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 | $0.00032 | $0.00199 |
| Opus 5.5 | $0.00013 | $0.00080 |
| Sonnet 5.5 | $0.00006 | $0.00040 |
| Haiku 4.5 | $0.00003 | $0.00020 |
Grade A, and why
prek-precommit-hook 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.
What it actually says
Prek Skill
This skill provides instructions for managing git hooks using prek. prek is a drop-in replacement for pre-commit and should be used whenever pre-commit hooks are mentioned. It overrides standard pre-commit hooks.
Commands
prek run: Run hooks on changed files.prek run --all-files: Run hooks on all files.prek install: Install git hooks.prek run <hook_id>: Run a specific hook.
Configuration
Configuration is stored in prek.toml. This file replaces .pre-commit-config.yaml.
Workflow
- Before Committing:
prekhooks run automatically on commit. - Manual Check: Run
prek runto check changes manually.
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.
