# `llm-council` — external-tools review layer ## Overview Wraps `pr-council-review` (unchanged) and adds a layer of external CLI coding agents (`codex`, plus Antigravity — the `agy` harness) as additional independent reviewers, then folds their verdicts into the same synthesis. Internal Claude subagents are independent per-dimension but share one model family's blind spots — a phrasing choice, a Windows-vs-POSIX nuance, or a syntax error that reads fine to one Claude reviewer reads fine to all of them. A different model family catches a different error distribution. Confirmed live: on one review, external tools caught 6 real, distinct issues (a wording-accuracy bug, a wrong test count, a Windows-only test-triviality nuance, a test-isolation gap, a missing test, a malformed markdown fence) that 12 internal Claude-subagent dispatches (6 dimensions × 2 rounds) had all missed. ## When to Use - Any `pr-council-review` run (PR# mode or branch mode) where the artifact is high-stakes enough to want a second, differently-biased opinion before calling it GREEN. - Not needed for a quick spot-check or draft iteration — use `/review` (single-agent) for that; `pr-council-review` alone for a normal-stakes PR. ## Quick Reference — Tiers | Tier | Internal (pr-council-review) | External tools | |---|---|---| | `small` (default) | ✅ full dimension council | none — identical to running `pr-council-review` directly | | `medium` | ✅ | `codex` | | `high` | ✅ | `codex` + Antigravity (`agy`) | ...
