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

Annotations already declare readOnly, idempotent, non-destructive, open-world access, so safety is covered. The description adds only that pagination is optional; it does not disclose default page size, ordering, or what openWorld implies (e.g., live GLPI calls). A 3 is appropriate given annotations carry most of the burden.

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?

A single short sentence front-loads the resource and purpose with zero filler. Nothing could be removed without losing meaning.

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?

With annotations covering safety and a 100%-covered schema, the description is minimally adequate. It omits how entities are scoped (root vs. active), ordering, and why a user would choose this over glpi_get_my_entities, leaving real gaps for a list tool.

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 every parameter has a description, so the schema does the work; the description only mentions pagination generically. Baseline 3 is the correct ceiling here.

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 (List) and resource (GLPI entities, glossed as organizational units), which is clear enough to act on. It does not differentiate itself from siblings like glpi_get_entity, glpi_get_my_entities, or glpi_list_my_tickets, so it falls short of a 5.

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 says nothing about when to use this list tool vs glpi_get_entity (single item), glpi_get_my_entities (scoped to user), or other list tools. Only the phrase 'optional pagination' hints at context; no alternatives or exclusions are named.

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