get_product_group

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

No annotations exist, so the description carries the full burden. It does disclose the read shape (a single group with its ordered options, values and variants), which is genuine behavioral context about the response. However, nothing is said about permissions, not-found behavior, or nesting depth, leaving meaningful gaps for a no-annotation tool.

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-loaded with the verb and resource and then the payload detail. No filler, though it is terse enough that the missing guidance is a function of under-specification rather than brevity.

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 names the returned components, which partly compensates. But with no annotations and zero parameter documentation, an agent still cannot tell what the ID should be or what could go wrong, so it is only minimally 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 0% for the single required parameter productGroupId, and the description adds nothing about its format, source, or whether it is an internal ID or a user-facing key. With only one parameter the definition should at least anchor what identifier is expected.

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 ('Get') plus resource ('one product group') and it enumerates the payload contents (ordered options, option values, attached product variants). It implicitly separates itself from list_product_groups (plural) and get_product_group_variant_quantities, but never names a sibling explicitly.

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 when-to-use guidance, no prerequisites, and no mention of the obvious alternatives (list_product_groups, get_product_group_variant_quantities). The agent must infer the selection rules from the name alone.

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