updateProfile

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only says 'Update' without explaining whether updates are partial or full replacements, whether the operation is destructive, or whether any validation occurs.

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 short and front-loads the main purpose, with the parameter clarification placed second. It is efficient, though the brevity comes at the cost of omitting other parameter semantics.

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?

With four parameters, no output schema, and no annotations, the description is too sparse to fully support correct invocation. It explains only one parameter and provides no return or update-behavior context, leaving significant gaps for an agent.

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 0%, so the description must compensate for the schema's silence. It explains max_talk_time_ms with a concrete example, but provides no meaning for name, profile_image_url, or default_sip_number, leaving three of four parameters semantically unexplained.

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 states a clear action ('Update') and resource ('profile fields'), so an agent can tell this tool is for modifying profile data. It doesn't explicitly differentiate from sibling update tools like updateAgent, but 'profile' provides enough distinctness in this context.

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 guidance on when to use this tool versus alternatives. No conditions, prerequisites, or exclusions are mentioned, leaving the agent to infer that it should be used whenever a profile update is needed.

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