create-hook

create-hook is a command for Claude Code from omril321/automated-notebooklm. It costs 0 tokens per session (1,722 once invoked), scanned A, original, Apache-2.0.

A command for examining a project and creating automated hooks, which are actions that run before or after development tools perform tasks.

In plain words
What is it for?
Use it to inspect project tooling, suggest suitable hooks, create their scripts, and test them—for example, formatting after edits or checking tests before commits.
Why use it?
It connects the project’s existing tests, formatters, linters, type checks, build scripts, and Git workflow so common mistakes are detected automatically.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

create-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 4d 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.

Create Hook Command

Analyze the project, suggest practical hooks, and create them with proper testing.

Your Task (/create-hook)

  1. Analyze environment - Detect tooling and existing hooks
  2. Suggest hooks - Based on your project configuration
  3. Configure hook - Ask targeted questions and create the script
  4. Test & validate - Ensure the hook works correctly

Your Workflow

1. Environment Analysis & Suggestions

Automatically detect the project tooling and suggest relevant hooks:

When TypeScript is detected (tsconfig.json):

  • PostToolUse hook: "Type-check files after editing"
  • PreToolUse hook: "Block edits with type errors"

When Prettier is detected (.prettierrc, prettier.config.js):

  • PostToolUse hook: "Auto-format files after editing"
  • PreToolUse hook: "Require formatted code"

When ESLint is detected (.eslintrc.*):

  • PostToolUse hook: "Lint and auto-fix after editing"
  • PreToolUse hook: "Block commits with linting errors"

When package.json has scripts:

  • test script → "Run tests before commits"
  • build script → "Validate build before commits"

When a git repository is detected:

  • PreToolUse/Bash hook: "Prevent commits with secrets"
  • PostToolUse hook: "Security scan on file changes"

Decision Tree:

Project has TypeScript? → Suggest type checking hooks
Project has formatter? → Suggest formatting hooks
Project has tests? → Suggest test validation hooks
Security sensitive? → Suggest security hooks
+ Scan for additional patterns and suggest custom hooks based on:
  - Custom scripts in package.json
  - Unique file patterns or extensions
  - Development workflow indicators
  - Project-specific tooling configurations

2. Hook Configuration

Start by asking: "What should this hook do?" and offer relevant suggestions from your analysis.

Then understand the context from the user's description and only ask about details you're unsure about:

  1. Trigger timing: When should it run?
    • PreToolUse: Before file operations (can block)
    • PostToolUse: After file operations (feedback/fixes)
    • UserPromptSubmit: Before processing requests
    • Other event types as needed
