# Claude Code handles daily maintenance at Anthropic, 46% merge rate

*2026-08-14 · Source: [The Decoder](https://the-decoder.com/claude-code-now-runs-daily-maintenance-on-anthropics-software-with-a-46-percent-merge-rate/)*

Anthropic is testing Claude Code for daily maintenance of its own software, including crash fuzzing and dead-code removal, according to The Decoder. Over a few weeks the AI created 388 pull requests, with 46% merged after human review.

**Why it matters:** A 46% human-approved merge rate on autonomously generated maintenance PRs is a concrete, measurable data point for agentic coding reliability, moving the conversation from benchmark scores to actual production usage and signaling Anthropic's confidence in deploying its own agents on its own codebase.
