github-browse

name: github-browse description: Open a GitHub issue or PR in browser and optionally manage subscriptions. Use when navigating to GitHub resources from the terminal. argument-hint: [issue-or-pr-number] [sub|un] disable-model-invocation: true

Open a GitHub issue or pull request in the browser using gh issue view --web or gh pr view --web. Optionally subscribe or unsubscribe from notifications for the issue/PR.

Requirements:

• If user provides $1 (issue or PR number), use that value
• Otherwise, extract the most recently discussed issue or PR number from the conversation context
• Determine the appropriate repository using one of:
  1. Current git repository (if in a git repo): git remote get-url origin
  2. If the issue/PR was discussed with a full org/repo reference, use that
  3. Default to anthropics/claude-code if the context suggests Claude Code issues
• Use gh issue view <number> -R <org/repo> --web for issues
• Use gh pr view <number> -R <org/repo> --web for PRs
• If unclear whether it's an issue or PR, try issue first (gh will auto-detect)

Subscription management (optional):

• If $2 is "sub", subscribe to notifications for this issue/PR
• If $2 is "un", unsubscribe from notifications for this issue/PR
• If $2 is blank/not provided, do not perform any subscription action
• Subscription requires the notifications scope in your gh token
  • If not present, run: gh auth refresh -h github.com -s notifications
• Uses GraphQL API to get the issue/PR ID and update subscription state

Implementation approach:

1. Extract issue/PR number from $1 or conversation context
2. Determine the repository (current repo, or from context, or claude-code default)
3. Execute: gh issue view <number> -R <org/repo> --web
4. If $2 is "sub" or "un": a. Query GraphQL to get the issue/PR's subscribableId b. Execute updateSubscription mutation with appropriate state (SUBSCRIBED for "sub", UNSUBSCRIBED for "un") c. Handle both issues and PRs (query should check both types)
5. The gh CLI will automatically open the URL in the default browser

Examples:

• /github:browse 8677 - Opens issue #8677 in the current/contextual repo
• /github:browse 8677 sub - Opens issue #8677 and subscribes to notifications
• /github:browse 8677 un - Opens issue #8677 and unsubscribes from notifications
• /github:browse - Extracts and opens the most recently discussed issue/PR number

Note: The gh CLI intelligently handles both issues and PRs with the same command when using gh issue view, so we can use that for both types.
