conversion_parity_bit

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

No annotations are provided, so the description carries the full burden. It mentions step-by-step calculation but does not disclose any side effects, required inputs format, or error handling behavior.

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 two sentences, clearly front-loading purpose. However, the reference to describe_tool adds a minor distraction but does not detract significantly from conciseness.

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 the lack of parameter explanations and no output schema, the description is incomplete. It does not specify what the input format should be or what the output represents, leaving the agent without enough context to use the tool effectively.

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?

The input schema has three required parameters (mode, input, parityType) with no descriptions, and the description itself provides no explanations for any parameter. With 0% schema description coverage, the description fails to compensate.

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 tool calculates parity bits for error detection, listing supported parity types (even, odd, mark, space) and noting step-by-step calculation. This distinguishes it from sibling tools, none of which are parity bit 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 only advises using 'describe_tool with tool_id parity' for full guidance, but does not specify when to use this tool versus alternatives, nor does it provide context for when parity bit calculation is appropriate.

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