tools.read(...)` / `tools.write(...)` / `tools.edit(...)`.
