Do not use when/for TDD process discipline alone (use tdd-workflow) or load testing (use performance-testing).

jagreehal Bundle

Chooses test pyramid layers, what to mock, and where tests live for fn(args, deps) systems. Use this skill when deciding unit vs integration vs e2e coverage or structuring a test approach for a feature. Do not use when/for the red-green-refactor loop itself (use tdd-workflow) or writing individual test cases (use writing-tests).

mjunaidca Bundle

Diagnose and fix Hypothesis (hypothes.is) annotation visibility — why two people in the same group see different annotation counts, why a class or study group can't see someone's notes, why highlights never show up for anyone else, and how to safely move "Only Me" annotations into a group or pull accidentally-public ones back out. Use this whenever someone mentions Hypothesis, hypothes.is, web annotations, annotation groups, highlights that aren't appearing, mismatched annotation counts ("I see 5, they see 149"), students who can't see the teacher's notes, or annotations that went public by mistake — including when they describe it as a broken integration, a sync issue, a caching problem, or a membership/permissions bug, because it is almost never any of those.
