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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds value by specifying exactly which stock dimensions come back and confirming it is a scoped GET, but says nothing about auth requirements, error cases for invalid ids, or freshness of the levels. No contradiction with annotations.

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 compact sentences: the field list comes first, the endpoint path second, with no filler. The raw path is mildly redundant given the tool name and schema, but it is short and harmless.

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 enumerates the return fields, which is exactly the compensating detail needed. For a read-only two-parameter tool with 100% schema coverage and full annotations, little else is missing; only edge behavior (errors, stale data) is absent.

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, including the important 'sellable is the variant id, not the product id' caveat. The description echoes the variant/warehouse scoping but adds no new 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 (get) and resource (stock level of one sellable in one warehouse) and enumerates the returned fields — physical, allocated, available, incoming, in-transit, bin location, low-stock flag. An agent can distinguish it from other getters, though it never names the obvious sibling veeqo_set_stock_level as the read/write counterpart.

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 implied by the tight scoping ('one sellable in one warehouse'), which tells the agent this is a point lookup rather than a listing, and the endpoint path reinforces the required pair. However there is no explicit when-to-use statement, no exclusions, and no routing to siblings such as veeqo_get_product or veeqo_set_stock_level.

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