calculate_current_yield

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

The description clearly states the calculation formula, making the tool's behavior transparent. No annotations exist, but the tool is a pure mathematical function with no side effects; however, an explicit statement of 'no side effects' would improve transparency.

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 a single concise sentence that conveys the essential formula with no unnecessary words, perfectly front-loaded.

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 defines the core purpose but omits parameter details and usage context. Given the presence of an output schema and the tool's simplicity, it is minimally adequate but not fully comprehensive.

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?

Parameter meaning is only implied by the formula; no description clarifies units (e.g., annual coupon as dollars or decimal, market price as dollars). With 0% schema description coverage, the tool description fails to compensate adequately.

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 explicitly states the formula 'Current Yield = Annual Coupon / Market Price × 100', clearly identifying the tool's purpose and distinguishing it from sibling tools like YTM or bond price calculators.

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 use for computing current yield but provides no guidance on when to use this tool versus alternatives (e.g., YTM for total return) or what inputs are appropriate.

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