Marketing Creative Builder
Purpose
Translate an approved commercial strategy into reusable, measurable creative assets without changing the strategy or making unsupported claims.
Invocation Boundary
- Require a commercial launch contract or an equivalent approved brief containing audience, objective, channel, CTA, claims, and constraints.
- Do not choose a new market, audience, offer, price, or positioning silently.
- Do not publish, schedule, message, upload, buy media, or edit external accounts.
- Do not require that the product was built by the MVP Factory.
Workflow
1. Verify inputs
Confirm channel, placement, campaign/experiment ID, audience, awareness stage, primary message, allowed proof, prohibited claims, CTA, destination, language, tone, visual assets, and approval owner. Return missing strategic decisions to $commercial-launch-architect.
2. Create a message system
Define the core promise, problem framing, proof, objection response, CTA, and 3-5 reusable message angles. Label unproven angles as hypotheses. Avoid fake urgency, fake scarcity, invented testimonials, and claims that exceed product evidence.
3. Build channel-specific artifacts
Follow references/channel-specs.md. Produce only requested formats, such as:
- Instagram/TikTok short-video hook, shot list, voiceover, on-screen text, caption, cover, and CTA;
- carousel slide copy, visual direction, caption, and alt text;
- stories with frame sequence and interaction prompt;
- static/post copy and visual brief;
- paid-ad variants only when paid media is explicitly in scope;
- creator outreach or customer-contact drafts, never sent automatically;
- landing/store-listing copy tied to the same message and conversion event.
When final bitmap generation is requested, invoke the available imagegen skill/tool for the image work. This skill remains responsible for the brief, claims, channel fit, variants, and QA.
4. Design real variants
Follow references/experiment-variants.md. Change one decision-driving dimension per experiment where possible: hook, proof, problem frame, format, or CTA. Do not label cosmetic differences as distinct hypotheses.
5. Add measurement metadata
Record campaign, creative, variant, channel, placement, CTA, destination, UTM values, hypothesis, primary metric, and pass/fail rule. Keep link metadata out of visible copy when the channel handles it separately.
6. QA and package
Use references/creative-quality.md. Produce the manifest defined in assets/creative-pack-manifest.schema.json, with source files, previews, dimensions/duration, copy, alt text, claims, approvals, and publication readiness.
Required Output
- creative strategy summary tied to the launch contract;
- channel-ready copy and production instructions;
- visual/video briefs and generated assets when requested;
- genuine experiment variants;
- accessibility fields;
- UTM and measurement metadata;
- claim/proof register;
- manifest with status
draft, review_required, or approved_for_routing.
Hard Stops
Do not mark a pack ready when a claim lacks evidence, required brand/product assets are missing, a platform format is unknown, regulated wording lacks approval, or the CTA/destination is unresolved.
1---2name: marketing-creative-builder3description: Build a channel-ready marketing creative pack from an approved launch contract, brand inputs, product evidence, and available screenshots or assets. Use for captions, carousels, short-video scripts, stories, ad variants, outreach drafts, landing copy, briefs, alt text, UTM metadata, and a production manifest. It creates artifacts but never publishes or contacts users.4---56# Marketing Creative Builder78## Purpose910Translate an approved commercial strategy into reusable, measurable creative assets without changing the strategy or making unsupported claims.1112## Invocation Boundary1314- Require a commercial launch contract or an equivalent approved brief containing audience, objective, channel, CTA, claims, and constraints.15- Do not choose a new market, audience, offer, price, or positioning silently.16- Do not publish, schedule, message, upload, buy media, or edit external accounts.17- Do not require that the product was built by the MVP Factory.1819## Workflow2021### 1.
