Reddit Product Validation Agent
Reddit Product Validation Agent
Validate startup ideas with a two-phase workflow: discover relevant subreddits, then analyze pain points, existing solutions, willingness to pay, demand trends, and early adopters. Get a go/no-go scorecard with actionable insights.
Use this when you have a startup idea and want an agent to find relevant subreddits, then mine them for demand signals and a go/no-go scorecard.

Similar patterns, and when each one is the better fit.
Evaluator-Optimizer PatternUse this when you want one orchestrator agent to loop evaluator and optimizer tools over a draft until it meets a quality bar or hits a step limit.
Competitor Research AgentUse this when you have one competitor URL and need a brief you can trust: pricing, features, and tech read from the site, plus agent analysis that quotes its evidence.
Branding AgentUse this when you want a grounded agent that pulls a site's brand tokens and answers contrast, palette, and voice questions from the scraped page.
Jev EvalsUse this when you need per-PR eval checks for an agent that diff a candidate run against a stored baseline to flag fractional drops.
