update_messaging_profile

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

With no annotations, the description carries the burden. It discloses configurable behaviors (e.g., enabling/disabling, webhook settings) but does not clarify update semantics (partial vs. full replacement), authentication requirements, or side effects. The return type is only vaguely stated as 'Dict[str, Any]'.

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 lengthy but well-organized with a clear parameter list and field explanations. It is front-loaded with the main purpose and each line adds necessary detail for a complex update operation. No redundant fluff.

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 no annotations and no output schema, the description is quite complete for invoking the tool. It explains all parameters and their types. The only gap is the minimal return description and lack of error scenarios.

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 schema only provides profile_id and a generic request object with 0% coverage. The description compensates by detailing all request fields and their meanings, including nested settings like number_pool_settings and url_shortener_settings. This adds immense value 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 description clearly states 'Update a messaging profile' with a specific verb and resource. It naturally distinguishes from sibling tools like create_messaging_profile and get_messaging_profile.

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 implies usage by listing all updatable fields but does not explicitly state when to use this tool versus alternatives (e.g., create vs update). It gives no exclusions or prerequisites.

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