- labhashgraph-online/awesome-codex-pluginsBuild a Game Lab for one mechanic of a studio's game (the jump, a hit, a dash, a drift, a landing) and iterate on how it FEELS with the creator, side by side. The lab plays one short take in two builds at once, New (the working tree) and Today (the last commit), on one clock with the same seed and presses, slowed to a tenth or stepped a frame at a time, with a timeline of named phases, graphs of tracked values New against Today, the game's own onion skins and arcs, preset views, a phone-size view, and live sliders that write kept values back into the game's tunables.json.

TestingUpdated yesterday
From the author
Test quality review drawing on twelve classic engineering books — with primary focus on xUnit Test Patterns, The Art of Unit Testing, How Google Tests Software, and Working Effectively with Legacy Code — that diagnoses structural problems in an existing test suite: brittleness, mock abuse, coverage illusions, slow execution, poor readability. Triggers when: user asks about test quality, shares test files for review, or expresses frustration: "tests keep breaking whenever I change anything", "our tests take forever", "tests pass but bugs still reach production", or "we have too many mocks". Do NOT trigger for: writing new tests from scratch (use the regular test-writing workflow) or testing framework/syntax questions — this skill reviews an existing suite for structural quality problems, not individual test authoring.
