Snapshot of the Meeting Bot page

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

No annotations are provided, so the description carries the full disclosure burden, and it does state read-only semantics: it does not join another browser and does not change the meeting. That is a real behavioral claim beyond the schema. It leaves minor gaps, such as what happens if no page is open or whether the image is a fresh capture.

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?

Three short clauses in one pass: what is returned, what it does not do, and the alternative. The payload description is front-loaded and no sentence is filler.

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?

For a one-parameter read tool with no output schema, the description covers the return type (image content plus a people list), the side-effect profile, and the sibling alternative. An agent has everything needed to call it correctly.

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?

Schema coverage is 100% and the single meeting_id parameter is documented in the schema with its origin (create_broadcast or join_broadcast). The description adds nothing about the parameter, so the baseline 3 applies.

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 name 'snapshot' alone is ambiguous, but the description immediately specifies the payload: the participant list plus a PNG of the already-open Meeting Bot page, returned as image content. It also distinguishes itself from get_meeting_state, so an agent can choose between them without opening either schema.

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?

'get_meeting_state is the same people list without the picture' gives a clear routing rule to the sibling tool. It does not state explicit exclusions (e.g. when the picture is not wanted or when the snapshot would be stale), so it falls short of full when/when-not guidance.

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