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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false; the description reinforces this with 'opens nothing by itself,' which is exactly the fact an agent needs to avoid assuming a side effect occurred. It also discloses the operational constraint that mHelpDesk has no public API, webhooks or Zapier app, justifying why browser automation is the execution path. It does not describe the shape or length of the returned instructions.

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 critical facts are front-loaded: what it returns, that it performs nothing, and which tools execute the task. The final sentence about the absent public API and QuickBooks/Google Calendar syncs is somewhat tangential but earns its place by explaining why the browser-tool handoff is mandatory. The parenthetical 'checked 9 Nov 2026' adds noise.

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?

For a zero-parameter, no-output-schema guidance tool, the description covers what it returns, what it does not do, and how to proceed afterwards. The remaining gap is the return format — whether the instructions arrive as numbered steps, include field values, or vary by job type — which an agent would benefit from knowing.

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?

There are zero parameters and 100% schema coverage, so the baseline is 4. The description does not explain how the job details (customer, date, service) are conveyed, but with no input schema there is nothing for it to document.

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 names a specific verb and resource (schedule a job in the user's mHelpDesk account) and immediately clarifies the real output: step-by-step instructions, not an action. That correction is essential because the tool name implies it performs the scheduling, so an agent that reads only the name would be misled. It is clear, but the opening sentence briefly reinforces the misleading action framing before the correction lands.

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 two-phase guidance: call this to learn the screens/buttons/fields, then execute with the cotlet_browser_* tools in the user's Cloud Browser. That is a concrete when-to-use and what-to-use-next instruction. It stops short of stating when NOT to call it (e.g. when the user just wants the job data or an unrelated mHelpDesk operation).

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