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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description adds one genuinely new behavioral fact — 'Attendees are notified' — which is a side effect not visible in annotations. It says nothing about required permissions, reversibility, or what happens if the location type is invalid, so the added value is modest.

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, purpose first, side effect second, with zero filler. Every clause carries information an agent can act on.

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 destructive mutation with no output schema, the definition covers intent, the kinds of values accepted, and the attendee-notification side effect. It is still incomplete on how to build the nested location payload and what happens to the previously configured location, which matters given destructiveHint=true.

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 only 50% and the location object accepts arbitrary additional properties (`additionalProperties: {}`), so the payload shape per type is undocumented. The description largely echoes the type list already present in the schema's `type` field and gives no guidance on what fields to supply for an address versus a link versus a phone. That leaves the hardest parameter underspecified.

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 ('Change where a booking happens') and enumerates the location kinds (address, link, phone, installed video app), which is far more than a restatement of the name. It is not explicitly differentiated from nearby siblings such as bulk_set_default_location or mass_apply_host_location, so it stops short of a 5.

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?

There is no when-to-use or when-not-to-use guidance, and no alternative is named; an agent must infer that this is the per-booking edit and that list_location_options would be the discovery step. The only signal is the word 'booking' inside the purpose sentence.

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