Stack Selector
Recommends the right technology stack for your product, branching by product type (consumer mobile, B2B SaaS, internal tool, API/developer tool, marketplace, AI-native).

Produces a stack-decision.md with specific tool recommendations and setup order.
Customer Hypothesis
Builds a sharp, specific customer profile you can actually build for — not a demographic, but a person in a situation.

Produces an integrations-plan.md with specific tool choices and the order to add them.
Problem Validator

Use when you have a product idea and want to validate it's solving a genuine problem, or when you're unsure if people actu…
Architecture Explainer
Explains your product's technical architecture in plain English — so you understand what's being built, can make informed decisions, and can describe it to others.

Assumption Mapper
Maps every key assumption in your product plan to a validation method and priority level. Spawns parallel research agents — one per assumption — to gather evidence simultaneously.
