get_inprogress_virtual_challenges

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

With no annotations, the description carries the full burden of behavioral disclosure. It provides important runtime details: the pagination start index must be >= 1, the limit max is 100, and a version-specific note that garminconnect 0.3.2 rejects 0. The read-only nature is implied by 'Get/Returns' but not explicitly declared, and rate limits or error behavior are not discussed.

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 compact and well-structured: a one-sentence purpose statement followed by a concise Args list. Every sentence provides actionable information, including a practical version-specific warning, with no fluff or repetition of schema defaults.

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?

For a simple read-only endpoint with two optional parameters and an output schema present, the description covers the essential usage: what the tool returns, what param constraints exist, and how pagination works. The only missing element is explicit guidance on when to use this over sibling challenge tools, which is already acknowledged in the usage dimension.

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 provides types and defaults for the two parameters. The description adds essential meaning: start is a pagination index with a lower bound, limit is the maximum number of challenges with a max cap, and a real-world compatibility quirk about start=0. This fully compensates for the 0% schema description coverage.

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?

States a specific action ('Get') on a specific resource ('in-progress virtual challenges/expeditions') and defines what qualifies: challenges the user is currently participating in. This clearly sets it apart from sibling tools like get_badge_challenges or get_adhoc_challenges, which target different challenge types.

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 clearly conveys the intended use: retrieve virtual challenges the user is currently participating in. However, it does not explicitly mention alternatives or provide when-not-to-use guidance, so it stops short of full routing instructions.

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