reddit_subreddit_about

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

No annotations are provided, so the description must disclose behavioral traits. It discloses that subscriber counts, icons, and banners are omitted due to anonymous access limitations. However, it does not discuss authentication, rate limits, error handling, or whether the tool works only for public subreddits.

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?

Two sentences, no waste. The first sentence front-loads the purpose, and the second adds essential limitation context. Every word is meaningful and efficient.

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?

For a simple tool with two parameters and no output schema, the description provides adequate context: what it returns, what is omitted, and how to use the limit parameter. It could be enhanced by describing the return structure, but given the tool's simplicity and detailed schema, it is nearly complete.

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 coverage is 100%, so the schema already clearly defines both parameters. The description adds no additional meaning beyond the schema; it mentions 'sample posts' which aligns with the limit parameter, but does not elaborate on return format or metadata fields.

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 it retrieves subreddit metadata and sample posts, with specific verb 'Get' and resource 'Reddit subreddit metadata'. It distinguishes from siblings like reddit_subreddit_posts by noting it returns both metadata and sample posts, and explicitly lists omitted fields (subscriber counts, icons, banners) due to anonymous access.

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 implies usage for getting subreddit metadata and sample posts, but does not explicitly name sibling tools or state when not to use it. The context from sibling list suggests it is for overview vs. detailed posts/comments, but the description itself lacks direct comparison.

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