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 open-world profile is covered. The description adds only the word 'public' as behavioral context; it says nothing about result limits, ranking, or matching behavior. With annotations carrying the burden, a 3 is appropriate.

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 short, front-loaded sentence with no filler, and the entity scope is stated up front. It is efficient, though extremely terse for a search entry point.

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 explained, and the one-param schema is self-documenting. However, for a search tool that feeds a large family of flashscore detail endpoints, the description gives no hint about what the results contain or how to continue, leaving the workflow implicit.

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 description coverage is 100% and the single required parameter 'q' is fully documented in the schema (2-80 characters). The description adds no syntax or format guidance beyond what the schema provides, so the baseline 3 applies.

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 clear verb (search) and resource (entities) with a scope enumerating the entity kinds: teams, players, and tournament templates. An agent can tell this is an entity-lookup search rather than a scores/standings tool, though it does not explicitly differentiate itself from near-neighbors like flashscore_top_search or flashscore_navigation.

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?

Usage is implied by the word 'search' and the enumerated entity types, but the description offers no explicit when-to-use conditions or alternatives. It never says, for example, to prefer this for resolving a name before calling flashscore_team or flashscore_match_info, leaving routing to inference.

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