Oh My Pi Delegate

You are the orchestrator. Delegate a bounded coding task to a separate implementer - Oh My Pi (omp) - then review what it produced and land it yourself. You write the brief and own the judgment; the implementer makes changes in its own session; you verify and commit.

The loop needs only a shell command and file access, so any comparable orchestrator can drive it.

The binary is omp, not pi

Oh My Pi is a fork of Pi. This skill drives omp (@oh-my-pi/pi-coding-agent). The original Pi CLI is a different binary (pi) with a different skill (pi-delegate). If omp is missing but pi is installed, you have Pi, not Oh My Pi.

When NOT to use this

• The task is small enough to do inline; delegation overhead is not worth it.
• The omp CLI is not installed or authenticated.
• The user asked for the original Pi CLI (pi) — use pi-delegate.
• You need a sandboxed implementer. Oh My Pi has no sandbox. --read-only restricts the tool surface; a write-capable run executes without prompts (--yolo).

Prerequisites (check once)

1. Install omp with bun install -g @oh-my-pi/pi-coding-agent (or the install path from https://omp.sh).
2. Authenticate: /login inside omp for a subscription provider, or an API-key environment variable for an API-key provider. Credentials live under ~/.omp/.
3. Confirm omp --version succeeds.
4. Work in, or point --cd at, the target git repository.

Choose the model (optional)

Omit --model (and --provider) to use omp's configured default for this project / profile. The catalog is this install's authenticated providers — not a fixed list in this skill.

To pick another model:

1. List what this install can actually run. Do not pass omp --list-models — that flag is gone and omp treats it as an unknown flag (exit 2). Use the models subcommand:
   • omp models — every available model, grouped by provider
   • omp models --json — the same catalog, machine-readable
   • omp models find <substring> — filter by provider, id, or name (example: omp models find sonnet)
   • omp models <provider> — one provider's models
2. Pass that id to the relay. --model <pattern> is omp's own --model: a fuzzy match against the catalog (provider/id, a bare id, or a unique substring). --provider <name> pins the provider when the pattern is ambiguous.
3. The relay forwards only letters, digits, and . _ : / -. Glob patterns with * are rejected.

--thinking <level> is a separate reasoning dial, not a model id. Allowed values: off, auto, minimal, low, medium, high, xhigh, max. The relay rejects anything else (including inherit) before dispatch — omp would otherwise warn and ignore a bad value.

A fleet lane (--lane) can set provider, model, and effort. Lane effort becomes --thinking; an explicit --thinking / --model / --provider flag wins over the lane.

The relay does not forward --api-key, --smol, --slow, or --plan. Those stay omp's own CLI.

The loop

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

1. Write the brief

Oh My Pi sees only the text you send plus what it can inspect in the workspace - no chat history or shared context. Include the goal, current state, what to change, what to leave untouched, the project's actual gates, and a report contract. Tell omp not to commit. Keep one task per brief. omp auto-loads AGENTS.md/CLAUDE.md context files from the workspace and its parents, so repo instructions reach it without inlining. See references/writing-the-brief.md.

2. Dispatch

For Codex orchestration of background work, install and configure the separate codex-background support utility first. If its MCP tools or registry are missing, stop and report the setup requirement; do not silently fall back to model-driven polling. Then invoke its registered delegate_run MCP tool once in place of the shell example below. Follow that skill for structured common arguments, unchanged provider flags and reattachment by runId. Keep the request pending until completion, then continue this skill's review and landing steps. Other orchestrators keep the shell workflow below.

Use the bundled relay. It pipes the brief to omp --mode json on stdin, captures the JSON event stream, and writes result.json. (<skill-dir> is the installed folder containing this SKILL.md.)

node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# list models first:                       omp models   (or: omp models --json)
# choose a model:                          add --model <id from omp models>
# choose a provider:                       add --provider <name>
# set thinking level:                      add --thinking high
# read-only run (review/diagnosis):        add --read-only
# trust project .omp resources:            add --approve
# resume the most recent session:          add --resume-last  (delta brief only)
# resume a specific session:               add --session <id> (delta brief only)
# hard time limit (watchdog):              add --timeout 2h  (the 30m default suits short runs; implementation briefs routinely need 1-2h)
# see all options:                         node .../relay.mjs --help

The child process's cwd pins the workspace. The relay writes artifacts under the system temp dir by default and never commits. See references/dispatch-and-poll.md.

3. Wait for completion

Codex using codex-background keeps the original MCP request pending: no model-driven sleep, status or log polling. Use delegate_wait only to reattach after an interrupted request.

The relay blocks until omp finishes. Run it with the orchestrator's background-command facility, or background it in the shell and poll for result.json. A pre-run usage error exits 2 and writes no result; a missing omp exits 127 and writes status: "omp_unavailable".

Trust process state and the working tree over a progress display. Completion means the process exited and result.json exists. omp'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

Treat omp's final message and gate claims as claims:

• Re-run the project's gates yourself.
• Read the diff against the brief, starting with touchedFiles.
• Run relevant guard skills if installed.
• Round-trip migrations and grep for dangling references after removals or renames.

See references/review-and-land.md.

5. Land it

The implementer edits the working tree; the orchestrator commits. Commit only after the gates pass and the diff holds. If rework is needed, send a delta brief with --resume-last or --session <id>, then review again.

Autonomy and permissions

Oh My Pi has no sandbox. Print mode has no approval UI, so a write-capable relay run always passes --yolo (tools.approvalMode: yolo) — otherwise a user's always-ask or write config would stall until the watchdog. The other controls are:

1. --read-only restricts omp's callable tools to --tools read,grep,glob. It does not pass --yolo. Installed extension code still runs with the user's host permissions if project resources are trusted.
2. The relay passes --no-extensions --no-skills --no-rules by default, so project .omp extensions, skills, and rules stay undiscovered. --approve is the explicit opt-in for a repository the user trusts.
3. touchedFiles and the diff are the record of what changed. Inspect them after every run.

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. Two limits remain: surface, don't absorb (report omp's design decisions, defensible-but-unasked turns, and non-blocking nitpicks) and stop for scope changes (if correct completion needs going beyond the brief, ask instead of expanding the mandate). See references/review-and-land.md.
