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

readOnlyHint=true already establishes the safety profile, yet the description still adds real value by enumerating the returned payload fields (codename, approval/note requirement, hour-vs-day mode, duration limits) — significant given there is no output schema. It stops short of describing not-found/error behavior or any permission constraints.

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 tight sentences with the most useful content (the returned fields) front-loaded. The trailing raw endpoint path is slightly redundant but standard and harmless.

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 single-parameter, read-only lookup with no output schema, the field enumeration is the key missing piece and it is present. Minor gaps remain: no guidance on what happens for an unknown/foreign-company UUID.

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% and the parameter description itself explains the UUID format and points to jethr_list_absence_policies for sourcing it. The description adds nothing beyond that, so the baseline 3 applies.

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 names the specific resource (a single absence request kind setting) and enumerates the attributes it exposes, so an agent knows exactly what it retrieves. It does not explicitly contrast itself with the sibling jethr_list_absence_policies, though the singular/plural distinction is inferable.

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 statement of when to use this tool versus jethr_list_absence_policies or why a single-fetch is preferable. The only routing hint (where to obtain the uuid) lives in the schema's parameter description, not in the tool description itself.

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