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

Annotations already establish readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful context about what is returned: current state, current shift, clockable shifts, and startable breaks, plus the underlying GET endpoint. It does not discuss auth or rate limits, but it goes beyond structured annotations for a read-only status call.

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?

Two compact sentences with no filler. The core state information is front-loaded, followed by the prerequisite for the required parameter and the endpoint. Every sentence contributes useful content.

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 single-parameter read tool with no output schema, the description adequately explains the return content (current state, current shift, available clock-ins and breaks), the required job id and where to get it, and the endpoint. Annotations cover the safety semantics, so little is missing for correct invocation.

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 coverage is 100% and the job_id parameter is fully documented in the schema. The description adds meaning by specifying that the job id is the `job.id` of an employee obtainable from homebase_list_employees, giving an agent a clear source for the required value.

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 names a specific verb+resource: retrieves the current time-clock state of one job, and enumerates the state values (clocked_in, on_break, clocked_out). It also distinguishes the job concept by pointing to homebase_list_employees for obtaining the job id, helping separate it from sibling employee and shift tools.

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?

Usage is implied by the stated purpose, and the description gives a prerequisite: the job id comes from homebase_list_employees. However, it does not explicitly say when to use this tool versus alternatives such as homebase_get_timecard, homebase_get_shift, or list tools, nor does it provide when-not guidance.

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