Groundtruth is a stop hook for Claude Code that prevents the AI agent from ending a turn on an unverified completion claim, forcing it to provide evidence or retract. Its novel approach to enforcing verification at the tool level, tuning against real session data, and supporting retroactive auditing make it a unique contribution to the AI-agent tooling ecosystem.

Target audience: backend devs, devops, AI engineers
