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

Annotations already declare this as a non-read-only, open-world, non-idempotent operation. The description adds useful context that it sends externally to the booking team, asks for missing details, and that a reply goes to the supplied email, though it does not discuss duplicate submissions or error behavior.

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?

Front-loads the action, then the precondition, required fields, missing-information instruction, and reply behavior. Every sentence adds useful information with no wasted wording.

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?

Covers the main submission workflow and confirmation requirement well, but for a 13-parameter tool with no schema descriptions and no output schema, several optional fields and validation details remain unexplained. It is adequate to invoke correctly in common cases but not fully complete.

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% across 13 parameters, so the description has to compensate. It usefully enumerates most core fields and clarifies one total budget amount in USD, but omits company, howHeard, additionalInfo, and alternativeDate, and gives no format guidance for dates or times.

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 and resource: sends a private-event inquiry to the Arcana booking team. The recipient and precondition make it distinguishable from related siblings such as prepare_inquiry.

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?

Gives an explicit precondition: use only after the person has seen the details and asked for it to be sent. It does not explicitly name prepare_inquiry as the preceding alternative, but the context is clear.

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