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

Annotations already cover safety (readOnly, idempotent, non-destructive), and the description adds genuinely new behavioral detail: aggregation into one entry per thing/event with counts, newest-first ordering, and the unread default. It doesn't mention whether archived items are reachable, which is the one remaining gap.

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 dense sentence that front-loads what the tool returns and then the default filter. The 'docket's inbox' framing is slightly decorative but costs little.

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 no output schema, the description does the necessary work of explaining entry granularity (one per thing and event, with counts) and sort order. Archived-notification behavior is the only thing an agent might still wonder about.

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 both parameters are already documented. The description only reinforces the include_read default ('unread only unless asked otherwise') and adds nothing about the limit cap or ordering interaction.

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 concrete resource and enumerates its contents (comments, mentions, assignments, closed/reopened tickets, document status changes), which clearly separates it from siblings like my_tickets or get_ticket. It never explicitly names an alternative, so it stops just 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?

'Unread only unless asked otherwise' implies the default usage context, but the description never says when to reach for this versus my_tickets, get_ticket, or my_week. Usage is inferable rather than stated.

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