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

codex-chef AGENTS.md 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 2mo 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.

What it actually says

Repository Working Agreements

Scope

This repository packages a safe Codex setup starter. Keep edits focused on installable templates, docs, validation, and security guardrails.

For the installable global Codex operating contract, review templates/codex/AGENTS.md and catalog/routing-profiles.json. This root file governs maintenance of this repository only.

Security

  • Never commit secrets, auth files, memory files, sessions, local caches, or machine-specific private paths.
  • Keep authenticated MCP connectors disabled by default.
  • Do not add approval rules that auto-allow destructive commands, credential access, publishing, deployments, releases, or broad shell execution.
  • Do not delete, prune, uninstall, drop, truncate, overwrite, or clean files, directories, dependencies, artifacts, local state, or configuration without explicit user approval. Non-destructive edits and validation may continue.
  • Install scripts must back up overwritten files and must not delete user data.
  • Run npm run validate before reporting the repo as push-ready.

Documentation

  • Keep README.md and README.tr.md aligned.
  • Cite official Codex documentation for current behavior.
  • Prefer concise, copy-pasteable commands.
  • When install behavior changes, update docs/install.md, docs/install.tr.md, and docs/security-model.md.

Verification

Use the narrowest meaningful check first:

npm run validate

Before commit or push:

git status --short
git diff --cached

Use Gitleaks when available:

gitleaks detect --redact --no-banner --no-git --verbose
Changes

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.
