Record Attendance (Personio)

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

Annotations already indicate the tool is not read-only and not destructive. The description adds valuable behavioral context: it goes through an approval workflow and has a 24-hour limit per period, which aids agent decision-making without contradiction.

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 extremely concise at three short sentences, each adding distinct information: primary action, parameter hint, and behavioral trait. No redundancy or filler.

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 simple record creation tool with no output schema, the description covers core action, parameter hints, approval flow, and duration limit. It lacks details on conflict handling or editing, but remains reasonably complete.

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 low (20%), with only 'start' described. The description adds meaning for 'projectId' (tagging for WORK) and implies 'type' differentiation, but does not elaborate on 'end' format (beyond the schema) or 'comment', leaving 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 explicitly states the action (record a WORK or BREAK period), scope (for yourself), and key details (breaks are separate, projectId tagging). It clearly distinguishes from sibling tools like personio_get_my_attendances (read) and personio_request_absence (absence recording).

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 clear context for usage (recording work/break periods) and includes constraints (approval workflow, max 24h). While it does not explicitly list when not to use, the tool name and siblings make the intended use evident.

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