+name: hook-evaluator
+description: |
+  Evaluates ad hooks for scroll-stopping power. Returns PASS or FAIL with psychological trigger analysis, reasoning, and improvement suggestions. Calibrated against real thumbstop performance data.
+  Use when the user wants to evaluate, grade, judge, or score hooks they've written or generated.
+  Triggers: "evaluate hooks", "grade my hooks", "are these hooks good", "hook evaluation",
+  "judge these hooks", "rate my hooks", "will these hooks work", "hook review", "score my hooks"
+---
+
+# Hook Evaluator
+
+This skill evaluates paid social ad hooks for scroll-stopping power based on text alone. It classifies each hook as **PASS** or **FAIL**, identifies the psychological trigger (or lack thereof), and gives specific improvement suggestions.
+
+## Companion Skills
+
+| Task | Use Instead |
+|------|-------------|
+| Writing hooks from scratch | **hook-writing** |
+| Developing hooks into ad concepts | **ad-concept-generator** |
+| Writing UGC scripts from concepts | **ugc-scriptwriter** |
+
+---
+
+## Quick Start
+
+Need a fast read on your hooks? Just provide:
+
+1. **The hooks** — one or more hook texts to evaluate
+
+That's it. The evaluator will score each one immediately.
+
+**Note:** This is a strict judge — expect roughly 40% of hooks to pass. That's by design. Use the improvement suggestions to rewrite failures and re-evaluate.
+
+---
+
+## How to Use This Skill
+
+**Recommended workflow:**
+
+1. Generate hooks (with **hook-writing** or however you prefer)
+2. Run them through this evaluator
+3. Take any FAILs, use the improvement suggestions to rewrite
+4. Re-evaluate until your hooks pass
+
+A hook that passes this evaluator has the psychological structure of top-performing paid social ads.
+
+---
+
+## Evaluation Criteria
+
+You evaluate hooks for **scroll-stopping power based on text alone**. Classify each as PASS or FAIL.
+
+### What Makes a PASS
+
+A PASS hook deploys at least one strong psychological trigger through a recognizable tactic. The trigger must be strong enough that a cold viewer — no visual, no brand context — involuntarily needs to keep watching.
+
+### Psychological Triggers (the mechanism inside the hook)
+
+| Trigger | What It Does |
+|---------|-------------|
+| **Pattern Interrupt** | Something unexpected or counterintuitive that breaks scrolling autopilot |
+| **Identity Call-Out** | Makes a specific viewer self-select ("If your underwear is always wet") |
+| **Pain Agitation** | Mirrors internal experience so precisely the viewer feels understood |
+| **Curiosity Gap** | Open loop they need to close (must have real stakes, not just "guess what") |
+| **Social Proof / Credibility** | Only through confession, regret, or authority subversion (not "10,000 reviews") |
+| **Contrarian / Myth-Busting** | Challenges a belief they hold ("Your teeth are naturally supposed to be yellow") |
+| **Loss Aversion** | Implies the viewer is losing something or making a costly mistake |
+| **Visceral / Taboo** | Bodily, physical, or socially uncomfortable language that can't be ignored |
+
+### Tactics That Commonly Deliver Strong Triggers
+
+Confession ("I was wrong about..."), Contrarian ("Doctors don't want you to know..."), Warning ("Don't buy X until..."), Storytelling mid-drop (start mid-scene), If-Then with specific condition, Shocking Statement, Challenge, Demographic Callout with pain specificity, Reverse Psychology
+
+---
+
+## Calibration: Real Hooks With Real Performance
+
+These are real hooks and their actual thumbstop rates. Use them to calibrate your judgment.
+
+### Strong hooks (>45% thumbstop) — what PASS looks like:
+
+- **77.6%** — "Fluffco won the Oprah Daily Sleep Award as their favorite pillow."
+- **54.1%** — "Someone cooked here."
+- **53.1%** — "I honestly wish I never found out about these covers. Because now, I'm a customer for life."
+- **51.8%** — "This one easy mistake will cost you thousands when buying a used car."
+- **47.7%** — "Why did no one tell me these foods were hurting me?"
+- **45.5%** — "After 50 years of showering, I thought I knew what clean felt like."
+
+### Weak hooks (<20% thumbstop) — what FAIL looks like:
+
+- **17.1%** — "Here are three of my favorite air purifying plants."
+- **14.2%** — "My current obsession is the signature All You Bra from Pepper."
+- **13.0%** — "Here's why I love Factor meals."
+- **10.9%** — "We've been feeding Coda the farmer's dog fresh food since she was a little puppy."
+- **4.3%** — "Introducing QuickBooks with Intuit Intelligence."
+
+---
+
+## Clear FAILs (Always Fail Regardless)
+
+- Product or brand name before tension
+- Rhetorical question with an obvious answer
+- Benefit-first without pain
+- Announces the content format ("Here are 3 tips...")
+- Requires visual context to work
+- Vlog opener with no hook mechanism
+- Generic testimonial without prior skepticism
+- In-group language aimed at cold traffic
+
+---
+
+## Decision Logic
+
+Ask: **Does this text create genuine cognitive friction for a stranger?** Can you name the specific trigger, and does it feel strong?
+
+- Strong trigger clearly present → **PASS**
+- Trigger present but mild or generic → **FAIL**
+- No trigger, just information delivery → **FAIL**
+
+About 40% of hooks should pass. If you're passing most hooks, you're being too generous.
+
+---
+
+## Output Format
+
+For each hook, return:
+
+```
+[PASS or FAIL] — "[Hook text]"
+  Trigger: [The psychological trigger identified, or the failure mode]
+  Tactic: [The tactic format if recognizable]
+  Reasoning: [One sentence on what's working or what's missing]
+  Suggestion: [If FAIL — one specific rewrite direction. If PASS — what to preserve.]
+```
+
+End with a summary line:
+
+```
+X hooks evaluated: Y passed, Z failed
+```
+
+---
+
+## Troubleshooting
+
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| Everything passes | Being too generous with "trigger present" | Re-read the FAIL calibration examples — those all *seem* reasonable but lack real trigger strength |
+| Everything fails | Being too strict on mechanism | Re-read the PASS calibration examples — "Someone cooked here" passes at 54% despite seeming simple |
+| Can't identify the trigger | Hook might be doing too many things | Look for the single strongest mechanism — a hook only needs one clear trigger |
+| Suggestions feel generic | Not grounding in the specific hook | Rewrite suggestions should name the specific pain, identity, or tension to add |
