app_store_version_experiment_treatments__update

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description adds the HTTP method PATCH, which hints at partial update semantics, but it does not disclose other behavioral details such as required permissions, whether changes are reversible, or what happens to unspecified fields. With annotations carrying the safety profile, this is adequate but not rich.

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 description is a single sentence plus the endpoint path. It is front-loaded with the action and resource, contains no redundant information, and every word earns its place.

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 simple update tool with detailed schema and annotations, the description is minimally adequate. However, there is no output schema, and the description does not explain response behavior or any side effects beyond 'update'. This leaves some ambiguity for the agent, though the schema fills most gaps.

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%, with the id described as 'ID from the matching list call' and the body as a JSON:API request. The description itself adds no parameter-specific meaning, so the baseline score of 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 clearly states 'Update an App Store version experiment treatment' with a specific verb and resource. The endpoint path [PATCH /v1/appStoreVersionExperimentTreatments/{id}] further confirms the action, and the name distinguishes it from sibling create/delete/get tools for the same resource.

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?

The use case is implied: the tool updates an existing treatment. However, no explicit guidance is given on when to use it versus alternatives, nor does it mention prerequisites (e.g., that the id must come from a list call, though the schema provides that hint). There are no exclusions or alternative tool references.

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