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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds that this is a GET on the /absences endpoint, which is minor but real context; it says nothing about pagination defaults, result ordering, or whether unpaginated calls are risky.

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 that lead with the purpose, then the endpoint. Slightly wasteful since the filter parenthetical duplicates what the schema documents, but nothing is buried or padded.

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 read-only, fully-documented, zero-required-parameter list tool with no output schema, this is close to sufficient; the safety profile and params are carried by annotations and schema. The remaining gap is that an agent gets no hint about what absence records contain or how pagination should be driven.

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 explains all six parameters including the pointer to craftboxx_list_absence_types. The parenthetical '(employee, type, start, end)' restates filter dimensions already present in the schema and adds no format or semantics beyond it.

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?

States a specific verb+resource ('List absences') and gives concrete examples of what an absence is (holiday, sick leave), plus the underlying endpoint. It does not differentiate itself from the related craftboxx_list_absence_types sibling, which is only referenced inside the schema.

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?

There is no when-to-use guidance, no exclusions, and no pointer to the sibling craftboxx_list_absence_types for discovering type ids. The agent must infer that this is the general listing tool for absences purely from the name and one-line description.

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