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

No annotations exist, so the description must cover behavioral traits. It states the tool computes numbers and provides meanings, but does not mention edge cases (e.g., invalid characters in name), whether it modifies anything (it shouldn't), or any rate limits. It is adequate but not thorough.

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 sentence that front-loads the key outputs (Expression/Destiny, Soul Urge, Personality numbers) and is concise with no wasted words.

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 tool's simplicity (1 param, no output schema), the description is mostly adequate but fails to differentiate from siblings or clarify what 'with meanings' implies for the output. It lacks context on prerequisites or example usage.

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%, and the description only says 'from a name' without elaborating on what constitutes a valid name (e.g., full name, treatment of spaces, case sensitivity). The parameter 'name' is not explained beyond its type.

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 it computes specific numerology numbers (Expression/Destiny, Soul Urge, and Personality) from a name using the Pythagorean method with meanings. It is a specific verb and resource, and distinguishes from siblings like life_path which is likely about birth date numbers.

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 explicit guidance on when to use this tool versus alternatives like compatibility, life_path, or numerology_profile. The context is implied but no when-not or exclusion criteria are given.

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