anilist_seasonal_recap_card

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is clear. The description adds that it returns a PNG image, which is key behavioral information beyond annotations. However, it does not mention external API calls or any other side effects.

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, followed by a concise list of content. Every sentence adds value without redundancy or filler. Ideal structure.

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 low complexity (3 optional params, 100% schema coverage, annotations present, no output schema), the description covers purpose, output format, and default behaviors. No gaps for typical use cases.

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 descriptions are present for all three parameters and are enriched by the description, which explains fallback behavior for username, default season, and default year. This adds value beyond the schema, clarifying defaults that are not enumerated.

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 generates a shareable seasonal recap card image for an AniList user, listing specific content (pick/finish/drop counts, hit rate, etc.). This clearly identifies the tool's function and distinguishes it from siblings like anilist_seasonal (list data) or anilist_wrapped_card (yearly recap).

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 does not provide guidance on when to use this tool versus alternatives like anilist_seasonal or anilist_wrapped_card. There is no mention of prerequisites, preferred contexts, or exclusions, leaving the agent without explicit usage guidance.

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