beta_app_clip_invocation_localizations_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 behavioral burden. It only implies mutation via the PATCH verb (partial-update semantics) and otherwise says nothing about permissions, reversibility, partial-vs-full update behavior, or which fields are mutable, deferring everything to an external OpenAPI document.

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 route is duplicated verbatim in parentheses with no added information, which is pure waste. The one substantive clause (body shape reference) could have been stated once and front-loaded, but instead the definition leads with redundant boilerplate.

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 mutation tool with no annotations, no output schema, and a nested free-form body object. The description should clarify the JSON:API envelope, updatable fields, or auth requirements, but instead it points to an external document an agent cannot read, leaving the definition inadequate for correct invocation.

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 both parameters are already documented in the schema. The description repeats the body schema pointer that the schema itself already provides, adding no new syntax, constraints, or field-level meaning, 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 identifies the HTTP method and full route (PATCH /v1/betaAppClipInvocationLocalizations/{id}), so an agent can infer this updates a beta app clip invocation localization resource. However, it never states the purpose in plain language or distinguishes it from the sibling create/delete instance tools; it is essentially a mechanical endpoint restatement.

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 indication of when to use this tool versus beta_app_clip_invocation_localizations_create_instance or delete_instance, no prerequisites, and no mention of required scopes or IDs. The agent must infer usage entirely from the name and route.

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