update_gear_reminder

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action and return value; it does not explain whether optional nulls mean 'no change' or 'clear value', nor does it mention error handling or side effects. This is a significant gap for a mutation tool.

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 concise and logically organized with an opening sentence, parameter list, and return statement. It avoids unnecessary fluff, though the parameter list is somewhat redundant with the schema. Overall, it's efficient.

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 present and full parameter descriptions, the description is mostly complete for a simple update. However, it lacks critical behavioral context such as semantics of optional parameters (null vs omitted) and failure behavior, which reduces completeness.

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 the schema already documents all parameters and their meaning. The description's Args list simply mirrors the schema without adding extra semantic detail, such as units or interplay between distance_alert and time_alert.

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 clearly states the tool's purpose with a specific verb ('Update') and resource ('existing gear maintenance reminder'), which distinguishes it from sibling tools like create_gear_reminder and update_gear. The scope is unambiguous.

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 description implies usage for modifying existing reminders but does not explicitly state when to use it over create_gear_reminder or update_gear. It lacks explicit exclusions or alternative references, though the word 'existing' hints at the use case.

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