Create Web Page

Add Content Block

block.add

Append a new content block to a link-in-bio page. The block must match one of the 13 allowed types (link, social_row, whatsapp, phone_call, email_contact, image, gallery, video_embed, text, map_embed, product_card, lead_form, reviews) with that type's strict props. The server generates the block id and returns it in the response. For already-published pages, this saves an unpublished latest revision only. Do not call page.publish in the same assistant turn after this edit. Stop and tell the user the draft/preview was updated, then wait for a separate user message that explicitly asks to update the live link, publish, or make the changes public before calling page.publish. Do NOT call page.unpublish either — the live page should stay public; only unpublish when the user explicitly asks to take it down. The response includes nextSteps: after adding a block, share these hints with the user so they know what else would make the page more complete.

A4.9/5.0

Behavior5/5

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

Beyond the annotations (which provide no safety hints), the description discloses key behaviors: server generates the block id, the operation saves an unpublished revision for published pages, and the response includes nextSteps. It also instructs the agent to share those nextSteps hints with the user. These details add substantial context about side effects and follow-up actions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Although long, every sentence adds essential information: core action, constraints, server behavior, draft semantics, publish/unpublish workflow warnings, and response handling. The structure is logical and front-loaded, with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (13 block types, nested schema, multiple sibling tools for publishing/unpublishing), the description is remarkably complete. It covers what happens to published pages, how to handle publishing, and what to do with the response (share nextSteps), making it self-sufficient for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 33% (only 'block' has a top-level description), so the description must compensate. It does so by listing all 13 allowed types and stressing that strict props must be used, plus noting that the server generates the block id. However, it does not explain the individual type-specific props beyond echoing the schema, which still does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource: 'Append a new content block to a link-in-bio page.' It further enumerates the 13 allowed block types, making the tool's scope unmistakable and clearly distinguishing it from siblings like block.update and block.delete.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit workflow guidance: for published pages it creates an unpublished revision, and it explicitly warns against calling page.publish or page.unpublish in the same turn unless the user explicitly requests it. This gives clear when-to-use and when-not-to-use context, including alternatives (publish/unpublish).

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

A4.1/5.0

Disambiguation4/5

Most tools target distinct resources and actions (blocks, accounts, pages), but page.create and page.create_from_brief both create pages, and page.intake.start vs page.onboarding.start/update are overlapping planning helpers. The detailed descriptions help disambiguate, though an agent might still pause on choosing between them.

Naming Consistency5/5

All tool names follow a consistent lowercase dot-separated resource.action pattern (e.g., block.add, page.publish, account.whoami). Nested resources like page.header.update and page.onboarding.update extend the same rule without mixing conventions.

Tool Count3/5

At 23 tools, the count sits in the borderline 16-25 range. Many tools are specific and justified, but the planning helpers (intake/onboarding) and multiple page creation variants add bulk that could be consolidated.

Completeness3/5

The server covers create, read, update, block management, and publish/unpublish, but misses a page.delete operation, leaving a lifecycle dead-end. Account tools are also minimal, limited to reading/listing without management capabilities.
