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

With no annotations, the description carries the full burden. It indicates the tool provides 'real-time' sentiment analysis but does not elaborate on behavior such as data source reliability, update frequency, or potential limitations. The transparency is minimal but not misleading.

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 concise, consisting of a one-line purpose statement followed by a brief structured list of arguments. Every sentence adds value with no wasted words. The most important information is front-loaded.

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 has 3 parameters and no output schema, the description adequately explains inputs but fails to describe the return format or what 'sentiment analysis' precisely yields. It is adequate for basic use but lacks completeness for complex decision-making.

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 schema provides only types and defaults, with 0% coverage. The description adds significant meaning by explaining each parameter: symbol with examples, category with explicit options, and limit as the number of posts. This compensates fully for the schema's lack of detail.

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 'Real-time Reddit sentiment analysis for stocks and crypto' using a specific verb and resource. It distinguishes this tool from siblings as no other sibling provides Reddit sentiment analysis, making its purpose unique and well-defined.

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 implies usage for sentiment analysis but does not provide explicit guidelines on when to use this tool versus alternatives, nor does it mention conditions where it should not be used. Some context is given by the parameter explanations, but no direct usage guidance.

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