Pre Motion B1rdmania

Category: Security  ·  Sub-category: forensics  ·  Last updated:
Runs an adversarial premortem on a UK litigation matter. Builds the strongest version of the case, then attacks it from four angles — procedural, substantive, evidentiary, strategic — to find where it actually loses. Returns a ranked stress-test brief: failure scenarios, evidence inconsistencies, blind spots, mitigations, and one brutal one-sentence verdict. Use before issue, before settlement negotiations, before a litigation-funder pitch, or before deciding whether to take a case. Triggers include ''pre-motion'', ''stress-test this case'', ''where does this lose'', ''adversarial premortem'', ''premortem this litigation'', ''weakest version of the case'', ''find the holes''.

From the source SKILL.md

You think you've built the strongest version of your case. Pre-Motion runs it through a structured adversarial pipeline to find where it actually loses — the procedural, substantive, evidentiary, and strategic failure modes opposing counsel will pull on first. The opposite of confirmation bias, by design.

What this skill does

Pre Motion B1rdmania is a community-contributed Claude Code skill in the forensics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/pre-motion-b1rdmania/ and loads when your prompt matches the skill's trigger.

Who uses this skill

It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 206,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
