Claude Code Routines Tunes CLI Performance 2.4x in 20+ PRs
Claude Code's Routines feature can be used for continuous autonomous optimization. A developer (u/yamadashy) set it up on a 2-hour cron schedule to tune their open-source CLI tool Repomix. Over 20+ PRs, the runtime improved by 2.4x.
Key Components
- Automated Tuning via Routines: A prompt defines performance goals; Claude Code's Routines run every 2 hours, generates changes and opens PRs.
- Benchmark Workflow (GitHub Actions): A custom workflow runs multi-OS measurements to validate each AI-suggested change before merging.
- Merge Flow: AI suggestions are picked up and merged into main after passing benchmarks.
The exact prompt used is shared in the article, along with all configuration files. Everything is open source — no paid tiers required. Repomix is the CLI that was optimized; Claude Code Routines and the benchmark workflow are also free to try.
For developers using AI coding agents, this demonstrates a practical CI loop: let AI continuously propose optimizations, validate against real benchmarks, and merge only improvements.
