## Summary

Sophia Yang shares a talk by @poteto on how the Grok Bot team shipped 11,000 PRs last month without quality dropping. The talk says reliable agents depend on clean code and surrounding checks more than better prompts. It also reports about one stable release a day, 227 contributors in October, and a ~0.5% revert rate.

## Why it matters

The talk gives concrete practices for keeping agent-written code reliable, such as turning corrections into deterministic checks and banning patterns that need nuance.

Great talk from @poteto on how the Grok Bot team shipped 11,000 PRs last month without the quality dropping:
• Reliable agents come from the codebase and checks around them, not from better prompts. Most effort goes to clean code and architecture, then lint/types/tests/verification, then a little prose in AGENTS.md.
• Every time you correct an agent, turn the correction into a deterministic check instead of another rule in markdown.
• Agents copy whatever's already in your codebase, so tech debt and workarounds spread fast. Keep it clean.
• Ban patterns that need nuance to use well. They banned useEffect in product code and about 99% of code comments, since agents use comments to justify shortcuts.
• Code review turns into reviewing proof: videos, screenshots, diagrams, and formal checks.
• Agents make thorough verification affordable. Most of her tokens now go to it: runtime checks, TLA+ for user flows, Lean for algorithms, property-based tests for UI.
• Fix the inner loop before you build a "software factory." Automating sloppy output just gets you more of it, faster.
• Their results: about one stable release a day, 227 contributors in October, a ~0.5% revert rate, and an app that got faster.
