fpl_get_manager_transfers_by_gameweek

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

Annotations already declare readOnlyHint=true and idempotentHint=true. Description adds behavioral details: return format (complete transfer history with costs), error handling (invalid team ID, no transfers, API failure). Does not contradict annotations.

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?

Well-structured with sections: main description, usefulness, requirements, args, returns, examples, error handling. Concise and front-loaded: first sentence states core action.

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 two parameters and schema coverage, description covers all necessary aspects: purpose, parameters, return type, error handling, and examples. No gaps identified.

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 descriptions cover both parameters well. Description adds examples (team_id=123456, gameweek=20) and explains how to obtain team_id from FPL URL, providing extra context beyond 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?

Description clearly states action: 'Get all transfers made by a specific manager in a specific gameweek.' Specifies resource (transfers), constraints (manager and gameweek), and details shown (players in/out, costs, timing). Distinguishes from siblings such as fpl_analyze_transfer and fpl_get_manager_squad by focusing on transfers per gameweek.

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?

Explains usefulness ('analyzing manager strategy') and prerequisite ('Requires manager's team ID (entry ID) which can be found in the FPL URL'). Does not explicitly exclude alternatives or list when not to use, but provides enough context for appropriate selection among siblings.

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