anilist_taste_card

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

Annotations already indicate readOnlyHint=true and destructiveHint=false, so the tool is non-destructive. The description adds value by specifying the output is a PNG image containing specific visual elements (genres, themes, etc.). It does not contradict annotations and provides useful behavioral context.

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 long, front-loaded with the primary action and output format. Every sentence contributes meaning: first sentence states what it does and output format, second sentence gives use case. No unnecessary words.

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 only two optional parameters, readOnlyHint annotation, and no output schema, the description fully explains what the tool returns (a PNG with taste profile visualizations). It covers the essential behavioral and output details for an agent to invoke correctly.

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?

The input schema has 100% description coverage for both parameters ('username' with fallback info, 'type' with anime/manga enum). The description text adds no further parameter-level detail beyond mentioning 'score distribution' which relates to output, not parameters. The baseline of 3 is appropriate as the schema already explains the parameters.

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 taste profile card image, specifying it returns a PNG with top genres, themes, score distribution, and format breakdown. This distinguishes it from sibling tools like anilist_compat_card (compatibility card) and anilist_taste (text-based taste info).

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 says 'Use when someone wants a visual summary of their anime taste.' This provides clear context but does not explicitly state when not to use it or list alternative tools. However, given the sibling list, it is adequate for guiding typical use.

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