reddit_search

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

No annotations are provided, and the description only says 'Search Reddit posts.' It does not disclose authentication requirements (access_token), rate limits, returned data format, or pagination behavior. The agent has no insight into side effects or constraints.

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?

At three words, the description is very concise but lacks critical information for a search tool with five parameters. It is front-loaded with the core purpose but does not earn its brevity as it fails to convey usage details.

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 (five parameters, no output schema, no annotations), the description is grossly incomplete. It provides no context for parameter values, expected behavior, or return structure, leaving the agent ill-equipped to use it correctly.

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?

The description adds no meaning to the input schema parameters. With 0% schema description coverage, the agent learns nothing about 'q', 'subreddit', 'sort', or 'limit' beyond their names and types.

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 states 'Search Reddit posts.' which clearly identifies the action (search) and resource (Reddit posts). It distinguishes from sibling tools like reddit_comment, reddit_post, etc., which have different purposes. However, it lacks any additional context that would make it excellent, such as mentioning optional filters.

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 versus alternatives (e.g., reddit_read or reddit_post). With many Reddit and search siblings, the agent has no basis to choose this tool.

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