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 | $0.00298 | $0.00298 |
| Opus 5 | $0.00149 | $0.00149 |
| Sonnet 5 | $0.00060 | $0.00060 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
grimoire 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 2d 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
Grimoire Agent Protocol
This file is the source of truth for Codex agents working in this repository.
Repository Intent
Grimoire is a personal Codex harnessing repository for reusable skills, one primary plugin, hooks, workflow instructions, and tool integrations. Keep the repository practical and source-owned.
Working Rules
- Prefer small, readable skills over broad catch-all instructions.
- Keep skill names stable and literal so Codex can trigger them predictably.
- Do not add roadmap lists or promised future spells until there is a real skill to commit.
- Use Conventional Commits for commit messages.
- Choose commit and pull request scopes by the smallest durable responsibility affected by the change, not by the broadest package, repository area, or file path.
- Use branch names that expose the Conventional Commit type.
- Verify JSON manifests before committing.
Pull Requests
Before creating or updating a pull request:
- Read
.github/pull_request_template.md. - Use the template's current section structure for the PR body.
- Use a Conventional Commit-style pull request title.
- Choose the pull request title scope by the smallest durable responsibility affected by the change.
- Fill in applicable template content with concrete details.
- Delete template prompts and inapplicable checklist items instead of leaving placeholders behind.
Maintenance Policy
Read docs/maintaining-grimoire.md before changing skills, plugin manifests, repository instructions, hooks, sidecar metadata, publishing checks, or README content.
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.
