Sync

/sync

Usage

/sync                           # Sync system-configs/.claude/ to ~/.claude/
/sync --dry-run                 # Preview changes without syncing
/sync --backup                  # Create backup before syncing (default behavior)

Description

Synchronize all Claude configuration files from system-configs/.claude/ to ~/.claude/ using direct execution with basic validation. The command performs file copying with backup creation and simple validation checks, without deploying multiple agents for a straightforward rsync operation.

Expected Output

Standard Sync Output

Syncing Claude configurations...
Source: system-configs/.claude/ (61 files)
Target: ~/.claude/

Pre-sync validation:
  - Configuration syntax: Valid (15 agents, 37 skills)
  - Target directory: Ready
  - Permissions: OK

Creating backup: ~/.claude.backup.20250909_143022

Synchronizing files:
  Agents: 15 files -> ~/.claude/agents/
  Skills: 37 skills -> ~/.claude/skills/
  Output styles: 8 files -> ~/.claude/output-styles/
  Settings: settings.json, statusline.sh, exit_hook.sh
  CLAUDE.md -> ~/CLAUDE.md

Post-sync validation:
  - File integrity: All files copied successfully
  - Agent configs: 15/15 valid
  - Skills: 37/37 valid

Sync completed successfully:
  Files synced: 61 total
  Backup location: ~/.claude.backup.20250909_143022
  Sync time: 2.3 seconds

Dry Run Output

Preview mode - no changes will be made

Analyzing configurations:
  Source: system-configs/.claude/ (61 files)
  Target: ~/.claude/

Files to sync:
  - 15 agent files -> ~/.claude/agents/
  - 37 skills -> ~/.claude/skills/
  - 8 output style files -> ~/.claude/output-styles/
  - settings.json -> ~/.claude/settings.json
  - statusline.sh -> ~/.claude/statusline.sh
  - exit_hook.sh -> ~/.claude/exit_hook.sh
  - CLAUDE.md -> ~/CLAUDE.md

Preview summary:
  Total files: 61 configurations ready
  Backup would be created before sync
  Estimated time: 2-3 seconds

Validation Error Output

Pre-sync validation failed:

Issues found:
  - Agent syntax error: mobile-engineer.md (line 15: invalid YAML)
  - Permission denied: ~/.claude/ directory not writable

Fix these issues before syncing:
  1. Repair YAML syntax in mobile-engineer.md
  2. Check ~/.claude directory permissions

Run /sync again after addressing these issues.

Behavior

What Gets Synced

Source: ./system-configs/.claude/
Destination: ~/.claude/

Files Synced:
  - agents/*.md           -> ~/.claude/agents/
  - skills/*/             -> ~/.claude/skills/*/ (entire skill directories)
    - Includes: SKILL.md, references/, scripts/, assets/, etc.
  - output-styles/*.md    -> ~/.claude/output-styles/
  - settings.json         -> ~/.claude/settings.json
  - statusline.sh         -> ~/.claude/statusline.sh
  - exit_hook.sh          -> ~/.claude/exit_hook.sh (optional, validated with sh -n)

Also Synced (from system-configs/):
  - CLAUDE.md             -> ~/CLAUDE.md (main Claude configuration)

Excluded:
  - README.md files
  - AGENT_TEMPLATE.md
  - AGENT_CATEGORIES.md
  - SKILL_TEMPLATE.md (in docs/skills/)
  - AUDIT_VERIFICATION_PROTOCOL.md
  - *.tmp, *.backup files

Skills Directory Structure (Anthropic Format):
  Each skill is a directory containing:
  - SKILL.md (required) - Main skill instructions
  - references/ (optional) - API docs, workflow guides
  - scripts/ (optional) - Executable scripts
  - assets/ (optional) - Supporting files
  - examples/ (optional) - Example outputs

  Example:
    skills/code-review/
    ├── SKILL.md
    ├── SECURITY.md
    ├── PERFORMANCE.md
    └── scripts/
        └── run-linters.sh

Validation Strategy

Pre-sync Validation:
  - Basic syntax check for YAML front-matter
  - JSON validation for settings.json
  - POSIX shell syntax check for shell scripts (statusline.sh, exit_hook.sh)
  - Directory permissions and access

Post-sync Validation:
  - File integrity verification
  - Basic configuration syntax check
  - Permissions verification

Implementation

The /sync skill executes the standalone scripts/sync.sh script, which handles all synchronization logic.

#!/bin/sh
# Execute the sync script from the repository
./scripts/sync.sh $ARGUMENTS

Performance Metrics

Execution Time

• Direct execution: 2-4 seconds
• File validation: <1 second
• Backup creation: <1 second
• File synchronization: 1-2 seconds

Benefits of Direct Execution

• Simplified process: No complex agent orchestration for file copying
• Faster execution: Direct operations without agent startup overhead
• Clear output: Simple progress indication
• Automatic backup: Creates backup before changes for manual recovery if needed
• Resource efficient: Minimal system resource usage

Prerequisites

• Source directory system-configs/.claude/ must exist and contain valid configurations
• Target directory permissions must allow read/write access
• rsync must be available for efficient file synchronization

Notes

• Direct execution: Performs file operations directly without agent deployment
• Automatic backup: Creates backup before any changes (restore manually if needed)
• Basic validation: Essential checks without complex multi-agent validation
• Clear logging: Direct progress indication and error reporting
• Integration friendly: Compatible with existing workflows and CI/CD pipelines
• Performance optimized: Fast execution through direct file operations

The /sync skill provides reliable configuration deployment through direct execution, focusing on the essential task of copying files efficiently with basic validation and backup capabilities.
