Problem Definition

refoundai/lenny-skills
1.8k installs1.2k stars
Summary

This helps you articulate problems before building solutions, which is harder than it sounds when you're excited about a feature idea. It pushes you to separate the struggling moment from your proposed fix, distinguish business problems from customer problems, and avoid the "let's use AI because it's cool" trap. Built from frameworks by 91 product leaders like Marty Cagan and Bob Moesta. Use it when scoping new features, validating product ideas, or catching yourself solution-first. The questioning approach is genuinely useful for getting unstuck when you know something feels off but can't articulate why.

improve

shadcn/improve

Survey any codebase as a senior advisor and produce prioritized, self-contained implementation plans for OTHER models/agents to execute. Strictly read-only on source code — never implements, fixes, or refactors anything itself. Use when asked to audit a codebase, find improvement opportunities (bugs, security, performance, test coverage, tech debt, migrations, DX), suggest features or where to take the project next (roadmap, product direction), or generate handoff plans for another agent to implement.
