Production Bug Auto-Fix
Fixed while sleeping
The Story
A development team was facing frequent production bugs that would wake them up at odd hours. @henrymascot set up Moltbot as an autonomous bug-fixing agent integrated with their Slack alerts system. The vision was simple: let AI handle the routine bugs while developers focus on complex problems. Moltbot was trained to diagnose issues, write fixes, test them, and even create pull requests - all without human intervention.
"The bot detected a production bug and fixed it on its own. I woke up to a GitHub notification that it was already resolved."

π§ How It Works
Moltbot integrates with Sentry for error tracking, analyzes stack traces, writes fixes, runs tests, and creates PRs via GitHub integration.
1. Alert Integration
Connected Moltbot to Sentry webhooks via Slack to receive real-time production error notifications.
Configured intelligent filtering to distinguish between critical bugs and minor issues that could wait.
2. Error Analysis
When a bug is detected, Moltbot analyzes the stack trace, error logs, and recent code changes to identify the root cause.
Uses Claude's advanced reasoning to understand complex error patterns and correlate with similar historical issues.
3. Fix Generation
Moltbot writes code to fix the identified issue, following the project's coding standards and patterns.
Generates multiple potential fixes when uncertain, and tests each one to find the optimal solution.
4. Testing & Deployment
Automated tests run to verify the fix works. Once confident, Moltbot creates a PR with detailed explanation.
If tests fail, Moltbot iterates on the fix. Only working solutions are submitted for review.

workflow:
1. Analyze Sentry error report
2. Search codebase for similar patterns
3. Generate fix following project conventions
4. Run test suite
5. If tests pass, create PR with "autopilot" label
6. Notify in Slack with PR link
