| description | Framework-agnostic frontend architecture — state management, components, data fetching. Use when building any web frontend, choosing state patterns, or structuring UI code. |

Principles
- Start with local state — lift only when shared
- Organize code by feature, not by type
- Use named exports for better refactoring and searchability
- Never use barrel files (index.ts re-exports) — they break tree-shaking and slow builds
- Measure before memoizing — don't optimize what isn't slow
Rules
See rules index for detailed patterns.
Examples
Positive Trigger
User: "Choose state boundaries and data-fetching patterns for this web app."
Expected behavior: Use platform-frontend guidance, follow its workflow, and return actionable output.
Non-Trigger
User: "Write a Swift actor for thread-safe cache access."
Expected behavior: Do not prioritize platform-frontend; 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
- Identify whether the request clearly matches
platform-frontend scope and triggers.
- Apply the skill rules and referenced guidance to produce a concrete result.
- Validate output quality against constraints; if gaps remain, refine once with explicit assumptions.
