problem_fetch_codeforces

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

No annotations are present, so the description carries the full burden. 'Fetches... from Codeforces' signals a read-only external lookup, which gives a basic behavioral profile, but it does not disclose potential rate limits, authentication needs, failure modes, or the exact return format. This is adequate but not rich.

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 a single short sentence with no filler. It front-loads the action and names all relevant data categories, making it easy to parse quickly.

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?

The tool is simple, with only two fully documented parameters and no nested objects or output schema. The description identifies the return content categories, which is enough for an agent to call the tool correctly, though it leaves the precise response shape to inference.

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 input schema already provides full descriptions for both parameters, including examples. The tool description adds no parameter-specific detail beyond the schema, so the baseline score of 3 is appropriate.

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 uses a specific verb ('Fetches') and names a concrete resource: Codeforces problem statement metadata, tags, and contest limits. It is immediately clear what the tool does and it does not overlap with any sibling tool in the list, so there is no confusion about its role.

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 clearly implies the tool should be used when an agent needs Codeforces problem metadata, tags, or contest limits. It does not explicitly discuss exclusions or alternatives, but no direct alternative appears among the sibling tools, so the implied usage context is sufficient.

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