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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses the authentication requirement, which is useful, but it does not explain whether the update is partial or full, how omitted fields are handled, any side effects, or what the response contains. This is insufficient for a mutation 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?

The description is extremely concise—two sentences with no fluff. Purpose is front-loaded, and the authentication note is a single clause. Every word earns 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?

Given eight optional parameters, no output schema, and no annotations, the description is not contextually complete. It omits crucial operational context: whether updates are partial, validation requirements (especially for location), and how this relates to sibling tools like get_my_profile or get_correct_country_name. An agent would need to infer too much.

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 the schema already documents each parameter. The description adds no parameter-specific information beyond what the schema provides, and notably omits guidance on the location constraint (e.g., pointing to get_correct_country_name). Baseline of 3 is appropriate.

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 the verb 'Update' and the resource 'your Himalayas profile', which distinguishes it from company profile updates. It is concise and unambiguous, though it does not explicitly list the fields, relying on the schema for that.

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 only guidance is 'Requires authentication', which is a prerequisite rather than a usage condition. There is no mention of when to use this tool versus alternatives (e.g., get_my_profile for reading, update_company_profile for companies), nor any routing to helper tools like get_correct_country_name for the location field.

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