pre-mortem

100 / 100 · Low risk

Fine to try.

By ysskrishna/ai-agent-skills (GitHub) · coding · 23 stars · scanned at commit 8a6a574

Use for a pre-mortem, or before committing to a plan, launch or migration: "what could go wrong?", "stress test this plan", "how might this fail?", "risks before we ship". Assumes failure, lists causes, ranks them and sets mitigations. Skip for explaining a failure that already happened.

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/'pre-mortem' ] || [ -L ~/.agents/skills/'pre-mortem' ]; then echo 'A skill folder named pre-mortem already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ysskrishna/ai-agent-skills' "$d" && git -C "$d" checkout --quiet '8a6a5745556e60706ac5fa889dcc66ccd3a875b0' -- 'skills/pre-mortem' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/pre-mortem' ~/.agents/skills/'pre-mortem' && 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/'pre-mortem' ~/.claude/skills/'pre-mortem' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
