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

With no annotations provided, the description must disclose behavioral traits but does not. It says nothing about whether the operation is read-only, what data is returned, how pagination works, or any side effects. This is a complete absence of behavioral information.

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 extremely short, but this is under-specification rather than conciseness. 'Subreddit Posts' contains no actionable information, so it fails to earn its place as a meaningful description.

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?

This tool has 5 parameters, no output schema, no annotations, and many sibling tools. The description is a bare fragment that explains nothing about return values, usage context, or how it relates to similar tools. It is completely inadequate for an agent to select and invoke 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 parameter semantics, but the input schema covers all 5 parameters with descriptions (100% coverage). However, these descriptions are generic (e.g., 'Sort order' and 'Timeframe filter') and lack allowed values or detailed meaning. Per the baseline rule, with high schema coverage, a score of 3 is appropriate, though the schema's shallow descriptions limit its practical value.

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 'Subreddit Posts' is a noun phrase that essentially restates the tool name. It does not specify an action (like scrape, list, or search) and fails to distinguish this tool from siblings such as scrapecreators_subreddit_search or scrapecreators_reddit.

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 is given on when to use this tool versus alternative scrapecreators tools. The description provides no context, prerequisites, or exclusions, leaving the agent to guess based on the name alone.

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