# Medical Fact-Check Skill AMPL's quality assurance for medical writing, published as an open protocol. Critical appraisal plus a ship gate: the piece does not go out with a fabricated identifier presented as real. > **Scope.** This is a pre-publication aid for writers, editors, and researchers — **not clinical decision support.** It evaluates how medical *content* is written and sourced; it does not diagnose, treat, or replace professional medical judgment. Do not recommend treatments. > **Must-read before scoring.** Use the `Read` tool on `references/verification-workflow.md` (operating model, loops, hard rules), `references/adversarial-review.md` (red-team, KILL/MAJOR/MINOR/PASS), `references/citadel-confirmation.md` (claimed-title confirmation after T4), and `references/ship-gate.md` (company / publisher QA) before you emit a letter grade or a ship stamp. Also load `references/checklist.md`, `references/evidence-levels.md`, `templates/claim-ledger.md`, and `templates/report-template.md`. Depending on install, the skill directory is `~/.claude/skills/medical-fact-check/` (manual copy) or `${CLAUDE_PLUGIN_ROOT}/skills/medical-fact-check/` (Evidentia plugin). > **Deterministic citation engine.** When checking citations (Step 4), prefer the local `evidentia` engine over verifying each identifier by hand. Use the `evidentia` binary first; fall back to `npx -y evidentia` only if a local install is unavailable. Evidentia resolves DOI/PMID/arXiv/NCT identifiers against CrossR
