page_duplicate

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

With no annotations, the description carries the full behavioral burden and discloses almost nothing: it doesn't say where the duplicate is inserted (after the original?), whether the original is modified, whether the operation is undoable, or how the required index is interpreted.

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 wasted words. It is efficient, though its brevity edges into under-specification rather than pure conciseness.

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?

For a mutation tool with no annotations, no output schema, and an undocumented required parameter, the description is far too thin. An agent cannot confidently predict the result of the call or the meaning of the scope phrase 'active document'.

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 coverage is 50%; the required 'index' parameter has no description at all, and the description does not compensate by explaining whether index is the source page's index or an insertion position. Claims 'the active document' while the schema also accepts a document_id, adding ambiguity rather than clarity.

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?

States a specific verb (duplicate) and resource (page) scoped to a document. It is distinguishable from page_add, page_delete, and page_move, though it never acknowledges the sibling duplicators (master_duplicate, style_duplicate) or clarifies how duplication differs from page_add.

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 when-to-use guidance, no prerequisites, and no statement of how this differs from page_add for creating a page. An agent gets no help deciding between duplication and adding a blank page.

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