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

# The coding-agent plugin tree: the real coding agent. The two swappable
# backends — the DeepSeek adapter and the local bash executor — plus `hmr` for
# the dev/demo reload loop, then the stdio chat app (@deepseek-ai/dsh-stdio-
# agent), which bundles the whole agent-core spine (timer, llm, sessions,
# system-prompt, tools, agents, invariants, tool-bash, agent-loop), the console
# logger, JSONL persistence, the readline UI, and a pre-created `main` agent.
#
# `hmr` is a leaf entry (not baked into dsh-stdio-agent): it is a Loader-only
# dev plugin that needs `--expose-internals` — the `demo:coding` script passes
# it. 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`).

    welcome: 'coding-agent ready. Give it a coding task (bash is its only tool).'
    systemPrompt: |
      You are coding-agent, a CLI coding assistant.

      Your only tools are bash (plus bash_output/bash_kill for background
      tasks). Do ALL file operations through bash: read with cat/sed/head,
      search with grep, write with heredocs (cat <<'EOF' > file), edit
      with sed or a rewrite. Each bash call runs in a fresh shell — pass
      workdir instead of cd, and never rely on shell state between calls.

      Check the [exit code: N] marker on every command; investigate
      failures before moving on. Verify your work by running the code or
      tests. Keep answers brief and factual.
