clokio_clock_in

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

Annotations only state readOnlyHint=false, confirming a mutation, but the description adds two important behavioral constraints: PIN may be required depending on org configuration, and timestamps are clamped to ±10 minutes of server time. These go beyond the annotations and help the agent predict system behavior, though return values and side effects are not disclosed.

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 concise sentences with no fluff. The primary action is front-loaded, and the secondary constraints (PIN and timestamp clamping) follow immediately. Every clause contributes meaning, demonstrating exemplary economy.

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?

The tool is simple with three parameters and no output schema. The description covers the PIN condition and timestamp clamping, but omits any explanation of what a successful clock-in returns and does not address location_id. For a mutation tool with minimal annotations, this is a moderate level of completeness – usable but with clear gaps that an agent might need to infer.

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 by explaining each parameter. It clarifies that pin may be required, which is useful, but it says nothing about location_id or the expected format of employee_code. The description only partially addresses the parameter semantics, leaving significant gaps.

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 verb and resource – 'Clock an employee in' – which clearly distinguishes it from sibling actions like clokio_clock_out and clokio_break_start. The action is unambiguous and the resource is explicit, leaving no room for misinterpretation.

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 description clearly implies when to use this tool (clocking an employee in) and notes a precondition (PIN may be required), but does not explicitly list alternatives or exclusions. The context is clear enough that an agent can route correctly without confusion, though explicit alternatives would be stronger.

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