patch_my_collection

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

Annotations already idempotentHint=true, readOnlyHint=false, destructiveHint=false. The description adds minimal context beyond 'update'; it does not disclose side effects, permission requirements, or that only provided parameters are changed.

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?

Description is a single concise sentence, front-loading the purpose. However, it lacks any usage context or sibling differentiation, which would improve it without much added length.

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 simple update operation with nested params, the description is minimal. No output schema is shown (though context says it exists), and no prerequisites or return value info is provided. Annotations add safety context but description could be more complete.

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 100% with good descriptions for each parameter and nested fields. The tool description does not add extra meaning beyond what the schema provides, so baseline 3 is appropriate.

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 action 'update specified collection entry for current user', indicating a verb and resource. It distinguishes from sibling 'post_my_collection' (create) implicitly, but does not explicitly mention 'existing' or contrast with create.

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?

No guidance is provided on when to use this tool versus siblings like 'post_my_collection' for creation or 'get_my_collection' for reading. No context on prerequisites or exclusions.

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