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

No annotations are provided, so the description carries full burden for behavioral disclosure. It discloses nothing about return format, pagination behavior, authentication needs, rate limits, or side effects. The description is purely categorical and fails to reveal any behavioral traits.

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 extremely brief (one line) but is under-specified, not concisely informative. It front-loads only a category and billing note, omitting essential functional details. For a tool with 7 parameters, this is far too sparse to be considered well-structured.

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 the tool's complexity (7 parameters, no annotations, no output schema), the description is completely inadequate. It provides no information on what the tool returns, how to use the parameters, or when to choose it over similar subreddit post tools. The description fails to make the tool usable without external knowledge.

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 0%, and the description adds no meaning to the 7 parameters (show, after, count, limit, before, sr_detail, subreddit). The example values in the schema (e.g., 'politics' for subreddit) are the only hints, and the description provides no parameter explanations or usage context.

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 name and title imply it retrieves rising posts from a subreddit, but the description is a categorical label ('Subreddit Posts > Rising') and billing info, restating the title without a clear verb+resource statement. It adds no functional purpose beyond what the name suggests, and does not differentiate it from siblings like get_subreddit_hot or get_subreddit_new.

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 provides no guidance on when to use this tool vs alternatives. It does not mention context, prerequisites, or exclusions, leaving the agent to guess based solely on the name and sibling list.

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