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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is fully covered. The description adds genuine value by disclosing the return shape is dotted-path keyed (e.g. widget.appearance.accent), which tells the agent how to consume the output. It stops short of describing nesting depth or completeness of the settings tree.

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 tight sentences with zero filler; the resource enumeration comes first and the cross-tool path hint follows. Nothing is wasted.

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, so the description must sketch the return contents, and it does so by listing the settings groups and explaining the dotted-path key convention. That is sufficient for an agent to call and parse it, though it could note whether all groups are always present.

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?

Only one parameter (productId) and schema coverage is 100%, with the schema stating it comes from list_products. The description adds nothing about the parameter, so the baseline 3 applies since the schema does the work.

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?

The description names the specific resources returned – help center, widget and changelog settings plus support email, time zone and language for a hosted product – which scopes it clearly against siblings like get_workspace_settings or get_widget_install. It doesn't use an explicit read verb, relying on the name, but the resource scope is unambiguous.

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?

It links itself to update_help_center_setting by noting the dotted paths it returns are exactly what that tool consumes, which is useful directional guidance. However, it never states when to call this versus other settings readers, nor any prerequisites or when-not conditions.

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