I use Claude code with Elixir and Phoenix. It's been mostly great but after a short time into a project it seems to break something unrelated to the task at hand.

If you haven’t yet, you should try out usage_rules mix package. I mostly use Ash, which has great support for usage rules and it’s a night and day difference in effectiveness. Tidewave is also really nice as an MCP as it lets the agent query hexdocs or your schema directly.

Thank you! I'll definitely check that out.

Also check out the AGENTS.MD file that's been added to Phoenix 1.8.

Make sure you read it first though... I believe it expected Req to be present as a dependency when generating code that makes HTTP requests.
