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

Annotations declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so safety and idempotency are already covered. The description adds transparency by enumerating the specific outputs of the review, but does not disclose return format, pagination, or error behavior. With annotations carrying the safety burden, a 3 is appropriate for the added output context.

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?

A single, well-structured sentence that front-loads the core action and then lists the review components. No redundant or filler content.

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?

For a read-only review tool with full parameter coverage and annotations covering safety, the description gives a complete picture of what the tool returns. The only minor gap is lack of explicit guidance on when to prefer this tool over alternatives like rate_my_team or get_my_team, but given the specific output enumeration, this is a relatively small omission.

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 both parameters ('gw' and 'team_id') are fully described in the schema itself, including defaults and input formats. The description adds no parameter-level detail beyond what the schema provides, so 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?

States a specific verb+resource (review a manager's gameweek) and lists exact deliverable components: points vs average, captain result, bench points, transfers, and luck vs expected points. Distinguishes from siblings like get_manager_squad or rate_my_team, which do different things.

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 when to use it (post-gameweek review) but does not explicitly state when NOT to use it or name alternatives. No routing guidance like 'use get_manager_squad for raw squad data' is provided.

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