subscription_group_submissions_create_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, yet it discloses nothing about auth requirements, side effects, or rate limits. It only notes the operation is a POST and where the body schema lives, which is minimal disclosure.

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 but wasteful, duplicating the path in parentheses and then deferring entirely to an external schema reference. It is not front-loaded with any actionable information.

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 tool with no annotations, no output schema, and a body shape referenced only externally, the description leaves too much unexplained. It does not state what fields the request requires or what the creation affects.

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 there is a single body parameter whose schema already points to components.schemas.SubscriptionGroupSubmissionCreateRequest. The description repeats the same pointer, adding no meaning beyond the schema, so the baseline of 3 applies.

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 is essentially a restatement of the tool name and URL ('POST /v1/subscriptionGroupSubmissions'), which is a tautology rather than an explanation. It conveys that the tool creates a subscription group submission but does not explain what that resource is or distinguish it from sibling creators like subscription_submissions_create_instance.

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 when-to-use, prerequisites, or alternative tools are mentioned. The sibling list contains numerous *_create_instance tools, and nothing here helps an agent choose among them.

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