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

The description resolves the apparent conflict between the mutating name and the readOnlyHint annotation by stating plainly that it 'opens nothing by itself' and only returns procedural text, which is the most important thing an agent needs to know here. It also names the output shape (screens, buttons, fields) and the browser dependency. It does not state whether the returned guide is cached or account-specific.

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 follow-up step are front-loaded, which is good, but the text carries fillers: 'from ChatGPT, Claude or any AI agent' and the dated API availability note ('checked 23 Oct 2026') do not help an agent decide or act. The middle clause about screens, buttons, and fields is useful but is tangled into the same sentence as the 'opens nothing' disclaimer.

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?

The description covers the unusual two-stage workflow well enough to call the tool, and there is no output schema that would need explaining. However, a tool whose name promises to set a status but which accepts no parameters and returns only generic instructions leaves the agent unclear about how the guide is tailored, if at all, to a particular content item. That ambiguity is the main thing missing.

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 per the baseline there is nothing for the schema to explain and nothing for the description to compensate for. The description correspondingly describes a parameterless lookup rather than implying hidden inputs, which is coherent. It earns no higher mark because it never explains why no target content is needed, which is the obvious question a caller will have.

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 first sentence names a specific operation and resource ('Set content status in Thought Industries') and immediately qualifies it: the tool returns instructions rather than performing the change. That distinguishes it from the mutating cotlet_browser_* siblings. It loses a point because the phrasing is dense and the 'returns how to do it' nature of the tool is buried inside a long sentence rather than stated as the primary behavior.

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?

The description gives explicit sequencing: call this first to get step-by-step instructions, then execute with the cotlet_browser_* tools in the Cloud Browser. It also explains why there is no alternative API path (no MCP server exists), which pre-empts a plausible wrong turn. It does not say when NOT to use it, e.g. that it should be skipped if the agent already knows the procedure.

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