nba_player_info

Read-only

Get NBA player profile. Returns one player's league profile: full name forms, birth date, school and country, draft year and round, jersey number, position, height and weight, team identity and season experience. Take the player id from nba-players or nba-team-roster.

A3.8/5.0
Behavior4/5

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

The annotations already establish that this is a read-only, open-world operation, and the description adds meaningful behavioral context by stating that it returns one player's league profile and listing the categories of information returned. It does not describe error behavior for missing or invalid player ids, but the output schema and annotations cover much of the remaining burden.

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

Conciseness5/5

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

The description is two sentences and is front-loaded with the core action. The field enumeration earns its space by clarifying what the profile includes, and the id-source sentence provides actionable invocation guidance without waste.

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?

Given that an output schema exists and annotations cover the safety profile, the description is complete enough to support correct invocation: it states scope, return content, and where to obtain the required player id. The only notable gap is the lack of explicit guidance distinguishing this from sibling profile or stats tools.

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 description coverage is 100%, so the parameter meanings are already fully documented in the input schema. The description repeats the source of player_id from nba-players or nba-team-roster but does not add new semantics for league_id, so the baseline of 3 is appropriate.

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?

The description uses a specific verb and resource: "Get NBA player profile," and enumerates the returned profile fields. It is clear what the tool does, but it does not explicitly differentiate itself from sibling tools such as nba_player_profile_v2 or nba_player_bio_stats.

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

Usage Guidelines3/5

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

It gives useful invocation context by saying to take the player id from nba-players or nba-team-roster. However, it does not state when to use this profile tool versus the many sibling player-stat and profile tools, so guidance remains implied rather than explicit.

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