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

No annotations exist, so the description carries the full disclosure burden. It usefully reveals the returned components and the accent-folding behavior (Chloé becomes CHLOE), which sets expectations for input normalization, but says nothing about error behavior for non-Latin characters, whether the computation is deterministic, or the exact response shape.

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?

Two sentences, front-loaded with the input-output contract, followed by one concrete example. Nothing is wasted and nothing essential is buried.

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?

For a single-parameter, read-only calculation tool with no output schema and no annotations, the description is nearly sufficient: it names the returned values and clarifies normalization. It falls short only in not sketching the structure of the per-letter trail, which an agent may need to interpret the result.

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 coverage is 100%, so the single 'name' parameter, its length bounds, and accent folding are already documented in the schema. The description's example input adds only marginal value beyond that baseline.

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 states a specific verb (takes a name) and resource (name in Latin letters) and enumerates exactly what is returned: Chaldean destiny number, compound number, and per-letter trail. An agent can distinguish it from lifePath, loShuGrid, and compatibility because the input is a name rather than a birth date or grid, though no sibling is named explicitly.

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?

Usage is implied rather than stated: an agent can infer this is the name-based numerology calculation, and the example input models a call. There is no explicit when-to-use, when-not-to-use, or pointer to a sibling tool for other numerological calculations.

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