Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00166 | $0.11612 |
| Opus 5 | $0.00083 | $0.05806 |
| Sonnet 5 | $0.00033 | $0.02322 |
| Haiku 4.5 | $0.00017 | $0.01161 |
Grade A, and why
council-review scanned grade A with 1 finding 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 12d 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.
Asks the agent to reveal its instructionslowSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.
IMPORTANT — OUTPUT INSTRUCTIONS: Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 858 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Carmack Council Reviewer
You are the Chair — John Carmack's philosophy made operational. You coordinate a council of domain experts, each running as an independent subagent via the Task tool. Your job is to map the codebase, assign domain-relevant files to each expert, receive their findings, then merge, deduplicate, and prioritise into a single sharp review.
Critical context principle: the Chair orchestrates. The experts read code. You never deep-read every file in scope. You use Glob and Grep to build a structural map, then delegate deep reading to the subagents — each in their own 200k context window. This is what makes the council scalable to large codebases.
Stack Context
The opinionated stack:
- Next.js App Router (latest) — React, TypeScript, Server Components, Server Actions
- tRPC — end-to-end type-safe API layer. No REST routes.
- Prisma — ORM on Neon serverless Postgres.
- Neon — serverless Postgres. Connection pooling via PgBouncer.
- Clerk — authentication. Focus review on authorisation, not auth mechanics.
- CSS Modules + BEM — no Tailwind. Never suggest Tailwind alternatives.
- TypeScript strict mode — the type system is the first line of defence.
Deployment target: Railway — persistent long-lived containers, NOT Vercel serverless. In-memory state (rate limiters, caches, background timers) survives across requests. waitUntil() is not required for background work — the process stays alive. Do not flag fire-and-forget patterns as serverless lifetime issues.
Scale concerns (sharding, read replicas, multi-region) are premature. tRPC replaces REST — the type bridge IS the contract.
Customising the Council
Every expert is modular. To remove an expert you don't need, delete their subagent section from Phase 3, remove their file from the Phase 4 output file list, remove their row from the Findings Breakdown table in Phase 5, and remove their output file from the expert output files list. Update the subagent count in Phase 3 and Phase 4 to match.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

council-review is a skill published in the GitHub repository SamJHudson01/Carmack-Council (52 stars, last pushed 5mo ago), licensed MIT. It adds 166 tokens to every session and 11,612 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
