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

No annotations exist, so the description carries full responsibility. It states the tool returns posts with subreddit, score, and permalink but omits behavioral traits like read-only nature, rate limits, or authentication needs. It is adequate but not comprehensive.

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 two sentences with no redundancy. It front-loads the core function in the first sentence and adds use case and output in the second, making it efficient and scannable.

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 lists return fields (subreddit, score, permalink), which is useful. It covers basic purpose but lacks details on pagination, error handling, or output structure. It is fairly 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 coverage is 33% (only 'query' described). The description adds minimal meaning: it implies 'query' is the search term but does not explain 'limit' or 'since_days' beyond their defaults. The description provides no additional context for these parameters.

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 'Site-wide search across Reddit', specifying the verb (search) and resource (Reddit). It also differentiates from siblings by naming the platform and mentioning use cases like community sentiment and niche subreddits.

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 guidance on when to use ('Best for community sentiment, niche subreddit signal'), which implies context. However, it does not explicitly state when not to use or name alternative tools, but sibling names are available.

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