What idea-validation does

The agent evaluates a startup step by step. First, it isolates the customer problem and searches online forums for real complaints. It scans 5 to 10 competitors, inspecting their pricing tiers and 1-star reviews. Market size is estimated with an explicit calculation rather than arbitrary claims.

The dialogue ends with a clear call: GO, TEST MORE, or PASS. The agent identifies the single largest risk and recommends the most affordable experiment to run next. Outputs are stored inside the 03-validation/ folder. The skill can also consult frameworks like Lean Canvas or The Mom Test.

Without WebSearch and WebFetch, this evaluation falls flat. Real feedback from forum posts and current rival pricing are necessary to keep the review objective.

What it helps with

  • Identify direct and indirect competitors alongside their lowest customer ratings
  • Calculate total addressable market with concrete math instead of guesses
  • Gauge whether a minimum viable product can be built in two weeks
  • Receive an unbiased verdict highlighting the primary risk before spending money

Example prompts for the agent

  • Stress test my startup concept for a freelance subscription tracker before I start coding
  • Analyze competitors and market demand for a B2B reporting micro-SaaS
  • Help me validate whether people actually pay for a local darkroom rental service
