Github Star Manager

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](https://github.com/settings/tokens) with `user` scope

No separate API key or environment variable is needed.

## Export Stars

```bash
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

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

## Create a List

```bash
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

```bash
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

```bash
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
