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

No annotations provided, so description carries full burden. While it explains the business logic (discounts vs cost of capital), it fails to disclose operational traits: whether read-only, return format, side effects, or rate limits.

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?

Extremely concise two-sentence structure. Front-loaded with purpose statement; every word earns its place with no redundancy.

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?

Adequate for a single-parameter analysis tool: explains the parameter and core logic. However, lacking annotations or output schema, it should mention read-only status or return value hints to be 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?

With 0% schema coverage and no parameter descriptions in the JSON schema, the description compensates by explaining 'available_cash' is a budget constraint and clarifying the semantics of the default value 0.

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 action (Find), resource (early-payment discounts), and filtering logic (beat cost of capital) that distinguishes this from general working capital siblings. However, it doesn't explicitly map these distinctions to the sibling list.

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?

Provides only parameter documentation ('0 = show all opportunities') rather than tool selection guidance. No when-to-use/when-not-to-use, prerequisites, or sibling comparison.

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