review-anvil — Iterative Multi-Agent Fix/Review Loop

Wrap a code change in requested rounds of parallel reviewer subagents + orchestrator-applied fixes. Each round = (parallel review by M agents, each with a distinct lens) → (you synthesize and verify findings) → (you apply fixes, run the build/test gate, commit) → next round. In productive per_fix runs, the orchestrator may continue adaptively after the requested rounds until convergence or max_rounds.

Preset skills

This is the engine. Three preset skills in the same plugin pin common configurations; each is a separate skills/<name>/SKILL.md whose description triggers activation cross-agent.

Preset	Pins	Intent
`review-anvil` (engine)	nothing	Default fix/commit loop, or any custom param combination.
`review-anvil-readonly`	`commit_mode=none`; default `rounds=1`	Read-only review — no edits, no commits.
`review-anvil-pr [<locator>]`	`commit_mode=none`, `target=<locator>`, `report_path=<file>`, trusted `run_ordinal=<observed>`	Review a GitHub PR and post the report back as a PR comment (orchestrates `scripts/pr-helper.sh`). Locator auto-detected from the current branch when omitted.
`review-anvil-improve-pr [<locator>]`	`commit_mode=per_fix`, `target=<base>...HEAD`, `report_path=<file>`, trusted `run_ordinal=<observed>`	Improve a checked-out PR: fix commits across requested rounds plus any adaptive continuation, then push. Targets the branch (not a PR locator), deliberately routing around the PR-target/per_fix rule below.
