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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=false, so the safety profile is covered. The description adds useful context that the result set can be narrowed by timestamp/cursor, but it discloses nothing about pagination limits, default ordering, or return shape.

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 with no filler. The core purpose comes first and the optional narrowing behavior follows immediately; every clause earns its place.

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 simple read-only list tool with annotations already covering safety, the description is adequate but incomplete: it omits pagination behavior, default result count, and any indication of what a booking record contains. With zero schema description coverage, those omissions matter more.

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 0%, so the description must carry the burden. It clarifies the semantics of cursor and updated_since ('only changes after a timestamp or cursor'), but says nothing about limit, its default of 25, its 100 maximum, or cursor format, leaving a meaningful gap.

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 states a specific verb and resource ('List ... interpreter bookings') and scopes it to 'this account', so an agent can immediately tell it apart from create/cancel/get siblings. It does not explicitly name or contrast against any sibling, which keeps it just short of the top band.

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 phrase 'optionally returning only changes after a timestamp or cursor' implies the tool's incremental-sync use case, but there is no explicit when-to-use or when-not-to-use guidance relative to get_booking or get_responses. Usage is inferable rather than stated.

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