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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description is consistent with that: 'opens nothing by itself' and 'Returns how to do it... step by step' make the non-mutating behavior explicit. It adds useful operational context beyond the annotations, including the note that AppFlowy Cloud has a REST API but no hosted MCP server. It does not describe response format or size, which is the remaining gap.

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 core clarification ('opens nothing by itself; then do it with the cotlet_browser_* tools') is buried mid-sentence after a misleading opening clause. The trailing API-availability note reads as meta-commentary and does not help an agent invoke the tool. It is not bloated, but the front-loading works against the reader.

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?

There are no parameters and no output schema, so the description carries the burden of explaining what comes back. It partially does ('step by step (screens, buttons, fields)'), but leaves unclear whether the response is free text, which browser tool to start with, or whether a workspace/page identifier is needed to act on the guide. Adequate but with noticeable gaps for a zero-parameter routing tool.

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?

The tool takes zero parameters, so the baseline is 4 under the rubric. There is nothing in the schema for the description to compensate for, and the description correctly signals that the call requires no input.

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 does state a specific verb and resource: it returns a step-by-step guide for creating an AppFlowy database row, and explicitly says it 'opens nothing by itself.' That is a clear, non-tautological purpose, and it names the downstream cotlet_browser_* tools. It loses a point because the leading sentence, 'Create database row in the user's own AppFlowy account,' frames the tool as the creator, which is the opposite of what the body says, and it never distinguishes itself from the appflowy_create_page sibling.

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?

There is implied workflow guidance: call this to get instructions, 'then do it with the cotlet_browser_* tools in the user's AppFlowy Cloud Browser.' That tells the agent the sequencing but not the conditions for choosing this over a sibling like appflowy_create_page or going straight to the browser tools. No when-not-to-use guidance is given.

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