apex_add_page

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

The annotations (readOnlyHint=false) already indicate this is a write operation, but the description adds little beyond that: it only restates 'Add a new page' with no details on side effects, required permissions, or impact on the app. The 'page_mode' mention is unhelpful and potentially misleading.

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 very short and front-loaded with the action, which is good for conciseness. However, the 'page_mode: Normal or Modal Dialog' phrase is unnecessary and somewhat off-target, making the sentence less effective than a wholly accurate one-liner would be.

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?

Given the tool has six parameters, an output schema, and numerous sibling operations, this description is far too sparse. It does not explain how adding a page fits into the broader app-building workflow, nor does it highlight key options or constraints, leaving the agent under-informed for a complex write operation.

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 100%, so the baseline is 3, but the description introduces 'page_mode' which is not a schema parameter (the actual parameter is 'page_type'). This actively confuses rather than adds meaning, so I rate it below the baseline.

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 tool's action ('Add a new page') and resource ('the app'), distinguishing it from sibling tools like apex_update_page and apex_delete_page. However, the mention of 'page_mode' is confusing because the schema uses 'page_type', which slightly detracts from clarity.

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?

The description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. With many sibling tools for adding regions, items, or processes, such guidance is essential but entirely absent.

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