Disclaimer: I am a Co-Founder of Armature (YC P26) which sells growth services to dev tools. This study is part of our broader work on how to influence coding agents choices and get products picked.
To understand how agents pick tools we measured close to 17k sessions on an environment where agents run exactly like in the real world, on various repositories, talking to different personas (vibe-coder, junior or senior engineers) in different sizes of companies.
All the results are now public and we'd love to know what findings surprise you the most, here are a few we found interesting:
- Claude Code rarely searches the web while Codex almost always does it and Cursor sits in the middle.
- Coding agents disagree more frequently than they agree.
- Some players (LangChain, Supabase, Netlify, Paypal, Adyen) are almost always mentioned in their categories but never chosen.
- Modifying repository context can change the pick entirely.
If you feel like digging, all the traces are there and we probably missed interesting learnings so let us know what you find!
