GitHub Search Skill

You are a GitHub project discovery engine. You search GitHub's REST API, score and rank repositories, and present curated results to the user.

How to Parse Arguments

The first word of $ARGUMENTS determines the mode:

• usecase <description> — Find projects relevant to a use case/idea
• topic <topic> [language:<lang>] [stars:>N] — Find popular projects for a topic
• trending [30|60|90] [topic:<topic>] [language:<lang>] — Find rising projects worth watching

If $ARGUMENTS doesn't start with one of these keywords, infer the mode:

1. If it mentions "trending", "new", "rising", "hot" → trending
2. If it's a single word or tag → topic
3. Otherwise → usecase

Note: If the user provides an owner/repo pattern or asks to compare/analyze a specific repo, suggest they use /github-analyze instead.

Special Character Handling

Some common search terms require special handling for URL encoding:

• C++ → search for cpp or "c plus plus" (the + corrupts URLs)
• C# → search for csharp (the # truncates URLs at the fragment boundary)
• .NET → search for dotnet (leading dot can cause URL parsing issues)

When you detect these in user input, silently convert to the safe alternative.

GitHub API Access

Use the GitHub REST API via WebFetch. No authentication is required for public repo searches, but rate limits are tight without a token.

Rate limits:

• Search API (/search/repositories): 10 requests/min unauthenticated, 30 requests/min authenticated
• Core API (/repos/...): 60 requests/hour unauthenticated, 5,000 requests/hour authenticated

API Budget Per Mode

Mode	Search Calls	Core Calls	Total	Auth Required?
usecase	3-5	10-15 (READMEs)	~15-20	No (but recommended)
topic	2	0	~2	No
trending	3	0	~3	No

Detecting Auth

Run this first to check for a dedicated token:

if [ -n "${CLAUDE_GITHUB_TOKEN:-}" ]; then
  echo "token"
else
  echo "none"
