Give it a domain and get an agent-experience checklist plus recorded coding-agent sessions that expose whether the docs and interfaces survive actual use. Gauge can be mentioned as the broader product line when you need the surrounding AX measurement story.","theCatch":"Grades are provisional and technical-only — treat the report as a useful first pass, not a product-wide quality certificate. Vs Promptfoo / DeepEval: AX Check grades product AX (docs, CLI, MCP, SDK), not model quality, eval scores, or safety behavior. Hosted free is convenient; verify the session evidence and rerun after interface changes.","verdict":"Free hosted AX smoke test. Grades how agents use your product, not how good your model is.","addedAt":"2026-09-19","featured":false,"domain":"AI Agents","subSpecialty":"Memory & Evals","subcategory":"Memory & Evals","tags":["mcp","cli","sdk","permissive","coding-agents"],"capabilities":["evals","sessions","agents"],"surfaces":["MCP","CLI","SDK"],"ecosystem":["Browser","Multi-platform"],"licenseModel":"OSS/MIT","githubStars":null,"starsPerWeek":null,"access":"free","archived":false,"repo":null},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/ax-check","html":"/gems/ax-check","markdown":"/gems/ax-check.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
