A first-step workflow for deciding how to handle requests to build digital products, such as web apps, SaaS products, dashboards, APIs, and landing pages. It asks a few questions and sends the work to the appropriate specialist workflow.

Use it at the beginning of product work to classify what is being built, whether the idea is defined, and whether the project starts from an existing codebase or from nothing.

It prevents implementation from starting before the product type, idea, and existing codebase are understood. That reduces the chance of building the wrong thing or choosing an unsuitable approach.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00203	$0.02831
Opus 5.5	$0.00081	$0.01132
Sonnet 5.5	$0.00041	$0.00566
Haiku 4.5	$0.00020	$0.00283

Security

Grade A, and why

saas-router scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SaaS Router

This skill is the brain of the saas-builder plugin. It runs before any product work and decides which specialist skill should handle the request.

The one rule that cannot be broken

Do NOT write code, design a UI, or pick a stack before routing through this skill. Jumping straight to implementation is the most common failure mode — it produces generic output that ignores what the user actually needs. Route first, build second.

Analogy: this is the triage nurse at a hospital. Nobody goes straight to surgery. The nurse asks two or three quick questions, then sends the patient to the right specialist.

Workflow

Step 1 — Ask 2-3 quick routing questions

Do not interrogate. Ask only what is needed to classify the request. Pick from:

"What are you building — a landing page, a dashboard, or a full app/SaaS?"
"Do you already know exactly what it should do, or are you still shaping the idea?"
"Is there an existing product/codebase, or are we starting from zero?"

If the user's first message already answers these (e.g. "build me a pricing landing page for my course"), skip straight to routing — do not re-ask what is already known.

Step 2 — Route to the right specialist

Match the request (English or Spanish) against this table and activate the matching skill. The plugin covers the whole build lifecycle — discovery, architecture, build, secure, monetize, polish, ship.

Plan & design

User says / wants	Route to
"SaaS", "platform", "app", "MVP", "product" / "idea para", idea not fully defined	`product-discovery` → `architecture-primer` → build skills → `ui-design`
"architecture", "how do I structure this", "scale", "what stack" / "cómo lo estructuro", "qué stack"	`architecture-primer`
"landing", "sales page", "lead capture" / "página de ventas", "captar leads"	`landing-page` (structure + copy) + `design-taste-frontend` (visual execution) — and the `landing-moment` plugin for the hero, if installed

"dashboard", "admin", "backoffice", "internal tool", "data table", product/app UI / "panel", "tablero", "interfaz de la app"	`ui-design` (dashboard mode)
