Claude Code Hooks Setup

You are helping the user set up production safety hooks for Claude Code.

Available Hooks

Hook	Purpose	Event	Matcher
context-monitor.sh	Context window warnings (40% → 25% → 20% → 15%)	PostToolUse	all
activity-logger.sh	JSONL audit trail of file changes	PostToolUse	Edit\|Write
syntax-check.sh	Auto syntax validation after edits	PostToolUse	Edit\|Write
decision-warn.sh	Alerts on edits to sensitive paths	PreToolUse	Edit\|Write
cdp-safety-check.sh	Blocks raw WebSocket CDP construction	PreToolUse	Bash
proof-log-session.sh	5W1H session summaries	Stop, PreCompact	all
session-start-marker.sh	Records session start time	PostToolUse	all
no-ask-human.sh	Blocks questions during autonomous operation	PostToolUse	all
branch-guard.sh	Blocks pushes to main/master	PreToolUse	Bash
error-gate.sh	Blocks external actions when errors exist	PreToolUse	Bash

Setup Profiles

Minimal (recommended for beginners)

context-monitor.sh + syntax-check.sh
Catches the two most common failure modes

Standard (recommended for most users)

All of minimal + activity-logger.sh + branch-guard.sh + decision-warn.sh + proof-log-session.sh + session-start-marker.sh
Good balance of safety and visibility

Autonomous (for unattended operation)

All hooks enabled including no-ask-human.sh and error-gate.sh
Maximum safety for headless/autonomous Claude Code sessions

Steps

Ask which profile the user wants (or let them pick individual hooks)
The plugin's hooks.json already configures the autonomous profile by default
Help configure environment variables if needed:
- ```
CC_CONTEXT_MISSION_FILE
```
  — path to mission.md (default:
```
$HOME/mission.md
```
  )
- ```
CC_ACTIVITY_LOG
```
  — path to activity log (default:
```
$HOME/claude-activity-log.jsonl
```
  )
- ```
CC_MONITORED_DIRS
```
  — colon-separated paths for decision-warn (default:
```
$HOME/bin:$HOME/.claude/hooks
```
  )
- ```
CC_PROTECT_BRANCHES
```
  — colon-separated branch names (default:
```
main:master
```
  )
- ```
CC_ERROR_LOG
```
  — path to error tracker (default:
```
$HOME/.claude/error-tracker.log
```
  )
- ```
CC_PROOF_LOG_DIR
```
  — path to proof logs (default:
```
$HOME/proof-log
```
  )
Verify the setup works by running a quick test
