subscription_introductory_offers_update_instance

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

No annotations are provided, so the description carries the full behavioral burden. It discloses only the HTTP method and that the body follows a JSON:API envelope defined in the OpenAPI schema; it says nothing about partial-update semantics, required permissions, side effects, or reversibility of changing an introductory offer.

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 short and front-loaded with the endpoint, but the path is redundantly duplicated in parentheses and the second sentence is a bare pointer to an external schema, so some of the limited text is wasted.

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?

For a mutation endpoint with a nested JSON:API body, no annotations, no output schema, and no domain explanation, the description delegates everything to the OpenAPI spec. An agent gains no understanding of what can be updated or what the update affects, which is inadequate for this complexity.

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 baseline is 3. The description adds no meaning beyond the schema: the id parameter is already documented as 'the id of the requested resource' and the body only points back to the same OpenAPI component the schema references.

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?

It states a method and resource (PATCH on subscriptionIntroductoryOffers), so an agent can tell it is an update of that resource. However, it is essentially a mechanical restatement of the name as an HTTP path, with no domain-level explanation of what updating an introductory offer means, and no differentiation from the create/delete siblings.

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 PATCH verb implies an update operation, but the description gives no explicit when-to-use, when-not-to-use, or alternatives (e.g. create vs delete vs the parent subscription's offer relationship). No prerequisites are stated.

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