mlb_teams_stats

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

No annotations provided, so description must disclose behavior. It mentions return format but no details on idempotency, authentication needs, rate limits, or error handling. The agent lacks critical behavioral context.

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?

Two sentences plus a return format snippet are concise and front-loaded. However, the return format could be integrated more cleanly to save space.

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?

With no annotations or output schema, description should cover parameter meanings, prerequisites, and behavior. It addresses purpose and sorting but lacks completeness for a 6-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 coverage is 0%, yet description only hints at sortStat and limit. Key parameters like group, stats, and sportId are not explained. The description adds minimal meaning beyond the schema itself.

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?

Description explicitly states 'Aggregate stats across all teams — league-wide team leaderboard by season + group' and mentions sorting/limiting. This clearly differentiates from siblings like mlb_team_stats or mlb_leaders, which target specific teams or players.

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?

Description implies usage for league-wide team stats but does not explicitly state when to use or not use alternatives. Siblings like mlb_team_stats exist, but no direct guidance is provided.

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