retrieve_user_is_password_set

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds only the HTTP endpoint and the note that this concerns an idm user; it says nothing about the return shape or error behavior when the user is unknown.

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?

Short and front-loaded with the target resource. The endpoint tag and the second sentence partially duplicate each other, but nothing is bloated enough to impede selection.

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?

For a trivial two-parameter read this is close to sufficient, and annotations plus schema carry most of the load. The gap is the undocumented return value — a boolean status flag — which is left completely implicit since no output schema exists.

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 100% with only two parameters, both self-documented (userId and the trace header). The description adds no syntax, format, or defaulting information beyond what the schema already provides, so the baseline 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 second sentence states a specific check: whether an idm user's password is set, with the endpoint path confirming a GET read. It is clear enough to distinguish from generic retrieve_user, though the first sentence is an awkward near-restatement of the tool name.

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?

No indication of when to prefer this over siblings such as retrieve_user, or what a caller should do with a false result (e.g., call reset_password). The reader must infer the usage context entirely.

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