skill-finder	Find and evaluate Claude skills for specific use cases using semantic search, Anthropic best practices assessment, and fitness scoring. Use when the user asks to find skills for a particular task (e.g., "find me a skill for pitch decks"), not for generic "show all skills" requests.

Skill Finder

Find and evaluate Claude skills for your specific needs with intelligent semantic search, quality assessment, and fitness scoring.

What This Skill Does

Skill-finder is a query-driven evaluation engine that:

Searches GitHub for skills matching your specific use case
Fetches and reads actual SKILL.md content
Evaluates skills against Anthropic's best practices
Scores fitness to your exact request
Provides actionable quality assessments and recommendations

This is NOT a "show me popular skills" tool - it's a semantic matcher that finds the RIGHT skill for YOUR specific need.

When to Use

User asks to find skills for a specific purpose: "find me a skill for creating pitch decks"
User needs help choosing between similar skills
User wants quality-assessed recommendations, not just popularity rankings
User asks "what's the best skill for [specific task]"

Quick Start Examples

# Find skills for specific use case
"Find me a skill for creating pitch decks"
"What's the best skill for automated data analysis"
"Find skills that help with git commit messages"

# NOT: "Show me popular skills" (too generic)
# NOT: "List all skills" (use skill list command instead)

Core Workflow

Phase 1: Query Understanding

Extract semantic terms from user query:

User: "Find me a skill for creating pitch decks"

Extract terms:

Primary: "pitch deck", "presentation"
Secondary: "slides", "powerpoint", "keynote"
Related: "business", "template"

Phase 2: Multi-Source Search

Search Strategy:

# 1. Repository search with semantic terms
gh search repos "claude skills pitch deck OR presentation OR slides" \
  --sort stars --limit 20 --json name,stargazersCount,description,url,pushedAt,owner

# 2. Code search for SKILL.md with keywords
gh search code "pitch deck OR presentation" "filename:SKILL.md" \
  --limit 20 --json repository,path,url

# 3. Search awesome-lists separately
gh search repos "awesome-claude-skills" --sort stars --limit 5 \
  --json name,url,owner

Deduplication: Collect all unique repositories from search results.

Phase 3: Content Fetching

For each candidate skill:

# 1. Find SKILL.md location
gh api repos/OWNER/REPO/git/trees/main?recursive=1 | \
  jq -r '.tree[] | select(.path | contains("SKILL.md")) | .path'

# 2. Fetch full SKILL.md content
gh api repos/OWNER/REPO/contents/PATH/TO/SKILL.md | \
  jq -r '.content' | base64 -d > temp_skill.md

# 3. Fetch repository metadata
gh api repos/OWNER/REPO --jq '{
  stars: .stargazers_count,
  updated: .pushed_at,
  description: .description
}'

IMPORTANT: Actually READ the SKILL.md content. Don't just use metadata.

Phase 4: Quality Evaluation

Use best-practices-checklist.md to evaluate:

For each skill, assess:

Description Quality (2.0 points)
- Specific vs vague?
- Includes what + when to use?
- Third person?
Name Convention (0.5 points)
- Follows naming rules?
- Descriptive?
Conciseness (1.5 points)
- Under 500 lines?
- No fluff?
Progressive Disclosure (1.0 points)
- Uses reference files?
- Good organization?
Examples and Workflows (1.0 points)
- Has concrete examples?
- Clear workflows?
Appropriate Degree of Freedom (0.5 points)
- Matches task complexity?
Dependencies (0.5 points)
- Documented?
- Verified available?
Structure (1.0 points)
- Well organized?
- Clear sections?
Error Handling (0.5 points)
- Scripts handle errors?
- Validation loops?
Avoids Anti-Patterns (1.0 points)
- No time-sensitive info?
- Consistent terminology?
- Unix paths?
Testing (0.5 points)
- Evidence of testing?

Calculate quality_score (0-10): See best-practices-checklist.md for detailed scoring.

Phase 5: Fitness Scoring

Semantic match calculation:

# Pseudo-code for semantic matching
user_query_terms = ["pitch", "deck", "presentation"]
skill_content = read_skill_md(skill_path)

# Check occurrences of user terms in skill
matches = []
for term in user_query_terms:
    if term.lower() in skill_content.lower():
        matches.append(term)

semantic_match_score = len(matches) / len(user_query_terms) * 10

Fitness formula:

fitness_score = (
  semantic_match * 0.4 +          # How well does it solve the problem?
  quality_score * 0.3 +            # Follows best practices?
  (stars/100) * 0.2 +              # Community validation
  freshness_multiplier * 0.1       # Recent updates
)

Where:
- semantic_match: 0-10 (keyword matching in SKILL.md content)
- quality_score: 0-10 (from evaluation checklist)
- stars: repository star count
- freshness_multiplier: 0-10 based on days since update

Freshness multiplier:

days_old=$(( ($(date +%s) - $(date -j -f "%Y-%m-%dT%H:%M:%SZ" "$pushed_at" +%s)) / 86400 ))

if [ $days_old -lt 30 ]; then
  freshness_score=10
  freshness_badge="🔥"
elif [ $days_old -lt 90 ]; then
  freshness_score=7
  freshness_badge="📅"
elif [ $days_old -lt 180 ]; then
  freshness_score=5
  freshness_badge="📆"
else
  freshness_score=2
  freshness_badge="⏰"
fi

Phase 6: Awesome-List Processing

Extract skills from awesome-lists:

# For each awesome-list found
for repo in awesome_lists; do
  # Fetch README or main content
  gh api repos/$repo/readme | jq -r '.content' | base64 -d > readme.md

  # Extract GitHub links to potential skills
  grep -oE 'https://github.com/[^/]+/[^/)]+' readme.md | sort -u

  # For each linked repo, check if it contains SKILL.md
  # If yes, evaluate same as other skills
done

Display awesome-list skills separately in results for comparison.

Phase 7: Result Ranking and Display

Example Usage

See examples/sample-output.md for complete output examples.

Error Handling

No results found:

No skills found for: "[user query]"

Suggestions:
• Try broader search terms
• Check if query is too specific
• Search awesome-lists directly
• Consider creating a custom skill

Low fitness scores (all < 5.0):

⚠️  Found skills but none are a strong match.

Best partial matches:
1. [skill-name] (FITNESS: 4.2/10) - Missing [key feature]
2. [skill-name] (FITNESS: 3.8/10) - Different focus

Consider:
• Combine multiple skills
• Request skill from awesome-list curators
• Create custom skill for your specific need

GitHub API rate limit:

⚠️  GitHub API rate limit reached.

Current: 0/60 requests remaining (unauthenticated)
Resets: in 42 minutes

Solution:
export GH_TOKEN="your_github_token"

This increases limit to 5000/hour.

Performance Optimization

Parallel execution:

# Run searches in parallel
{
  gh search repos "claude skills $QUERY" > repos.json &
  gh search code "$QUERY" "filename:SKILL.md" > code.json &
  gh search repos "awesome-claude-skills" > awesome.json &
  wait
}

Caching:

# Cache skill evaluations for 1 hour
cache_file=".skill-eval-cache/$repo_owner-$repo_name.json"
if [ -f "$cache_file" ] && [ $(($(date +%s) - $(stat -f %m "$cache_file"))) -lt 3600 ]; then
  cat "$cache_file"
else
  evaluate_skill | tee "$cache_file"
fi

Quality Tiers

Based on fitness score:

9.0-10.0: Perfect match - Highly Recommended ⭐⭐⭐⭐⭐
7.0-8.9: Excellent match - Recommended ⭐⭐⭐⭐
5.0-6.9: Good match - Consider ⭐⭐⭐
3.0-4.9: Partial match - Review carefully ⭐⭐
0.0-2.9: Poor match - Not recommended ⭐

Important Notes

This is NOT:

A "show popular skills" tool
A generic ranking by stars
A list of all skills

This IS:

A query-driven semantic matcher
A quality evaluator against Anthropic best practices
A fitness scorer for your specific need
A recommendation engine

Always:

Read actual SKILL.md content (don't just use metadata)
Evaluate against best practices checklist
Score fitness to user's specific query
Explain WHY a skill fits or doesn't fit
Show quality assessment, not just stars

Remember: The goal is to find the RIGHT skill for the user's SPECIFIC need, not just show what's popular.
