Post Mortems Retrospectives

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

Use this when you need to run a post-mortem or retrospective and want more structure than "what went wrong." It walks you through frameworks from product leaders like Annie Duke's pre-mortem kill criteria and Christina Wodtke's approach to grading OKRs for learning rather than performance. The core insight is solid: most teams either skip retrospectives entirely or turn them into blame sessions that nobody wants to repeat. This pushes you toward the right questions (what signals did we miss early, what would we do differently with the same initial information) and flags common mistakes like running reviews but never acting on them. Works for failures, successes, and routine checkpoints.

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.
