Reddit Resolve Subreddits

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

With no annotations provided, the description must fully disclose behavior. It mentions multiple data sources (search, cache, hints) and caching via SQLite, but does not detail output format, side effects, authentication needs, or rate limits. The description is moderately transparent but lacks important operational details.

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 a single, concise sentence that efficiently communicates the tool's purpose and methodology. It avoids unnecessary words, though the use of technical terms like 'SQLite cache' and 'priority hints' could be slightly confusing without further context.

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 three parameters and no output schema, the description does not specify the return format (e.g., list of strings, objects with scores). It adequately covers the input and method but leaves the agent to infer what the response looks like, which is a notable gap for a tool with no explicit output schema.

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?

All three parameters have schema descriptions (100% coverage), so the baseline is 3. The overall description adds context about ranking and ranking methods but does not provide additional semantic detail for individual parameters beyond what the schema already offers.

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 resolves a topic into ranked subreddit candidates, which is a specific verb+resource combination. It distinguishes itself from sibling tools like reddit_search (general search) and reddit_subreddits (likely listing subreddits) by focusing on resolving a topic into a ranked list of candidates.

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 explicit guidance on when to use this tool versus siblings like reddit_search or reddit_subreddits. It does not state prerequisites, exclusions, or scenarios where another tool would be more appropriate. The usage context is only implied by the tool's purpose.

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