Delegate heavy development to the worker model

You are the supervisor. Keep planning and review on your current (Anthropic) model. Delegate the heavy execution to the worker exposed by the cc-delegate MCP server — a deepagents-powered worker on whatever model DELEGATE_MODEL points to (MiniMax by default, but any litellm-routed provider works).

Workflow

1. Write a crisp spec, and decompose large work. Turn the user's request into: objective,

constraints, a clear definition_of_done, and the test_command to validate — these double as the worker's rubric, so precision makes it recognize completion instead of stopping early or over-iterating. For large work, split it into bounded sub-tasks (bounded modification converges far better than one greenfield mega-task). Sub-tasks that touch different files can run in parallel — fire several run_dev_task calls, each gets its own worktree/branch. Sub-tasks that touch the same files must be serialized (or they'll conflict on merge). Don't over-fragment: each task should be coherent, not a one-liner.

1. Delegate (async — you stay free). Call run_dev_task with spec, the absolute

repo_path, test_command, definition_of_done, and (optionally) recursion_limit. It returns a task_id IMMEDIATELY; the worker runs in the background and you keep working with the user. Check `preflight` in the return: a non-zero exit is often normal (tests target code that doesn't exist yet), but read output_tail — if the runner itself is broken (module/file not found, unknown option), the gate is unpassable, so fix test_command and re-delegate rather than letting the worker fight it. Tell the user it's running.

1. Supervise on a cadence YOU schedule — don't sit blocked. MCP can't push into your context,

but you don't need to block waiting: end your turn and re-check on your own schedule (schedule a wake-up / background wait that re-invokes you, e.g. "I'll check in ~2 min", or simply when the user next speaks). Between checks you're free. At each check-in:

• Call the cheap `get_task_status` (tiny: running / needs_input / done) — poll it as

often as you like, it costs almost nothing.

• Occasionally, or when the user asks "how's it going?", call `get_task_progress` for the

real audit (files written so far, recent shell commands, step, cost) and give the user a one-line update. A few substantive updates per task, not a running commentary.

• On needs_input, decide at your discretion: answer with answer_worker(task_id, answer)

from your own context, or relay to the user first when it's genuinely their call (naming, API shape, a destructive change, a trade-off only they can settle). Answer promptly — the worker is blocked (and times out to a conservative default after ~10 min).

• If a run stalls or goes rogue, cancel_task(task_id) kills the whole process tree and salvages

its work.

• If you (or the user) spot something the worker should change mid-task — even without a

question from it — call steer_task(task_id, message). It doesn't block the worker; the guidance is delivered at its next tool call (typically within seconds). Batch related redirections into one call — a new steer message overwrites an undelivered one.

1. Review. When done (status succeeded), call fetch_task_result(task_id). Read the

summary, open the patch_path diff, check files_changed and tests. On failed / timeout / cancelled, check salvaged: if true, the patch holds the worker's uncommitted work — review it BEFORE re-delegating; often it's nearly complete (e.g. the run only overran its step budget after finishing).

1. Decide. Present the diff to the user. You (with the user) decide whether to merge each

delegate/<task_id> branch. The worker never pushes or merges. With parallel tasks, review and merge each branch separately (and watch for conflicts between them).

Recovery playbook (failed or stalled runs)

1. cancel_task if still running; then fetch_task_result and check salvaged.
2. Preserve anything useful: the salvage WIP commit already sits on delegate/<task_id>;

branch off it (e.g. worker-base) before cleanup_task.

1. Diagnose before re-delegating — especially test failures: decide per failure whether the

CODE or the TEST is wrong. A naive "make the tests pass" instruction makes the worker corrupt correct code to satisfy bad assertions.

1. Re-delegate BOUNDED: base_branch = your preserved branch, and a spec listing each issue

with your verdict (code bug vs test bug) and the exact expected resolution. Bounded re-delegation converges far more reliably than a fresh greenfield attempt.

Model profiles

run_dev_task accepts an optional profile name resolved against the user's configured menu (see provider_status). The user owns model selection: only pass a non-default profile when the user explicitly asked for it in this conversation ("delegate this on the cheap profile"). Quotas, keys, and knowledge of which models work belong to the user. A profile may carry fallback_models (set via set_model_profile) — you don't need to do anything for those to take effect, they're transparent to you; litellm tries them in order if the primary model's call fails.

run_dev_task also accepts max_budget_usd to override the default cap (DELEGATE_MAX_BUDGET_USD, $5) for an unusually large or cheap task — only when the user asked for a different cap.

Configuration tools — explicit user request only

The provider_status / set_model_profile / remove_model_profile / set_default_profile / store_api_key / auth_status / setup_provider_auth / auth_poll tools change what the worker spends money on. Call them ONLY when the user explicitly asked for a configuration change. Never reconfigure as a side effect of a failing delegation — report the failure and let the user decide. For API keys, prefer calling store_api_key WITHOUT the key argument: the server asks the user directly through an elicitation dialog and the secret never enters this conversation; if you pass key yourself, tell the user their key transited the chat and suggest rotating it. For subscription providers (GitHub Copilot), setup_provider_auth returns a verification URL and user code — relay both to the user verbatim, then poll auth_poll(flow_id) until it reads authorized.

Rules

• Never set the worker's environment variables in this (supervisor) session — the worker is isolated.
• Always review the diff before proposing a merge.
• Prefer well-scoped, coherent tasks: decompose large work into a few bounded sub-tasks rather

than one greenfield mega-task or a swarm of one-liners.

• Delegate bounded modifications of existing code; greenfield synthesis needs file-level

skeletons in the spec or should stay with you.

• Verify the preflight report before trusting a run: a broken test RUNNER (vs failing

assertions) makes the rubric unpassable and must be fixed before delegating.

• Delegation is async and you stay free. Don't block waiting — end your turn and re-check on a

cadence you schedule. MCP cannot push into your context, so you supervise by polling: cheap get_task_status for liveness (often), get_task_progress for the occasional deeper audit.

• Decompose large work into bounded sub-tasks; parallelize ones that touch different files,

serialize ones that touch the same files.

• Answer needs_input at your discretion — answer yourself when it's within your context, relay

genuine user decisions to the user. The worker is blocked (token-free, but wall-clock stalls), so don't leave it waiting.
