Search subreddits

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

With no annotations, the description bears full burden for behavioral traits. It only states the search action and purpose, omitting any details about return format, pagination, sorting, rate limits, or authentication. This leaves the agent with minimal behavioral context.

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 sentence that is front-loaded with the action and purpose. Every word is necessary, and no extraneous information is present. Extremely concise and 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 absence of annotations and output schema, the description is incomplete. It does not specify what data is returned (e.g., subreddit names, descriptions, subscriber counts), how results are ordered, or any pagination. An agent would lack crucial context to interpret and use the tool's response.

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%, meaning the description must compensate. However, it does not explain the query and limit parameters beyond their names. While the parameter names are somewhat self-explanatory, the description adds no additional meaning, leaving the agent without guidance on formatting or constraints.

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?

Description clearly states the tool searches Reddit communities by query, with a specific purpose of finding audience fit before posting. This verb+resource combination effectively distinguishes it from siblings like get_subreddit_rules or submit_text_post.

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 a clear context (finding audience fit before posting) that implies when to use this tool, but does not explicitly state when not to use it or compare with alternatives. Sibling tools have distinct purposes, so the usage is reasonably well-guided.

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