beta_build_localizations_create_instance

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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing about authentication/scopes, side effects, idempotency, or what is created. Only the bare fact of a POST operation is conveyed via the route, which is minimal transparency for a mutating tool.

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 and front-loaded with the endpoint, which is good. However, the parenthetical '(POST /v1/betaBuildLocalizations)' is a redundant duplication of the leading text, so the sentence does not fully earn 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?

This is a create/mutation tool with no annotations, no output schema, and an opaque nested body object with no enumerated properties. The description should compensate with auth requirements, expected request envelope shape, or return behavior, but it provides none of these.

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% and there is a single body parameter, so the baseline is 3. The description points to components.schemas.BetaBuildLocalizationCreateRequest, but this duplicates the schema's own body description and adds no field-level meaning beyond the opaque free-form object.

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 only echoes the HTTP method and endpoint path ('POST /v1/betaBuildLocalizations'), which restates the tool name rather than stating in prose what the tool does. An agent must infer from the name that this creates a beta build localization, and no sibling differentiation is offered despite dozens of near-identical *_create_instance tools.

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, when-not-to-use, prerequisite, or alternative guidance. It does not tell the agent how this differs from beta_build_localizations_update_instance or the other create_instance siblings, leaving selection entirely to inference.

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