# pre-motion Adversarial premortem for England & Wales civil litigation. Builds the strongest version of a case, then attacks it from four angles — procedural, substantive, evidentiary, strategic — to find where it loses before opposing counsel does. For solicitors stress-testing before issue, in-house counsel before sign-off, mediators valuing settlement, and litigation funders pricing a matter. ## Install Part of the [claude-for-uk-legal](https://github.com/b1rdmania/claude-for-uk-legal) plugin suite: ```bash /plugin marketplace add https://github.com/b1rdmania/claude-for-uk-legal /plugin install uk-litigation-legal@claude-for-uk-legal ``` Or install the single skill directly: ```bash cp -r pre-motion ~/.claude/skills/pre-motion ``` ## Usage ``` /pre-motion /pre-motion --depth=fast /pre-motion --depth=thorough ``` Run it against a matter with the facts, evidence references, claim heads, and the strongest version of the case as you see it. It returns a ranked stress-test brief. ## What it does - Builds the optimistic baseline — the strongest version the evidence supports. - Inspects the evidence: document gaps, cross-document contradictions, timeline holes, each flagged with a severity. - Runs four adversarial passes (parallel sub-agents where supported, otherwise sequential), each told the case has been lost and asked to walk back why — one per failure category. - Synthesises a brief: ranked failure scenarios with severity, likelihood and mitigation; evidence inconsistencies; blind spots; settlement-posture implications; and one one-sentence verdict. - Marks every uncertain point inline — `[CITE NEEDED]`, `[SME VERIFY]`, `[EVIDENCE FLAG]` — so nothing reads as settled. ## What it doesn't do - Predict the outcome — it surfaces failure modes, not results. - Decide whether to take, settle, or withdraw — those are counsel's calls. - Replace a formal counsel opinion. It is a structured prompt for that conversation, not a substitute. - Cover non-UK procedure (US federal, Scotland, Northern Ireland). - Verify case law against a live source — check any authority it cites before relying on it. ## Requirements - Claude Code or Claude Cowork. No MCP connectors required. - A matter to run against (facts and evidence references).
