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

Annotations already declare destructiveHint=true and idempotentHint=false, so the destructive nature is partly covered. The description adds meaningful context beyond annotations: that an approval is required by default, which is a workflow constraint an agent must know before invoking.

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 with zero waste; the trigger condition is front-loaded ahead of the safety/approval note. Every sentence 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?

With an output schema handling return values and annotations covering the safety profile, the description need only convey the trigger and the approval requirement, which it does. Minor gap: it doesn't clarify approval_id acquisition, though that is left to sibling approval tools.

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%, so both place_id and approval_id are fully documented in the schema, setting the baseline at 3. The description's mention of approval loosely relates to approval_id but adds no format or constraint detail beyond the schema.

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 action (removing a saved place) and frames it around user intent, which is clear. It doesn't explicitly name itself against the sibling places.update/places.create, but the delete semantics are unambiguous given the name and title.

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 gives a usage trigger ("When the user wants a saved place removed") but offers no when-not guidance and doesn't reference alternatives like places.update or places.list. Usage is implied rather than fully specified.

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