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 the full burden of transparency. It explains the core functionality and pagination parameters, but it does not mention whether the operation is read-only, what happens when no challenges are found, or any potential errors. It also lacks detail on the order of results, which is important for pagination.

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 succinct and well-organized: a one-line summary, a brief explanatory paragraph, and a clear Args section. No unnecessary words or filler, and the structure makes the tool's purpose and parameters easy to scan.

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 tool has a simple getter function with an output schema, so the description does not need to explain the return format. It covers the essential context: what the tool does, which challenges it returns, and how pagination works. The description is complete for an agent to decide when and how to use it.

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 schema only defines 'start' and 'limit' as integers with defaults, but the description adds critical semantics: start is a 1-based index and limit has a max of 100. This goes beyond the schema and provides the information needed to use the parameters correctly.

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 explicitly states that the tool retrieves badge challenges that are currently in progress (not yet completed), distinguishing it from sibling tools like get_badge_challenges (all challenges) and get_available_badge_challenges (joinable ones). It clearly identifies the resource and the specific subset returned.

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 mentions it is 'useful for tracking current progress toward badge goals,' which gives context for when to use it. It does not explicitly name alternatives or state when not to use it, but the purpose is clear enough that an agent can infer appropriate usage from the description and sibling tool names.

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