update_pagebreak_position

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

The description adds no behavioral context beyond what annotations already provide. It does not mention side effects, preconditions (e.g., position must exist), what happens if the pagebreak field is omitted, or any return value. Annotations indicate readOnlyHint=false and destructiveHint=false, but the description itself is silent on behavior.

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, brief sentence with no wasted words. It is front-loaded but adds little beyond the tool name. It earns a decent score for conciseness, though it is somewhat under-specified.

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 without an output schema, this description is too sparse. It fails to explain what 'edit' changes, what response to expect, or any prerequisites. Given the complexity of the domain (pagebreak positions on documents), the description is not complete enough for an agent to use the tool confidently.

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 input schema already describes 3 of 4 parameters (75% coverage). The description itself provides no parameter information. Since schema coverage is reasonably high and the one undocumented parameter (pagebreak) is optional, the baseline score of 3 is appropriate.

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 'Edit a pagebreak position' uses a specific verb (Edit) and resource (pagebreak position), clearly indicating an update operation. This distinguishes it from sibling tools like create_pagebreak_position, delete_pagebreak_position, get_pagebreak_position, and list_pagebreak_positions.

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 guidance on when to use this tool versus alternatives. The verb 'Edit' implies modifying an existing pagebreak position, but this is only implicit and no exclusions or alternative tool references are provided.

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