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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that results come back as several result sets and that the breakdowns are computed upstream, which meaningfully warns the agent to expect a multi-set payload rather than a flat table. It says nothing about data freshness, failure modes for unverified leagues, or what happens with the default season.

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 single sentence is duplicated verbatim, and the opening 'Get Returns' is a garbled artifact, so roughly half the text is wasted. The substantive content is short and front-loaded, but the duplication and malformed verb hurt readability.

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, and the schema documents all five parameters. What remains missing is the surrounding context an agent needs: whether team_id is effectively mandatory in practice, what 'several result sets' means for consumption, and how this differs from the player-level counterpart. Adequate but with clear gaps for a dashboard-style tool.

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 coverage is 100%, so every parameter is already documented in the schema, and the baseline is 3. The description only adds that the dashboard is for a single team, implicitly reinforcing team_id, but it gives no extra meaning about per_mode or season_type semantics beyond what the schema states.

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 text names a specific resource (one team's passing dashboard) and scopes the output as pass-type breakdowns returned as several result sets, which is more specific than the tool name alone. However it is mangled by the 'Get Returns' prefix and the identical sentence repeated twice, so it reads as boilerplate rather than a crisp verb+resource statement, and it never explicitly contrasts itself with the player-level sibling.

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?

There is no when-to-use guidance: nothing says when a team pass-type dashboard is the right choice over nba_player_dash_pt_pass or the other team dashboards. The only implicit signal is 'one team's', which hints at team scope but stops short of routing the agent.

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