add_user_seat_offering

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

The description goes well beyond the annotations by explaining that the operation creates a record or triggers an action, is not idempotent, has server-side auth, is throttled, retries on 429/5xx, and surfaces non-2xx responses as tool errors. This gives the agent a rich behavioral model without contradicting any annotation.

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 structured into clear labeled sections: purpose, behavior, parameters, returns, and usage. It is longer than average but every section contributes necessary operational detail; there is no filler or repetition.

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 fully covers the return format, error status meanings, auth requirements, rate limits, idempotency, and pre-call checks. It is complete enough for an agent to invoke the tool correctly and understand what happens afterward.

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?

Although the schema already documents all parameters, the description adds crucial meaning: the entire JSON payload goes into the single `body` argument and is forwarded verbatim, and the `body` being optional in the spec does not mean the endpoint does not expect one. It also connects the optional seat-assignment behavior to the likely `add_to_active_seat` field.

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 clearly states a specific action: 'Add a user to the seat offering specified by the provided seat offering id.' It also mentions the optional seat-assignment behavior, distinguishing the operation from seat-offering creation, deletion, or removal. The HTTP verb and path add further precision.

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 'Use when' section is explicit: only use when the user asked to create this, and the description instructs checking with a read tool that the target exists and the record is not already there. It also lists related seat-offering tools, providing clear context for choosing among siblings.

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