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

The readOnlyHint annotation already establishes this as a safe read. The description adds value by disclosing the row shape (product, from/to facility, quantity, lot, send/receive dates) and the underlying endpoint, but says nothing about pagination, default ordering, or the compact default field set that the schema mentions.

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 tight sentence front-loads purpose and then the returned fields, with the endpoint appended. Both clauses earn their place; only the raw path adds little for an agent that already knows the tool name.

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 compensates by naming the returned columns, but it omits result ordering, default field set behaviour, and the 30-day window semantics of the update filters that an agent must respect to call this correctly. Adequate, not complete.

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%, so limit, fields, updated_since and updated_until are all fully documented in the schema, giving a baseline of 3. The description contributes nothing to parameter meaning, and the dates it mentions (send and receive) are returned columns rather than query filters, so it cannot be credited with parameter clarification.

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 clear verb+resource (list stock transfers between locations) and enumerates the row fields returned, which pins down what the resource actually contains. It does not, however, distinguish itself from the near neighbours list_stock_changes or list_shipments, so an agent must still infer which listing covers its case.

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?

There is no when-to-use guidance at all: nothing tells the agent how this differs from finale_list_stock_changes, finale_list_shipments, or finale_get_product_stock, nor when to reach for updated_since filtering instead of a full listing. Usage is left entirely to inference from the name.

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