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

The description adds useful details beyond the read-only annotations: it lists the account fields returned and notes that billing is replaced by the SkipCalls dashboard link in ChatGPT. It does not describe auth requirements or rate limits, but it provides solid context for a read-only lookup tool.

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 description is front-loaded with the core purpose and then usage guidance. It is dense but every clause contributes relevant detail about the returned account fields, though the single long enumeration makes it slightly run-on.

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 carries the burden of explaining what is returned, and it does so thoroughly: business name, workspace ID, timezone, user vs owner, team size, receptionists, phone numbers, plan, and minute balance. That is complete enough for an agent to know what to expect.

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 no parameters, so the baseline is 4. The description does not need to explain parameter behavior, and it correctly focuses on the returned account information instead.

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 a specific verb and resource ('Identify the connected SkipCalls account') and enumerates exactly what account details are returned. It is highly distinguishable from most siblings by its account-identity scope, though it does not explicitly name alternatives like getBillingInfo or getOverview.

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 clear usage context: 'Call when the user asks which account this is or before account-wide work.' It does not, however, state when not to use it or route to sibling tools such as getBillingInfo for billing-specific questions.

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