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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered elsewhere. The description adds what kind of data comes back, but says nothing about the period default (30 days), how the aggregation window behaves, or response shape — and idempotentHint=false on a read tool is left unexplained.

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 short sentences with the payload description front-loaded and no filler. The opening 'Get queue statistics' mostly restates the name/title, a minor redundancy rather than bloat.

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 usefully previews the returned metrics, which is the right call. But for a tool with a required nested request object and an unexplained time-window parameter, the definition leaves real gaps an agent would need to guess at.

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 0% and the tool wraps everything in a required nested 'request' object. The description's only nod to parameters is 'for a period', which does not clarify that withinDays defaults to 30 or that the schema permits negative values; the nested wrapper is undocumented in both places.

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?

Specific verb+resource ('get queue statistics') plus an enumeration of the returned metrics (resolved/pending items, top reviewers, resolved per day), which naturally separates it from queue-list and queue-retrieve. It never explicitly names a sibling it should not be confused with, so it stops short of the top mark.

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?

Usage is only implied: 'for a period' hints the tool answers aggregate questions about a queue, but there is no statement of when to prefer it over analytics-summary or queue-items-list, and no prerequisites or exclusions.

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