3 agents (concept → spec-and-legibility → critic) turn a message into an OOH-ready brief + render manifest: one idea, legible in 3 seconds at distance/speed, specced to the placement's real dimensions and production constraints. Like produce-asset, this emits a brief + render-ready prompt + manifest — it holds no API keys and renders no pixels (an operator-connected engine does that via references/_shared/execution-fork.md). Method: references/agent-manifest.md.
Core question: Read at 60 mph from 200 feet in under 3 seconds — does one message land?
Critical Gates — load first
- One message. OOH is a single idea — a brand, an offer, or a line. Two messages = zero messages.
- The 3-second read. Legible at the placement's real viewing distance + speed. ≤7 words is the working ceiling for a highway board.
- Contrast + scale over detail. Big type, high contrast, minimal copy; no small print, no QR-as-the-CTA on a moving placement.
- Brand-anchored. FORSVN: Forest Shadow / Leaf accent, matte, no gradients/glass; the brand reads even at a glance.
Before Starting
Apply references/_shared/before-starting-check.md. Resolve via ≤4 Cold Start questions only what's unstated:
| Dimension | Why |
|---|---|
| OOH type (billboard / transit / poster / wrap) | drives dimensions + the read budget |
| The one message + the goal | the single idea everything serves |
| Placement context (highway / station / street / building) | viewing distance + dwell time |
Brand assets (brand/BRAND.md, logo, fonts) |
on-brand legibility |
Mode per references/_shared/mode-resolver.md. budget: standard. --fast → concept + core spec, skip the production-note depth; never skips the legibility check (the safety floor). Per the mode-resolver, --fast does drop the critic gate.
Quality Gate — 5 dimensions
Full rubric: references/agent-manifest.md § Rubric.
- 3-second read — one message, legible at the stated distance/speed (≤7 words for fast placements)
- Single idea — no competing messages
- Legibility — type size, contrast, safe margins meet the placement spec
- Format fidelity — correct dimensions, bleed, resolution, file spec for the medium
- Brand fidelity — on-brand, matte, accent discipline
Pass ≥35/50 AND no dim 0. FAIL twice → BLOCKED.
Artifact Contract
- Path:
docs/forsvn/artifacts/marketing/produce-ooh/[ooh-type]-[YYYY-MM-DD]-[slug].md. Lifecycle:execution. - Frontmatter (11):
skill,version,date,stack,type,id,review_surface,status,ooh_type,execution_mode,keywords. - Body: Concept (the one idea + visual) · The OOH spec (dimensions · bleed · resolution · type sizes · contrast · safe margins) · Copy (≤word-ceiling) · Render manifest (prompt + asset slots) · Production notes (substrate, lighting, lead time) · Critic verdict.
- Render: emits a render-ready prompt + manifest; pixels come from an operator-connected engine (
references/_shared/execution-fork.md). Full contract:references/format-conventions.md.
Routing + Dispatch
Sequential graph (concept → spec-and-legibility → critic): references/agent-manifest.md.
Chain Position
Prev: plan-campaign (the campaign + media context) OR create-brand. Next: the operator-connected render engine; measure-results if the OOH carries a trackable code/URL. Re-run: new placement, dimension change, message pivot.
Deference: digital/social ad creative → write-ad / brief-graphic / produce-asset; the media buy/plan → plan-campaign; a motion/video placement → brief-shortform / produce-video.
Anti-Patterns
references/anti-patterns.md — 7 patterns (two-messages, too-many-words, low-contrast, small-print, QR-on-fast-placement, wrong-dimensions, off-brand). Re-read before ship.
Durable Rules (protected)
Completion Status
- DONE — concept + spec + manifest, passes the 3-second read, critic ≥35.
- DONE_WITH_CONCERNS — delivered; critic 25-34 OR an unresolved placement/dimension unknown (flagged).
- BLOCKED — critic FAIL twice; OOH type or dimensions undefined.
- NEEDS_CONTEXT — no message or placement; recommend defining the one idea + the placement first.
