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

Annotations already declare readOnlyHint and openWorldHint, lowering the bar, and the description adds real context: results are paginated and returned as host-free slugs rather than full URLs. It does not mention rate limits or auth, but for a safe read-only directory that is acceptable.

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?

Two sentences, front-loaded with the action and scope, and the second sentence gives the return shape plus the follow-on tool. Every clause earns its place with no filler.

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?

With an output schema present, explaining return values is unnecessary, and the description still summarizes them (paginated host-free slugs). For a simple no-required-param listing tool this is nearly complete, though pagination defaults and category value format remain unspecified.

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 burden. It partially compensates by naming the two category values and implying pagination (limit/offset), but it never clarifies the slug format, default page size, or how category strings must be spelled, leaving meaningful parameter ambiguity.

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?

States a specific verb (List), a precise resource (complete Sportskeeda NBA player-query directory), and the two scoping categories (Player Stats / Player vs Team). It also names the follow-on sibling sportskeeda_page_data, so an agent can distinguish this directory-list tool from the stats-table tool without opening a schema.

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 clearly routes the workflow: list slugs here, then pass a slug to sportskeeda_page_data for the stats table. This is strong context, but it does not explicitly contrast this tool against other sportskeeda siblings (e.g. player_stats, page_options) or state when it should be preferred over them.

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