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

Annotations already establish readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds one genuinely useful behavioral detail: results come back as 'several result sets' rather than a single table, which tells the agent to expect multiple result sets. It does not mention that team_id is effectively required despite the schema listing zero required parameters, nor does it cover rate limits or errors.

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?

Two sentences, front-loaded with the action and resource, with the return-shape detail second. Nothing is redundant, though the second sentence slightly restates the first before adding the 'several result sets' information.

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 enumerated, and the description still usefully flags the multi-result-set shape. Parameters are fully documented in the schema. The main gap is the absence of usage routing among many similar team dashboards, but for a single-purpose read tool this is largely complete.

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 100%, so every parameter (season, team_id, per_mode, league_id, season_type) already carries its own meaning, examples, and defaults. The description adds no parameter-level information beyond the resource scope. Baseline 3 is appropriate when the schema does the heavy lifting.

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 description names a specific verb and resource ('Get NBA team rebound dashboard') and scopes it to one team, with the breakdown types (rebound-type, distance-range) spelled out. It implicitly distinguishes itself from nba_player_dash_pt_reb by saying 'one team's', but it does not explicitly contrast itself with the other team-level dashboards listed as siblings.

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 description gives no when-to-use context, no prerequisites, and no mention of alternatives. An agent has to infer that this is the team-level counterpart to nba_player_dash_pt_reb, and it has nothing to distinguish it from nba_team_stats or nba_team_dash_by_game_splits. That is no guidance rather than implied guidance.

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