Individual skill
backend
Design, change, debug, or inspect server-side behavior when an API, database, authentication or authorization path, background job, webhook, external dependency, migration, cache, concurrency invariant, or production reliability concern is in scope. Use this skill for backend work in any stack; inspect the repository before choosing framework-specific patterns.

# backend: server-side engineering without framework cosplay
Build backend behavior that stays correct when requests duplicate, users race,
dependencies fail, schemas evolve, and operators need to understand an incident.
The deliverable is not merely code that returns the happy-path response. It is a
verified contract, with its data, security, recovery, and operational behavior
made explicit.
## Purpose and boundaries
Use this skill when a task changes or evaluates any of these surfaces:
- HTTP, RPC, GraphQL, CLI, webhook, queue, cron, or agent-tool boundary;
- persistent data, migrations, indexes, transactions, or consistency rules;
