SubscripitonItems_Updateasubscr

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

The description only confirms the tool performs an update, but no annotations exist to disclose effects like idempotency, destructiveness, or permissions. The minimal statement leaves key behavioral details unspecified.

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, short sentence with no redundant words. It is appropriately concise for a simple action.

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 that the tool has one complex parameter (body object) and no output schema, the description is too sparse. It does not explain what fields the body should contain, what response to expect, or any side effects. This lack of completeness hinders correct invocation.

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% as the single 'body' parameter has a description 'Request body', but that adds no semantic depth beyond naming. The description does not elaborate on expected fields within the body, so it provides only marginal value over 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 clearly states the verb 'Update' and the resource 'a subscription item', making the action unambiguous. However, it does not differentiate from sibling tools like 'Subscriptions_Updateasubscripti' which updates a whole subscription, but the distinction is implied by the resource name.

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 alternatives such as 'SubscripitonItems_Retrieveasubs' or 'SubscripitonItems_Listallsubscr'. The description does not mention prerequisites or conditions.

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