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

No annotations are provided, so the description carries the full behavioral burden. It discloses no charge, pending-request semantics, owner confirmation/decline within 24 hours, and the important constraint about using the guest's real identity. This is far beyond what the title or schema conveys.

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?

Two sentences with no fluff. The core purpose is front-loaded, followed immediately by the behavioral caveats and usage requirement. Every sentence earns its place.

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 description covers the essential workflow: pending request, no charge, owner response timeline, and consent requirement. While the response format and optional parameter details are not explained, this is sufficient for a tool with a clear high-level operation and mostly optional schema fields.

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?

Schema description coverage is 0%, and the description only adds meaning to guest_name/guest_email and the dates/estimated total. It does not define or contextualize parameters like hot_tub, bed_linens, number_of_dogs, special_requests, or guest_phone, leaving most inputs underspecified for an agent.

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?

States a specific verb ('submit') and resource ('booking request for Lilla Älva'), and clearly distinguishes it from instant booking by explaining it creates a pending request. The description leaves no ambiguity about the tool's core function.

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?

Provides clear context: only submit after the guest has explicitly agreed to dates and estimated total, and use the guest's real name/email. It also communicates the non-instant nature and 24-hour owner response, but does not explicitly name sibling tools as alternatives.

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