mailchimp_landing_pages_update

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

No annotations are provided, so the description carries the full burden of disclosing side effects or mutation behavior. It only says 'Update a landing page' without indicating whether it performs a partial or full update, what happens to omitted fields, required permissions, or potential irreversible changes. This is insufficient for a mutation 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?

The description is a single concise sentence with no fluff or redundancy. It is efficiently front-loaded with the core action. However, it is perhaps too abbreviated given the tool's complexity, but as a concise statement it earns credit for 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?

Given the lack of annotations and output schema, and the tool's complexity (6 parameters including a nested tracking object), the description is far from complete. It provides no information about return values, potential errors, or behavioral nuances, leaving the agent with significant gaps in understanding.

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% as every parameter has a description, but those descriptions merely prefix 'Updated' to the parameter name (e.g., 'Updated page name') and add little semantic value beyond the property names themselves. Since coverage is high, the baseline is 3, and the description adds marginal value.

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 clearly states the action 'Update' and the resource 'a landing page', which is specific enough to distinguish from list/get/create/delete/publish/unpublish operations among siblings. However, it does not elaborate on what fields can be updated, which would further clarify the tool's scope.

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 guidance on when to use this tool versus alternatives. No mention of prerequisites, whether to use this for modifying existing pages versus create for new ones, or any exclusion context. The description simply states the action without usage context.

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