For something like tests, where I have very specific opinions on how I want them written, I have a simple doc (tests.md) and I’ll regularly tag Claude with it.

Claude writes a bunch of new code and I’ll tell it, “Before I review this code, make sure all tests adhere to the guidance of @tests.md” (you can probably make this a slash command too)

I find that if I put these instructions in the system prompt, far down in a conversation that’s used lots of the context window, they will only loosely be followed. But when I tag it in like this, Claude will strongly and thoughtfully follow the guidance and examples I’ve written up about how I want my tests.
