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

Since all annotations are false, the description carries the full burden and shoulders it well. It discloses the empty placeholder state, the need to fill via block_update, the absence of a publish action in the response, and the expiration of anonymous demo pages.

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?

Four dense sentences, with purpose first, then input guidance, then behavioral guardrails. Every sentence contributes operational value and there is no filler or repetition of schema boilerplate.

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 an output schema exists, return values do not need describing; the description covers the create workflow, the no-publish constraint, and post-call behavior. It is slightly less than complete because the schema leaves initialPrompt undocumented and the description does not clarify it, but an agent can still call the tool correctly.

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 high (89%), so the schema already documents most parameters. The description adds useful semantics by explaining that preset can be 'auto' inferred from businessType/style and by naming title, displayName, and preset as key inputs. One minor issue: 'Provide title, displayName, and a preset' overstates displayName as required when it is optional in the schema.

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 opens with a specific verb+resource: 'Create a hosted link-in-bio page draft from a style preset.' It further separates itself from sibling tools by emphasizing it creates a draft only and does not return a publish action, and by contrasting 'style preset' creation with brief-based creation.

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?

It tells the agent what inputs to provide, to not invent content, to stop after the tool and show the preview URL, and to avoid page_publish unless the user explicitly asks to publish. It even conditions the exception on exact user intent, which is unusually actionable.

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