get_latest_livescores

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

No annotations are provided, so the description carries the full burden. It clearly states that the tool returns livescores updated in the last 10 seconds, which implies a read-only operation. While it does not mention authentication, rate limits, or output details, the core behavior is transparent and non-misleading.

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 a single sentence that contains no redundant words. It is concise and front-loaded, conveying the essential purpose immediately. Every word earns its place.

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?

The description adequately explains the tool's core function for a simple listing endpoint. However, it omits details about output structure, error handling (e.g., no updates returns empty), or ordering. Given no output schema, slightly more context would be helpful, but it's minimally complete.

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?

All 5 parameters are fully described in the input schema (100% coverage). The description adds no additional parameter details, so the baseline score of 3 applies. The schema descriptions are sufficient for basic meaning.

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 clearly states the action ('Get'), the resource ('livescores'), and the specific scope ('that received updates within the last 10 seconds'). This precisely distinguishes it from sibling tools like get_all_livescores (all livescores) and get_inplay_livescores (in-play only).

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 usage when recent livescore updates are needed, but it does not explicitly state when to use this tool versus alternatives (e.g., get_all_livescores, get_inplay_livescores) or provide any exclusion cases. The context of time-based filtering is clear, but no comparative guidance is given.

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