Kill the plan on paper before reality does it for money. Use when a plan, launch, migration, or strategy is about to be committed to and nobody has tried hard to murder it yet — the assassin attacks through twelve named failure vectors and writes the post-mortem of the failure that hasn't happened. Produces a premortem: the death narrative, the twelve-vector attack with survival verdicts, the three kill-shots most likely to land, and the cheap tripwires that would give early warning.

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/'premortem-assassin' ] || [ -L ~/.agents/skills/'premortem-assassin' ]; then echo 'A skill folder named premortem-assassin already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mohitagw15856/pm-claude-skills' "$d" && git -C "$d" checkout --quiet 'edb6995427bac9d948775258a82aeecced60ceb1' -- 'skills/premortem-assassin' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/premortem-assassin' ~/.agents/skills/'premortem-assassin' && 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/'premortem-assassin' ~/.claude/skills/'premortem-assassin' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
