A4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and openness profile is covered. The description adds useful specifics about what the call returns (relation types and type) but does not cover edge cases like empty results or invalid IDs. This is comparable to baseline value 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.

Conciseness5/5

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

Two concise sentences with zero redundancy: the first states the tool's function and output, the second gives the prerequisite. The most important scoping information is front-loaded before the usage note.

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?

For a simple two-parameter tool with full schema coverage, an output schema present, and read/open-world annotations, the description provides the necessary purpose, output shape, and prerequisite. It is not exhaustive about edge cases, but nothing essential to correct invocation is 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% and both parameters have descriptive definitions, so the schema carries the meaning. The description adds a small workflow hint that the ID comes from search_media, but it does not add syntax, format, or enumeration details beyond the schema. Baseline 3 applies.

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?

The description uses a specific verb ('Get') and resource ('anime/manga related to a given title'), enumerates the relation types (prequels, sequels, side stories, adaptations, spin-offs), and clarifies it includes the relation type. This clearly distinguishes it from sibling tools like get_media_characters or get_media_reviews.

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?

The description explicitly directs the agent to 'Use search_media first to resolve a title to its AniList ID', establishing a clear prerequisite workflow. It does not name exclusions or compare against alternative tools, but the sequential use case is unambiguous.

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