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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description does add one genuinely useful behavioral fact — that the payload comes back in the provider's raw delimited format rather than parsed structure — but says nothing about pagination, rate limits, or what happens when a view is unsupported for a given match.

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?

A single front-loaded sentence that names the resource first and the view options second. Efficient, though the parenthetical list is dense enough to be slightly harder to parse than a plain scope statement.

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 annotations cover the safety profile. What remains missing is the usage context (match vs tournament standings) and any note on which views apply to which sports, leaving the definition merely adequate for a 2-parameter tool.

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%, so the baseline is 3. The description's parenthetical view list (over-under, HTFT, live, top-scorers) is a looser shorthand than the schema's exact enum values (overunder_overall, htft_home, etc.), so it adds no precision 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?

States a specific verb+resource: retrieves a match-linked standings/table view, and the parenthetical enumerates the available views. It implicitly distinguishes itself from the tournament-level siblings (flashscore_tournament_standings), but it never names them, so the differentiation is left to inference.

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?

There is no when-to-use guidance at all. With siblings like flashscore_tournament_standings and flashscore_tournament_standings_views, the agent gets no signal about which standings tool to pick for a given task, nor any prerequisites.

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