clokio_break_end

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

The annotations already indicate this is a mutating but non-destructive operation. The description adds no behavioral context beyond restating the state transition, such as whether an active break is required, what happens if none exists, or what the response indicates.

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, front-loaded sentence with no filler or redundant phrasing. It is efficient for what it conveys, but that efficiency comes at the cost of meaningful guidance.

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?

With no output schema, no parameter documentation, and no usage context, the description is too thin to support confident invocation. An agent is left to assume prerequisites, the meaning of pin, and the success/failure behavior on its own.

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 does not compensate for it. 'End a break for an employee' weakly implies that employee_code identifies the employee, but the optional pin parameter is completely unexplained, leaving its role ambiguous.

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 ('End') and identifies the resource ('a break for an employee'), so the core action is unambiguous. It clearly contrasts with the sibling clokio_break_start, though it does not explicitly name or differentiate itself from that sibling.

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 guidance on when to use this tool versus clokio_break_start or clokio_clock_out, and no conditions such as 'employee must currently be on an active break.' The only implied usage is that a break must already have been started, which is not stated.

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