app_event_screenshots_create_instance

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

No annotations are provided, so the description bears the full behavioral burden, yet it discloses nothing about authentication requirements, side effects, what gets created, or whether the operation is reversible. The HTTP verb POST and the resource path imply a write, but no additional behavioral context 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?

It is short and front-loaded, but the parenthetical repeats the path verbatim, which is pure redundancy rather than earned content. Size is appropriate for what little it says.

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, and no output schema, the description is not complete enough to help an agent build a valid request. It offloads the entire payload contract to an external document without summarizing any required fields or the envelope structure.

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, so the baseline is 3. The description adds a reference to the OpenAPI component (AppEventScreenshotCreateRequest) and the JSON:API envelope, which is useful signposting but not meaning beyond what the schema text already states.

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 effectively a tautology: it repeats the tool name's meaning as an HTTP verb and path ("POST /v1/appEventScreenshots") with the parenthetical duplicated verbatim. It does not state in plain language that it creates an app event screenshot, and it does nothing to distinguish itself from siblings like app_event_screenshots_update_instance, get_instance, or delete_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 when-to-use or when-not-to-use guidance, no mention of prerequisites, and no routing to alternatives (e.g., update vs. create). The only pointer is to the request schema, which addresses payload construction rather than usage context.

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