reddit_subscribe

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

No annotations provided; the description simply restates the action without detailing behavioral traits like authentication requirements, rate limits, or side effects (state change). Insufficient for a write operation.

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?

Extremely concise: one sentence with no wasted words. Front-loaded and efficiently communicates the core purpose.

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?

No output schema and no annotations; description lacks information about return values, success/failure indicators, or the effect on user's subscriptions. Incomplete for a tool with no 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?

Schema coverage is only 33% (action param described). Description does not clarify 'access_token' or 'sr' (subreddit name) beyond the parameter names. No added value over schema.

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?

Description clearly states the tool subscribes or unsubscribes to a Reddit subreddit, using a specific verb and resource, and is distinct from sibling tools like reddit_comment, reddit_post, etc.

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?

No guidance on when to use this tool versus alternatives (e.g., browsing or posting). No when-not or exclusions provided.

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