/em:postmortem — Honest analysis of what went wrong. Use after a failed launch, missed quarter, or bad hire to run a blameless 5-Whys retrospective with a change register — e.g. dissecting why the Q3 release slipped six weeks.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'postmortem' ] || [ -L ~/.agents/skills/'postmortem' ]; then echo 'A skill folder named postmortem already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/sinhoneyy/master-skills' "$d" && git -C "$d" checkout --quiet '8e70b780359915a1f197ca37a1add2d4016115a2' -- 'skills/postmortem' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/postmortem' ~/.agents/skills/'postmortem' && 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/'postmortem' ~/.claude/skills/'postmortem' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
