get_mlb_standings

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

With no annotations provided, the description carries full burden but only partially discloses behavioral traits. It mentions default values and parameter purposes, but doesn't cover important aspects like rate limits, authentication needs, error conditions, or pagination behavior. The description adds some context but leaves significant gaps.

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 well-structured with a clear purpose statement followed by organized parameter documentation. While efficient, the parameter explanations could be slightly more concise. Every sentence serves a purpose, and the information is front-loaded appropriately.

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's moderate complexity, 6 parameters with 0% schema coverage, and no annotations, the description does a good job explaining parameters and return values. However, with an output schema present, the return value explanation is somewhat redundant, and behavioral aspects like error handling remain undocumented.

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?

Given 0% schema description coverage, the description fully compensates by providing clear semantic explanations for all 6 parameters. Each parameter gets specific guidance on format, acceptable values, defaults, and purpose, adding substantial value beyond the bare 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 clearly states the specific action ('Get current MLB standings') and resource ('for a given season'), distinguishing it from siblings like get_mlb_schedule or get_mlb_teams. It precisely identifies what the tool does without being vague or tautological.

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 context through parameter explanations (e.g., 'Defaults to current year'), but lacks explicit guidance on when to use this tool versus alternatives like get_mlb_teams or get_mlb_schedule. No when-not-to-use scenarios or sibling comparisons are provided.

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