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

Annotations already mark it read-only/safe, and the description adds value on top: SkuVault throttles this call to 1 per minute, which is operationally critical and not in any structured field. It also discloses the exact endpoint, reinforcing it is a query despite the POST verb.

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?

Three short sentences, each carrying a distinct payload: what it returns, why the Id matters, and the rate limit. Front-loaded and zero waste.

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?

No output schema exists, but the description names the returned fields (Id and Code) and surfaces the throttling constraint, which is the main correctness risk. Minor gap: nothing about multi-page behavior or how many warehouses typically return.

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 the single page parameter is fully documented in-schema including the next.page paging convention. The description adds nothing about paging, 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?

Specific verb+resource ("List the regular warehouses") plus the returned fields (Id and Code), so the agent knows exactly what it gets. The word "regular" hints at a distinction from location-style tools (skuvault_list_locations), but it never names that sibling, so differentiation is only implied.

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?

Gives a concrete reason to call it: the numeric Id is required by the stock tools and skuvault_list_transactions, which is real when-to-use guidance. It stops short of stating when not to use it or which sibling to prefer for location/who-data.

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