get_non_completed_badge_challenges

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

No annotations are provided, so the description carries full burden. It does not disclose safety implications (read vs write), pagination behavior beyond parameter names, rate limits, or any side effects. The agent is left to assume it's a safe read operation without confirmation.

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 fluff. It is concise but could benefit from additional context to justify its brevity. The structure is front-loaded with the action, which is good.

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 lack of output schema and many sibling tools, the description is insufficient. It does not clarify what 'not completed' means (e.g., includes not started or only in-progress?), and no return format is described. The agent must guess the exact output structure.

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?

Schema description coverage is 100%, with both 'limit' and 'start' described in the schema. The tool description adds no additional meaning beyond the schema, so the baseline of 3 applies. The description could have explained how these parameters work together (e.g., pagination details).

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 what the tool does: get badge challenges that are not completed. It uses a specific verb ('get') and resource ('badge challenges'), but it does not differentiate from similar sibling tools like 'get_in_progress_badges' or 'get_available_badge_challenges', which could overlap in meaning.

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. There is no mention of prerequisites, typical use cases, or explicit comparisons to sibling tools. The lack of context forces the agent to infer usage from the name alone.

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