transfer_away_reject

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions the required reason length (redundant with schema) but does not disclose the effects of rejection, whether the action is reversible, or any side effects on the transfer process. For a mutation tool, this is a significant gap.

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, focused sentence that immediately states the tool's purpose, with the reason constraint added in a dependent clause. Every word earns its place, making it highly concise and front-loaded.

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?

For a simple two-parameter mutation tool with no output schema, the description covers the basic purpose and required input. However, it omits important context such as whether the transfer must be in a pending state and what the success/failure response looks like. The tool is functional but leaves some gaps in operational completeness.

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 100%, so the baseline is 3. The description adds no new meaning beyond restating the reason constraint that is already fully specified in the schema. The domain parameter is also already described clearly in the schema, so the description provides no additional semantic value.

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 uses a specific verb 'Reject' and clearly identifies the resource as 'outgoing domain transfer (transfer away from your account to another registrar)', which distinguishes it from sibling tools like transfer_away_approve. The parenthetical clarification further pinpoints the exact scenario.

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 the usage context (rejecting an outgoing transfer) but does not explicitly state when to use this tool versus transfer_away_approve or transfer_cancel, nor does it mention any prerequisites like requiring a pending transfer. The context is inferable but not explicit.

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