get_popular_skills

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

With no annotations, the description carries the full burden for behavioral disclosure, but it only states the action and source. It does not disclose whether this is a read-only operation, how results are ordered, pagination behavior, or any side effects. Minimal behavioral context beyond the basic action.

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 with no filler, making it highly concise. However, it is under-specified in content, leaving out relevant context that could be added without adding wordiness.

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?

This simple tool with two optional parameters and no output schema still lacks important context in the description. It does not explain return format, how 'popular' is defined, the impact of timeframe, or the overall purpose relative to other skills tools. The description is barely above a stub.

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 has 100% coverage for both parameters (limit and timeframe) with descriptions and defaults. The description adds no parameter-specific detail, so the baseline of 3 applies.

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 states a clear action and resource: 'Get popular skills from the leaderboard.' This distinguishes it from siblings like search_skills and get_skill_details by implying a ranked leaderboard source, but it doesn't explicitly differentiate or mention what makes skills 'popular.'

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 provides no guidance on when to use this tool versus alternatives. It does not mention sibling tools, scenarios where this is appropriate, or exclusions. The usage context is only implied by the phrase 'from the leaderboard.'

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