When to use

Use this skill when implementing or changing API endpoints, handlers, middleware, domain logic, or backend data access in apps/api.

Goal

Add or modify backend functionality while keeping handlers thin, validation explicit, and database access separated from HTTP concerns.

Preconditions

Read AGENTS.md
Read obsidian-vault/03 Backend/Go Project Structure.md
Read obsidian-vault/03 Backend/Validation Rules.md
Read obsidian-vault/02 Architecture/API Design.md

Workflow

Identify the domain area affected: auth, posts, projects, tags, or messages.
Define request and response shapes before implementation.
Add validation at the API boundary.
Keep transport concerns separate from business and data access concerns.

01When to use 02

Implement the minimal domain logic required.

Add or update database access carefully.

Run the smallest relevant test scope first.

Broaden validation only when the change is structural.

Update docs if endpoint contracts or architecture changed.

Backend rules

Prefer explicit structs over generic maps.
Fail fast on startup configuration errors.
Return predictable JSON errors.
Do not leak internal details in HTTP responses.
Group logic by domain.
Avoid unnecessary interfaces before they are justified.

Validation checklist

inputs are validated
handler behavior matches API design
error shape is predictable
database changes use migrations if schema changed
smallest relevant tests or checks pass

Common mistakes

putting business logic directly in handlers
trusting frontend input without validation
returning raw database errors to clients
adding extra layers with no payoff

Done criteria

The backend change is domain-focused, validated, and aligned with the planned API style.
