execute_rollback

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

With no annotations, the description carries the full burden of behavioral disclosure. It mentions token rejection but omits critical details such as what the rollback actually changes, whether it is destructive, what permissions are required, and what happens on success. For a mutation tool, this is insufficient.

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 two short sentences with no filler. 'Execute an approved rollback' front-loads the core purpose, and 'Rejects missing/invalid tokens' adds a key behavioral constraint. Every word earns its place.

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 high-stakes rollback tool, the description is critically underspecified. It lacks guidance on when to use it relative to alternatives, side effects, prerequisites beyond the token, and error behavior. The existence of an output schema does not compensate for the absence of usage context and behavioral disclosure.

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%, and the description adds no parameter-specific explanations. While the parameter names (model_name, target_version, approval_token) are somewhat self-explanatory, the description does not clarify their roles or constraints beyond what the schema already shows.

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 the tool's function: 'Execute an approved rollback.' The verb 'execute' is specific and distinguishes this from the sibling 'propose_rollback.' It also mentions token validation, adding a behavioral detail that clarifies the tool's scope.

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 phrase 'approved rollback' implies the tool should only be used after approval, and 'Rejects missing/invalid tokens' indicates that a valid approval token is a prerequisite. This provides clear contextual guidance without explicitly naming alternatives, but the sibling name 'propose_rollback' strongly implies the distinction.

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