Test a startup idea against audience need, problem urgency, current alternatives, buying motivation, and the smallest useful experiment.

Startup Idea Validator breaks a startup concept into falsifiable claims about audience, problem, current behavior, differentiation, and willingness to change. It checks those claims against available market evidence, identifies the assumption most likely to kill the idea, and recommends a small validation before product investment.
Klinko Skills run through the authenticated Klinko MCP. Add your API key once, connect the MCP client, and use this Skill without learning a command language.

Describe the market question directly; the Skill applies a consistent research standard and output.
KLINKO_MCP_API_KEYThe Free plan includes a one-time balance of 200 credits. View pricing. Never place the API key in prompts, logs, or a public repository.
Use it before building a full solution or treating positive feedback as demand. The output is a risk map and experiment sequence, not a ceremonial “validated” badge.
Turn the concept into explicit audience, problem, behavior, value, and adoption assumptions.
Compare each assumption with public evidence and existing alternatives.
Prioritize the uncertainty with the largest ability to invalidate the opportunity.
Use the complete question, then ask for evidence boundaries and the next test. The Skill keeps the research path consistent while the market question changes.

Separate conclusions supported by public evidence from inferences, and show what information is still missing.

The skill may find real frustration but show that trust, tax liability, and switching cost matter more than time saved. The first test should therefore examine delegated trust, not feature interest.
