checklists verbatim to references/ to reduce the context cost of loading the
skill.

+# Expert Panel Scoring
+
+## How It Works
+
+1. **Assemble 3-5 expert personas** relevant to the copy type
+2. **Each persona scores the copy 1-10** on their area of expertise
+3. **Collect specific critiques** — not just scores, but what to fix
+4. **Revise based on feedback** — address the lowest-scoring areas first
+5. **Re-score after revisions** — iterate until all personas score 7+, with an average of 8+ across the panel
+
+## Recommended Expert Panels
+
+**Landing page copy:**
+- Conversion copywriter (clarity, CTA strength, benefit hierarchy)
+- UX writer (scannability, cognitive load, user flow)
+- Target customer persona (does this speak to me? do I trust it?)
+- Brand strategist (voice consistency, positioning accuracy)
+
+**Email sequence:**
+- Email marketing specialist (subject lines, open/click optimization)
+- Copywriter (hooks, storytelling, persuasion)
+- Spam filter analyst (deliverability red flags, trigger words)
+- Target customer persona (relevance, value, unsubscribe risk)
+
+**Sales page / long-form:**
+- Direct response copywriter (offer structure, objection handling, urgency)
+- Skeptical buyer persona (proof gaps, trust issues, red flags)
+- Editor (flow, readability, conciseness)
+- SEO specialist (keyword coverage, search intent alignment)
+
+## Scoring Rubric
+
+| Score | Meaning |
+|-------|---------|
+| 9-10 | Publish-ready. No meaningful improvements. |
+| 7-8 | Strong. Minor tweaks only. |
+| 5-6 | Functional but has clear gaps. Needs another pass. |
+| 3-4 | Significant issues. Major revision needed. |
+| 1-2 | Fundamentally broken. Rethink approach. |
+
+## When to Use
+
+- **Always** for launch copy, pricing pages, and high-traffic landing pages
+- **Recommended** for email sequences, sales pages, and ad copy
+- **Optional** for blog posts, social content, and internal docs
+- **Skip** for quick updates, minor edits, and low-stakes content
