espn_nfl_scores

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

No annotations are provided, and the description offers minimal behavioral information beyond the obvious read operation. It does not disclose data freshness, format, or potential limitations. For a tool with no annotations, the description should provide more context about what 'current' means and how the data is structured.

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, concise sentence that directly conveys the tool's purpose without extraneous information. It is efficiently front-loaded and uses precise language.

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?

Given the tool has no parameters, no output schema, and a simple task, the description is largely complete. However, it could be slightly improved by mentioning the scope (e.g., 'all current NFL games' or 'weekly scores'), but the current description is adequate for a straightforward data lookup.

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 tool has zero parameters, and the description adds the meaning that scores are 'current', implying time-sensitive data. According to the rubric, 0 parameters yields a baseline of 4. The description adds value by indicating the temporal scope.

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 verb 'Get', the resource 'current NFL scores', and the source 'from ESPN'. It distinguishes this tool from sibling tools like espn_nba_scores and espn_mlb_scores by specifying the sport (NFL).

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 provides no guidance on when to use this tool versus alternatives (e.g., espn_news for news, espn_team_info for team details, or other sports score tools). There is no mention of context or exclusions.

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