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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is a retrieval operation (implied read-only) and mentions the return data structure, but does not cover important aspects like error handling, rate limits, authentication requirements, or whether the data is cached/real-time. It adds some value but lacks comprehensive behavioral 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?

The description is efficiently structured with a clear purpose statement followed by Args and Returns sections. Every sentence earns its place by providing essential information without unnecessary elaboration. The front-loaded purpose statement immediately communicates the tool's function, making it highly scannable and zero-waste.

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 moderate complexity (single parameter read operation), the description provides adequate context: purpose, parameter meaning, and return data overview. With an output schema present (as indicated in context signals), the description appropriately doesn't need to detail return values. However, it could better address behavioral aspects like error cases or data freshness given the lack of annotations.

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 description explicitly defines the single parameter 'team_id' as 'The CTFtime team identifier', adding crucial semantic meaning beyond the schema's basic type (integer). With 0% schema description coverage and only one parameter, this definition fully compensates for the schema gap, providing clear parameter context without redundancy.

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 'Retrieve' and the resource 'detailed information about a specific CTF team', making the purpose specific and unambiguous. It distinguishes this tool from siblings like get_top_teams (which lists multiple teams) or get_event_details (which focuses on events rather than teams), establishing clear differentiation.

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 usage when detailed team information is needed, but does not explicitly state when to use this tool versus alternatives like get_top_teams or search_events. No guidance is provided on prerequisites, exclusions, or specific contexts where this tool is preferred over others, leaving usage somewhat inferred rather than explicitly defined.

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