approve-timesheet

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool approves a timesheet, implying a mutation operation, but does not disclose critical traits like required permissions, whether the action is reversible, side effects (e.g., triggering payroll processing), or rate limits. This leaves significant gaps in understanding the tool's behavior.

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, direct sentence with no wasted words, front-loading the key action and resource. It efficiently conveys the core purpose without unnecessary elaboration, making it easy for an agent to parse quickly.

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 the complexity of a mutation tool (approving payroll timesheets) with no annotations and no output schema, the description is incomplete. It lacks details on behavioral traits, usage context, and expected outcomes, which are critical for an agent to invoke the tool correctly and safely in a real-world scenario.

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?

The input schema has 100% description coverage, with the parameter 'timesheetID' fully documented. The description adds no additional semantic meaning beyond the schema, such as format examples or constraints (e.g., ID must be from Xero). With high schema coverage, the baseline score of 3 is appropriate, as the description does not compensate but also does not detract.

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 the action ('Approve') and resource ('a payroll timesheet in Xero'), making the purpose specific and understandable. However, it does not explicitly differentiate from sibling tools like 'revert-timesheet' or 'update-timesheet-line', which would require mentioning what 'approve' entails (e.g., finalizing for payroll vs. editing).

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 provides no guidance on when to use this tool versus alternatives, such as 'revert-timesheet' or 'update-timesheet-line', nor does it mention prerequisites (e.g., the timesheet must be in a draft state). It lacks explicit context for usage, leaving the agent to infer based on the tool name alone.

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