CODITECT Standard: Hooks

Version: 1.0.0 Status: Approved Last Updated: December 3, 2025 Authority: Based on Anthropic Official Documentation

---

Executive Summary

This standard defines the authoritative specification for hooks in the CODITECT framework. Hooks are event-triggered scripts that execute at specific points in the Claude Code lifecycle, enabling automation, validation, and workflow customization.

Key Requirements:

• Hooks MUST be shell scripts (.sh) or Python scripts (.py) in .claude/hooks/ or ~/.claude/hooks/
• Hooks MUST be configured in .claude/settings.json with event type and matcher
• Hooks MUST return proper exit codes (0=success, 2=blocking, other=error)
• Hooks MUST read JSON input from stdin and write JSON output to stdout
• Hooks SHOULD complete within 5 seconds (30 second hard timeout)
• Hooks MUST NOT make destructive changes without user awareness

Compliance Target: All CODITECT hooks must achieve Grade B (80%) or higher within 30 days of this standard publication.

Hook Events

10 Standard Hook Events

Claude Code supports 10 lifecycle events where hooks can be triggered:

Event	Trigger	Can Block	Blocking Exit Code	Use Cases
PreToolUse	Before tool execution	✅ Yes	2	Validation, security checks, logging
PostToolUse	After tool completion	❌ No	N/A	Formatting, cleanup, notifications
UserPromptSubmit	User submits prompt	✅ Yes	2	Prompt enhancement, validation, filtering
Stop	User stops operation	✅ Yes	2	Cleanup, state saving
SubagentStop	Subagent completes	✅ Yes	2	Subagent coordination, result validation
PermissionRequest	Permission needed	❌ No	N/A	Auto-approval, logging, notifications
Notification	System notification	❌ No	N/A	Alerts, integrations, logging
PreCompact	Before context compaction	❌ No	N/A	Backup, context preservation
SessionStart	Session begins/resumes	❌ No	N/A	Context loading, initialization
SessionEnd	Session ends	❌ No	N/A	Cleanup, state persistence

Event Selection Guidelines

Use PreToolUse when:

• Validating tool inputs before execution
• Enforcing security policies
• Checking prerequisites
• Preventing destructive operations

Use PostToolUse when:

• Formatting tool outputs
• Running cleanup operations
• Sending notifications
• Logging results

Use UserPromptSubmit when:

• Enhancing user prompts with context
• Validating prompt format
• Filtering sensitive information
• Adding system instructions

Use SessionStart when:

• Loading project context
• Initializing environment
• Restoring previous state
• Setting up logging

Use SessionEnd when:

• Saving session state
• Cleaning up resources
• Creating backups
• Generating reports

File Structure

Directory Locations

Hooks can be defined at two scopes:

Scope	Directory	Shown As	Use Case
Project	.claude/hooks/	(project)	Project-specific automation
User	~/.claude/hooks/	(user)	Personal hooks across all projects

File Naming

Pattern: {event}-{purpose}.{ext} (kebab-case)

Extensions:

• .sh - Shell scripts (bash, zsh)
• .py - Python scripts

Examples:

• ✅ pre-tool-component-validation.sh
• ✅ post-tool-format-output.py
• ✅ user-prompt-enhance-context.sh
• ❌ validation.sh (missing event prefix)
• ❌ PreToolValidation.py (camelCase - wrong)
• ❌ pre_tool_validation.sh (snake_case - wrong)

Length: Maximum 64 characters (filename without extension)

File Permissions

Shell scripts:

chmod +x .claude/hooks/pre-tool-component-validation.sh

Python scripts:

# Must have shebang
#!/usr/bin/env python3

# Optional: make executable
chmod +x .claude/hooks/post-tool-format-output.py

---

Exit Code Conventions

CRITICAL: Hooks communicate results via exit codes.

Standard Exit Codes

Exit Code	Meaning	Behavior	When to Use
0	Success	Continue normally, stdout shown in transcript	Hook completed successfully
2	Block (for blocking events)	Prevent action, show stdout as error	Validation failed, prevent operation
1 or other	Non-blocking error	Continue, stderr logged	Warning condition, non-critical failure

Exit Code Guidelines

✅ DO:

• Exit 0 for successful validation/operation
• Exit 2 to block operation (PreToolUse, UserPromptSubmit, Stop, SubagentStop)
• Exit 1 for warnings that shouldn't block
• Document exit conditions in hook comments

❌ DON'T:

• Exit 2 for non-blocking events (PostToolUse, Notification, PreCompact, SessionStart, SessionEnd)
• Exit 0 when validation actually failed
• Use random exit codes (stick to 0, 1, 2)
• Forget to exit (script hangs)

Examples

Shell Script:

#!/bin/bash
# Exit code examples

# Success - allow operation
if validation_passed; then
    echo '{"continue": true, "message": "Validation passed"}'
    exit 0
fi

# Block operation (PreToolUse event)
if critical_issue; then
    echo '{"continue": false, "message": "Critical validation failed"}'
    exit 2
fi

# Warning - continue but log
if minor_issue; then
    echo '{"continue": true, "message": "Warning: minor issue detected"}' >&2
    exit 1
fi

Python Script:

#!/usr/bin/env python3
import sys
import json

# Success
def success(message):
    print(json.dumps({"continue": True, "message": message}))
    sys.exit(0)

# Block operation
def block(message):
    print(json.dumps({"continue": False, "message": message}))
    sys.exit(2)

# Warning
def warn(message):
    print(json.dumps({"continue": True, "message": message}), file=sys.stderr)
    sys.exit(1)

---

Input/Output Format

Input Format (stdin)

Hooks receive JSON input via stdin containing event details:

{
  "event": "PreToolUse",
  "tool_name": "Write",
  "tool_input": {
    "file_path": "/path/to/file.py",
    "content": "new file content"
  },
  "context": {
    "session_id": "abc123",
    "working_dir": "/path/to/project",
    "timestamp": "2025-12-03T10:30:00Z"
  }
}

Output Format (stdout)

Hooks MUST output JSON to stdout:

Success:

{
  "continue": true,
  "message": "Operation allowed"
}

Block (exit 2):

{
  "continue": false,
  "message": "Operation blocked: validation failed"
}

With Additional Data:

{
  "continue": true,
  "message": "Validation passed",
  "metadata": {
    "checks_passed": 5,
    "checks_failed": 0,
    "duration_ms": 150
  }
}

Reading Input

Shell (using jq):

#!/bin/bash
json=$(cat)  # Read all stdin
event=$(echo "$json" | jq -r '.event')
tool_name=$(echo "$json" | jq -r '.tool_name')
file_path=$(echo "$json" | jq -r '.tool_input.file_path // empty')

Python:

#!/usr/bin/env python3
import json
import sys

# Read all stdin
hook_input = json.load(sys.stdin)
event = hook_input.get('event')
tool_name = hook_input.get('tool_name')
file_path = hook_input.get('tool_input', {}).get('file_path')

---

Configuration

settings.json Schema

Hooks are configured in .claude/settings.json:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "tool_name = \"Write\"",
        "hooks": [
          {
            "type": "command",
            "command": ".claude/hooks/component-validation.sh"
          }
        ]
      }
    ],
    "PostToolUse": [
      {
        "matcher": "tool_name = \"Bash\" && tool_input.command contains \"git commit\"",
        "hooks": [
          {
            "type": "command",
            "command": "python3 .claude/hooks/post-commit-quality.py"
          }
        ]
      }
    ],
    "UserPromptSubmit": [
      {
        "matcher": "*",
        "hooks": [
          {
            "type": "prompt",
            "prompt": "Enhance the user's prompt with project context from README.md"
          }
        ]
      }
    ]
  }
}

Hook Configuration Fields

Field	Required	Type	Description
matcher	✅ Yes	string	Pattern to match event (use * for all)
type	✅ Yes	"command" or "prompt"	Hook execution type
command	For type="command"	string	Path to hook script
prompt	For type="prompt"	string	LLM prompt for evaluation

Matcher Syntax

Operators:

• = - Equals
• != - Not equals
• contains - String contains
• matches - Regex match
• && - AND
• || - OR

Examples:

// Match specific tool
"tool_name = \"Write\""

// Match file pattern
"tool_input.file_path matches \".*\\.py$\""

// Complex condition
"tool_name = \"Write\" && tool_input.file_path contains \"/.coditect/\""

// Match all
"*"

Hook Types

1. Command Hooks Execute external scripts:

{
  "type": "command",
  "command": ".claude/hooks/validation.sh"
}

2. Prompt Hooks Use LLM to evaluate/transform:

{
  "type": "prompt",
  "prompt": "Analyze if this code change introduces security vulnerabilities"
}

---

Security Best Practices

1. Input Validation

CRITICAL: Never trust hook input directly.

❌ Dangerous:

#!/bin/bash
file_path=$(cat | jq -r '.tool_input.file_path')
cat "$file_path"  # Arbitrary file read!

✅ Safe:

#!/bin/bash
file_path=$(cat | jq -r '.tool_input.file_path // empty')

# Validate path is within project
if [[ ! "$file_path" =~ ^/safe/project/path/ ]]; then
    echo '{"continue": false, "message": "Invalid file path"}'
    exit 2
fi

# Additional validation
if [[ -z "$file_path" ]] || [[ ! -f "$file_path" ]]; then
    echo '{"continue": false, "message": "File not found"}'
    exit 2
fi

2. Command Injection Prevention

❌ Vulnerable:

import subprocess
file_path = hook_input['tool_input']['file_path']
subprocess.run(f"cat {file_path}", shell=True)  # Injection!

✅ Safe:

import subprocess
from pathlib import Path

file_path = hook_input['tool_input']['file_path']

# Validate and sanitize
safe_path = Path(file_path).resolve()
if not str(safe_path).startswith('/safe/project/'):
    block("Invalid path")

# Use list form (no shell)
subprocess.run(["cat", str(safe_path)], shell=False, check=True)

3. Environment Variable Safety

#!/bin/bash

# Clear sensitive environment
unset AWS_ACCESS_KEY_ID
unset AWS_SECRET_ACCESS_KEY

# Use explicit PATH
export PATH="/usr/local/bin:/usr/bin:/bin"

# Rest of hook logic

4. Secret Handling

❌ DON'T:

# Never log secrets
echo "API_KEY=$API_KEY"

# Never write secrets to files
echo "$SECRET" > /tmp/secret.txt

# Never pass secrets in commands
curl -H "Authorization: Bearer $TOKEN" ...

✅ DO:

# Use secret managers
SECRET=$(vault read -field=value secret/api-key)

# Redact in logs
echo "API call with key: [REDACTED]"

# Use environment variables securely
export API_KEY="$SECRET"
# Command uses $API_KEY internally

5. File System Safety

#!/bin/bash

# Restrict operations to project directory
REPO_ROOT="$(git rev-parse --show-toplevel)"

# Validate all paths
validate_path() {
    local path="$1"
    # Resolve to absolute path
    local abs_path="$(cd "$(dirname "$path")" && pwd)/$(basename "$path")"

    # Check if within repo
    if [[ ! "$abs_path" =~ ^$REPO_ROOT/ ]]; then
        echo '{"continue": false, "message": "Path outside repository"}'
        exit 2
    fi
}

6. Timeout Protection

Shell:

#!/bin/bash

# Set timeout
timeout 5s python3 validation.py

# Check exit code
if [ $? -eq 124 ]; then
    echo '{"continue": false, "message": "Validation timed out"}'
    exit 2
fi

Python:

import signal

def timeout_handler(signum, frame):
    raise TimeoutError("Hook exceeded 5 second timeout")

signal.signal(signal.SIGALRM, timeout_handler)
signal.alarm(5)  # 5 second timeout

try:
    # Hook logic here
    validate_component()
finally:
    signal.alarm(0)  # Cancel alarm

---

Performance Guidelines

1. Speed Requirements

Priority	Timeout	Target	Use Case
Critical	5s	<1s	PreToolUse, UserPromptSubmit
Standard	30s	<5s	PostToolUse, validation hooks
Background	60s	<30s	SessionEnd, cleanup hooks

2. Optimization Strategies

Cache Results:

import hashlib
import json
from pathlib import Path

CACHE_DIR = Path.home() / ".cache" / "claude-hooks"
CACHE_DIR.mkdir(parents=True, exist_ok=True)

def get_cache_key(data):
    """Generate cache key from input"""
    return hashlib.sha256(json.dumps(data, sort_keys=True).encode()).hexdigest()

def cached_validation(hook_input):
    cache_key = get_cache_key(hook_input)
    cache_file = CACHE_DIR / f"{cache_key}.json"

    # Check cache
    if cache_file.exists():
        with open(cache_file) as f:
            return json.load(f)

    # Run validation
    result = validate(hook_input)

    # Store in cache
    with open(cache_file, 'w') as f:
        json.dump(result, f)

    return result

Parallel Processing:

import concurrent.futures

def validate_multiple_files(file_list):
    with concurrent.futures.ThreadPoolExecutor(max_workers=4) as executor:
        futures = [executor.submit(validate_file, f) for f in file_list]
        results = [f.result() for f in concurrent.futures.as_completed(futures)]
    return all(results)

Early Exit:

def validate_component(content):
    # Check critical issues first (fast checks)
    if not has_yaml_frontmatter(content):
        return False  # Exit immediately

    # Then run expensive checks
    if not deep_validation(content):
        return False

    return True

3. Resource Management

#!/usr/bin/env python3
import resource
import sys

# Limit memory usage (100MB)
resource.setrlimit(resource.RLIMIT_AS, (100 * 1024 * 1024, 100 * 1024 * 1024))

# Limit CPU time (5 seconds)
resource.setrlimit(resource.RLIMIT_CPU, (5, 5))

try:
    # Hook logic
    pass
except MemoryError:
    print('{"continue": false, "message": "Hook exceeded memory limit"}')
    sys.exit(2)

Migration Guide

Upgrading Existing Hooks

Step 1: Add Proper Shebang

Before:

# Missing shebang
echo "Hook logic"

After:

#!/bin/bash
set -euo pipefail  # Exit on error, undefined var, pipe failure

echo "Hook logic"

Step 2: Standardize Exit Codes

Before:

if validation_failed; then
    exit 1  # Wrong - should be 2 for blocking
fi

After:

if validation_failed; then
    echo '{"continue": false, "message": "Validation failed"}'
    exit 2  # Correct - blocks operation
fi

Step 3: Add JSON I/O

Before:

FILE_PATH="$1"  # Command line argument
echo "Validated $FILE_PATH"

After:

# Read from stdin
json=$(cat)
FILE_PATH=$(echo "$json" | jq -r '.tool_input.file_path')

# Output JSON
echo '{"continue": true, "message": "Validated '"$FILE_PATH"'"}'

Step 4: Add Security Validation

Before:

file_path = sys.argv[1]
with open(file_path) as f:
    content = f.read()

After:

import json
from pathlib import Path

hook_input = json.load(sys.stdin)
file_path = hook_input['tool_input']['file_path']

# Validate path
safe_path = Path(file_path).resolve()
repo_root = Path.cwd()

if not str(safe_path).startswith(str(repo_root)):
    print(json.dumps({"continue": False, "message": "Path outside repo"}))
    sys.exit(2)

with open(safe_path) as f:
    content = f.read()

Troubleshooting

Issue: Hook Not Triggering

Symptoms: Hook never executes despite matching configuration

Causes:

1. Hook not configured in settings.json
2. Matcher pattern doesn't match event
3. File permissions incorrect

Solutions:

# Check configuration
jq '.hooks' .claude/settings.json

# Verify file permissions
ls -la .claude/hooks/your-hook.sh
chmod +x .claude/hooks/your-hook.sh

# Test matcher pattern
# (Add debug logging to hook to confirm it's being called)

---

Issue: Hook Blocks All Operations

Symptoms: Hook always exits 2, blocking everything

Causes:

1. Logic error in validation
2. Missing success path
3. Wrong exit code for non-blocking event

Solutions:

# Add debug output
#!/bin/bash
echo "DEBUG: Hook input: $(cat)" >&2  # Log to stderr

# Ensure success path exists
if [ condition ]; then
    exit 0  # Success
else
    exit 2  # Block
fi

---

Issue: Hook Times Out

Symptoms: Operations hang, eventually timeout after 30s

Causes:

1. Infinite loop
2. Waiting for user input
3. Network requests without timeout
4. Large file processing

Solutions:

# Add timeout to subprocesses
timeout 5s python3 validation.py

# Use non-blocking I/O
# Avoid: input(), read without timeout
# Use: subprocess.run(timeout=5)

---

Issue: Security Error - Command Injection

Symptoms: Hook executes arbitrary commands, security vulnerability

Cause: Unsanitized input passed to shell

Solution:

# WRONG
import subprocess
file = hook_input['tool_input']['file_path']
subprocess.run(f"cat {file}", shell=True)  # Injection!

# RIGHT
import subprocess
from pathlib import Path

file = Path(hook_input['tool_input']['file_path']).resolve()
subprocess.run(["cat", str(file)], shell=False, check=True)

---

Issue: Hook Performance Degradation

Symptoms: Hook slows down over time

Causes:

1. Cache not being cleaned
2. Log files growing unbounded
3. Memory leaks

Solutions:

# Clean old cache entries
import time
from pathlib import Path

CACHE_DIR = Path.home() / ".cache" / "claude-hooks"
MAX_AGE = 7 * 24 * 3600  # 7 days

for cache_file in CACHE_DIR.glob("*.json"):
    if time.time() - cache_file.stat().st_mtime > MAX_AGE:
        cache_file.unlink()

# Rotate log files
import os

LOG_FILE = ".claude/hooks/hook.log"
MAX_SIZE = 10 * 1024 * 1024  # 10MB

if os.path.exists(LOG_FILE) and os.path.getsize(LOG_FILE) > MAX_SIZE:
    os.rename(LOG_FILE, f"{LOG_FILE}.old")
