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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the output fields (title + author) but says nothing about network requests, authentication, rate limits, or error behavior. Minimal transparency beyond the immediate purpose.

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 sentence with no filler. It front-loads the main purpose ('DeviantArt Meta') and conveys the essential output in a compact form.

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?

Despite having an output schema and a simple signature, the missing parameter semantics and lack of annotations make the description incomplete for correct invocation. No guidance on input format or expected URL patterns leaves a critical hole in an otherwise simple tool.

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 has a single parameter 'q' with zero description coverage, and the tool description does not explain what 'q' represents. An agent cannot determine whether to pass a URL, an ID, or something else. This is a critical gap for a tool with only one input.

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 resource (DeviantArt deviation) and what is returned (title + author) via oEmbed. It implicitly distinguishes from sibling tools like devto or medium by naming DeviantArt, but the verb is implied ('Meta') rather than explicit.

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 other oEmbed-type siblings (e.g., vimeo, youtube). It doesn't state the required input format (URL vs. ID) or any conditions for use, leaving the agent to infer.

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