get_available_badge_challenges

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

No annotations are provided, and the description only states the action. It fails to disclose any behavioral traits such as side effects, authentication requirements, or rate limits. The description carries the full burden but is insufficient.

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 overly terse. While concise, it lacks necessary detail for a tool with two parameters and no annotations, resulting in under-specification that harms usability.

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 numerous sibling tools with similar names, the description should clarify what 'available' means and how it differs from 'get_badge_challenges' or 'get_adhoc_challenges'. The lack of output schema also misses an opportunity to inform the agent about return values.

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% (both 'limit' and 'start' have descriptions). The tool description adds no additional meaning beyond the schema, so baseline of 3 is appropriate.

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 'Get available badge challenges to join' is a clear verb+resource but essentially restates the tool name without adding nuance or differentiating from siblings like 'get_badge_challenges' or 'get_adhoc_challenges'. It is minimally adequate but lacks specificity.

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?

No guidance on when to use this tool vs alternatives. There is no mention of prerequisites, exclusions, or contexts where this tool is appropriate compared to similar badge-related tools.

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