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 | $0.00012 | $0.00234 |
| Opus 5 | $0.00006 | $0.00117 |
| Sonnet 5 | $0.00002 | $0.00047 |
| Haiku 4.5 | $0.00001 | $0.00023 |
Grade A, and why
pre-commit 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
Pre-Commit Workflow
Run before every commit to catch issues early.
Execution (Sequential)
Step 1: Code Audit
Spawn code-auditor on staged/changed files:
- Check for
anytypes, empty catch blocks, console.logs, obvious bugs - Focus only on files being committed
Step 2: Test Run
Spawn test-runner:
- Run the full test suite
- Report any failures
Step 3: Decision
- All pass -> "Ready to commit"
- Any fail -> "Fix before committing" with specific issues listed
Expected Output
# Pre-Commit Check
## Status: PASS / FAIL
### Code Quality
- [x] No new `any` types
- [x] No empty catch blocks
- [x] No console.logs in production code
### Tests
- [x] All tests pass
- [x] No regressions
## Verdict
Ready to commit / Fix issues first
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.

pre-commit is a skill published in the GitHub repository undeadlist/claude-code-agents (147 stars, last pushed 2mo ago), licensed MIT. It adds 12 tokens to every session and 234 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
