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

No annotations are provided, so the description must disclose behavioral traits. It states 'FREE endpoint' and that 'Feedback is used to optimize pricing decisions,' but does not clarify if the tool is read-only, whether it stores data, or any side effects. The mutation behavior is unclear.

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 short (two sentences) and front-loaded with key information. However, the phrase 'FREE endpoint' at the start is slightly off-topic and could be integrated or removed for better clarity.

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 description covers the tool's purpose and a usage condition, but given the absence of an output schema and annotations, more context would be helpful, such as what the tool returns or whether it is a one-time suggestion.

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 documentation covers all 4 parameters with descriptions, achieving 100% coverage. The tool description does not add further meaning to the parameters beyond the schema, so a baseline score of 3 is appropriate.

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's purpose: to suggest a target price for a paid endpoint when current pricing is too high. The verb 'suggest' and resource 'endpoint price' are explicit, and the tool is distinct from sibling tools which are mostly informational or security-related.

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 a condition for use ('If a paid endpoint's pricing is too high') but does not mention alternatives or when not to use. Among siblings, no other tool handles pricing suggestions, so usage guidance is implied but not explicit.

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