analyze_lease

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

No annotations are provided, so the description carries full burden. It mentions a price ('$3.00'), which is useful cost information. However, it doesn't disclose critical behavioral traits: whether this is a read-only analysis or has side effects, what permissions are needed, rate limits, processing time, or what happens with incomplete lease terms. The description is insufficient for a mutation-sensitive operation.

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 appropriately concise with three clear sections: purpose statement, args explanation, and returns statement. The price information is efficiently included. However, the 'Args' and 'Returns' labels are redundant since structured fields exist, and the description could be more front-loaded with critical behavioral information.

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 1 parameter with 0% schema coverage and no annotations, but with an output schema present, the description is moderately complete. The output schema means return values don't need explanation. However, for a tool that analyzes complex lease terms, the description should provide more guidance on input expectations, analysis methodology, and limitations to be fully complete.

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%, so the description must compensate. It mentions 'lease_terms: Lease details including rent, term, location, size' which provides some semantic context about expected fields. However, with 1 parameter that's a nested object with additionalProperties, this minimal guidance is inadequate - it doesn't specify required vs optional fields, data formats, or validation rules.

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: 'Analyze commercial lease terms and market comparison.' It specifies the verb ('analyze'), resource ('commercial lease terms'), and scope ('market comparison'). However, it doesn't differentiate from sibling tools, which appear to be unrelated financial/crypto tools rather than direct alternatives.

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 provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, appropriate contexts, or exclusions. While sibling tools seem unrelated, the description offers no usage context beyond the basic purpose statement.

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