get_player_context

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

With no annotations provided, the description carries the full burden of disclosing behavior. It states what data is returned, implying a read operation, but does not mention side effects, data freshness, error states, or any restrictions. The list of return types provides some transparency, but not enough for a fully informed decision.

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 description is a single, front-loaded sentence that directly conveys the core functionality. It contains no filler or redundant information, making it highly concise and well-structured.

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?

Given the tool's simplicity and the presence of an output schema, the description covers the essential return components. However, the lack of usage guidance and parameter clarification means it is not fully complete, but it is adequate for a straightforward context retrieval 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?

The schema has 0% description coverage, and the description does not elaborate on the player_id parameter. While it says 'for a player', it does not specify the expected ID format, source, or any mapping nuances (e.g., how to obtain a valid player_id). The description fails to compensate for the bare schema.

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 clearly states the tool returns player context comprising specific data types (projections, market inputs, injuries, news). It uses the verb 'Return' and identifies the resource (player context), which distinguishes it from sibling tools like get_league_overview or get_season_context.

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 implies the tool is for retrieving comprehensive player-level data, which is distinct from league-level or sync-focused sibling tools. However, it does not explicitly state when to use it over alternatives or provide exclusion criteria, so it lacks explicit guidance.

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