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

Annotations declare readOnlyHint=true and destructiveHint=false; the description reinforces this with 'opens nothing by itself', which preempts the misreading that 'close and reopen tickets' is a mutation. It also discloses the return content (screens, buttons, fields) and the absence of an official MCP server. Return shape and pagination-level detail are not expanded, keeping it at 4.

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 purpose and the no-side-effects warning are front-loaded, which is good. However, 'from ChatGPT, Claude or any AI agent' is filler, and the trailing note about Skiddle's public beta API and the 31 Oct 2026 MCP check is tangential to invoking this tool and dilutes the operative instructions.

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?

With no parameters and no output schema, the description carries the necessary burden and does so: it says what is returned, that nothing is executed, and which tool family completes the task. Minor incompleteness around what happens if the user is not signed in to Skiddle, but the definition is otherwise sufficient to call 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?

The tool takes zero parameters and the schema is closed (additionalProperties: false), so there is nothing for the description to disambiguate. Baseline of 4 applies; no parameter-related gaps exist.

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 states a concrete action and resource ('Close and reopen tickets in the user's own Skiddle account') and immediately clarifies the tool's real nature: it returns step-by-step guidance rather than performing the action. It stops short of differentiating itself from the other skiddle_* siblings such as skiddle_read_ticket_sales, but the guidance-vs-execution split is unambiguous.

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 gives explicit workflow ordering: read the returned steps, then execute them with cotlet_browser_* tools in the Skiddle Cloud Browser. That names the alternative mechanism and the condition for using it. What is missing is any when-not-to-use guidance (for example, when the official API or another skiddle_* tool would suffice).

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