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

Beyond the readOnlyHint/openWorldHint annotations, the description adds real behavioral context: results are ordered newest first, each item carries a link, and link access is gated by the recording's own sharing setting. That sharing detail is exactly the kind of access caveat annotations cannot express; only pagination/limit behavior is left unstated.

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 tight sentences: the primary behavior and ordering come first, the optional filter second, and the sharing caveat last. Nothing is redundant with the title or the schema.

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 single-parameter read tool with no output schema, the definition covers purpose, ordering, returned fields (links), and access semantics. It is nearly complete; the only meaningful gap is the identifier format for the optional meeting filter.

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 0% for the single `meeting` parameter, so the description must compensate. Saying it is optional and scopes to 'one meeting' genuinely helps, but it never says whether the value is an ID, title, or date, so an agent can still guess wrong.

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 definition names a specific verb and resource ('Lists ... recordings and clips') and adds scope ('the signed-in person's'), so the agent can immediately tell this apart from list_meetings, get_transcript, or get_notes without opening the 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?

It conveys the one real usage variation, 'optionally for one meeting', but does not say when to prefer this over related retrieval tools (for example, getting a transcript) or what happens with no argument. The usage is implied rather than explicit.

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