Activate volume

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

No annotations are provided, so the description must disclose behavioral traits itself. It only says 'Activate' without explaining side effects, whether the DR volume becomes read-write, whether replication to the standby is stopped, whether the operation is reversible, or what prerequisites must exist. This is a mutating state change, so the lack of behavioral detail 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 concise and front-loaded, with a useful documentation link appended. It earns credit for being easy to scan, though its brevity contributes to the lack of semantic coverage in other dimensions.

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 state-changing operation with no annotations, no output schema, and two undocumented parameters, the inline description is too sparse to fully support correct invocation. The docs link is a helpful reference, but the description alone does not convey prerequisites, parameter meanings, or behavioral consequences.

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%, so the description must compensate for the bare schema, which only lists 'name' and 'frontend' as strings. The description does not explain that 'name' identifies the standby volume or what values 'frontend' accepts, leaving the agent without enough information to invoke the tool correctly.

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 states a specific action ('Activate') on a specific resource ('standby (DR) volume'), which is more precise than the title and suggests a distinct operation from ordinary volume attach. However, it does not explicitly differentiate itself from sibling tools like volume_attach or clarify the failover context beyond the DR term.

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 explicit guidance on when to use this tool versus alternatives such as volume_attach or volume_detach. The phrase 'standby (DR) volume' implies the intended scenario, and the Longhorn docs link may help, but the description itself provides no prerequisites, conditions, or exclusions.

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