Example Workflows

1. Complete Code Review Workflow

# Uses: Slash Commands + Subagents + Memory + MCP

User: /review-pr

Claude:
1. Loads project memory (coding standards)
2. Fetches PR via GitHub MCP
3. Delegates to code-reviewer subagent
4. Delegates to test-engineer subagent
5. Synthesizes findings
6. Provides comprehensive review

2. Automated Documentation

# Uses: Skills + Subagents + Memory

User: "Generate API documentation for the auth module"

Claude:
1. Loads project memory (doc standards)
2. Detects doc generation request
3. Auto-invokes doc-generator skill
4. Delegates to api-documenter subagent
5. Creates comprehensive docs with examples

3. DevOps Deployment

# Uses: Plugins + MCP + Hooks

User: /deploy production

Claude:
1. Runs pre-deploy hook (validates environment)
2. Delegates to deployment-specialist subagent
3. Executes deployment via Kubernetes MCP
4. Monitors progress
5. Runs post-deploy hook (health checks)
6. Reports status
