unit_unmask_tool

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

No annotations provided, so the description carries the full burden. It only states the operation type without disclosing the effect (e.g., whether it requires root privileges, whether it changes system state permanently, or what happens if the unit is not currently masked). No mention of side effects or prerequisites.

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, efficient sentence without fluff. However, the description is so brief that it borders on under-specification; it could be expanded to include behavioral context while still being concise.

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?

Given that this tool performs a system mutation (unmasking a unit), the description should cover prerequisites, error conditions, and the effect on the system. It is a state-changing operation with potential security implications, and without annotations or explanation, the description is incomplete.

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 parameter is already documented as 'Systemd unit name'. The description adds no additional semantic detail beyond the operation itself, and since there is only one required parameter with full coverage, the baseline 3 is 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?

The description clearly states a specific verb ('Unmask') and resource ('a previously masked unit'), making it obvious this tool reverses the action of unit_mask_tool. It is distinct from siblings like unit_enable_tool and unit_start_tool.

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?

No explicit guidance on when to use this tool versus alternatives, such as when a unit is masked and needs to be re-enabled for use. Context is very thin, relying on the description to imply it's the counterpart to masking, but no exclusions or alternatives are mentioned.

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