@j178 A nit I've noticed on this one: pre-commit run my-hook-with-stage-manual will always work, but after this change I have to manually specify prek run --hook-stage manual my-hook-with-stage-manual

@ashb Interesting! I tried running pre-commit run my-hook-with-stage-manual and it didn’t work for me. I checked out the pre-commit source code here:

https://github.com/pre-commit/pre-commit/blob/72a3b71f0e7b89b78899739aeee2e962914ab649/pre_commit/commands/run.py#L423-L428

It looks like it’s filtering hooks by both hook-id and stage. Could you double-check that part?

.... You are correct. I could have sworn that worked before. I must be an AI (i.e. hallucinating)
