faceit_getChampionshipGroupRanking

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

With no annotations, the description carries the full burden. It discloses the HTTP endpoint, parameters with constraints, and return type. However, it does not detail ordering criteria or authentication requirements, which is acceptable for a read operation.

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 concise with a clear one-line purpose, usage guideline, endpoint, parameter list, and return statement. It is front-loaded with no redundant information.

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?

While the description covers parameters adequately, it lacks detail on the return value beyond 'Championship ranking'. Given no output schema, more explanation of the ranking structure (e.g., list of players, fields) would enhance completeness.

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 0%, but the description adds detailed parameter descriptions, types, constraints (e.g., min, max), and defaults. This compensates fully, providing meaning beyond the schema titles.

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 retrieves the group ranking of a championship, specifying the verb 'Retrieve' and the resource 'group ranking of a championship'. It distinguishes from sibling tools like faceit_getChampionshipLeaderboards by focusing on a specific group's ranking.

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 explicitly states when to use the tool: when you have a championship_id and a group number and want the full ordered ranking. It provides clear context but does not explicitly mention when not to use or list alternatives.

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