1. Distinctive:

   Read README.md for a description of the tests.

   line 3
2. Distinctive:

   Prefer blackbox tests written in cram over unit tests.

   line 7
3. Distinctive:

   Only write unit tests for parts of the code that does not require mocking

   line 11
4. Very specific:

   Instead of adding a For_tests module, consider writing the test right in the library using ppx_expect.

   line 13

≈ “Common” is an estimate: at least 1 in 5 of the 36,368 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

• Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.

  Of the AGENTS.md files we read, the 28,693 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
