A3.6/5.0

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 profile is covered. The description adds that the thread's title, body and metadata (replyCount, viewCount, likeCount, isLiked) are returned, which is modest extra context — though most of that duplicates the output schema. It says nothing about authentication (isLiked is user-relative) or error behavior for missing/deleted threads.

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?

One sentence, front-loaded with the verb and resource, then the returned fields. Zero padding or redundant phrasing.

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?

With an output schema covering return values, full parameter documentation, and annotations carrying the read-only/open-world profile, the description supplies enough for correct invocation. The only gap is that it doesn't flag that this is a read sibling of delete_thread/search_thread or mention auth-sensitive fields.

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 description coverage is 100%: the single 'id' parameter is fully documented in-schema, including how to obtain one and URL examples. The description only restates 'by its ID' and adds no syntax or constraint detail beyond the schema, so baseline 3 applies.

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

Purpose4/5

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

States a specific verb ('Get') and resource ('AniList forum thread') plus the retrieval key ('by its ID'), so the operation is unambiguous. It doesn't contrast itself with the sibling search_thread inside the description text, leaving sibling differentiation to the schema.

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

Usage Guidelines3/5

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

'By its ID' implies this is a direct lookup rather than a search, which hints at when to use it versus search_thread. However, the explicit routing advice ('use search_thread to find one') lives only in the parameter schema, not the description, so the guidance in the description itself is implied rather than stated.

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