## Description

Review a change in rounds with GPT 6.1 Sol as a separate reviewer until it approves or the budget runs out. Use when the user says "sol loop" or asks for a Sol review loop before shipping.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# sol-loop

GPT 6.1 Sol reviews your change in rounds. Make the smallest changes that answer it, avoid scope creep, and push back when it is wrong.

## Budget

- 3 rounds. Round 1 is full; later rounds check only changed code and open findings.
- 5 only if the user asks, or for security, permissions, auth, data loss, or state/concurrency while a blocker or should stays open with evidence.
- Stop early if a round returns only nits. Declined nits and comment, doc, or format-only fixes need no new round.
- One reviewer only. Sol must not start subagents or reviewers.
- Keep a ledger: id, severity, outcome, usage if returned. Never guess usage.

## 1. Scope

Run `git status --short`. Never stash, discard, or include unrelated changes; if they don't separate cleanly by path, stop and ask.

After `git fetch origin`, base is `git merge-base HEAD origin/<PR base or default branch>`. For a PR, `HEAD` must be the PR head or ahead only by this change. No remote: a base the user names, or `HEAD` for uncommitted changes only. The change is base to working tree, untracked files included; use the same diff every round.

State intent and out-of-scope in 1-2 sentences. Run the covering checks (`swift build`, `script/test_quiet.sh --filter <Suite>`); never send code the change breaks. Note missing or already-failing checks in the brief.

## 2. Start Sol

The reviewer is GPT 6.1 Sol, unless the user names another Sol version. Reach it the way your harness allows:

- Capy: a subagent or thread on model `openai/gpt-6.1-sol`; keep its path or code for later rounds.
- Cursor: a background agent or new chat with GPT 6.1 Sol selected.
- Claude Code and other harnesses without GPT models: Codex CLI, `codex exec -m gpt-6.1-sol -` with the brief on stdin (read-only sandbox by default). Note the session id it prints; `codex exec resume <SESSION_ID>` continues it.
- Anything else: give the user the brief to run in a Sol session and wait for the reply.
