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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description's burden is lighter. It still adds real context beyond them: the data source and volume, the 'same tour only' restriction on the forecast range, and that the surface parameter scopes only the forecast and rally plan.

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 first clause is well front-loaded, but the remainder is one long comma-spliced list of deliverable nouns that is hard to scan. Given the absence of an output schema the length is defensible, yet the single-sentence enumeration lacks structure.

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?

With no output schema, the description usefully enumerates the plan's contents (forecast, serve/return maps, rally preferences, style compatibility, charted head-to-heads) so an agent knows what comes back. Parameter coverage is handled by the schema, so the definition is essentially complete for a two-required-parameter read 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 description coverage is 100%, so the schema already documents player, opponent, and the surface enum with its default. The description adds only 'Optionally for one surface', which restates what the schema says, so the baseline 3 applies.

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 opens with a precise verb+resource statement ('A scouting game plan for one player against an opponent') and quantifies the underlying corpus (11,822 charted ATP/WTA matches), so the agent knows exactly what it produces. It does not, however, name or distinguish itself from the siblings get_player, explain_match, or get_leaders, leaving that routing to inference.

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?

Usage is only implied: the matchup-framing and the explicit note 'same tour only' for the forecast hint at when the tool is appropriate, and 'Optionally for one surface' signals scoping. There is no statement of when to prefer it over get_player or explain_match, and no exclusions or prerequisites.

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