beta_app_localizations__update

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false. The description adds only the HTTP method (PATCH) and endpoint, which weakly implies partial update semantics, but it does not disclose side effects, required permissions, or behavior on omitted fields. No contradictory statements.

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 clean sentence plus endpoint, with no filler words. Every element contributes to identifying the tool's purpose and HTTP binding.

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?

Given a straightforward update operation with rich annotations (idempotent, non-destructive) and a fully documented schema, the minimal description is adequate. It lacks any statement about the response shape or side effects, but for this simple tool, the provided structure is sufficient.

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?

The input schema fully documents both parameters: id ('ID from the matching list call') and body ('JSON:API request body (Apple schema)'). The tool description itself adds no parameter meaning, but schema coverage is 100%, so the baseline 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 uses the specific verb 'Update' and names the resource 'beta app localization', clearly distinguishing it from sibling tools like create/delete/get/list. The appended endpoint '[PATCH /v1/betaAppLocalizations/{id}]' reinforces the precise action.

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 description provides no guidance on when to use this tool versus alternatives (e.g., create for new localizations, get for reading). It does not mention prerequisites like needing an ID from a list call, nor does it exclude any scenarios. The only implicit signal is the verb 'Update'.

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