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

Annotations already declare this as a safe, idempotent, non-destructive read operation, so the safety profile is covered. The description adds useful selection semantics ('newest booking') and offer scoping, but it does not explain what 'progress' includes, what happens when no booking exists, or any authorization context.

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 a single efficient sentence with the scope and filtering behavior front-loaded and no wasted clauses.

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?

The tool is simple and annotations cover its safety profile, but with no output schema the description should clarify what 'progress' returns or what empty results look like. As written, an agent can infer basic selection behavior but not the response shape or failure modes.

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?

With 0% schema description coverage, the optional offerId parameter is documented only by the schema type and name. The description partially compensates by explaining that offerId scopes the result to the newest booking for an offer and that no offerId means the newest booking of all, but it gives no format or validation 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 identifies the specific resource (booking progress), the selection scope (newest booking), and the optional offer filter. However, it does not explicitly distinguish this tool from the sibling get_booking_status or find_my_booking, leaving some ambiguity about when this progress view differs from a status lookup.

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?

The description implies that providing an offer targets the newest booking for that offer and omitting it targets the newest booking overall, but it gives no explicit when-to-use guidance and names no alternatives among the many booking-related sibling tools.

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