get_earned_badges

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

No annotations are present, so the description carries full burden. 'Get' implies a read-only operation, but the description does not disclose whether it returns the current user's badges, whether authentication is required, or any filtering/ordering/pagination behavior. Minimal beyond the operation itself.

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?

A single concise sentence with no filler, front-loads the operation and resource. It earns its place despite lacking detail.

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 is simple, has no parameters, and an output schema exists, so full return documentation is not needed. However, the description is thin: it fails to clarify the implicit user scope (current user?) and gives no routing signal among the many badge-related siblings. Adequate for a trivial getter but with clear gaps.

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?

There are zero parameters, so the schema provides no target information. The description adds the concept of 'user' as the scope of the query, which is meaningful; however, it leaves unspecified whether this means the authenticated user, which is a minor ambiguity. Baseline for 0 params is 4.

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 clear verb ('Get') and resource ('earned badges') and implies a user scope, so an agent can identify the operation. It doesn't explicitly differentiate from sibling badge tools like get_badge_challenges or get_available_badge_challenges, but the 'earned' qualifier distinguishes it from challenge/available lists.

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 call this vs alternatives; no exclusions or context. The tool name and siblings imply a decision between earned badges, available challenges, and non-completed challenges, but the description does not state it.

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