app_clip_header_images__update

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

Annotations provide idempotentHint=true and destructiveHint=false but the description adds no behavioral context (e.g., side effects, permission needs, or confirmation of idempotency). Does not leverage the opportunity to explain what updating entails beyond the schema.

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?

Extremely concise (one sentence + endpoint), but at the expense of useful detail. Front-loaded with the action and resource, yet lacks any structured guidance like parameter hints or usage notes.

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 output schema, the description does not explain return values or success indicators. For a 2-parameter tool with a nested body, more context (e.g., response type, idempotency behavior, partial vs full update) is needed to make the tool self-contained.

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% and descriptions in the schema are self-explanatory (e.g., 'Resource identifier.'). The description adds no additional parameter meaning or usage context beyond what the schema already provides, warranting baseline score.

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?

Description clearly states the verb 'Update' and the resource 'an App Clip header image', making the action and target unambiguous. The endpoint path [PATCH /v1/appClipHeaderImages/{id}] reinforces the HTTP method, distinguishing it from create, get, and delete siblings.

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 guidance on when to use this tool over alternatives (e.g., create, delete). Lacks prerequisites, context of use, or conditions under which an update is appropriate. The agent is left without decision support.

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