- goal-testundefined-ui/second-brain-osTurn a vague task into a testable definition of done and generate an executable goal-test script for it, optionally with a bounded retry loop around a headless agent. Use when the user wants to run an agent in a loop, asks how to know when an agent task is finished, or says a goal like "improve X" needs to become checkable. Do NOT use for building eval suites over many cases — that is evals-bootstrap.TestingNo warnings★ 1.3K↓ —
- band-agreementmohitagw15856/pm-claude-skillsWrite the band agreement before the money or the breakup arrives — who owns the songs, how money splits (writing vs performing distinguished), who owns the name, what happens when someone quits, and the decision rules for offers — decided while everyone still shares a van. Use when a band asks 'how should we split money', 'who owns our songs', 'our drummer quit, what happens', or is about to record/release/sign anything.
