Update Gear Collection

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

Annotations already provide destructiveHint=true and openWorldHint=true, lowering the burden on the description. The description adds that name, gear items, and activity types can be changed, but it does not disclose that gearUUIDs and activityTypes replace existing lists rather than incrementally updating them; this is an important behavioral nuance not fully conveyed.

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?

The description is a single sentence that is front-loaded with the core action and resource. It mentions the most important changeable aspects without restating schema details, making it concise and easy to parse.

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?

Given the rich input schema (100% property coverage) and annotations communicating destructive behavior, the description is largely sufficient for tool selection and basic invocation. It omits firstUseDate and the full replacement semantics, but these are already present in the schema, so the description does not need to repeat them.

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 each property already has a meaningful description, including the replacement semantics of gearUUIDs and activityTypes. The tool description adds no additional parameter-level meaning and omits firstUseDate, so it does not exceed the baseline set by 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 uses a specific verb ('Update') and a specific resource ('existing gear collection'), and it enumerates the updatable aspects (name, gear items, activity types). This clearly distinguishes it from sibling tools like create_gear_collection, delete_gear_collection, and update_gear.

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 'existing gear collection' implies this is for modifying an already-created collection rather than creating or deleting one, but there is no explicit guidance on when to prefer this over create_gear_collection, delete_gear_collection, or update_gear. Usage context is implied rather than stated.

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