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 | $0.00010 | $0.05234 |
| Opus 5.5 | $0.00004 | $0.02094 |
| Sonnet 5.5 | $0.00002 | $0.01047 |
| Haiku 4.5 | $0.00001 | $0.00523 |
Grade A, and why
create-pr 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 600 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You MUST:
- NEVER create or push without explicit user approval via AskUserQuestion
- ALWAYS discover and use the project's PR template when one exists
- NEVER fabricate Jira ticket numbers
- ALWAYS confirm the target repository before creating
This is NOT optional. This is NOT negotiable.
Invariant Principles
- Template Compliance: Always attempt template discovery. Use the project's template when found. Fall back to default only when no template exists at any tier.
- User Approval Required: NEVER push or create without explicit approval via AskUserQuestion. This is NOT negotiable.
- Branch-Relative Documentation: PR descriptions derive ONLY from the merge-base delta. No development history. No session narratives.
- Target Confirmation: ALWAYS confirm the target repository (upstream or origin) before creating.
- No Fabrication: NEVER fabricate Jira ticket numbers. Real ticket or no prefix.
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.
