Get Seasonal Anime

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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds value by detailing the return format (compact text table plus structured content with fields like year, season, total_returned, offset, has_more, entries including picture). It also explains sort behavior and season definitions, going beyond annotations.

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 consists of two concise sentences. The first states the core purpose, and the second adds essential details on seasons, sorting, and return structure. Every sentence provides actionable information without redundancy.

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 5 parameters and no output schema, the description sufficiently explains the output structure and paging. It covers typical use cases but omits edge case behavior (e.g., invalid year). With annotations providing safety context, the description is complete enough for effective tool use.

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 60% (3 of 5 params have descriptions). The description adds meaning beyond the schema: it explains season enum values with month ranges (winter=Jan-Mar, spring=Apr-Jun, etc.) and clarifies sort values (anime_score desc or anime_num_list_users desc). This compensates for the undocumented params.

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 the tool fetches anime that aired in a specific broadcast season, with the verb 'fetch' and resource 'seasonal anime'. It distinguishes from siblings like search_anime and get_anime_ranking by specifying season-based filtering.

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 explains when to use the tool (to get anime by season) but does not provide explicit guidance on when not to use it or alternatives. Sibling tool names imply differentiation, but the description lacks direct usage context.

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