Creating Claude Code Hooks

Use this skill when creating, improving, or publishing Claude Code hooks. Provides essential guidance on hook format, event handling, I/O conventions, and package structure.

When to Use This Skill

Activate this skill when:

User asks to create a new Claude Code hook
User wants to publish a hook as a PRPM package
User needs to understand hook format or events
User is troubleshooting hook execution
User asks about hook vs skill vs command differences

Quick Reference

Hook File Format

Aspect	Requirement
Location	`.claude/hooks/<event-name>`
Format	Executable file (shell, TypeScript, Python, etc.)
Permissions	Must be executable (`chmod +x`)
Shebang	Required (`#!/bin/bash` or `#!/usr/bin/env node`)
Input	JSON via stdin
Output	Text via stdout (shown to user)
Exit Codes	`0` = success, `2` = block, other = error

Available Events

Event	When It Fires	Common Use Cases
`session-start`	New session begins	Environment setup, logging, checks
`user-prompt-submit`	Before user input processes	Validation, enhancement, filtering
`tool-call`	Before tool execution	Permission checks, logging, modification
`assistant-response`	After assistant responds	Formatting, logging, cleanup

Hook Format Requirements

File Location

Project hooks:

.claude/hooks/session-start
.claude/hooks/user-prompt-submit

User-global hooks:

~/.claude/hooks/session-start
~/.claude/hooks/tool-call

Executable Requirements

Every hook MUST:

Have a shebang line:

#!/bin/bash
# or
#!/usr/bin/env node
# or
#!/usr/bin/env python3

Be executable:

chmod +x .claude/hooks/session-start

Handle JSON input from stdin:

#!/bin/bash
INPUT=$(cat)
FILE=$(echo "$INPUT" | jq -r '.input.file_path // empty')

Exit with appropriate code:

exit 0  # Success
exit 2  # Block operation
exit 1  # Error (logs but continues)

Input/Output Format

JSON Input Structure

Hooks receive JSON via stdin with event-specific data:

{
  "event": "tool-call",
  "timestamp": "2025-01-15T10:30:00Z",
  "session_id": "abc123",
  "current_dir": "/path/to/project",
  "input": {
    "file_path": "/path/to/file.ts",
    "command": "npm test",
    "old_string": "...",
    "new_string": "..."
  }
}

Stdout Output

Normal output shows in transcript
Empty output runs silently
Use stderr (>&2) for errors

Exit Codes

Code	Meaning	Behavior
`0`	Success	Continue normally
`2`	Block	Stop operation, show error
`1` or other	Error	Log error, continue

Schema Validation

Hooks should validate against the JSON schema:

Schema URL: https://github.com/pr-pm/prpm/blob/main/packages/converters/schemas/claude-hook.schema.json

Required frontmatter fields:

name - Hook identifier (lowercase, hyphens only)
description - What the hook does
event - Event type (optional, inferred from filename)
language - bash, typescript, javascript, python, binary (optional)
hookType: "hook" - For round-trip conversion

Common Mistakes

Mistake	Problem	Solution
Not quoting variables	Breaks on spaces	Always use `"$VAR"`
Missing shebang	Won't execute	Add `#!/bin/bash`
Not executable	Permission denied	Run `chmod +x hook-file`
Logging to stdout	Clutters transcript	Use stderr: `echo "log" >&2`
Wrong exit code	Doesn't block when needed	Use `exit 2` to block
No input validation	Security risk	Always validate JSON fields
Slow operations	Blocks Claude	Run in background or use PostToolUse
Absolute paths missing	Can't find scripts	Use `$CLAUDE_PLUGIN_ROOT`

Basic Hook Examples

Shell Script Hook

#!/bin/bash
# .claude/hooks/session-start

# Log session start
echo "Session started at $(date)" >> ~/.claude/session.log

# Check environment
if ! command -v node &> /dev/null; then
  echo "Warning: Node.js not installed" >&2
fi

# Output to user
echo "Development environment ready"
exit 0

TypeScript Hook

#!/usr/bin/env node
// .claude/hooks/user-prompt-submit

import { readFileSync } from 'fs';

// Read JSON from stdin
const input = readFileSync(0, 'utf-8');
const data = JSON.parse(input);

// Validate prompt
if (data.prompt.includes('API_KEY')) {
  console.error('Warning: Prompt may contain secrets');
  process.exit(2); // Block
}

console.log('Prompt validated');
process.exit(0);

Best Practices

1. Keep Hooks Fast

Target < 100ms for PreToolUse hooks:

Cache results where possible
Run heavy operations in background
Use specific matchers, not wildcards

2. Handle Errors Gracefully

# Check dependencies exist
if ! command -v jq &> /dev/null; then
  echo "jq not installed, skipping" >&2
  exit 0
fi

# Validate input
FILE=$(echo "$INPUT" | jq -r '.input.file_path // empty')
if [[ -z "$FILE" ]]; then
  echo "No file path provided" >&2
  exit 1
fi

3. Use Shebangs

Always start with shebang:

#!/bin/bash
#!/usr/bin/env node
#!/usr/bin/env python3

4. Secure Sensitive Files

BLOCKED=(".env" ".env.*" "*.pem" "*.key")
for pattern in "${BLOCKED[@]}"; do
  case "$FILE" in
    $pattern)
      echo "Blocked: $FILE is sensitive" >&2
      exit 2
      ;;
  esac
done

5. Quote All Variables

# WRONG - breaks on spaces
prettier --write $FILE

# RIGHT - handles spaces
prettier --write "$FILE"

6. Log for Debugging

LOG_FILE=~/.claude-hooks/debug.log

# Log to file
echo "[$(date)] Processing $FILE" >> "$LOG_FILE"

# Log to stderr (shows in transcript)
echo "Hook running..." >&2

# Session Logger Hook

Logs Claude Code session activity for tracking and debugging.

## Installation

This hook will be installed to `.claude/hooks/session-start`.

## Behavior

- Logs session start time to `~/.claude/session.log`
- Displays environment status
- Runs silent dependency checks

## Requirements

- bash 4.0+
- write access to `~/.claude/`

## Source Code

\`\`\`bash
#!/bin/bash
echo "Session started at $(date)" >> ~/.claude/session.log
echo "Environment ready"
exit 0
\`\`\`

Publishing Process

# Test locally first
prpm test

# Publish to registry
prpm publish

# Version bumps
prpm publish patch  # 1.0.0 -> 1.0.1
prpm publish minor  # 1.0.0 -> 1.1.0
prpm publish major  # 1.0.0 -> 2.0.0

Security Requirements

Input Validation

# Parse JSON safely
INPUT=$(cat)
if ! FILE=$(echo "$INPUT" | jq -r '.input.file_path // empty' 2>&1); then
  echo "JSON parse failed" >&2
  exit 1
fi

# Validate field exists
[[ -n "$FILE" ]] || exit 1

Path Sanitization

# Prevent directory traversal
if [[ "$FILE" == *".."* ]]; then
  echo "Path traversal detected" >&2
  exit 2
fi

# Keep in project directory
if [[ "$FILE" != "$CLAUDE_PROJECT_DIR"* ]]; then
  echo "File outside project" >&2
  exit 2
fi
