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

No annotations provided, so description carries full burden. It mentions 'FREE' and 'no payment needed', which is behavioral, but does not disclose auth needs, rate limits, or side effects. For a simple feedback tool, it is adequate but lacks depth.

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?

Two concise sentences with no redundant information. Every phrase adds value: 'FREE', 'after using our signals', 'score 1-10 plus pros and cons'.

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 no annotations, no output schema, and simple tool, description covers purpose and key parameters. However, it does not clarify whether pros/cons are optional or required (schema shows only score required), leaving minor gaps.

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?

With 0% schema coverage, description compensates by mentioning score range (1-10) and pros/cons fields. This adds meaning beyond the schema, but does not detail parameter types or constraints fully.

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 is a feedback tool for rating after using signals, specifying the verb 'leave a rating' and the resource 'score 1-10 plus pros and cons'. It distinguishes from siblings like 'evaluate_symbol' which focus on symbol analysis.

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 implies usage after using signals ('after using our signals'), providing context but not explicit when-not-to-use or alternatives. While siblings differ, no direct comparison is made.

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