name	github-star-manager
description	Manage GitHub stars with AI-powered categorization and cleanup. Use when a user wants to organize their starred repos into GitHub Lists, clean up stale/deprecated stars, export star data for analysis, or get stats about their GitHub stars. Supports semantic categorization via LLM and bulk operations (unstar, add-to-list).

GitHub Star Manager

Requires gh (authenticated) + jq. For Lists operations: token needs user scope (Classic token recommended).

Authentication

This skill uses the gh CLI's existing auth session. Before using:

1. Run gh auth login if not already authenticated
2. For read-only operations (export, stats): default token scopes are sufficient
3. For Lists operations (create list, add to list): token needs user scope — run gh auth refresh -s user or use a Classic token with user scope

No separate API key or environment variable is needed.

Export Stars

gh api user/starred --paginate --jq '.[] | {
  full_name, description, url: .html_url, language,
  topics, stars: .stargazers_count, forks: .forks_count,
  archived, updated_at, pushed_at
}' | jq -s '.' > stars.json

Slow for 1000+ stars (~1 min per 1000). Quick count: gh api user/starred --paginate --jq '. | length' | jq -s 'add'.

View Existing Lists

gh api graphql -f query='{
  viewer {
    lists(first: 100) {
      nodes { id name description isPrivate items { totalCount } }
    }
  }
}' --jq '.data.viewer.lists.nodes'

Create a List

gh api graphql -f query='
mutation($name: String!, $desc: String) {
  createUserList(input: {name: $name, description: $desc, isPrivate: false}) {
    list { id name }
  }
}' -f name="LIST_NAME" -f desc="LIST_DESCRIPTION" --jq '.data.createUserList.list'

Save the returned id for adding repos.

Add Repo to List

REPO_ID=$(gh api repos/OWNER/REPO --jq '.node_id')

# Note: listIds is a JSON array, use --input to pass variables correctly
echo '{"query":"mutation($itemId:ID!,$listIds:[ID!]!){updateUserListsForItem(input:{itemId:$itemId,listIds:$listIds}){user{login}}}","variables":{"itemId":"'$REPO_ID'","listIds":["LIST_ID"]}}' \
  | gh api graphql --input -

Add ~300ms delay between calls to avoid rate limits.

Unstar

gh api -X DELETE user/starred/OWNER/REPO

Always confirm with user before unstarring.

Organize Workflow

1. Export stars to JSON
2. Analyze the JSON — suggest categories based on language, topics, purpose, domain
3. Present suggestions to user for review
4. Create Lists and add repos after confirmation
5. Batch operations with delays between API calls

Cleanup Workflow

1. Export stars to JSON
2. Use jq to find archived, stale (2+ years no push), low-star, or deprecated repos
3. Present candidates to user, confirm before unstarring
