Description: Type checkers catch missing enum cases in if/elif chains via assert_never, but cannot catch missing keys in enum-keyed dicts. A new agent skill codifies this pattern, and a test is added for the existing _STATUS_TO_CLASSIFIER_MAP. New skill (.agents/skills/usethis-python-enum/SKILL.md): Documents two enum conventions — assert_never for exhaustive branching, and mandatory unit tests for dicts with enum keys New test (TestStatusToClassifierMap.test_keys_match_enum): Asserts _STATUS_TO_CLASSIFIER_MAP keys exactly match DevelopmentStatusEnum members class TestStatusToClassifierMap: def test_keys_match_enum(self): assert set(_STATUS_TO_CLASSIFIER_MAP.keys()) == set(DevelopmentStatusEnum) Original prompt This section details on the original issue you should resolve Configure agent skills to encourage appropriate style when working with enums Probably a new skill called usethis-python-enum Originally encountered here: @copilot Please add a unit test that checks this dict is comprehensive, i.e. its keys are the same as the enum elements Originally posted by @nathanjmcdougall in #1469 (comment) Type checkers will capture a lot of patterns if we are careful. The assert_never pattern used in the codebase, etc. There's this particular example of a dict with an enum key, which deserves a dedicated unit test to ensure it's kept updated to ensure complete coverage over the enum Comments on the Issue (you are @copilot in this section) Fixes #1479 📱 Kick off Copilot coding agent tasks wherever you are with GitHub Mobile, available on iOS and Android.
