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

The annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered structurally. The description adds only that results are scoped to the authenticated store, which is modest but real added context; nothing is said about ordering, completeness, or whether custom statuses are included.

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 zero waste: the purpose is front-loaded and the endpoint follows as supporting detail. Nothing could be removed without losing information.

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, parameterless lookup with no output schema, the description conveys enough to invoke it correctly, and the phrase 'status names' implies the return shape. A brief note on per-store scoping being derived from configuration rather than an argument would make it fully self-contained.

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 tool takes zero parameters and the description correctly introduces none, so there is nothing to mismap. Baseline 4 applies for a parameterless tool with 100% schema coverage.

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-plus-resource: it returns the store's available ticket status names, and the 'GET /statuses' endpoint confirms the exact backend resource. It is clearly distinct from sibling list_* tools (tickets, invoices, employees), though it never explains what a 'ticket status' is used for in this API.

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 explicit when-to-use guidance, no mention that these status names are typically needed to filter or interpret repairdesk_list_tickets results, and no alternatives or exclusions given. The lookup purpose is only inferable from the phrase 'available ticket status names'.

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