Global Hook Setup

One-time setup for global Claude Code hooks. These hooks work across all projects.

Purpose

Installs 8 project-agnostic hooks that enforce DESIGN-v2 determinism:

State machine integrity
Git hygiene
Learning layer (outcome tracking)
Session checkpoints

When to Use

Situation	Action
First time setup	Run full setup
~/.claude/hooks/ missing	Run full setup
After updating hooks	Re-run setup
Manual verification	Run verify script

Quick Check

# Check if global hooks exist
ls ~/.claude/hooks/

Expected output:

verify-state-transition.py
require-commit-before-tested.py
require-outcome-update.py
link-feature-to-trace.py
markdownlint-fix.sh
remind-decision-trace.sh
session-end.sh
feature-commit.sh

Setup Steps

1. Install Hooks

~/.claude/skills/global-hook-setup/scripts/setup-global-hooks.sh

This creates:

~/.claude/hooks/ directory
8 hook files
Executable permissions (chmod +x)

2. Verify Installation

~/.claude/skills/global-hook-setup/scripts/verify-global-hooks.sh

Hooks Installed

Hook	Event	Purpose	Blocks?
`verify-state-transition.py`	PreToolUse	Valid state transitions only	Yes
`require-commit-before-tested.py`	PreToolUse	Git clean before tested	Yes
`require-outcome-update.py`	PreToolUse	Update trace outcome	Yes
`link-feature-to-trace.py`	PostToolUse	Auto-link features	No
`markdownlint-fix.sh`	PostToolUse	Auto-fix .md linting	No
`remind-decision-trace.sh`	SessionEnd	Remind to log decisions	No
`session-end.sh`	SessionEnd	Checkpoint commit	No
`feature-commit.sh`	CLI utility	Feature commit helper	N/A

Note: feature-commit.sh is a CLI utility (not a hook). Use: ~/.claude/hooks/feature-commit.sh <feature-id> [message]

Settings.json Configuration

Setup script configures ~/.claude/settings.json:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Write|Edit",
        "hooks": [
          {"type": "command", "command": "python3 ~/.claude/hooks/verify-state-transition.py"},
          {"type": "command", "command": "python3 ~/.claude/hooks/require-commit-before-tested.py"},
          {"type": "command", "command": "python3 ~/.claude/hooks/require-outcome-update.py"}
        ]
      }
    ],
    "PostToolUse": [
      {
        "matcher": "Write|Edit",
        "hooks": [
          {"type": "command", "command": "python3 ~/.claude/hooks/link-feature-to-trace.py"},
          {"type": "command", "command": "/bin/bash ~/.claude/hooks/markdownlint-fix.sh"}
        ]
      }
    ],
    "SessionEnd": [
      {
        "hooks": [
          {"type": "command", "command": "/bin/bash ~/.claude/hooks/session-end.sh"},
          {"type": "command", "command": "/bin/bash ~/.claude/hooks/remind-decision-trace.sh"}
        ]
      }
    ]
  }
}

Exit Criteria (Code Verified)

# Directory exists
[ -d ~/.claude/hooks ]

# All hooks exist and executable
[ -x ~/.claude/hooks/verify-state-transition.py ]
[ -x ~/.claude/hooks/require-commit-before-tested.py ]
[ -x ~/.claude/hooks/require-outcome-update.py ]
[ -x ~/.claude/hooks/link-feature-to-trace.py ]
[ -x ~/.claude/hooks/markdownlint-fix.sh ]
[ -x ~/.claude/hooks/remind-decision-trace.sh ]
[ -x ~/.claude/hooks/session-end.sh ]
[ -x ~/.claude/hooks/feature-commit.sh ]

# Verify script passes
~/.claude/skills/global-hook-setup/scripts/verify-global-hooks.sh

Scripts

Script	Purpose
`setup-global-hooks.sh`	Main setup (install + configure + validate)
`configure-settings.py`	Configure settings.json with hook entries
`validate-settings.py`	Validate hooks configured in settings.json
`verify-global-hooks.sh`	Verify hook files exist
`install-hooks.sh`	Copy from templates

Troubleshooting

Problem	Solution
Hooks not found	Re-run setup script
Permission denied	Run: `chmod +x ~/.claude/hooks/*`
Verification fails	Check hook syntax, ensure python3 available
Already exists	Setup is idempotent, safe to re-run

Next Steps

After global hooks: Set up project-specific hooks with project-hook-setup skill.
