Get Group Standings

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

Annotations already provide readOnlyHint=true, so behavioral safety is clear. The description adds that before the tournament starts it returns pre-tournament strength ratings, but does not specify what happens during or after the tournament, nor does it mention data freshness or update frequency.

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 tightly packed with all essential information: purpose, behavior before tournament, filtering options, and group range. No wasted words, and key details are front-loaded.

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 no output schema, the description explains what is returned (power rankings/strength ratings) and the basis (FIFA rankings, betting odds, predictions). It covers the main use case but does not detail the structure of the output (e.g., list of teams with numeric scores).

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%, providing a baseline of 3. The description adds value by specifying that groups are A-L and that omitting the parameter returns all 12 groups, as well as explaining that results include ratings based on FIFA rankings, betting odds, and predictions.

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 verb 'get' and resource 'standings' (group power rankings) for the FIFA World Cup 2026. It distinguishes itself from sibling tools like 'get_groups' by specifying it returns rankings rather than just group information.

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 explains that the tool can filter by group (A-L) or return all 12 groups, providing clear context for when to use the optional parameter. However, it does not explicitly contrast with siblings like 'compare_teams' or 'get_historical_matchups', which could also involve ranking data.

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