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

No annotations are provided, and the description only states what the tool returns. It does not disclose behavioral traits like read-only nature, performance, or any side effects. For a tool with no annotations, the description should carry this burden but fails to do so.

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 sentence that conveys the key information efficiently. While it could be slightly tighter (e.g., removing 'past' if obvious), it is well-front-loaded with 'See past winners' and contains no redundant words.

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 simple read-only nature of the tool with no parameters and no output schema, the description provides sufficient context about what is returned (winners, scores, personality beaten). It could mention ordering or time range, but overall it is fairly complete for a leaderboard tool.

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 has zero parameters and schema description coverage is 100%. With no parameters, the description need not add parameter semantics, and it correctly avoids unnecessary detail. Baseline 4 for zero-parameter tools.

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 'See past winners — who conquered Lucille, their scores, and which personality they beat'. It uses a specific verb ('See') and resource ('past winners'), and distinguishes from sibling tools like 'lucille_my_stats' or 'lucille_history' by focusing on winners and results.

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 this tool is for viewing past winners, but it does not explicitly state when to use it versus alternatives like 'lucille_history' or 'lucille_arena'. No guidance on exclusions or prerequisites is provided.

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