Use when an outage, production incident, or significant service degradation has occurred and the team needs a blameless post-mortem / RCA document in the Google SRE format. Triggers on phrases like "write a post-mortem", "incident review", "what went wrong", "outage report", "root cause analysis", "RCA", or "fishbone". Collects incident inputs from the user, uses a fishbone (Ishikawa) diagram to surface candidate causes, drills the strongest branches with 5 Whys, and produces typed action items…

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/'incident-postmortem' ] || [ -L ~/.agents/skills/'incident-postmortem' ]; then echo 'A skill folder named incident-postmortem already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/github/awesome-copilot' "$d" && git -C "$d" checkout --quiet '227949a7542a55d2155c00e7cdb998d9a0fee4f3' -- 'skills/incident-postmortem' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/incident-postmortem' ~/.agents/skills/'incident-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/'incident-postmortem' ~/.claude/skills/'incident-postmortem' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
