Get All Time Off For A Single Person

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

Annotations already indicate readOnly, non-destructive, idempotent, and open world. The description adds 'Returns a JSON object' but does not disclose pagination behavior, rate limits, or other side effects beyond the annotations.

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 includes an API endpoint line that may be useful but adds length. The first sentence is clear, but subsequent sentences are somewhat redundant and could be more 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?

The description lacks explanation of pagination (despite schema having limit, start_after, page, per_page) and does not clarify the scope of 'all Time Off entries' (e.g., date range). No output schema, so more detail on return structure is needed.

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%, so the schema already documents all parameters. The description only mentions required parameters without adding meaning beyond the schema descriptions. Baseline score of 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 'Retrieves all Time Off entries for a specified Person within a company,' providing a specific verb and resource. However, it conflates with 'Resource Planning records' and doesn't differentiate from sibling tools like 'get_single_time_off_record'.

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 says 'Use this to fetch the full details of a specific Resource Planning records by its identifier,' but offers no guidance on when to use this tool versus alternatives. No exclusions or context about when not to use it.

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