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 | $0.01595 | $0.01595 |
| Opus 5.5 | $0.00638 | $0.00638 |
| Sonnet 5.5 | $0.00319 | $0.00319 |
| Haiku 4.5 | $0.00160 | $0.00160 |
Grade D, and why
the-council CLAUDE.md scanned grade D with 2 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 1mo 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
Invocation creates `.council-tmp/council_<mode>_YYYYMMDD_HHMMSS/` (where `<mode>` is `full`, `codex`, or `gemini` depending on which advisors ran) in the working directory, containing `prompt_final.txt`, `review_request. This is a copy
97% identical to the-council AGENTS.md — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
The Council is a Claude Code Skill plugin that convenes OpenAI Codex (codex CLI) and Google Gemini (agy CLI, Google's Antigravity client running Gemini 3.5 Flash by default) as an advisory board. Both run in parallel as effectively read-only consultants, returning independent analyses that Claude synthesizes into unified recommendations.
This is not a Node/TypeScript application — it's a pure Bash + Markdown skill with no build system, package manager, or test framework.
Architecture
skills/the-council/
├── SKILL.md # Operational guide (skill definition + workflow)
├── references/prompt-templates.md # 4 prompt templates (review, architecture, debug, general)
└── scripts/
├── council_preflight.sh # Detects available CLIs + auth status (cached 2h)
├── council_sync.sh # Copies CLAUDE.md → AGENTS.md (Codex only)
└── council_invoke.sh # Parallel CLI invocation: timeouts, OS sandbox, snapshot safety net, response validation
Execution flow: Preflight → Sync context → Compose prompt from template → Invoke advisors in parallel → Synthesize responses (consensus/divergence/recommendation) → Generalize learnings into CLAUDE.md/AGENTS.md.
Operating modes are determined by preflight: Full Council (both CLIs), Codex-only, Gemini-only, or abort (neither available).
Key Design Decisions
- Read-only enforcement (1.3.0+): Both advisors run with OS-level deny-write sandboxes on macOS. Codex uses its built-in
--sandbox read-only. Gemini (agy) is wrapped insandbox-execwith a deny-write profile atskills/the-council/scripts/council_sandbox.sb; writes are allowed only to~/.gemini/, the per-invocation.council-tmp/<...>/dir, system temp, and agy-specific~/Library/Caches/subdirs. On non-macOS, the script refuses to run agy unless--allow-unsandboxed-geminiis passed. - Diff safety net (1.3.0+): pre/post-invocation snapshot of
$WORK_DIR(git: HEAD + status with--ignored=traditional+ sha256 of tracked + untracked + gitignored files; non-git: find + sha256). Snapshot excludes.council-tmp/(response files) and.antigravitycli/(agy's housekeeping dir). Any other change fails the invocation with exit 2 and a[COUNCIL_SAFETY_NET]banner. See SKILL.md for the historical 1.2.x ghost-write incident this replaces. - Gemini invocation (1.4.0): Gemini reviews the INLINED prompt only — no project
--add-dir, no repo exploration. The composed prompt is written into the per-invocation.council-tmp/<run>/dir, which becomes the advisor's only workspace. The backend is resolved at runtime:geminiCLI (single-shot, stdin, JSON envelope) when a paidGEMINI_API_KEY/GOOGLE_API_KEYis set andgeminiis on PATH, elseagy(pty-wrapped viascript, sandboxed). The oldmaxSessionTurnssettings injection was a verified no-op and is gone —~/.gemini/antigravity-cli/settings.jsonis never touched. - Prompt sanitization:
jsr:import strings are redacted from the Gemini prompt before invocation to avoid spurious safety/policy blocks fromagy. - Empty-response retry: If
agyexits 0 with no stdout and no stderr, the invocation is retried once before being reported as failed. - Response validation (1.4.0): an advisor fails only on empty output, a script-written
[COUNCIL-ADVISOR-FAILURE]placeholder, a nonzero exit with no verdict line, a refusal, or non-engagement (a short verdict-less reply to a large prompt). The old response-body word-grep (policy/blocked/quota/rate limit) is gone — it false-failed substantive reviews; stderr noise now demotes to an advisory*_warnings.log, not a failure. - Parallel execution: Both advisors run as background processes with configurable timeout (
COUNCIL_TIMEOUT, default 600s). - NVM compatibility:
council_invoke.shloads NVM environment to find globally-installed CLI tools. - macOS support: Uses
gtimeout(from coreutils) when available, falls back totimeoutor no timeout. - Graceful degradation: Works with one advisor if the other is unavailable; shows install help if neither exists.
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.

the-council CLAUDE.md is an instructions file published in the GitHub repository DantesPeak85/the-council (3 stars, last pushed 15d ago), licensed MIT. It adds 1,595 tokens to every session, about $0.0064 per session on Opus 5.5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). It is 97% identical to the-council AGENTS.md, differing in 8 lines, and is treated as a copy.
