Let an AI Agent Debug for 200 Minutes While You Focus on Customers

One-Click, Hands-Off Debugging

Replit just dropped Agent 3, a coding agent that keeps iterating for ≈200 minutes until your tests go green—Amjad Masad (@amasad) calls it the "Full Self-Driving moment of software." Tweet →

How to try it (≈5 min setup)

Fork your repo on Replit. Free tier works for small projects.
Click "Run with Agent 3." It reads your code, runs tests, and loops on fixes.
Set guardrails: max runtime, file paths it can touch, & auto-commit off (so you review before merge).

Why it matters

• Saves the 80/20 bug-hunt grind—Agent 3 handles edge-case errors while you work on users & sales.
• Outputs a diff + test log so you keep control.
• Works on legacy code; just add—or auto-generate—tests first.

Pro-tip: Layer an agentic test writer (Claude Code or Gemini CLI) to auto-create tests before you unleash Agent 3.

How to run this with CodeBrain (privacy-first, ~400 chars)

Clone repo into your Obsidian vault (Google Drive-synced).
In Claude Code CLI: write tests for src/**.
Trigger Rube MCP → Replit → Agent 3. It pushes code, waits out the 200 min loop, then pulls the diff back into your vault for review.
Commit only the chunks you approve—your IP never leaves your private vault.

Ship faster, keep ownership.
