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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful context beyond that: it shows settings 'as callers hear it', notes business hours are read-only, and mentions listing the last few published versions for restore.

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 main purpose and then enumerates the returned fields in a single long sentence, followed by two short sentences for usage. It is informative but somewhat run-on; the enumeration could be tightened, though every item is relevant to the receptionist setup.

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?

Given the tool is a read-only, zero-parameter operation with an output schema, the description provides everything needed: what it returns, why to call it (before update_ai_setup), and its relation to restore_ai_setup_version. No critical behavioral or usage information is 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 there are no parameter semantics to document. The baseline for zero-parameter tools is 4, and the description correctly does not fabricate parameter details.

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 ('Shows how... is set up right now') and resource ('AI receptionist'), and explicitly distinguishes itself from update_ai_setup and restore_ai_setup_version. An agent can tell exactly what this tool returns without opening the schema.

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 context: call before update_ai_setup to base changes on current wording, and use it to get the version list needed by restore_ai_setup_version. It does not explicitly state when not to use it, but the alternatives are named and the primary use case is well-defined.

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