# Web Performance Optimization

Optimize website and web application performance including loading speed, Core Web Vitals, bundle size, caching strategies, and runtime performance

## When to Use
- The request matches the skill description: Optimize website and web application performance including loading speed, Core Web Vitals, bundle size, caching strategies, and runtime performance
- The task needs the implementation patterns, examples, validation checks, or edge cases listed in the topic map.
- The work would benefit from the complete guidance preserved in `references/full-guidance.md`.

## Core Workflow
1. Confirm the request matches this skill's trigger, scope, and risk profile.
2. Use the topic map to identify the relevant pattern, checklist, or example before writing detailed guidance or code.
3. Load `references/full-guidance.md` when implementation details, examples, anti-patterns, validation checks, or edge cases are needed.
4. Apply only the relevant guidance instead of loading or repeating the entire reference by default.
5. Verify the result against any validation checks, limitations, security notes, or platform constraints in the reference.

## Topic Map
- Overview
- When to Use This Skill
- How It Works
- Step 1: Measure Current Performance
- Step 2: Identify Issues
- Step 3: Prioritize Optimizations
- Step 4: Implement Optimizations
- Step 5: Verify Improvements
- Examples
- Example 1: Optimizing Core Web Vitals
- Performance Audit Results
- Current Metrics (Before Optimization)
- Issues Identified
- Optimization Plan
- Results After Optimization
- Example 2: Reducing JavaScript Bundle Size
- Bundle Size Optimization
- Current State

## Reference Map
- `references/full-guidance.md` preserves the complete original guidance, including examples and detailed edge cases.

## Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

## Progressive Loading
Keep this `SKILL.md` as the compact routing and workflow entrypoint. Load the reference file only when the user task requires the deeper implementation material.
