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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to repeat safety. It adds valuable behavioral context by specifying 'recent' and listing return fields (headline, date, author, excerpt). No contradictions with annotations.

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 three concise sentences, each earning its place. It front-loads the core purpose, then usage context, then prerequisite. No extraneous 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?

For a two-parameter tool with no output schema, the description adequately explains what the tool does and what it returns. It could mention pagination limits, but the schema already describes page as optional. Overall, complete for its simplicity.

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 coverage is 100% with clear descriptions for both parameters (id: 'MyAnimeList numeric ID.', page: '1-based page number for pagination'). The description adds context by explicitly calling id the 'mal_id' and linking to search_anime, which goes beyond the schema.

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 lists recent news articles for a specific anime by mal_id, specifying return fields (headline, date, author, excerpt). It distinguishes itself from sibling search_anime by directing the agent to obtain mal_id from there, leaving no ambiguity about its unique function.

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 explicitly states it is useful for 'what's new / any announcements' questions, providing clear context for when to use. It also instructs how to get the required mal_id via search_anime. No explicit when-not-to-use or alternatives are needed given no sibling news tool exists.

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