Task: Configure settings and validate complete system

Description

Configure Claude Code hook system for logging, ensure all script permissions are correct, and perform comprehensive end-to-end testing of the complete hardening system.

Acceptance Criteria

• Add hooks.PreToolUse configuration to .claude/settings.json
• Verify all shell scripts have executable permissions (chmod +x)
• Create required directories: .claude/locks/, .claude/logs/
• Test complete validation workflow with invalid frontmatter
• Test concurrent issue locking with multiple sessions
• Test rate limit handling with forced low GitHub API limits
• Verify NDJSON logging is working and properly formatted
• Test rollback procedure (disable hooks and integration)
• Document installation and configuration steps
• Validate performance impact is within acceptable limits

Technical Details

Implementation approach:

• Update or create .claude/settings.json with hook configuration
• Run comprehensive test scenarios covering all integration points
• Measure performance impact on typical operations
• Document setup and rollback procedures

Key considerations:

• Hook configuration must not break existing Claude Code functionality
• All integration points must work together seamlessly
• Performance impact must be minimal (< 2 seconds added to operations)
• System must be easily reversible for rollback

Code locations/files affected:

• Modify: .claude/settings.json (hook configuration)
• Create: .claude/locks/ directory
• Create: .claude/logs/ directory
• Verify: All scripts in .claude/scripts/pm/ have +x permissions
• Verify: Hook script in .claude/hooks/ has +x permissions

Dependencies

• Task 004: Hook logging system must be implemented
• Task 005: PM command integration must be completed
• All core scripts (001-003) must be working
• Access to GitHub API for end-to-end testing
• Multiple shell sessions for concurrent testing

Effort Estimate

• Size: S
• Hours: 1.5 hours
• Parallel: false (final integration and testing phase)

Definition of Done

• settings.json properly configured with hook system
• All required directories created with proper permissions
• All shell scripts executable and working
• End-to-end testing completed for all major scenarios
• Performance impact measured and within acceptable limits
• Rollback procedure tested and documented
• Installation documentation created
• System ready for production use with all hardening features active
