beta_app_clip_invocation_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, side effects, whether the created localization is immediately live, or error behavior. It only hints that the body must be a JSON:API envelope, which is a marginal addition over the schema's own pointer.

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-loads the endpoint, but the parenthetical repeats the identical POST path verbatim, which is pure waste. The remaining sentence adds little value, so it is compact but not efficient.

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, no output schema, and a nested opaque object body, the definition is far from complete: it never explains what a beta app clip invocation localization is, what it attaches to, or what the caller should expect. It effectively defers entirely to an external OpenAPI document the agent may not have.

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 nested 'body' parameter whose shape is already documented by the referenced schema component. The description's note about the 'full JSON:API envelope' adds a small amount of framing but no field-level semantics, 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 gives an HTTP verb and resource path (POST /v1/betaAppClipInvocationLocalizations), from which an agent can infer 'create a beta app clip invocation localization'. However, it never states the purpose in prose and does not distinguish itself from the sibling update_instance/delete_instance beyond the HTTP method, so an agent must infer intent from naming conventions.

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 guidance, no prerequisites, and no mention of alternatives such as beta_app_clip_invocation_localizations_update_instance or delete_instance. The agent is given no criteria for choosing this tool over its siblings.

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