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

With no annotations, the description carries the behavioral burden. It discloses that the data is 'public' and that this is a read/overview operation, and it lists the output categories. It does not mention authentication needs, rate limits, or failure behavior, but for a simple read-only profile tool this is a reasonable but not rich disclosure.

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?

The description is compact and front-loaded with the tool's purpose. The opening 'LiveScore player profile.' is somewhat redundant with the tool name, but the main sentence efficiently enumerates the returned data without wasted words.

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?

For a single-parameter, read-only tool with no output schema, the description provides enough context to call it correctly: it explains where the path comes from and what the response will contain. The phrase 'when supplied' is slightly ambiguous, but it does not prevent correct invocation.

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?

The input schema already provides 100% coverage of the single 'path' parameter, including the expected format 'season-stats/player-slug/numeric-player-id'. The description adds only marginal context by mentioning the team-squad source, so it does not significantly improve on 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?

The description uses a specific verb and resource: it 'Returns the public overview profile data for a player' and lists the main content areas. It is clear and distinct from sibling tools like livescore_team or livescore_match, though it does not explicitly name an alternative to differentiate against.

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 implies when to use the tool: when you have a public LiveScore player link, especially one 'linked from a team squad'. However, it provides no explicit exclusions or comparisons to alternative player-profile tools such as fotmob_player or sofascore_player.

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