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

No annotations are provided, so the description carries the full burden; 'List' plus '(unpublished by default)' does establish that this is read-only and that the default scope excludes published items, which is real behavioral context. However, it says nothing about pagination, result limits, or permissions, which matters for a listing tool with no annotations.

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 sentence with zero filler, and the scoping plus default behavior are front-loaded. Nothing is redundant with the name or title.

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?

For a simple two-parameter read tool with no output schema and no annotations, the description covers purpose and the default filter but omits return shape and whether results are paginated or bounded. Adequate but leaves gaps an agent may care about when drafting a call plan.

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 coverage is 50%: product_id is documented in the schema, while the published boolean has no schema description at all. The description fills exactly that gap by declaring the default filtering behavior, so an agent knows that omitted published means drafts-only.

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?

States a specific verb (List) and resource (staged article drafts) scoped to a product, which is far more informative than the bare tool name. It doesn't explicitly name a sibling or carve out a boundary against publish_content or list_products, so it stops short of a 5.

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?

The phrase 'unpublished by default' implies the tool's role in a draft-review workflow, but there is no explicit statement of when to use this versus related tools like publish_content or list_products. Usage is inferable rather than stated.

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