📊 Summary

Main branch: ${\n mainCommits.data.length\n } commits in last 30 days

Release branch: ${\n releaseCommits.data.length\n } commits in last 30 days

Commits only in main: ${\n mainOnlyCommits.length\n }

Commits only in release: ${\n releaseOnlyCommits.length\n }

\n\n ${\n mainOnlyCommits.length > 0\n ? `\n

⚠️ Warning

There are ${mainOnlyCommits.length} commits in the main branch that are NOT in the release branch. \n This means your current configuration (monitoring release branch) is missing recent updates.

💡 Recommendations

• If you want to track all development activity, monitor the main branch
• If you only want to track official releases, keep monitoring the release branch
• If you want both, you can monitor both branches (they'll be labeled in the Discord messages)

It categorizes commits based on [conventional commit messages](https://www.conventionalcommits.org/en/v1.0.0/) ie. `feat:`, `fix:` etc., and uses AI to generate user-friendly summaries.\n\n**Example:**\n![Screenshot 2025-05-24 at 6.12.40 PM.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/112a693d-7482-42d8-171c-be2bf916cf00/public)\n\n### Configuration\n\n#### Repository Setup\n\nThe repositories to monitor are configured directly in the code in `process-commits.tsx`. Update the `REPOS` array to add or modify repositories:\n\n```typescript\nconst REPOS = [\n { owner: \"steel-dev\", name: \"steel-browser\", branch: \"main\" },\n { owner: \"steel-dev\", name: \"steel-api\", branch: \"develop\" },\n { owner: \"steel-dev\", name: \"steel-docs\", branch: \"main\" },\n];\n```\n\nEach repo configuration includes:\n\n- `owner`: GitHub repository owner/organization\n- `name`: Repository name\n- `branch`: Specific branch to monitor (e.g., \"main\", \"develop\", \"staging\")\n\n#### Environment Variables\n\nBefore you can run the cron or try out the playground, you must add the following Environment Variables (via left sidebar of this val):\n\n- `GITHUB_TOKEN`:\n - **For public repos, or personal repos:** Go to [GitHub Personal Access Tokens](https://github.com/settings/tokens) → Generate new token (classic) → Select `repo` scope\n - **For org-owned repos:** Go to [GitHub Personal Access Tokens](https://github.com/settings/tokens) → Resource Owner → Select the org the repo belongs to → read access to `Contents`. You will need approval from the org admin.\n- `DISCORD_WEBHOOK_URL`: In your Discord server → Server Settings → Integrations → Webhooks → New Webhook → Copy Webhook URL\n\n### How to use\n\n- **`gh-to-discord.tsx`** is a cron that runs automatically based on your configured schedule, fetching commits since the last run\n\n- **`playground.tsx`**\n You can also manually test this val using the `playground.tsx` HTTP endpoint.\n\n_Here's an [Example Playground with the `steel` repo](https://test-gh-to-discord.val.run/).\n![](https://filedumpthing.val.run/blob?key=blob_file_1748033253538_Google%20Chrome.gif)_\n\n## Key Features\n\n### Multi-Repository Support\n\n- Monitor multiple repositories simultaneously\n- Support for different branches per repository\n- Single unified changelog combining all repositories\n- Each commit shows which repository it came from: `[repo-name] commit message`\n\n### Commit Categorization\n\nThe bot automatically categorizes commits into the following sections (feel free to add more!):\n\n- ✨ **New Features** (`feat:`)\n- 🐛 **Bug Fixes** (`fix:`)\n- ⚙️ **Chores & Maintenance** (`chore:`)\n- 📋 **Other Updates** (uncategorized commits)\n\n## Customizing AI Summaries\n\nEach commit message is processed by GPT to generate a more user-friendly message.\n\nYou can modify the GPT prompt in the `generateUserFocusedSummary()` function in `process-commits.tsx`. You can paste in examples of past changelogs to help the LLM understand your desired
