commandcode-delegate skill

Command Code Delegate

You are the orchestrator. This skill lets you hand a bounded coding task to a separate implementer — the Command Code CLI (cmd) — then review what it produced and land it yourself. You write the brief and own the judgment; Command Code does the typing in your working tree; you verify and commit.

Nothing here is specific to one orchestrating agent. The loop needs only the ability to run a shell command and read a file, so it works the same whether you are Claude Code, OpenCode with a selected model, or any comparable agent. (It is designed for and run on Claude Code; treat other orchestrators as designed-for, not yet proven.)

When NOT to use this

• The task is small enough to just do inline — delegation overhead is not worth it.
• The cmd CLI is not installed or not authenticated (run cmd login).
• You want to write the code yourself, or you only need a review (Command Code has its own /review).
• You are on native Windows and cmdc --version does not work. Upstream recommends WSL for stable Windows use.

Read this before the first dispatch: the autonomy model

Command Code's headless mode has exactly two states, with nothing in between:

refused by the CLI's permission layer, and headless mode has no prompt to grant them mid-run. This is the relay's --read-only.

• Default (-p with no --yolo): read, grep, and glob work. Every write, edit, and shell call is

can reach. There is no filesystem sandbox and no path restriction. This is what an implementation run needs, so the relay passes it by default.

• --yolo (alias --dangerously-skip-permissions): every tool is allowed, anywhere the process

--permission-mode auto-accept and --tools-all do not lift the headless write gate. Direct CLI probes refused write, edit, and shell with both. So an implementation run through Command Code is a full-trust run: scope it with a tight brief and a clean working tree, not with a sandbox. The brief is guidance, and a git worktree isolates a checkout without containing the process. If writes outside the target tree are unacceptable, use an OS-enforced sandbox such as codex-delegate or run this one inside a container.

Prerequisites (check once)

run cmd login.

1. cmd --version succeeds and cmd status reports authenticated. If not, install Command Code and

Windows, use cmdc --version; cmd is the system shell. The relay uses cmdc there and launches its npm .cmd shim through cmd.exe. COMMANDCODE_BIN remains an absolute-path override and must never point to the system command interpreter. The relay records the version it ran in result.json, so a wrong binary is visible after the fact.

1. Confirm the CLI on PATH. On macOS/Linux, command -v cmd shows the active cmd. On native

dispatch — a full-trust run is much easier to review against a clean baseline.

1. You are in (or will point --cd at) the target git repository, and its tree is clean before you

The loop

Run these five steps per task. Steps 1, 4, and 5 are your judgment; 2 and 3 are mechanical.

1. Write the brief

Command Code sees only the text you send — no repo memory, no chat history, no shared context (beyond the repo's own AGENTS.md, which it reads automatically). Everything the task needs goes in the brief: the goal, the current state, what to change, what to leave untouched, the project's actual gate commands (discover them from the repo's AGENTS.md/CLAUDE.md/Makefile — do not assume), and a report contract. Tell it that it will not commit (you will). Keep one task per brief. Full guidance and a template: references/writing-the-brief.md.

2. Dispatch

Send the brief to Command Code with the bundled helper. It wraps cmd -p, captures the run, and writes a structured result.json — so your only job is "run a command, read a file." ( below is this skill's installed directory — the folder containing this SKILL.md, i.e. the directory you loaded the skill from. Claude Code prints it as "Base directory for this skill" when the skill loads; on other orchestrators use that same directory — if unsure where it landed, run find ~ -name relay.mjs -path 'commandcode-delegate' and substitute the directory above it.)

node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# read-only (review/diagnosis, no edits):   add --read-only
# continue the exact session:               add --session <sessionId>  (from result.json; send only the delta brief)
# fallback when no session id is available: add --continue-last
# hard time limit (watchdog):               add --timeout 2h  (default: off; implementation runs routinely need 1-2h)
# see all options:                          node .../relay.mjs --help

The helper defaults to a write-capable (--yolo) run, which intentionally edits the target repository. Its temp directory keeps only relay artifacts out of that repository. The relay never commits — see step 5. Mechanics, flags, and the result.json shape: references/dispatch-and-poll.md.

3. Wait for completion

The helper blocks until Command Code finishes, so back it with whatever your orchestrator offers and resume when it returns:

the result file — … & in bash/zsh, or your shell's equivalent. The run is done when result.json exists with a status. (A pre-run usage error — bad args or an empty brief — instead exits with code 2 and a stderr message and writes no result file, so check the exit code too. A missing cmd binary exits 127 but does write a result.json with status commandcode_unavailable.)

• Claude Code: run the Bash call with runinbackground: true; you are notified on completion.
• Plain shell / other agents: run it in the foreground for short tasks, or background it and poll

Do not trust progress trackers over reality: a run is finished when result.json is written and the process has exited. Read the working tree, not a status line. The implementer's full report is the finalMessage field in result.json (also printed in full on stdout between the report markers).

4. Review — do not trust the self-report

result.json includes Command Code's own summary and gate claims. Re-verify, don't accept:

"gates passed" on faith.

• Re-run the project's gates yourself (the test/lint/build commands from step 1). Never take

nothing less? touchedFiles in the result is your starting point — and because the run was full-trust, check for edits outside the paths the brief named, not just inside them.

• Read the diff against the brief: did it do what was asked, nothing more (scope creep) and

test-guard, etc. from guard-skills) — this skill produces the work; those skills judge it.

• Run the relevant guard skills on the diff if you have them installed (clean-code-guard,

• For schema/migration changes, round-trip them; for removals, grep for dangling references.

Full checklist: references/review-and-land.md.

5. Land it

The relay never commits, but it cannot stop Command Code under --yolo from writing .git. The brief forbids implementer commits, and the reviewer compares HEAD with the recorded pre-dispatch baseline before landing anything. The orchestrator commits. Only after the gates pass and the diff holds:

(use --continue-last only when no session id is available), and review again.

• Commit the verified work yourself, with a clear message.
• If it needs changes, send a delta brief with --session from the prior result.json

Read-only second opinions

The relay doubles as a clean way to get an adversarial second opinion: dispatch --read-only with a brief that lists the agreed points, then each contested point with both positions, and ask Command Code to defend or concede each — deliverable in its final message, touching no files. The read-only guarantee here is the CLI's own permission layer rather than an OS sandbox, so the relay also checks it after the fact: readOnlyViolation: false means the Git-visible detector saw no change (ignored or outside-repository paths are not covered); true means it saw one; null means git could not tell.

Authorization model

Delegation is something the human opts into. Once they have ("run this queue", "proceed"), committing verified, gate-passing work is the agreed contract — that is the whole point. Two limits on that mandate: surface, don't absorb (report Command Code's design decisions, defensible-but-unasked turns, and non-blocking nitpicks rather than silently keeping them) and stop for scope changes (if correct completion needs going beyond the brief, ask — don't expand the mandate yourself). The full treatment is in references/review-and-land.md.
