jp_lit_search_illustrations

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

No annotations are provided, so the description carries the full burden. It mentions the search scope (公開範囲のみ) and that results include IIIF image URLs (page and cropped). However, it does not disclose rate limits, authentication needs, caching behavior, or error handling.

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 two sentences, front-loaded with purpose, and no redundant words. Every sentence adds value.

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 has 4 parameters, no annotations, and an output schema (not shown), the description is incomplete. It lacks explanations for pagination parameters (from, size) and caching control (force_refresh). It covers scope and output format but not behavior or parameter details.

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%; the description does not explain the meanings of 'size', 'from', or 'force_refresh'. Only 'keyword' is implied by the description text. The description fails to compensate for the lack of schema parameter descriptions.

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 searches illustrations (図版・挿絵) in the NDL Digital Collection by text keyword, limited to public domain materials. This differentiates it from sibling tools like jp_lit_search_pages and jp_lit_search_fulltext.

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?

The description implies usage for searching illustrations but does not explicitly state when to use this tool versus alternatives like jp_lit_search_pages or jp_lit_search_fulltext. No exclusions or preconditions are provided.

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