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

The key behavioral fact – 'opens nothing by itself' – is disclosed and is consistent with readOnlyHint=true, so an agent will not expect the closure to actually take effect. It also explains the handoff to the browser tools and notes there is no owner-facing official API, which is useful context beyond the annotations. It does not say whether the account must already be connected or whether a browser session must be open before use.

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 workflow constraint is front-loaded, which is good, but 'from ChatGPT, Claude or any AI agent' is padding that adds no decision-relevant information. The trailing note about ChowNow's API and the 'checked 28 Oct 2026' date are tangential to invoking the tool and lengthen it without improving selection.

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 output schema, the description usefully describes what comes back (step-by-step screens, buttons, fields) and how to act on it. For a zero-parameter guide tool this is close to complete; the remaining gap is any prerequisite about account connection or browser session state.

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 beyond the input schema. Baseline of 4 applies.

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 concretely that the tool returns step-by-step instructions (screens, buttons, fields) for setting a temporary closure in ChowNow, which is more specific than the name alone. The name and title ('Set temporary closure') imply a mutation, so the description has to work to clarify it is really a guide tool – it does that, but the tension is only resolved partway through the text.

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 an explicit workflow: call this first to get the steps, then carry them out using the cotlet_browser_* tools in the user's ChowNow Cloud Browser. That sequencing is genuinely actionable. It stops short of any exclusion ('do not use for X') and never distinguishes this from sibling tools such as chownow_update_hours.

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