app_encryption_declarations_create_instance

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

With no annotations, the description carries the full behavioral burden, yet it discloses nothing about authentication requirements, idempotency, side effects, or what the POST actually creates. The endpoint line conveys no behavioral trait beyond the verb already in the name.

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 definition is short but wasteful: the endpoint is printed twice in immediate succession with no added information in the parenthetical. It is not front-loaded with any meaningful purpose statement.

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 create tool with no annotations, no output schema, and a nested JSON:API body that must be constructed correctly, the description is far too thin. Only the OpenAPI component reference offers any help, leaving field requirements, required relationships, and return behavior unexplained.

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% for the single body parameter, so the schema already documents it, and the description merely points to the same OpenAPI component (components.schemas.AppEncryptionDeclarationCreateRequest). Baseline 3 is appropriate since the schema does the heavy lifting with no added semantic detail.

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 the HTTP endpoint restated verbatim, duplicated in parentheses, and adds no resource semantics beyond what the tool name already implies. It never explains what an app encryption declaration is or what creating one accomplishes, making it near-tautological.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternative or related calls such as app_encryption_declarations_get_collection or app_encryption_declaration_documents_create_instance. Only the HTTP POST method faintly implies a create operation.

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