update_activity_ui_page

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

Description mentions it is a patch operation that replaces the items array, but does not discuss other parameters like name, grid_width, grid_height, or disclose potential side effects. No annotations are provided to supplement.

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 short but lacks structure (e.g., bullet points or parameter listing). It is under-informative rather than appropriately concise.

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?

Despite having an output schema, the description provides no information about behavior beyond replacing items. The tool has 6 parameters, and the description covers only one aspect, making it inadequate for effective use.

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 explain any parameter beyond items. Parameters like name, grid_width, grid_height are not described, leaving the agent with no semantic context.

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?

Tool name 'update_activity_ui_page' and description 'Patch a page; supplied items replace that page's items array' clearly indicate it updates a page by patching and replacing items. This distinguishes it from siblings like create_activity_ui_page and delete_activity_ui_page.

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 on when to use this tool versus alternatives such as 'update_profile_page' or 'reorder_activity_ui_pages'. The description lacks context about prerequisites or scenarios.

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