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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds only the vague 'recruiting-style search' phrasing and says nothing about how filters combine, whether a default result cap applies, or what happens when a filter is null.

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?

A single front-loaded sentence with no filler, and the filter dimensions are listed in a scannable order. It is concise to the point of under-specification rather than padded.

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?

An output schema exists, so return values need not be described. Still, for a six-parameter filter tool with zero schema coverage, the definition leaves filter-combination semantics, the default 25-result cap, and valid value formats unexplained.

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 description coverage is 0%, so the description must carry parameter meaning; it names position, height, conference and team, which maps loosely onto four of six parameters. It omits 'limit' entirely and gives no value formats (valid position names, conference naming) or explains that height is expressed as min/max in centimeters.

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?

States a specific verb and resource ('Filter players') and enumerates the filterable dimensions (position, height, conference, team), so an agent knows the operation. It does not, however, distinguish itself from the sibling 'search_players' or explain how the two differ.

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 parenthetical '(recruiting-style search)' hints at a use case but never states when to choose this over search_players or get_team_roster. No prerequisites, exclusions, or alternative routing are given.

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