get_user_preferences

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

With no annotations, the description carries the burden for behavioral disclosure. It implies a read-only operation and scopes to the current user, but it does not mention auth requirements, what happens without a valid access_token, or any side effects. Some basic behavioral context is present, but significant gaps remain.

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, efficient sentence with no filler or redundancy. It is appropriately front-loaded with the core action, though it may be too terse given the missing usage and parameter context.

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 and an output schema exists, but the description lacks usage context, parameter semantics, and differentiation from many sibling tools. With no annotations, this is insufficient for an agent to reliably select and invoke the tool correctly.

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 description coverage is 0% for the access_token parameterainer. The description does not explain how access_token is used, whether it is required, what an empty default means, or how the tool behaves with no token. This is a clear gap given low schema 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?

The description clearly states a specific verb ('Get') and resource ('current user's Reddit preferences and settings'), with explicit user scope. It does not explicitly differentiate from sibling tools like get_reddit_config or other reddit getters, but the operation is understandable.

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?

There is no guidance on when to use this tool versus alternatives, or any context about prerequisites such as authentication. The description does not mention how this relates to or differs from get_reddit_config, get_user_subreddits, or other reddit preference-related tools.

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