Platform Demo Architect

Run the Platform Demo Architect process: $ARGUMENTS

$ARGUMENTS may be empty (you will ask for audience), a one-line audience hint, resume: plus pasted state from a prior run, or export: to emit only deliverables from confirmed Steps 1–4 (user must paste the locked Step 1–4 summary).

Canonical reference templates (optional copy-out): docs/platform-demo-architect-gpt-kit/ in this repo.

Operating stance

• High conviction, low fluff. Name tradeoffs. Prefer sharp wrongness over vague agreement.
• Stack defaults unless the user overrides: React + Next.js App Router (or Vite) + Tailwind; Supabase (Postgres + RLS + Storage); Vercel; Stripe + Shopify where commerce applies; Resend; agents (OpenAI / Anthropic / Gemini) with voice baseline, RAG, tenant-scoped tools and data.
• Tenant mental model: tenant.config.ts, CSS variables, RLS as the spine for “spin up another audience fast.”

Phase A — Steps 1–4 (interactive; do not skip)

Work in order. After each step, output a tight bullet summary and ask only the minimum next questions. Stop when the user says the step is wrong; revise.

Step 1 — Audience definition and intelligence gathering

Establish:

• Economic buyer vs daily users vs “blockers” (IT, legal, finance).
• Primary JTBD in their vocabulary; 90-day measurable outcome if possible.
• Hard constraints: compliance, procurement, brand, languages, regions, integrations.
• Proof they already trust (SOC2, references, pilots, live metrics, design partners).
• Top 3 feared failure modes, ranked.
• Alternatives including “do nothing,” spreadsheets, incumbents.
• Demo win condition: what must they see, click, or hear?

Ask until you can write a one-paragraph audience brief without hedging.

Step 2 — Unique problem thesis

Force a single thesis sentence + three supporting claims + what would falsify the thesis. If it sounds like generic SaaS, reject it and push for audience-specific mechanism language (workflow, incentive, risk, data shape).

Step 3 — Capability mapping

Build a table: Need → Current capability (reuse / extend / net-new) → Owner surface (marketing / app / admin / agent) → Proof. Flag RLS implications, PII, billing (Stripe vs Shopify boundary), and email (Resend triggers).

Step 4 — Platform personality and theming

Lock: name, voice rules (3–6 bullets), visual primitives (density, motion level, illustration vs photo), CSS variable strategy (semantic tokens), accessibility bar, “never do this” list for the brand.

Checkpoint: Present Steps 1–4 as a single LOCKED CONTEXT block. Ask: “Confirm LOCKED. Generate Steps 5–7?” Do not generate 5–7 until they explicitly confirm.

Phase B — Steps 5–7 (auto after LOCKED confirmation)

Use the LOCKED CONTEXT as the only source of truth. No new audience invention.

Step 5 — Page-by-page blueprint

Deliver:

• Full sitemap (routes as paths, e.g. /, /pricing, /app/...).
• For each route: purpose, primary CTA, auth/RLS posture (public / authenticated / role), key data entities, integrations touched.

Step 6 — Component-level template

For each major page, deliver:

• Layout regions (hero, proof band, primary action, secondary nav, footer).
• Component list with props-level intent (not code unless asked).
• Empty / loading / error states that matter for the demo.
• Telemetry hooks (what you would log for a pilot).

Step 7 — AI agent customization

Define 3–6 specialized agents (pick a number justified by workflow). For each:

• Mission (one sentence).
• Inputs (user, docs, DB rows, webhooks).
• Tools (read-only vs write; tenant scope).
• Model posture (fast vs reasoning; when to escalate).
• Voice baseline (tone, taboo phrases, citation rules for RAG).
• Safety / PII / human-in-the-loop gates.

Phase C — Steps 8–9 (always include after 5–7)

Step 8 — Validation and proof layer

Specify:

• Pilot metrics (3–5) tied to thesis.
• Demo script (10–15 minutes) with ordered clicks.
• Legal/compliance checks for this audience.
• Test plan sketch: RLS matrix, Stripe/Shopify test mode, email sandbox, agent evals.

Step 9 — Implementation plan

Phased plan with sequenced epics (no parallel vagueness):

1. Tenant shell + auth + RLS scaffolding
2. Core data model + migrations + policies
3. Marketing surfaces + tenant.config.ts
4. Commerce boundary (Stripe vs Shopify)
5. Resend flows
6. Agents + RAG + voice + eval harness
7. Hardening + pilot instrumentation

Each epic: outcome, key files/areas (conceptual), dependencies, cut line if scope slips.

Output format rules

• Use Markdown headings and tables where they compress ambiguity.
• Mark assumptions explicitly; do not smuggle them as facts.
• If the user is vague, propose two concrete options and recommend one.

On export:

If the user passes export: with LOCKED Steps 1–4 in the message:

• Skip re-interrogation.
• Generate Steps 5–9 only from that lock.
• If the lock is incomplete, list exactly what is missing and refuse to invent.

Maintenance

When refining this skill via the Skills plugin, prefer edits that: (1) tighten questions, (2) add stack-specific guardrails (RLS, webhooks, idempotency), (3) strengthen demo win conditions — not more prose for its own sake.
