Behavior3/5

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It describes the tool as a simple get operation and mentions a dependency (connected account). However, it does not detail return format, pagination, or potential side effects. The description is adequate but lacks depth.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is incredibly concise, consisting of just two sentences with no extraneous information. Every word contributes to the understanding of the tool's purpose and usage.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's low complexity (one parameter, no output schema), the description is mostly complete. It explains the purpose and prerequisite. However, it could briefly mention what is returned (e.g., list of subreddit names/IDs) to fully inform the agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with a clear description for 'accountId'. The tool description does not add additional meaning beyond the schema, so it scores the baseline of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and resource 'subreddits' with a qualifier 'available for a connected Reddit account'. It also adds context 'needed for posting to subreddits', which further clarifies the purpose and distinguishes it from sibling tools like 'zernio_reddit_submit_post' or 'zernio_search_reddit'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'needed for posting to subreddits' implies this tool should be used as a prerequisite before posting, but it does not explicitly state when not to use it or mention alternatives like 'zernio_set_default_reddit_subreddit'. However, the implied usage is clear enough.

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