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

The description is consistent with annotations and explains the surprising part: despite the 'create' name, readOnlyHint=true is correct because the tool 'opens nothing by itself' and only returns instructions. It also discloses that Arborgold publishes no API, webhooks, or Zapier app, which preempts an agent's assumption that an API path exists. It stops short of describing the shape/length of the returned steps or any auth or account prerequisites.

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 instruction is front-loaded and clear, but the trailing API aside ('connects to QuickBooks, Google, Twilio and SiteOne (checked 9 Nov 2026)') is padding that does not help an agent select or invoke the tool, and the date is oddly future-dated. The result is two useful sentences buried with vendor trivia.

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, guidance-only tool with no output schema, the description covers what it returns (step-by-step screens/buttons/fields) and how to continue (browser tools). Missing are prerequisites such as whether an Arborgold Cloud Browser session or login must already exist, which matters before the follow-up tool calls.

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 input schema has zero parameters, so there is no parameter semantics to add and the baseline is 4. The description is consistent with an empty schema, though it never states that the estimate details must be supplied later through the browser tools rather than here.

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 concrete verb and resource and, crucially, clarifies the real behavior: it 'Returns how to do it in Arborgold step by step (screens, buttons, fields) and opens nothing by itself.' The opening clause 'Create estimate in the user's own Arborgold account' is goal-shaped rather than function-shaped and briefly reads like a write action, but the follow-up sentence resolves it and distinguishes this tool from the cotlet_browser_* action tools.

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 sequencing: call this first to get steps, 'then do it with the cotlet_browser_* tools in the user's Arborgold Cloud Browser.' That is a real hand-off to named siblings. It lacks an explicit when-not clause (e.g., if the API existed, or if the user wants a listing rather than a creation), but the intended workflow is unambiguous.

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