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

With no annotations, the description carries the full burden. It mentions 'clean and under noise' and 'replay' but does not disclose whether this is a read-only operation, what exactly is returned, or any side effects. The behavior is implied but not explicit.

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 (one sentence), but it is not well-structured for clarity. The key information about ranking and strategies is buried in poetic phrasing, and the sentence does not front-load the primary purpose.

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 description is incomplete for a simple read tool. It does not specify the output format, prerequisites (like needing to have entered a tournament), or any limitations. The mention of replaying matches is vague and could mislead an agent about the tool's capabilities.

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 tool has zero parameters, so the baseline is 4. The description does not need to add parameter meaning, and the schema already covers everything (trivially). No compensation is required.

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 is vague and poetic, using 'The table' without a clear verb or explicit statement of the operation. It implies ranking by points and showing strategies, but does not clearly say 'get standings' or 'retrieve leaderboard'. It fails to distinguish from sibling tools like tournament_enter.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention that one must enter a tournament first, nor does it contrast with tournament_enter or other related tools. No context for selection is provided.

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