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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile needs no restating. The description adds the useful scope detail that these are transcripts of the Cal Video call specifically, but says nothing about empty results, pagination, or transcript availability conditions.

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?

A single front-loaded sentence that identifies the resource and its scope with no filler. It could be tightened slightly by also naming the sibling it replaces, but nothing 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?

For a one-parameter read tool with full annotations and full schema coverage, the description is adequate but thin: it doesn't say whether results can be empty or how transcripts are paginated/limited. No output schema exists, so a sentence on response shape would have helped.

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 description coverage is 100% and the bookingUid parameter is fully documented, including a concrete example and provenance (returned by list_bookings or create_booking). The description adds no parameter information beyond the schema, 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?

States a specific verb and resource (list ... meeting transcripts) scoped to a booking's Cal Video call, which distinguishes it from the nearby list_booking_recordings by naming the artifact type. It doesn't explicitly reference the sibling, but the resource noun is precise enough for selection.

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?

No guidance on when to call this versus list_booking_recordings or list_booking_conferencing_sessions, and no prerequisites (e.g., that the booking must have had a Cal Video session). Usage is only implied by the resource being listed.

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