Fetch Baseball Savant catcher pop-time leaderboards by season, team, and minimum steal attempts, returning ranked catchers with arm, exchange, and caught-stealing metrics.

Instructions

Get Baseball Savant Catcher Pop Time leaderboard. Returns catchers ranked by pop-time metrics, filtered by season, team, and minimum steal attempts to second or third. Sort and pagination are applied locally.

TDQS

B3.2/5.0
Behavior3/5

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 usefully discloses that 'Sort and pagination are applied locally,' which tells the agent how limits/offset behave, but it says nothing about auth requirements, rate limits, or what an empty/error response looks like.

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?

Three tight sentences with the purpose front-loaded, then filters, then the local sort/pagination note. Nothing is redundant, though the closing clause could carry more weight if it explained pagination semantics.

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

Completeness4/5

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

For an 8-parameter, zero-required read-only leaderboard tool with no output schema, the description covers purpose, filterable dimensions, and local sort/pagination behavior, which is generally sufficient. Minor gaps remain around defaults for limit/offset and the identity of the 'mlb_discovery' referenced by the sort field.

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

Parameters3/5

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

Schema coverage is 100%, so every parameter (sort, year, limit, min2b, min3b, offset, team_id, sort_dir) is already documented in the schema with enum values. The description only restates the filter concepts (season, team, min attempts), adding no syntax or format detail beyond the schema.

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 specific verb ('Get') and resource ('Baseball Savant Catcher Pop Time leaderboard'), plus the dimensions it ranks by. It is clear what the tool returns, though it does not distinguish itself from near-siblings like mlb_statcast_catcher_throwing or mlb_statcast_catcher_framing.

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 lists the filter dimensions (season, team, minimum steal attempts) but offers no explicit when-to-use or when-not-to-use guidance, and never names an alternative among the many mlb_statcast_* siblings. Usage is only inferable from the resource name.

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