mailchimp_ecommerce_products_update

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

There are no annotations, so the description must carry the behavioral disclosure burden. It only says 'Update a product', which implies mutation but does not explain whether the update overwrites existing fields, requires the product to exist, or has any side effects. This is minimal transparency for a write operation.

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?

The description is concise (one sentence) but under-specified. For a tool with six parameters and no other documentation, this brevity sacrifices necessary detail. It fails to be appropriately sized for the tool's complexity.

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?

The tool has no output schema, no annotations, and a sparse description. It does not disclose update semantics, parameter relationships, return values, or any operational context. This is completely inadequate for a tool with six parameters and a data-modifying operation.

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%, with each parameter having a basic description (e.g., 'Updated URL', 'Store ID'). The tool description adds no additional parameter semantics, but the schema already provides adequate meaning, so the baseline score of 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?

The description 'Update a product' identifies a specific action (update) and resource (product), but it does not specify that this is for ecommerce products or mention the store context. While the tool name disambiguates, the description alone is vague and does not distinguish from other update tools in the sibling set.

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 guidance is provided about when to use this tool versus alternatives. The description simply states the action, with no mention of prerequisites, scenarios, or exclusions. Sibling tools like mailchimp_ecommerce_products_add or mailchimp_ecommerce_products_delete are not referenced.

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