search_reddit

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

With no annotations, the description fully carries behavioral transparency: it discloses RSS usage, no API key needed, return fields, max 25 results, and missing features (comment trees, scores). No mention of rate limits or auth, but adequate for a public RSS feed tool.

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, front-loaded with the core action, each sentence adds distinct information. No redundancy or filler.

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 no output schema, the description explicitly lists return fields and notes the max results and RSS limitations. It misses error handling or pagination details, but is reasonably complete for a simple search tool.

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 descriptions cover 4 of 5 parameters (80%). The description adds context for subreddit and limit (max 25), but does not elaborate on query, sort, or time beyond what the schema provides. Adequate but minimal added value.

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 the tool searches Reddit posts via RSS, specifies what it returns (title, author, link, etc.), and implicitly distinguishes from siblings by noting RSS limitations and no comment trees/scores.

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 mentions optional subreddit restriction and RSS limitations, but does not explicitly compare with 'browse_subreddit' or 'get_post_comments' or provide when-not-to-use guidance.

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