🧠 Understanding Agent Skills

What Are Agent Skills?

Agent Skills are automatic capabilities that Claude activates based on your conversation context - no slash commands needed!

When you install a plugin with Agent Skills, Claude can detect when you need help with that domain and automatically provide expert guidance.

File Structure

your-plugin/
└── skills/
    └── skill-adapter/
        └── SKILL.md       # Agent skill definition

SKILL.md Format

---
name: Database Backup Automator
description: |
  Automatically handles database backup operations when user mentions
  backup, restore, or data protection needs.

## What This Skill Does
Multi-phase database backup workflow with validation...

## When It Activates
- "I need to backup my database"
- "How do I restore from backup?"
- "Set up automated backups"

How It Works in Practice

1. Install a plugin with Agent Skills:

/plugin install postgres-backup-pro@claude-code-plugins-plus

2. Mention your need naturally in conversation:

"I need to backup my production PostgreSQL database before the migration"

3. Claude automatically:

• Detects the backup skill is relevant
• Activates the Database Backup Automator skill
• Guides you through: connection → backup → verification → storage
• No slash commands needed!

4. You get expert help with:

• Multi-phase workflows (analysis → execution → validation)
• Code examples and error handling
• Best practices built-in
• Context-aware recommendations

Key Difference: Skills vs Commands

Result: More natural, conversational development workflow where Claude proactively helps based on context.

📦 Technical Highlights

Production Infrastructure

• Smart rate limiting: 45-60s per plugin, 71.6% API quota remaining
• SQLite audit trail: Complete compliance tracking
• Turso disaster recovery: Off-site backup with 30min recovery time
• Idempotent operations: Fault-tolerant, safe to restart
• Real-time observability: Unbuffered logging throughout

Optimization Journey

• Started: 90-120s delays (ultra-conservative)
• Data-driven optimization: Cut to 45-60s after 12 hours of metrics
• Result: 2x faster with 3x safety margin maintained
• Completion: 1:30 AM instead of 5:30 AM (4 hours saved)

Quality Comparison

• Our Agent Skills: 3,210 bytes average, up to 8,488 bytes
• Anthropic's Examples: ~500 bytes (template-skill)
• Improvement: 17x larger with multi-phase workflows, code examples

🛠️ System Design

Rate Limiting Strategy:

# Base delay with randomness (prevents API patterns)
delay = 45.0 + random.uniform(0, 15.0)  # 45-60s

# Extra rest every 10 plugins
if idx % 10 == 0:
    extra_delay = random.uniform(30, 60)

Two-Phase AI Processing:

1. Analysis phase (15-20s) - Understand plugin capabilities
2. Generation phase (30-40s) - Create comprehensive SKILL.md

Quality Control:

• Minimum file size: 8,000 bytes target
• YAML frontmatter validation
• Automatic backup before modification
• SQLite audit trail for compliance
• Idempotent operations (safe to re-run)

📈 Final Metrics

🎁 What's Next

Post-Release Roadmap (10 weeks to 95% coverage):

• Weeks 1-2: High-priority 8 plugins → 71% coverage
• Weeks 3-4: API Development Wave 1 (10 plugins) → 75%
