platform-backend

name	platform-backend
description	Server-side architecture and security — API design, error handling, validation, logging. Use when building APIs, server logic, or reviewing backend security.

Principles

• Throw early with guard clauses — fail fast at the top of functions
• Never swallow errors silently — log or propagate every failure

Rules

See rules index for detailed patterns.

Examples

Positive Trigger

User: "Design error handling and validation strategy for this API endpoint."

Expected behavior: Use platform-backend guidance, follow its workflow, and return actionable output.

Non-Trigger

User: "Create a Tailwind design token scale."

Expected behavior: Do not prioritize platform-backend; choose a more relevant skill or proceed without it.

Troubleshooting

Skill Does Not Trigger

• Error: The skill is not selected when expected.
• Cause: Request wording does not clearly match the description trigger conditions.
• Solution: Rephrase with explicit domain/task keywords from the description and retry.

Guidance Conflicts With Another Skill

• Error: Instructions from multiple skills conflict in one task.
• Cause: Overlapping scope across loaded skills.
• Solution: State which skill is authoritative for the current step and apply that workflow first.

Output Is Too Generic

• Error: Result lacks concrete, actionable detail.
• Cause: Task input omitted context, constraints, or target format.
• Solution: Add specific constraints (environment, scope, format, success criteria) and rerun.

Workflow

1. Identify whether the request clearly matches platform-backend scope and triggers.
2. Apply the skill rules and referenced guidance to produce a concrete result.
3. Validate output quality against constraints; if gaps remain, refine once with explicit assumptions.
