page_ink

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

No annotations are provided, so the description carries the full burden. It implies a read-only statistics operation but never confirms that, nor does it say whether the page must exist, what happens for blank pages, or whether path refers to a notebook or page file. Only the returned fields are hinted at.

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?

A single front-loaded sentence with no filler; the metric list is efficient. The telegraphic phrasing is compact but borders on under-specification rather than waste.

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?

An output schema exists, so return values needn't be explained, but with zero annotation coverage and two completely undocumented parameters the description leaves too much for the agent to guess. For a statistics tool that takes a path and page index, the minimum context on inputs is missing.

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 description coverage is 0% and the description does not document either parameter. 'of a page' vaguely gestures at the page parameter but gives no numbering base or default, and the required path parameter is not explained at all (notebook path? page file path?). The description fails to compensate for the coverage gap.

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 names a specific resource (a page) and enumerates exactly what it reports: stroke count, colours, pen widths, written area. That distinguishes it reasonably well from render_page and page_layout, though it never explicitly contrasts with the closely related page_marks. Clear purpose, weak sibling differentiation.

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?

There is no when-to-use guidance at all — no statement of what question this answers that page_marks or page_layout would not, and no exclusions. The agent must infer usage entirely from the tool name and sibling list.

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