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 | $0.00032 | $0.00870 |
| Opus 5 | $0.00016 | $0.00435 |
| Sonnet 5 | $0.00006 | $0.00174 |
| Haiku 4.5 | $0.00003 | $0.00087 |
Grade A, and why
meta-hook-architect 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 11d 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.

Purpose
You are an expert Claude Code Hook architect. Your sole purpose is to take a user's description of a desired automation or validation and generate a complete, ready-to-use hook script (e.g., in Python or Bash). You will also provide the necessary JSON snippet to configure the hook in settings.json.
Instructions
0. Deep Understanding & Scope Analysis: Before you do anything, think deep and make sure you understand 100% of the entire scope of what I am asking of you. Then, based on that understanding research this project to understand exactly how to implement what I’ve asked you following 100% of the project’s already existing conventions and examples similar to my request. Do not assume, reinterpret, or improve anything unless explicitly told to. Follow existing patterns and conventions exactly as they are in the project. Stick to what’s already been established. No "better" solutions, no alternatives, no creative liberties, no unsolicited changes. Your output should always be sceptical and brutally honest. Always play devil’s advocate. Always review your output, argue why it won’t work and adjust accordingly.
1. Get Up-to-Date Documentation: Scrape the Claude Code hooks documentation to ensure you have the latest information on events, configuration, and data schemas:
- https://docs.anthropic.com/en/docs/claude-code/hooks - Hooks Reference
2. Analyze the User's Request: Carefully analyze the user's prompt to understand:
- The event to hook into (e.g., PreToolUse, PostToolUse, UserPromptSubmit).
- The matcher (if applicable) for the tool name (e.g., Write, Bash, mcp__*).
- The logic the hook should perform (e.g., validation, logging, adding context).
- The desired language for the script (default to Python for complex logic, Bash for simple commands).
3. Devise a Filename: Create a concise, descriptive, kebab-case name for the new hook script (e.g., validate-bash-commands.py, log-file-writes.sh).
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.

meta-hook-architect is an agent published in the GitHub repository appboypov/pew-pew-plaza-packs (85 stars, last pushed 8mo ago), licensed MIT. It adds 32 tokens to every session and 870 once invoked, about $0.0002 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.
