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

Annotations already cover the read-only, idempotent, non-destructive safety profile. The description adds genuinely useful behavior beyond that: the default filter (open only, excluding solved/closed), the default sort (most recently updated first), and the shape of each returned row ({id, name} people plus status_name and my_roles).

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?

Effectively two dense sentences: the first front-loads scope and defaults, the second describes row contents and gives usage cues. No filler, and the most decision-relevant information (whose tickets, default filter) leads.

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-defaulted listing tool, the description covers scope, defaults, sort behavior, and row shape, and an output schema exists so return values needn't be re-explained. Nothing an agent needs to invoke it correctly is missing.

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 100%, and each parameter already carries a clear enum and description (role, sort, order, range, fields, format, status, users_id). The description only echoes the role/scope semantics and adds no syntax or format detail beyond the schema, 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?

States a specific verb (list) and resource (my tickets) and pins the exact scope: tickets where the connected user is requester, assigned technician, or observer. This cleanly separates it from the sibling glpi_list_tickets (all tickets) without requiring the agent to open either 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?

Provides clear context and even trigger phrases ("meus chamados", "my open tickets", "tickets assigned to me") that map user intent to this tool. However it never explicitly names the alternative (e.g. glpi_list_tickets for tickets not involving me), so the when-not condition is only implied.

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