chromie.dev employs deterministic tool calls for web agents: analyze past executions, build tailored tools around repeated actions, and invoke skills at runtime based on task and position. We use the model for the "why," but we enforce the "how" through deterministic skills. Don't risk the web agent reasoning through the DOM and making a costly mistake. Our skillset of self-healing tooling continually expands with automation flows seen, keeping us up to date and always growing.
