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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and openWorld, so the safety profile is covered externally. Beyond that the description only offers the opaque terms 'black-box' and 'public', explaining neither what 'black-box' means, how entries are ranked/ordered, nor how pagination behaves for a paged list.

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?

A single front-loaded sentence with no padding, which is appropriately sized for the task. The only wasted token is the unexplained 'black-box' qualifier.

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?

An output schema exists, so return values need not be described. But for a paginated, four-parameter list tool with two enums and many rival leaderboard/reputation tools, the description gives no ordering, no pagination semantics, and no sibling disambiguation.

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?

With 50% schema description coverage, the role and period descriptions merely restate their enum values, and limit/offset are undocumented. The phrase 'by canonical role' does add a little meaning — signalling that role partitions the leaderboard — but it says nothing about limit, offset, or period defaults.

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 gives a clear verb+resource ('List ... reputation leaderboard entries') and scopes it by role, so an agent knows the operation. However, it never distinguishes itself from the near-identical sibling problee_list_leaderboard, which an agent could easily pick instead.

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 explicit when-to-use guidance and no mention of alternatives such as problee_list_leaderboard, problee_get_my_reputation, or problee_get_season_standings. Usage must be inferred entirely from the tool name.

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