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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds useful behavior beyond them: the feed is independent of any match ID and returns raw delimited text, which tells the agent about the unusual return encoding. It doesn't cover auth or rate limits, so not a full 5.

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?

Purpose and scoping constraint are front-loaded in the first clause, and the second sentence handles routing efficiently. It is dense with semicolons but every clause earns its place; slightly heavy but not wasteful.

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 description still notes the raw delimited format and the match-ID independence. An agent has everything needed to call it correctly; minor omitted details (auth, pagination) keep it below 5.

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 schema already documents the path example (premier-league), the /standings/ exclusion, and common view values. The description nods at path and view but adds no format or syntax detail beyond the schema, so the baseline 3 holds.

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 (Fetch) and resource (competition-level Flashscore standings or top-scorer table) scoped by path and view. It explicitly distinguishes itself from flashscore_match_standings and flashscore_tournament_standings_views, so an agent can select it without opening the 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?

Names both relevant alternatives and the condition that selects each: use the views tool to discover valid views, and use flashscore_match_standings for a match-linked table. This is explicit when/when-not routing rather than implied usage.

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