B3.4/5.0
Behavior3/5

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

With no annotations, the description must carry behavioral disclosure. It does communicate a read-only listing operation with sort, limit, and time filtering, but it does not discuss output behavior, auth requirements, rate limits, or how defaults affect results beyond the listed defaults.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact, front-loaded with the main action, and organized as a clear args list. Every line contributes useful parameter or behavioral information, with no filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema covers the return shape, so that is not a gap. However, given six sibling tools focused on specific Reddit feeds, the description does not clarify how reddit_front relates to them or when it should be chosen, leaving meaningful selection ambiguity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the 'Args' block is the only source of parameter meaning. It provides allowed values for sort and time_filter and defaults for all three parameters; only limit is described thinly as 'Posts to fetch' without min/max constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear action and resource: 'Get Reddit front page posts.' It is readable and the args define sort, limit, and time_filter, but it does not actively distinguish itself from siblings like reddit_hot, reddit_top, or reddit_new.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance about when to use reddit_front versus reddit_hot, reddit_top, reddit_new, or other sibling tools. The sort options imply flexibility, but no criteria, exclusions, or alternative recommendations are provided.

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