The "Agent Usage" line item covers LLM token consumption from Railway's built-in AI Agent, which includes canvas chat, deployment diagnosis, and code-change suggestions within the Railway dashboard. Your current billing period shows $2.09 in Agent usage so far, with a $10 hard limit. This is separate from any external tool like Claude Code. If you'd like to reduce or eliminate Agent charges, you can set the Agent hard limit to $0 at your workspace usage page by clicking "Update limits", which disables Agent features without affecting the rest of your services. For details on how Agent usage is priced, see our pricing reference.
