Behavior4/5

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

Annotations already declare destructiveHint=true, but the description adds valuable context: the tool is premium-gated and requires an API key. It also states 'entirely' implying full removal. These go beyond the annotation and help the agent understand authorization and scope.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the action, and zero wasted words. Every sentence adds essential information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple destructive tool with one parameter and no output schema, the description covers the action, parameter source (implied), and necessary conditions (premium, API key). No critical gaps, and it complements the annotations and schema well.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description does not add extra meaning beyond what the schema provides for the parameter 'sealedProductUuid'; it only implies its use through context ('from inventory').

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description starts with 'Remove a sealed product from the authenticated user's inventory entirely,' clearly stating the verb (remove), resource (sealed product), and scope (from inventory). This distinguishes it from siblings like 'remove_inventory' (general) and 'list_sealed_inventory' (listing).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states 'Premium-gated. Requires IWMM_API_KEY,' providing clear context on when the tool can be used. It does not mention when not to use it or alternative tools, but the prerequisite is clearly communicated.

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