app_clip_header_images_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, and it discloses nothing: no auth/permission requirements, no side effects, no mention that this is a mutating create, no return shape. A bare endpoint string is all that is offered.

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 already-terse text wastes its one clause by duplicating the same POST path in parentheses. It is under-specified rather than concise, so brevity here is not a virtue.

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 a nested JSON:API body, no annotations, and no output schema, the definition should at least enumerate the required attributes or confirm the return envelope. Delegating everything to an unnamed external schema leaves the agent unable to construct a valid call.

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% for the single body parameter, which sets a baseline of 3, but the description's only parameter content is an external pointer ('see OpenAPI components.schemas.AppClipHeaderImageCreateRequest') that the agent presumably cannot dereference. It adds no inline meaning about required attributes of the JSON:API envelope.

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 only restates the HTTP verb and path ('POST /v1/appClipHeaderImages'), which is a tautology of the tool name rather than a statement of what is being created in domain terms. An agent learns no more about the resource than it could infer from the identifier app_clip_header_images_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?

There is no guidance on when to use this tool, what prerequisites exist, or how it relates to the sibling app_clip_header_images_get_instance / update_instance / delete_instance tools. Nothing steers selection.

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