list_reservable_items

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

With no annotations, the description carries the full behavioral disclosure burden. It does disclose the default itemtype and the shape of returned data, which is useful. However, it does not mention whether the operation is read-only, whether results are paginated or limited, or any authentication/access requirements.

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 two short, focused sentences with no filler. The primary action and default behavior are front-loaded, and the return fields are stated in a compact list. Every sentence earns its place.

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 two-optional-parameter listing tool with no output schema, the description is mostly complete: it explains the search scope and the returned data. It could be improved by noting pagination, result limits, or behavior when no items match, but the core agent-facing information needed to invoke and interpret the tool is present.

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?

The input schema already provides full descriptions for both the filter and itemtype parameters, including the default itemtype. The description adds context about returned fields and the ReservationItem link but does not materially deepen parameter semantics beyond the schema, so the baseline 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 the tool searches GLPI for reservable assets, names the default itemtype, and lists the returned fields. It is distinguishable from sibling tools like check_availability and reserve_cluster because it is scoped to GLPI reservation items rather than cluster operations, though it does not explicitly name a sibling alternative.

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 such as check_availability or find_available_cluster. The description implies a search/listing use case but does not state exclusions, prerequisites, or conditions that would route an agent to a different sibling tool.

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