council-review

council-review is a skill for Claude Code from joymin5655/Agent. It costs 143 tokens per session (3,217 once invoked), scanned A, original, MIT.

A code-review process that asks several different AI systems for independent opinions on the same code change, then combines their findings. It can show disagreements and identify which sources support each finding.

In plain words
What is it for?
Use it to review a code diff for implementation correctness, architecture, and consistency, with optional additional advisory reviewers.
Why use it?
One reviewer may miss a problem or make a false claim. Comparing independent reviews helps separate issues supported by the code from issues that need further checking.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

council-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Goal

One diff, several independent reviewers, one synthesized report. Different models fail differently — a finding two vendors reach independently outranks a finding one vendor reaches confidently, and a synthesizer that answers to the actual code (not to the reviewers) drops what was hallucinated.

Lanes

Lane Vendor Lens Dispatch Participates in verdict
code-reviewer agent anthropic its own agent charter Agent tool (model pin: sonnet, unchanged) yes
second-opinion-review openai (codex) implementation correctness core/infra/call-worker.sh yes
third-opinion-review google (gemini, via antigravity) architecture & consistency core/infra/call-worker.sh yes (when lane enabled)
advisor-third (--with-grok) xai (grok) unscoped (free perspective) core/infra/call-worker.sh no — advisory only
advisor-free (--with-free) openrouter (model vendor pinned in adapters/openrouter/*.template — see core/infra/backends.json's honesty comment) unscoped (free perspective) core/infra/call-worker.sh no — advisory only

Lane SSOT is core/infra/backends.json. A disabled lane (e.g. one whose CLI or preflight is missing) refuses loudly at dispatch; report it as absent — never substitute another vendor for it (a fallback that shares a seated vendor would fake the independence signal).

The grok lane runs on the free tier by design (decided 2026-08-19): when its quota is exhausted mid-review the lane surfaces status: rate-limited and the council fails open — the review proceeds without the advisory, the lane status line says "rate-limited, retry later", and no upgrade prompt is put to the user. The openrouter free lane carries the same fail-open contract on its own 429s (adapters/openrouter/README.md), but its cost is retention, not quota — see step 2.

Steps

0.5. Mark council-active before dispatching the Claude lane

Before this skill's own code-reviewer Agent dispatch (step 3), set the council-active flag through the gate's own CLI — never write a flag file directly. The escape hatch now lives OUTSIDE this repo (keyed to the project root) and its content must be the CURRENT diff's hash, which only the CLI can produce:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
