add_user_seat_offering

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

Annotations indicate readOnlyHint=false and destructiveHint=false, which the description supports by stating 'creates data'. The description mentions the option to assign a seat via the body parameter, but does not disclose behavior on duplicate entries, error handling, or side effects. Some behavioral context is added beyond annotations.

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 concise (two sentences plus a header with HTTP method and endpoint) and front-loaded with key information. The header is informative but not strictly necessary; overall, no wasted text.

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 has 3 parameters and no output schema, but the description omits several critical details: what the response is (e.g., success message or created object), whether the user must exist, what happens if the user is already part of the offering, and any side effects. Given these gaps, the description is incomplete for reliable invocation.

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?

Input schema has 100% coverage; description adds value by explaining the purpose of the optional body parameter add_to_active_seat (assign a seat). For id and uid, it restates schema info but does not add new semantics, though the body parameter explanation justifies a score above baseline of 3.

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 'Add a user to a seat offering' and includes the HTTP POST endpoint, specifying the verb and resource. It distinguishes from sibling tools like create_seat_offering (which creates the offering) and remove_user_seat (which removes a user).

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 usage for adding a user to an existing seat offering, but does not explicitly state when to use this tool versus alternatives (e.g., create_seat_offering, remove_user_seat). No prerequisites or context about when it is appropriate are provided.

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