TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds genuine value by spelling out the relationType vocabulary (PREQUEL, SEQUEL, SOURCE, ADAPTATION, etc.), which tells the agent what the returned links mean before it parses the output schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose is front-loaded, followed by the relation vocabulary and then the prerequisite. The long relation list is dense but each term earns its place by defining output semantics; only minor trimming would be possible.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists and annotations cover the safety profile, so the description needn't explain return structure. It supplies the prerequisite and relation semantics; only a note on behavior when no relations exist (empty list vs. error) is arguably missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%: both `id` and `type` are documented in the schema with an enum for ANIME/MANGA. The description adds nothing about parameter formatting, so baseline 3 is appropriate when the schema carries the load.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("get the anime/manga related to a given title") and enumerates the exact relation types returned. This clearly separates it from siblings like get_media, get_recommendations_for_media, and get_media_characters, which cover adjacent but different data.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly instructs "Use search_media first to resolve a title to its AniList ID," which is the key prerequisite an agent would otherwise miss. No when-not-to-use exclusions are given (e.g., versus get_recommendations_for_media), but the usage context is unambiguous.

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