description	Query Serena memories for relevant learnings before ANY significant work including bug investigation, feature implementation, API changes, or architecture decisions. Use when starting work to leverage existing knowledge and avoid repeating past mistakes. Use when this capability is needed.

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

Quick Reference: Top 10 Rules

#	Rule	Memory
1	POST body, not query params	api-design-patterns-master
2	Never nest transactions	database-transaction-patterns-master
3	snake_case everywhere	api-design-patterns-master
4	Docker-first development	docker-devops-patterns-master
5	Never downgrade DB versions	docker-devops-patterns-master
6	Check for override files	docker-devops-patterns-master
7	Explicit waits in tests	testing-patterns-master
8	Pre-commit before commit	testing-patterns-master
9	Fix root causes, not symptoms	code-quality-patterns-master
10	Idempotent event handlers	event-driven-patterns-master
