sdcloud_update_user

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

Without annotations, the description carries full behavioral disclosure burden. It indicates a mutation ('Update') but fails to describe side effects, authorization requirements, or whether the operation is idempotent. No details on the impact of the 'body' parameter.

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 (one sentence). While it front-loads the purpose, it omits important details, making it under-informative. It could be longer to cover semantics and usage.

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 the lack of annotations, output schema, and a freeform body parameter, the description is insufficient. It does not specify whether the update is partial or full, what the response contains, or any constraints on the body.

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 coverage is 50% (user_id lacks description in schema, body has a generic description). The tool description adds no meaning beyond the schema; 'by user_id' is redundant. It does not clarify the format or constraints for the body object.

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 'a user', with the identifier 'by user_id'. It distinguishes this tool from sibling tools like create_user, get_user, delete_user, and list_users.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, such as whether the user must exist, or what fields are updatable. No comparison to create_user or change_password is given.

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