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 | $0.00023 | $0.01732 |
| Opus 5.5 | $0.00009 | $0.00693 |
| Sonnet 5.5 | $0.00005 | $0.00346 |
| Haiku 4.5 | $0.00002 | $0.00173 |
Grade A, and why
commit-hook-checklist 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.
How it starts
The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
General Guidelines
Output Style
- Never explicitly mention TDD in code, comments, commits, PRs, or issues
- Write natural, descriptive code without meta-commentary about the development process
- The code should speak for itself - TDD is the process, not the product
Beads is available for task tracking. Use mcp__beads__* tools to manage issues (the user interacts via bd commands).
Commit Hook Checklist
Commit hooks are the last automated gate before a change lands. They run on every commit and every push, whether the author is a human in a hurry or an agent that's about to ship something half-baked. A good hook setup catches:
- AI slop: half-finished refactors, broken builds, mocked-out tests left in, dead code from abandoned attempts, generated files out of sync with sources
- Lazy commits: missing types, formatting drift, unsynced lockfiles, migrations that don't match the schema
- Leaked secrets that a
git push --forcecan't take back
This command scans the repo, identifies the language(s), and reports which gates are in place and which are missing.
User arguments:
Commit-hook-checklist: $ARGUMENTS
End of user arguments
Phase 1: Detect language(s)
| Marker | Language |
|---|---|
package.json |
Node.js |
go.mod |
Go |
| Both | polyglot — apply both sections |
| Neither | ask the user what they're working with |
Run the universal checks regardless of language. Then run the language-specific sections that apply.
Phase 2: Run the checks
Scan silently — do not display this list to the user. The summary in Phase 3 is what they see.
Universal (any language)
🔧 Hook runner present
- Husky:
.husky/dir +package.jsonhas"prepare": "husky" - lefthook:
lefthook.ymlorlefthook.yaml - pre-commit framework:
.pre-commit-config.yaml - Native git hooks:
.git/hooks/pre-commitexists, is executable, is not the.samplefile
At least one of these should be present. If none, every other check below is moot.
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.

commit-hook-checklist is a command published in the GitHub repository wbern/agent-instructions (168 stars, last pushed 5mo ago), licensed MIT. It adds 23 tokens to every session and 1,732 once invoked, about $0.0001 per session on Opus 5.5. 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.
