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

Without annotations, the description carries the burden and discloses key behavioral traits: the output is synthesized (not recorded), approximately IPA, and explicitly labeled as not a native speaker. This candid limitation is valuable for an agent. However, it does not mention permissions, rate limits, or error 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 a single, efficient sentence that front-loads the tool's purpose and appends a useful honesty disclaimer. No wasted words, though the parenthetical could be seen as slightly dense.

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 simple one-parameter tool with no output schema or annotations, the description covers the core function and its limitations. It still lacks usage context (when to use vs siblings) and detailed parameter semantics, leaving an agent with some uncertainty.

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%, so the description must compensate. It implies the parameter accepts a transliteration or word, but adds no format constraints or examples beyond that. The schema's maxLength and type are undocumented in the description. Baseline 3 is appropriate when schema provides some structural info but description adds minimal semantic detail.

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 (synthesized pronunciation guide), the resource (respelling + approximate IPA), and input scope (transliteration or word). It clearly distinguishes itself from siblings like define or lookup by focusing specifically on pronunciation.

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 explicit when-to-use guidance or mention of alternatives (e.g., define or lookup). The internal tag suggests restricted use, but no conditions for selection are provided.

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