Live Session Status

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds useful behavior beyond annotations by stating that no auth is required and that it returns an honest 'no live session' message when nothing is running.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the tool's purpose and return fields, followed by two important operational caveats. No sentence is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema exists, so return values need not be exhaustively explained in the description. Annotations cover safety, and the description covers the key edge case of no live session. Minor gap: with many live siblings, it could more explicitly position itself as the top-level live status endpoint.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters, so the baseline is 4. The description does not need to explain parameter semantics, and the empty input schema is fully consistent with a zero-argument status call.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource and scope: live F1 session status, and explicitly lists the returned fields (session name, flag/track status, lap count). This distinguishes it from the many live sibling tools such as get_live_time_gaps and get_live_track_status_history.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by calling itself 'Live F1 session status' and clarifies that no auth is required, but it does not state when to choose this tool over alternatives like get_live_session_clock or get_live_track_status_history. The 'no live session' behavior helps set expectations, but explicit when/when-not guidance is absent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
