alt Hacker NewsStarting to use Opus 4.5 I'm reduces instrutions in claude.md and just ask claude to look in the codebase to understand the patterns already in use. Going from prompts/docs to instead having code being the "truth". Show don't tell. I've found this patterns has made a huge leap with Opus 4.5.

I feel like I've been doing this since Sonnet 3.5 or Sonnet 4. I'll clone projects/modules/whatever into the working directory and tell claude to check it out. Voila, now it knows your standards and conventions.
The Ash framework takes the approach you describe.
From the docs (https://hexdocs.pm/ash/what-is-ash.html):
"Model your application's behavior first, as data, and derive everything else automatically. Ash resources center around actions that represent domain logic."
