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

The readOnlyHint=true annotation is consistent with the explicit statement that the tool 'opens nothing by itself', and the description adds real context beyond the annotation: the return value is a procedural walkthrough of screens, buttons and fields, and execution is handed off to browser tools. It does not state whether the user must be authenticated in Studio Manager or what happens if the account is not connected.

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 behavior and the browser hand-off are front-loaded effectively, but the final sentence is bloated: it repeats 'Eversports Studio Manager's official API' twice and enumerates all eight read-only areas, which adds little for tool selection. Trimming that to a single clause would sharpen it considerably.

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 burden of explaining the return value, and it does so ('step by step (screens, buttons, fields)'), plus the follow-up action. What remains thin is domain framing of what an 'article' is and any precondition on the user's Studio Manager account.

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 there is nothing for the description to disambiguate; baseline 4 applies. The description does not need to compensate for any schema gaps because the schema is empty and closed (additionalProperties: false).

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 gives a specific verb and resource and, crucially, clarifies that this tool does not perform the action: 'Returns how to do it in Eversports Studio Manager step by step ... and opens nothing by itself.' That distinguishes it from the cotlet_browser_* execution tools. The gap is that 'article' is never defined in Eversports terms (a product/catalog item?), leaving ambiguity against siblings like sell_a_product_from_the_sign_in or create_video_bundle.

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 clearly sequences usage: call this first to get the step-by-step procedure, then carry it out with the cotlet_browser_* tools in the Cloud Browser. It also explains why the official Provider API is not an option (read-only across eight areas), which is a useful exclusion. It stops short of naming specific sibling tools or stating prerequisites such as the account being connected.

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