set_default_ui_page

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

The description reveals that the tool implements a page reorder (not an explicit default property) and defaults to dry_run=True. However, with no annotations, it omits details on side effects, authorization, or reversibility.

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 concise, with two sentences that front-load the core functionality. No unnecessary words or repetition.

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?

The description is incomplete for a 5-parameter tool with no schema descriptions. It lacks explanations for host and scope_id, and provides no guidance on output or errors. The output schema partially compensates for return values, but parameter gaps remain.

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?

With 0% schema coverage, the description should explain all parameters. It clarifies scope, page_id, and dry_run but does not define host or scope_id, leaving a significant 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 clearly states the tool's purpose: to make a page the default/first page of an activity or remote UI. It also explains the mechanism (page reorder) and distinguishes it from siblings like update_ui_page or delete_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?

The description implies this is the correct tool for setting a default page, but does not explicitly state when to use it over alternatives. It mentions dry_run default but lacks guidance on prerequisites or exclusions.

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