Managing Timelines

refoundai/lenny-skills
1.6k installs1.2k stars
Summary

I've used this when stakeholders ask "when will it ship?" and I need to give an answer that won't haunt me three months later. The skill walks you through diagnosing whether you have an estimation problem, a scoping problem, or just unrealistic expectations, then applies frameworks from product leaders like using hill charts to visualize uncertainty or committing to discovery phases instead of distant delivery dates. The best part is the "ship early, iterate with remaining time" approach, which feels backwards but actually works. It's opinionated about treating real deadlines as P0 and ruthlessly protecting focus, which might not fit every team culture but makes the advice concrete enough to actually use.

steve-jobs-design-review

wondelai/skills

Review designs, products, and features with Steve Jobs' standards: ruthless simplicity, focus, and end-to-end excellence. Use when the user mentions "Steve Jobs review", "design review", "product review", "what would Steve do", "insanely great", "this feels too complicated", "too many features", "product taste", "saying no", or "is this good enough to ship". Also trigger when critiquing a UI, feature, or roadmap for focus and simplicity, cutting scope to the essential, or pressure-testing the whole experience from first run to daily use. Covers the simplicity audit, the no list, design-is-how-it-works, end-to-end ownership, demo culture, and a Jobs-style review protocol with binary verdicts. For visual design fundamentals, see refactoring-ui. For usability audits, see ux-heuristics. For detail polish, see microinteractions.
