Backend Patterns

Generally-applicable best practices for backend/data work. Read every pattern below. If any matches what you're about to build, apply it. Don't ask permission for things that are codified here — just follow the rule and note in one line that you did.

When to consult this skill

Any time you are writing or editing code that:

• Saves, inserts, or persists a URL/link to a database
• Accepts a link from a user, agent, webhook, import, or paste handler
• Forwards a link to another system
• Adds a link to any knowledge-keeping surface (e.g. Kanban, Task Console, Knowledge Base, bookmarks, notes)
• Builds an agent tool that creates records containing links
• Queries or writes to the database (reads, inserts, updates, deletes)
• Changes the database schema, or runs migration/generate/push commands

If none of the patterns below match the scenario, return to the original task without comment.
