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

With no annotations, the description carries the full burden for behavioral disclosure. It only says 'OCR table from image URL' and does not mention return format, failure modes, supported image formats, or side effects, which is insufficient for a tool with no structured annotations.

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 five-word sentence, front-loaded with the action and subject. There is zero redundant information, making it highly efficient.

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?

While the tool is simple (one parameter, no output schema), the description does not compensate for the absence of annotations or explain expected outputs or use cases. Given the large number of sibling tools with overlapping functionality, this description is not sufficient for confident selection.

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 one parameter 'url' with no description and 0% coverage. The description adds that this is an 'image URL', providing minimal but useful semantic context beyond the raw schema. It does not clarify format, size limits, or other constraints.

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 action (OCR) and the resource (table from an image URL), which is specific enough to convey the core purpose. However, it does not distinguish itself from close sibling tools like ocr_image, ocr_url, or ocr_table_url, so it doesn't fully separate from alternatives.

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 provided about when to use this tool versus the many sibling OCR and table extraction tools. The description only says what it does, leaving the agent to infer the appropriate context without exclusions or alternatives.

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