Check Serena Learnings

Check Serena Learnings Before Work

When to Use This Skill

• Before investigating ANY bug or issue
• Before implementing new collectors or processors
• Before modifying event schemas or RabbitMQ configuration
• Before API endpoint changes (remember: POST body, not query params!)
• Before database migrations or transaction handling
• Before Docker/deployment changes
• Before architecture decisions
• When encountering errors you've never seen before
• When stuck on a problem for more than 10 minutes

Step-by-Step Process

Step 1: List Available Memories

mcp__serena__list_memories()

Step 2: Identify Relevant Memories by Keywords

For Bug Investigation:

• Search memories containing: bug, fix, error, issue

For API Work:

• Read: api-design-patterns-master.md
• Key lesson: POST/PUT/DELETE use request body, NEVER query params

For Database/Transaction Work:

• Read: database-transaction-patterns-master.md
• Key lesson: NEVER nest transactions

For Event-Driven Work:

• Read: event-driven-patterns-master.md
• Key lesson: Handlers MUST be idempotent

For Docker/DevOps:

• Read: docker-devops-patterns-master.md
• Key lesson: Never downgrade DB versions

For Testing:

• Read: testing-patterns-master.md
• Key lesson: Explicit waits, never arbitrary timeouts

Step 3: Read Relevant Memories

mcp__serena__read_memory(name="api-design-patterns-master")

Step 4: Apply Learnings

Before proceeding with your task, explicitly state:

1. Which memories you checked
2. Which patterns apply to your current work
3. Which anti-patterns you will avoid
