Choose the date range and provider you want to inspect, then select a metric or breakdown to explore it. ## Read the Activity Card **Spend**, **Sessions**, and **Cost per session** describe the selected activity period. Depending on the available account data, the card also shows **Limits** or **Context from cache**. Limits show the provider's current account windows. They use their own reset periods, independent of the activity date range. A missing or unconfigured budget does not mean you have exhausted a limit. Availability depends on what the provider account exposes. Context from cache describes reuse of previously read context. This is an interesting metric because reading context from the cache is cheaper than passing new input tokens. A high rate of cache hits may indicate good AI usage habits. ## See Where Spend Went Explore **Projects**, **Tasks**, and **Tools** to understand how estimated spend is distributed. Select an item to inspect the available details. Tool spend allocates each turn's estimated model spend evenly across its tool calls. This does not measure each tool's actual execution cost. **Unattributed** is spend Faros cannot place, and MCP service charges are excluded. ## Follow an Observation Faros Desktop's Lumi observations may point to a change in activity, a recommendation, or a saving. Activity links can open Sessions with the corresponding range and provider. It's worth noting that provider choices remain available for enabled analysis sources even when the selected period has no activity for that provider. Widen the range or check collection settings if a view is empty. ## Related Guides * [Explore Projects and Tasks](/work/explore-projects-and-tasks.md) * [Find and Review Sessions](/sessions/find-and-review-sessions.md) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.desktop.faros.ai/for-you/understand-your-ai-activity.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
