Coding / product dossier
Tests agents in sandboxed worlds with synthetic personas, documents, tools, APIs and databases.
Product brief
Find your agent’s worst bugs before your users do. One command in Claude Code, Codex or GitHub Copilot builds a digital twin of your agent’s world: synthetic personas and documents, plus mocked tools, APIs and databases, in sandboxes that never touch production.
Why we selected it
A concrete approach to testing agents before deployment: synthetic users and documents plus mocked tools, APIs and databases. Integration with existing coding agents and sandboxes isolated from production make it useful.
