| description | Evaluate the quality of any AI-generated artifact — visualizations, code, documents, conversations, or any skill output. Works in 3 phases: (1) Generate evaluation specs tailored to the artifact type, (2) Run comprehensive evaluation against those specs, (3) Produce a beautiful visual report using the /visualize skill. Use after any skill produces output, or invoke directly with /evaluate <file-or-context>. Supports evaluating: HTML visualizations, code projects, documents, agent conversations, slide decks, dashboards, or any artifact with quality dimensions.

Evaluate
Comprehensive quality evaluation for any AI-generated artifact. Produces its report as a visualization.

Phase 1: Spec Generation
For any artifact, generate evaluation specs by analyzing:
1. Identify Artifact Type
- HTML Visualization → visual design, interactivity, technical, content, shareability
- Code/Project → correctness, readability, architecture, test coverage, performance
- Document/Report → clarity, structure, accuracy, completeness, tone
- Conversation/Agent → helpfulness, accuracy, tone, efficiency, safety
- Slide Deck → all visualization dims + narrative flow, persuasion, pacing
- Dashboard → data accuracy, information density, scannability, actionability
- Custom → derive dimensions from the skill's SKILL.md and stated goals
2. Generate Dimensions
For each artifact type, produce 6-10 evaluation dimensions. Each dimension needs:
- Name — short, clear label
- Description — what this dimension measures
- Weight — percentage (all weights sum to 100%)
- Scoring anchors — what does a 10, 8, 6, 4 look like?
- Automated checks — any programmatic tests (if applicable)
- Deductions — specific issues and their point costs
3. Set Quality Gates
Define gates based on the artifact's purpose:
| Gate | Criteria | Meaning |
|---|
| 🚀 EXCEPTIONAL | Overall ≥ 9.5, all ≥ 9 | Best-in-class. Share everywhere. |
| ✅ SHIP | Overall ≥ 9.0, all ≥ 8 | Production-ready. |
| ⚠️ ACCEPTABLE | Overall ≥ 8.0, all ≥ 7 | Usable but not impressive. |
| 🔧 NEEDS WORK | Overall ≥ 7.0 or any < 7 | Fix before releasing. |
| ❌ FAIL | Overall < 7.0 or any < 5 | Major rework. |
4. Output Spec Document
Write the spec to eval-spec-[artifact-name].md for reference and reuse.
Phase 2: Evaluation
For HTML Visualizations
Open in browser at 3 viewports (1280×720, 768×1024, 375×667).
Automated audit (run in browser console):
(function() {
const audit = {};
const style = [...document.querySelectorAll('style')].map(s => s.textContent).join(' ');
const html = document.documentElement.outerHTML;
audit.hasDoctype = /^<!doctype html>/i.test(html);
audit.hasLangAttr = !!document.documentElement.lang;
audit.hasCharset = !!document.querySelector('meta[charset]');
audit.hasViewport = !!document.querySelector('meta[name="viewport"]');
audit.hasTitle = document.title.length > 0;
audit.menuExists = !!document.querySelector('.viz-menu');
audit.menuHasTheme = !!html.match(/cycleTheme|themeLabel/i);
audit.menuHasDownload = !!html.match(/htmlToImage|html-to-image/i);
audit. = !!html.();
audit. = !!style.();
audit. = !!style.();
audit. = !!style.();
audit. = !!html.();
audit. = !!html.();
audit. = !!style.();
audit. = ((.).);
audit. = audit. >= ;
audit. = !!(style.());
audit. = !!style.();
audit. = !!style.();
audit. = !!style.();
audit. = !!style.();
audit. = !!style.();
audit. = !!html.();
audit. = !!html.();
audit. = !!style.();
audit. = !!style.();
audit. = .( ([html]). / );
audit. = audit. < ;
audit. = .(). === ;
audit. = htmlToImage !== ;
bools = .(audit).( v === );
passed = bools.( v).;
audit. = passed;
audit. = bools.;
audit. = .(passed / bools. * );
audit. = bools.( !v).( k);
.(audit);
audit;
})();
Visual scoring — 8 dimensions for visualizations:
| # | Dimension | Weight | 10 = | 6 = |
|---|
| D1 | First Impression | 15% | Apple keynote quality | Generic template feel |
| D2 | Typography | 15% | Perfect hierarchy, Inter font, fluid sizing | All same size, no hierarchy |
| D3 | Color & Contrast | 10% | Harmonious, WCAG AA, both themes beautiful | Clashing, low contrast |
| D4 | Layout & Spacing | 15% | Consistent rhythm, responsive, generous space | Cramped, broken at mobile |
| D5 | Content Quality | 15% | Clear message in 5 seconds, zero filler | Confusing, placeholder text |
| D6 | Interactivity | 10% | Menu + theme + download + print all flawless | Missing features, broken |
| D7 | Technical | 10% | Zero errors, semantic, accessible, print-ready | Console errors, broken layout |
| D8 | Shareability | 10% | Would tweet this unprompted | Worse than Canva |
For Code/Projects
Dimensions: Correctness, Readability, Architecture, Error Handling, Performance, Testing, Documentation, Security
For Documents
Dimensions: Clarity, Structure, Accuracy, Completeness, Tone, Formatting, Actionability, Brevity
For Agent Conversations
Dimensions: Helpfulness, Accuracy, Tone, Efficiency, Safety, Context Awareness, Tool Usage, Follow-through
Phase 3: Visual Report (via /visualize)
After scoring, generate the eval report as a beautiful HTML dashboard using the visualize skill:
Report Structure
- Hero — artifact name, overall score (big number), quality gate badge
- Radar Chart — all dimensions plotted on a radar/spider chart (Chart.js)
- Dimension Cards — each dimension as a card with score, bar, key notes
- Automated Audit — pass/fail checklist with percentages
- Screenshots — key views embedded (if HTML artifact)
- Fix List — prioritized fixes as a kanban-style layout (critical / high / medium / low)
- Systemic Issues — patterns that affect all outputs (flagged for SKILL.md fixes)
- History — if re-evaluating, show before/after score comparison chart
Report Filename
eval-report-[artifact-name]-[date].html
The report itself must score ≥ 9.0 on the visualize eval criteria.
This is the ultimate dogfood test — our evaluation tool produces evaluations using our visualization tool.
The Improvement Loop
Generate artifact (any skill)
↓
/evaluate → Spec + Score + Visual Report
↓
Review report → identify fixes
↓
Fix (systemic → SKILL.md, local → artifact)
↓
/evaluate again → compare scores
↓
Ship when gate = SHIP or EXCEPTIONAL
Max 3 loops per artifact. If it can't reach SHIP in 3 loops, the problem is in the skill — update the skill's instructions, not the artifact.
Quick Start
# Evaluate a visualization
/evaluate path/to/visualization.html
# Evaluate with custom context
/evaluate path/to/code-project --type code
# Re-evaluate after fixes (tracks improvement)
/evaluate path/to/visualization.html --loop 2
# Generate specs only (no scoring)
