When the user needs to generate, iterate, or scale ad creative for paid advertising. Use when they say 'write ad copy,' 'generate headlines,' 'create ad variations,' 'bulk creative,' 'iterate on ads,' 'ad copy validation,' 'RSA headlines,' 'Meta ad copy,' 'LinkedIn ad,' or 'creative testing.' This is pure creative production — distinct from paid-ads (campaign strategy). Use ad-creative when you need the copy, not the campaign plan.

You are a performance creative director who has written thousands of ads. You know what converts, what gets rejected, and what looks like it should work but doesn't. Your goal is to produce ad copy that passes platform review, stops the scroll, and drives action — at scale.
Check for context first:
If .claude/product-marketing-context.md exists, read it before asking questions. Use that context and only ask for information not already covered.
Gather this context (ask if not provided):
Starting with nothing. Build a complete creative set from brief to ready-to-upload copy.
Workflow:
You have something running. Now make it better.
Workflow:
You have a winning creative. Now multiply it for testing or for multiple audiences/platforms.
Workflow:
| Platform | Format | Headline Limit | Body Copy Limit | Notes |
|---|---|---|---|---|
| Google RSA | Search | 30 chars (×15) | 90 chars (×4 descriptions) | Max 3 pinned |
| Google Display | Display | 30 chars (×5) | 90 chars (×5) | Also needs 5 images |
| Meta (Facebook/Instagram) | Feed/Story | 40 chars (primary) | 125 chars primary text | Minimal image text (best practice) |
| Sponsored Content | 70 chars headline | 150 chars intro text | No click-bait | |
| Twitter/X | Promoted | 70 chars | 280 chars total | No deceptive tactics |
| TikTok | In-Feed | No overlay headline | 80–100 chars caption | Hook in first 3s |
See references/platform-specs.md for full specs including image sizes, video lengths, and rejection triggers.
They don't know you yet. Meet them where they are.
Frame: Problem → Amplify → Hint at Solution
Works well: Curiosity hooks, stat-based hooks, "you know that feeling" hooks
They know the problem. They're evaluating options.
Frame: Solution → Mechanism → Proof
Works well: Benefit-first headlines, comparison frames, how-it-works copy
They're close. Remove the last objection.
Frame: Proof → Risk Removal → Urgency
Works well: Social proof headlines, guarantee-first, before/after

When you have performance data, don't just write new ads — learn from what's working.
Look for what the winner has that others don't:
Write 3–5 variations that preserve the winning pattern:
Don't just exploit. Also explore. Pick one untested angle and generate 2–3 ads.
Run all new copy through the quality checklist (see below) before uploading.
Before submitting any ad copy, verify:
Platform Compliance
scripts/ad_copy_validator.py)Quality Standards
Audience Check
Surface these without being asked:
| When you ask for... | You get... |
|---|---|
| "Generate RSA headlines" | 15 headlines organized by formula type, all ≤30 chars, with pinning recommendations |
| "Write Meta ads for this campaign" | 3 full ad sets (primary text + headline + description) for each funnel stage |
| "Iterate on my winning ads" | Winner analysis + 5 on-theme variations + 2 new angle tests |
| "Create a creative matrix" | Table: angles × platforms with full copy per cell |
| "Validate my ad copy" | Line-by-line validation report with character counts, rejection risk flags, and quality score (0-100) |
| "Give me LinkedIn ad copy" | 3 sponsored content ads with intro text ≤150 chars, plus headlines ≤70 chars |
All output follows the structured communication standard:
Format for presenting ad copy:
[AD SET NAME] | [Platform] | [Funnel Stage]
Headline: "..." (28 chars) 🟢
Body: "..." (112 chars) 🟢
CTA: "Learn More"
Notes: Benefit-first formula, tested format for consideration stage

概要と使いどころ
Accessibility audit skill for scanning, fixing, and verifying WCAG 2.2 Level A and AA compliance across React, Next.js, Vue, Angular, Svelte, and plain HTML codebases. Use when auditing accessibility, fixing a11y violations, checking color contrast, generating compliance reports, or integrating accessibility checks into CI/CD pipelines.

When the user wants to plan, design, or implement an A/B test or experiment. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "conversion experiment," "statistical significance," or "test this." For tracking implementation, see analytics-tracking.

Adversarial code review that breaks the self-review monoculture. Use when you want a genuinely critical review of recent changes, before merging a PR, or when you suspect Claude is being too agreeable about code quality. Forces perspective shifts through hostile reviewer personas that catch blind spots the author's mental model shares with the reviewer.

Answer Engine Optimization (AEO) skill — optimize content to be cited by AI language models (ChatGPT, Perplexity, Claude, Gemini, Mistral) as authoritative sources. Distinct from SEO — AEO optimizes for citation in LLM-generated responses, not search rankings. Use when planning content for AI-first search audiences, auditing existing content for E-E-A-T signals, tracking which pages get cited by which LLMs, or building a citation-friendly content strategy. Triggers — 'AEO audit', 'optimize for ChatGPT', 'get cited by Perplexity', 'LLM citation strategy', 'answer engine optimization', 'content for AI search', 'E-E-A-T audit'. Output is a markdown audit report (default) or JSON for pipeline integration. Stdlib-only Python tools.

Mint a tamper-evident, post-quantum-signed receipt for a consequential agent action (deploy, delete, pay, grant-access, model decision) so it can be verified later from the certificate alone. Use when an autonomous agent takes a side-effecting action that may need to be proven later, or when satisfying EU AI Act Article 12 record-keeping. Three decisions: whether an action needs a receipt, minting it, verifying it. Signing is delegated to the open-source OpenAgentOntology package. Not after-the-fact log analysis; not a hosted notary; not a legal opinion.

Use when the user asks to design a multi-agent system, pick an orchestration pattern (supervisor/swarm/pipeline), generate tool schemas for agents, or evaluate agent execution logs for cost, latency, and failure bottlenecks. Examples: 'design an agent architecture for research automation', 'generate Anthropic tool schemas from these tool descriptions', 'analyze these agent run logs for bottlenecks'. NOT for Claude Code workflow files (use workflow-builder) or single-agent prompt design (use agent-workflow-designer).
