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

There are no annotations, so the description carries the full burden. It only says 'List' which implies read-only, but it does not disclose pagination behavior via limit/cursor, whether ad_account_id is required or how it scopes results, or any details about the response. The added note about sheet contents is about the resource, not the tool's runtime behavior.

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 two short sentences. The first states the core action and scope, and the second adds a useful clarification of what ad sheets are. There is no fluff or redundant wording.

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 three optional parameters and no output schema or annotations. An agent needs at least pagination context and the role of ad_account_id to invoke it correctly in varied situations. The current description, while clear on purpose, is too sparse to be fully actionable.

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 0% and the description provides no information about the three parameters (limit, cursor, ad_account_id). Since the schema itself supplies no descriptions and the description does not compensate, all parameter semantics are left to the agent to guess.

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 states a specific action and resource: 'List bulk ad creation sheets for an ad account.' It also explains what sheets are ('rows of ad configurations'), which clarifies the object. It doesn't explicitly contrast with siblings like list_ad_sets or get_ad_sheet_schema, but the term 'bulk ad creation sheets' is distinctive enough to avoid major confusion.

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 given about when to use this tool versus alternatives such as list_ad_sets, list_ad_templates, or get_ad_sheet_schema. The description merely implies the obvious case of listing ad sheets, with no context or exclusions.

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