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

Annotations already cover the safety profile (readOnlyHint, openWorldHint), and the description adds useful context beyond them: the article is 'public' (no auth/privacy barrier) and the call returns both metadata and body rather than a summary. It stops short of describing pagination or error behavior.

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?

One sentence, front-loaded with the action and resource, with the input origin appended at the end. Nothing is wasted.

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?

An output schema exists, so return values need not be elaborated, and the description already signals the return covers metadata plus body. For a single-parameter read tool the definition is essentially complete, though it could mention slug format edge cases.

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 0%, so the description must carry the parameter, and it does: it explains that the slug is a 'host-free path_slug' obtained from sportskeeda_wiki_pages, which is more than the undifferentiated 'slug' string in the schema conveys.

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?

Names a specific verb (Fetch), resource (public Sportskeeda Wiki article), and scope (metadata and body), and distinguishes itself from the sibling sportskeeda_wiki_pages by pointing to it as the source of the slug rather than as a rival.

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?

States the precondition for use, that the slug comes from sportskeeda_wiki_pages, which tells the agent this is the follow-up call to a page listing. It does not, however, name any explicit when-not-use condition or alternative detail-fetching sibling.

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