C2.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered and the description carries a lighter burden. It adds only the season-wide scope, saying nothing about pagination, the effect of the optional 'dates' value, or how the calendar is returned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One short, front-loaded sentence with the verb first and no filler or repetition. It is appropriately sized, though it is arguably too terse for a three-parameter tool rather than wordy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema and no parameter documentation, so the description is the only source of meaning, and it does not explain what the returned calendar looks like or how 'dates' scopes it. For a league-wide schedule tool with an open-world hint, this leaves real gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must supply the meaning of 'sport', 'league' and especially the optional 'dates' argument, whose format (single date? range? season string?) is entirely undefined. The description mentions a season but adds no format, no defaults, and no required/optional distinction, leaving every parameter undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete verb ('Fetch') and resource ('league schedule calendar and active event dates across a season'), which is enough to tell it apart from team-scoped siblings like games_get_team_schedule. However, it never names that sibling or any other alternative, so the differentiation is left to inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no when-to-use guidance, no exclusions, and no alternatives. With near-identical siblings such as games_get_team_schedule and games_get_league_events in the same namespace, an agent has to guess which one to pick.

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