app_clip_advanced_experience_images_get_instance

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

No annotations are provided, so the description carries the full burden. The 'GET' verb implies a read-only, non-destructive operation, which is the only behavioral fact conveyed. Nothing is said about authentication requirements, rate limits, or what the returned resource contains.

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 text is short, but the identical endpoint string is duplicated in parentheses, which is pure waste. Brevity here reflects under-specification rather than disciplined conciseness.

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?

With no annotations and no output schema, the description should explain what an app clip advanced experience image is, what the endpoint returns, and any access requirements. It provides none of that, leaving an agent with only the raw path to work from.

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% (both 'id' and 'fields_appClipAdvancedExperienceImages' are documented in the schema, including the enum of includable fields). The description adds nothing about parameters, so the baseline 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 a verbatim restatement of the tool name/endpoint path ('GET /v1/appClipAdvancedExperienceImages/{id}') repeated twice in parentheses. It does encode that this is a single-resource read keyed by id, but it adds no semantic content beyond the name and does nothing to distinguish it from siblings like app_clip_advanced_experience_images_update_instance or 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 when-to-use guidance, no prerequisites, and no mention of alternatives. An agent must infer entirely from the tool name that this fetches one app clip advanced experience image.

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