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

No annotations provided, so description must disclose behavior. It correctly conveys a read operation without side effects. Does not elaborate on authentication, scope, or potential empty results. Sufficient for a simple tool but lacks depth.

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?

Single Japanese sentence that is concise and immediately understandable. No extraneous words. Front-loaded with purpose.

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?

No output schema exists, but description does not specify return format or structure. With siblings suggesting a dictionary context, the description is adequate but could benefit from mentioning that it returns a list or what each entry contains.

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?

Tool has no parameters, so schema coverage is 100%. Description adds value by explaining the output scope (all entries, English words and readings), which is more informative than the empty schema alone. Appropriate for a zero-parameter tool.

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?

Description clearly states the action (listing) and resource (English words and readings from custom dictionary). It differentiates from siblings add_to_dictionary, remove_from_dictionary, and say by describing a read-only retrieval. No ambiguity.

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 context is implied: when you need to view dictionary contents. However, no explicit guidance on when to use vs alternatives, nor conditions like requiring dictionary population first. Adequate but not explicit.

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