We split this skill into the rules it gives an agent

8 rules. About 0 are common, 6 are distinctive, and 2 are very specific to this project.

• ≈0

  Common · estimate

  Many files like this have a rule of this kind.

• ≈6

  Distinctive · estimate

  This author's own choices. Worth a look.

• 2

  Very specific

  Tied to their project's names, files or tools. Probably skip.

1. Very specific:

   Run codemap --importers <file> to see all dependents

   line 12
2. Distinctive:

   Check if tests exist for dependents, not just the hub itself

   line 14
3. Distinctive:

   Prefer additive changes over breaking changes

   line 18
4. Distinctive:

   If renaming or removing a public symbol, update all importers in the same commit

   line 19
5. Distinctive:

   If changing a function signature, check all call sites

   line 20
6. Distinctive:

   Run the full test suite, not just the hub's tests

   line 24
7. Very specific:

   Run codemap --deps . to verify the dependency graph is intact

   line 25
8. Distinctive:

   If the hub has 8+ importers, consider a staged rollout (change hub, test, update callers separately)

   line 26

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill 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.
