Included Skills3

code-commentsskills/code-comments/SKILL.md

Rules for when a code comment earns its place. Use whenever writing new code, reviewing a diff, or deciding whether to keep, cut, or rewrite a comment — including docstrings and doc comments. Triggers on writing functions, reviewing PRs, "should I comment this", "add a docstring", or any comment already present in a diff under review.

test-strategyskills/test-strategy/SKILL.md

Deciding what deserves a test, what kind (unit/integration/e2e), and when to write it — as distinct from how to write a good test (see writing-tests). Use when planning test coverage for new code, reviewing a PR for missing or excessive tests, or choosing between a unit, integration, or end-to-end test. Triggers on: "does this need a test", "what should I test here", "unit or integration test", "test coverage", "add tests for this PR", sizing a test suite, or a PR that changes behavior without a corresponding test.

unslopskills/unslop/SKILL.md

Cut AI tells from any writing. Must always apply.
