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

The description reads as a pure retrieval of name attributes (gender, meaning, etymology, market-day alignment), yet annotations declare readOnlyHint=false, destructiveHint=true, idempotentHint=false, and openWorldHint=true — an agent cannot tell whether calling this mutates state. The description does add useful return-content detail beyond the annotations, but discloses nothing about permissions, side effects, or result 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?

A single front-loaded sentence that opens with the verb and resource before enumerating the returned attributes. The parenthetical example list and attribute list are dense but each item contributes domain specificity; no filler sentences.

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?

With no output schema, the description does describe the returned fields well (gender classification, philosophical meaning, morphemic etymology, market-day alignment). It leaves gaps on result shape (single record vs. list), no-match behavior, and — critically for destructive-annotated tooling — whether the call is safe to repeat.

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 100% and both parameters are documented, so the schema carries the parameter burden. The description adds domain framing for the 'name' input (given vs. baby vs. compound 'Aha Igbo' names) but says nothing extra about the optional gender filter's accepted values or matching behavior.

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 verb ('Look up') and a well-bounded resource ('traditional Igbo personal given names, baby names, and full compound names / Aha Igbo') with concrete examples ('Adaeze', 'Chidubem', 'Okeke'). The domain boundary implicitly separates it from siblings like lookup_nsibidi, search_proverbs, and calculate_market_day, but 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?

There is no when-to-use or when-not-to-use guidance and no named alternative. An agent must infer from the examples that this is the name-ontology lookup rather than search_dictionary or search_lineage, and nothing says what to do if the name is not found or whether partial matches are supported.

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