A themed Instagram grid the founder can ship

Nine-slot launch board for an indie ceramic wellness brand — palette-locked, style-rotated, ready to drop into the founder's content calendar.

An indie founder is launching a handmade ceramic morning-ritual brand. She has 30 minutes between two production batches and a kid's pickup. She needs nine themed Instagram grid posts — hero shot, lifestyle, flat lay, surface texture, atmospheric, typography overlay, repeat — that all carry the same warm-honey-and-ceramic vibe. She has no design team, no Photoshop, and no patience for prompt engineering.

The agent flow

Same three-call shape as the Pure North product-marketing case study, scoped to the social-launch use case.

1. brand_kit_create — palette (cream / honey gold / ceramic brown), prompt keywords ("calm morning ritual", "ceramic vessel", "slow living"). Returns ckit_afe6b68551.
2. moodboard_create — title + intent + kit. Returns mood_c42e042952.
3. moodboard_spread — 9 slots, max_cost_usd: $3.50, six style hints rotated (hero shot · lifestyle · flat lay · surface · atmospheric · typography overlay).

The grid

From grid to Instagram Reel

A grid lands in the feed; a reel lands in the algorithm. One more create_media action=animate call on the strongest slot turns the static hero into a 5-second vertical-friendly motion clip — steam rising, gentle subject rotation, calm slow-living aesthetic. The founder can drop this directly into Instagram's reel uploader. Cost: ~$0.30.

What makes this an indie-friendly shape

• One palette lock, nine themed shots. The brand kit's hex palette and prompt keywords were prepended to every slot's prompt automatically. The founder didn't write nine prompts — she briefed an intent and the system varied the style cards.
• Four-cap diversity, not flux-dev nine-times. Slot 1 nano-banana, 2 recraft-v4, 3 flux-dev, 4 gemini-image, then repeats. The grid reads as varied rather than mechanical.
• Cost preview before commit. max_cost_usd: $3.50 meant the call refused if the estimated spread exceeded the cap. Actual spend $0.38, well under.
• Share without an account. The viewer URL works for the founder's three collaborators (her partner, her potter, the ceramicist who supplies the bisque). None of them have to make accounts. None of them have to download a 12 MB ZIP.
• 14-day public-share TTL. Long enough for a launch cycle, short enough not to leak indefinitely. Configurable up to 90 days via moodboard_publish.

How this compares for indie founder workflows

Capability	Storyboard MCP	Canva Magic Studio	Adobe Express	Photoroom
Theme-locked multi-slot grid in one call	✓ moodboard_spread count:9	One asset at a time	One asset at a time	One asset at a time
Multi-model stylistic diversity	✓ 4-cap round-robin	Adobe Firefly only	Firefly only	Single Photoroom model
Agent-callable (MCP)	✓ Native	No API for AI image gen	Adobe Firefly REST API only	REST API, no MCP
Cost transparency before submit	✓ max_cost_usd pre-flight	Per-month subscription	Per-month subscription	Per-image credit
Public shareable viewer URL	✓ 14-day TTL, auto-published	Canva project link (req. account to view)	Adobe link (req. account)	Photoroom share
Pricing for 9-slot launch grid	~$0.38	~$12/mo flat (with Pro)	~$10/mo flat	~$1.80 (~$0.20/img)
Indie-friendly forbidden-terms list	✓ Per-kit array	No	No	No

The competitive numbers are from each vendor's published pricing as of mid-2026. The fundamental shape difference: Canva / Express / Photoroom are creator-first SaaS UIs with bolt-on AI; Storyboard is an MCP-first surface designed to be driven by an agent. For an indie founder with an agent (Cursor, Cowork, Codex) already in their flow, the agent-callable surface eliminates the context switch.

The agent surface as it actually shipped

This case study exercises the post Z+AX agent surface. The pieces that pay rent here:

• AX-3 (tool description audit) — moodboard_spread vs place_subject vs create_variations have explicit "USE WHEN" delimiters so the agent picks the right tool the first time.
• AX-5 (latency SLA) — list_capabilities now reports p50/p95 per capability, so when the founder's agent picks a slow premium model like gpt-image, it knows beforehand that the call will run 35-90 s.
• AX-2 (cost parity) — Cost surfaces on every job-status response. The agent never has to call get_pricing mid-flow to check.
• AX-6 (URL normalization) — Every slot URL is canonical https + lowercase host. The founder copy-pastes into a content calendar and it just works.
