set_transfer_protection

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

Annotations already declare readOnlyHint=false, destructiveHint=true and openWorldHint=true, so the agent knows this mutates external state. The description adds only the token '(deferred)', which is unexplained and ambiguous rather than clarifying what gets changed, when, or with what authorization.

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?

A single short, front-loaded sentence with no padding. However, the trailing '(deferred)' is cryptic and arguably does not earn its place since it is never explained.

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?

An output schema exists, so return values need not be described, and the schema covers both parameters. For a destructive mutation tool, though, the description lacks any permission, timing, or side-effect context, leaving it only minimally adequate.

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 both 'domain' (with format example) and 'enabled' (true=locks, false=allows) are already fully documented. The description adds no parameter meaning beyond the schema, making the baseline 3 appropriate.

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 (lock/unlock) and resource (domain transfer to another registrar), which an agent can distinguish from siblings like set_auto_renew or update_nameservers. It is clear what the tool does, though it never explicitly names a sibling or scope boundary.

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?

There is no when-to-use or when-not-to-use guidance, no prerequisites, and no alternatives mentioned. The agent must infer that this applies to domain transfer protection only from the name and the phrase 'transfer of a domain to another registrar'.

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