+# GitHub Contributor
+
+Strategic guide for becoming an effective GitHub contributor and building your open-source reputation.
+
+## The Strategy
+
+**Core insight**: Many open-source projects have room for improvement. By contributing high-quality PRs, you:
+- Build contributor reputation
+- Learn from top codebases
+- Expand professional network
+- Create public proof of skills
+
+## Contribution Types
+
+### 1. Documentation Improvements
+
+**Lowest barrier, high impact.**
+
+- Fix typos, grammar, unclear explanations
+- Add missing examples
+- Improve README structure
+- Translate documentation
+
+```
+Opportunity signals:
+- "docs", "documentation" labels
+- Issues asking "how do I..."
+- Outdated screenshots or examples
+```
+
+### 2. Code Quality Enhancements
+
+**Medium effort, demonstrates technical skill.**
+
+- Fix linter warnings
+- Add type annotations
+- Improve error messages
+- Refactor for readability
+
+```
+Opportunity signals:
+- "good first issue" label
+- "tech debt" or "refactor" labels
+- Code without tests
+```
+
+### 3. Bug Fixes
+
+**High impact, builds trust.**
+
+- Reproduce and fix reported bugs
+- Add regression tests
+- Document root cause

+description: Reviews and improves Claude Code skills against official best practices. Supports three modes - self-review (validate your own skills), external review (evaluate others' skills), and auto-PR (fork, improve, submit). Use when checking skill quality, reviewing skill repositories, or contributing improvements to open-source skills.
+---
+
+# Skill Reviewer
+
+Review and improve Claude Code skills against official best practices.
+
+## Setup (Auto-Install Dependencies)
+
+Before using this skill, ensure `skill-creator` is installed for automated validation.
+
+**Auto-install sequence:**
+
+```bash
+# 1. Check if skill-creator exists
+SKILL_CREATOR=$(find ~/.claude/plugins/cache -name "skill-creator" -type d 2>/dev/null | head -1)
+
+# 2. If not found, install it
+if [ -z "$SKILL_CREATOR" ]; then
+  claude plugin marketplace add https://github.com/daymade/claude-code-skills
+  claude plugin install skill-creator@daymade-skills
+  SKILL_CREATOR=$(find ~/.claude/plugins/cache -name "skill-creator" -type d 2>/dev/null | head -1)
+fi
+
+echo "skill-creator location: $SKILL_CREATOR"
+```
+
+## Three Modes
+
+### Mode 1: Self-Review
+
+Check your own skill before publishing.
+
+**Automated validation** (run after setup):
+
+```bash
+# Quick validation
+python3 "$SKILL_CREATOR"/*/quick_validate.py <target-skill>
+
+# Security scan
+python3 "$SKILL_CREATOR"/*/security_scan.py <target-skill> --verbose
+```
+
+**Manual evaluation**: See `references/evaluation_checklist.md`.
+
+### Mode 2: External Review
+
+Evaluate someone else's skill repository.
+
+```
+Review Workflow:
+- [ ] Clone repository to /tmp/
+- [ ] Read ALL documentation first
+- [ ] Identify author's intent
+- [ ] Run evaluation checklist
+- [ ] Generate improvement report
+```
+
+### Mode 3: Auto-PR
+
+Fork, improve, and submit PR to external skill repository.
+
+```
+Auto-PR Workflow:
+- [ ] Fork repository (gh repo fork)
+- [ ] Create feature branch
+- [ ] Apply additive improvements only
+- [ ] Self-review: respect check passed?
+- [ ] Create PR with detailed explanation
+```
+
+## Evaluation Checklist (Quick)
+
+| Category | Check | Status |
+|----------|-------|--------|
+| **Frontmatter** | name present? | |
+| | description present? | |
+| | description in third-person? | |
+| | includes trigger conditions? | |
+| **Instructions** | imperative form? | |
+| | under 500 lines? | |
+| | workflow pattern? | |
+| **Resources** | no hardcoded paths? | |
+| | scripts have error handling? | |
+
+Full checklist: `references/evaluation_checklist.md`
+
+## Core Principle: Additive Only
+
+When improving external skills, NEVER:
+- Delete existing files
+- Remove functionality
+- Change primary language
+- Rename components
+
+ALWAYS:
+- Add new capabilities
+- Preserve original content
+- Explain every change
+
+```
+❌ "Removed metadata.json (non-standard)"
+✅ "Added marketplace.json (metadata.json preserved)"
+
+❌ "Rewrote README in English"
+✅ "Added README.en.md (Chinese preserved as default)"
+```
+
+## Common Issues & Fixes
+
+### Issue: Description Not Third-Person
+
+```yaml
+# Before
+description: Browse YouTube videos and summarize them.
+
+# After
+description: Browses YouTube videos and generates summaries. Use when...
+```
+
+### Issue: Missing Trigger Conditions
+
+```yaml
+# Before
+description: Processes PDF files.
+
+# After
+description: Extracts text from PDFs. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
+```
+
+### Issue: No Workflow Pattern
+
+Add checklist for complex tasks:
+
+```markdown
+## Workflow
+
+Copy this checklist:
+
+\`\`\`
+Task Progress:
+- [ ] Step 1: ...
+- [ ] Step 2: ...
+\`\`\`
+```
+
+### Issue: Missing Marketplace Support
+
+```bash
+mkdir -p .claude-plugin
+# Create marketplace.json from template
+```
+
+See `references/marketplace_template.json`.
+
+## PR Guidelines
+
+When submitting PRs to external repos:
+
+### Tone
+
+```
+❌ "Your skill doesn't follow best practices"
+✅ "This PR aligns with best practices for better discoverability"
+
+❌ "Fixed the incorrect description"
+✅ "Improved description with trigger conditions"
+```
+
+### Required Sections
+
+1. **Summary** - What this PR does
+2. **What's NOT Changed** - Show respect for original
+3. **Rationale** - Why each change helps
+4. **Test Plan** - How to verify
+
+Template: `references/pr_template.md`
+
+## Self-Review Checklist
+
+Before submitting any PR:
+
+```
+Respect Check:
+- [ ] No files deleted?
+- [ ] No functionality removed?
+- [ ] Original language preserved?
+- [ ] Author's design decisions respected?
+- [ ] All changes are additive?
+- [ ] PR explains the "why"?
+```
