beta_app_review_details_update_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, yet it discloses nothing behavioral: not whether this is a partial or full replacement, what permissions are required, what fields are mutable, or whether changes are reversible. Pointing to an external OpenAPI schema is not behavioral disclosure within the definition.

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, which is good, but the entire content is a raw endpoint restated twice in parentheses, which is pure waste, and it defers substantive content to an external schema reference. Front-loaded but not informative.

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 tool with no annotations and no output schema, the definition should explain what the update affects and any prerequisites, but it only supplies an endpoint and an external schema pointer that the agent cannot necessarily resolve. Critical context for correct invocation is missing.

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%, so the two parameters (id, body) are already documented in the schema, and the baseline for a well-covered schema is 3. The description only names the external request schema type for the body, adding no field-level meaning beyond the schema.

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 HTTP method (PATCH) plus the resource path identify this as an update to a beta app review detail resource, and the tool name corroborates that. However, the purpose is never stated in plain language and the endpoint is written twice redundantly, so an agent gets the verb+resource only by decoding the path. No differentiation from 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?

There is no guidance on when to use this update tool versus the many sibling update tools (app_store_review_details_update_instance, in_app_purchase_versions_*, etc.), no prerequisites, and no mention of the beta app review detail lifecycle. The agent must infer usage entirely from the name.

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