getUserProfileByUserId

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

No annotations are present, and the description merely restates the action of fetching profile data. It lacks details on authentication, return format, error behavior, or side effects, which is minimal given the tool's read-like nature.

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 a single, front-loaded sentence with no waste. It efficiently communicates the core action, though barely, and earns full credit for conciseness.

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 no output schema and no annotations, the description should clarify what profile fields are returned, possible errors, or how to interpret the data. The current text is too sparse for an agent to make downstream decisions based on the response.

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% for the single parameter, so the description adds little beyond echoing 'use user ID'. No additional format, constraints, or contextual meaning is provided, aligning with the baseline for fully covered schemas.

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 tool retrieves personal profile data for a ShenDao platform user by user ID. It uses a specific verb and resource, and distinguishes from sibling tools focused on maps, comments, lists, and social relations.

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 guidance is given on when to use this tool versus the many sibling get*ByUserId tools. It neither provides context for selection nor mentions exclusions or alternatives.

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