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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds the useful non-auth detail ('免登录'), but says nothing about what the returned analysis contains or how the three parameters shape it.

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?

A single compact sentence covering both purpose and benefit, with the key qualifier '免登录' front-loaded. No filler, though it is arguably too terse to be fully front-loaded with actionable context.

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?

The tool is simple and read-only with annotations covering safety, and all parameters are optional. However, with no output schema and 0% parameter coverage, the description leaves the shape of the returned analysis and the effect of each parameter unexplained.

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% and the description provides no parameter information at all. The enum values for caseId are self-describing, but detail ('standard' vs 'evidence') and scenario are left entirely to inference.

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?

States a specific verb (读取/read) and resource (模拟人物的综合分析 — a simulated persona's comprehensive analysis), and adds the qualifier 免登录 (no login required). This distinguishes it from get_user_profile and get_assessment, though it never explicitly names those siblings.

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?

Implies usage through '免登录' and '体验不同特点和状态下的建议' — i.e. use it to preview/demo suggestions when no authenticated profile is available. No explicit when-not conditions or named alternatives are given, so the agent must infer.

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