proj-lessons-learned

100 / 100 · Low risk

Fine to try.

By polar-bear-org/claude-skills (GitHub) · design · 54 stars · scanned at commit 95f0180

Runs a blameless lessons learned review, with what was planned against what happened and why, what to sustain and improve, and each lesson turned into an owned action or a template change. Use for "run proj-lessons-learned", "lessons learned", "project post-mortem", "after action review", "what did we learn from this project", "lessons register nobody reads", "end of phase review", part of the AI for Project Management Pack by 90n.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'proj-lessons-learned' ] || [ -L ~/.agents/skills/'proj-lessons-learned' ]; then echo 'A skill folder named proj-lessons-learned already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/polar-bear-org/claude-skills' "$d" && git -C "$d" checkout --quiet '95f01806ca43f6ee788d0579743e35853b695930' -- 'packs/ai-for-project-management-pack/skills/proj-lessons-learned' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/ai-for-project-management-pack/skills/proj-lessons-learned' ~/.agents/skills/'proj-lessons-learned' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'proj-lessons-learned' ~/.claude/skills/'proj-lessons-learned' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
