get_payslip_details_tool

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

With no annotations, the description must carry the transparency burden. It discloses the return structure (master record plus line items with examples like base pay, overtime, taxes), which is useful. However, it omits any mention of side effects (though 'get' implies read-only), error behavior, or dependency on employee context. It adds some value but not full transparency.

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 concise and well-structured: a one-sentence purpose, an Args list, and a Returns summary. Every sentence earns its place with no redundant 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?

The tool is simple (2 params, no nested objects) and has an output schema, so the description need not detail every return field. It provides an adequate summary of the return payload and clearly defines inputs. Minor gaps: it does not explain how the employee is determined or what happens if no payslip matches, but for this complexity, it is mostly 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 description coverage is 0%, so the description must compensate. It fully does so: 'mese: Month number (1-12)' and 'anno: Year (e.g. 2026)' provide both meaning and format for the two parameters, which the schema only lists as integers with titles.

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 tool's function: 'Get the full details of a specific payslip by month and year.' It specifies the verb (Get), the resource (payslip), and the scope (specific, by month/year), which distinguishes it from siblings like get_employee_summary (aggregate) and search_payslip_items (search).

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?

No guidance is given on when to use this tool versus alternatives. It does not mention exclusions, preconditions, or sibling tools like search_payslip_items or get_salary_history_tool. The context signals include siblings, but the description itself provides no usage direction.

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