`sortBy`	No	Optional sort order for returned ads.
`status`	No	Optional ad status filter.
`context`	Yes	Describe the user's underlying goal in one sentence — not the tool you are calling.

`mediaType`	No	Optional creative media filter.
`startDate`	No	Optional start date filter in YYYY-MM-DD format.
`maxResults`	No	Ignored if this tool does not support it.
`companyName`	No	Company or page name to search when you do not have a page id.

A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the read-only and external-data nature. The description adds the pagination behavior ('use cursor when paginated') and confirms it returns a list, which is useful but not extensive. Given the annotation coverage, this is acceptable but not outstanding.

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?

The description is extremely concise, with three short sentences that front-load the purpose and immediately mention the two identifier options and pagination. There is no waste or unnecessary detail.

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

Completeness3/5

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

With 20 parameters but many generic ones, the description provides just enough to know the tool's core use, but it doesn't explicitly state that either pageId or companyName is required (only 'Accepts'), nor does it describe output fields beyond 'a list'. Since there is no output schema, some additional context about the response shape would be helpful, but the description is not severely lacking.

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 description coverage is 100%, so all parameters have descriptions. The description only reiterates that it accepts a page id or company name, which is already in the schema. It adds minimal value beyond the schema, so baseline 3 is appropriate.

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

Purpose4/5

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

The description clearly states the tool lists ads a company or Page runs in the Facebook Ad Library, with a specific verb and resource. It is distinct from broader search tools, but it doesn't explicitly differentiate itself from siblings like facebook_adLibrary_ads_search_get or google_company_ads_list, so a 4 is appropriate.

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

Usage Guidelines3/5

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

The description implies usage when you have a page ID or company name, but it doesn't explicitly state when not to use this tool or mention alternatives. The context of the name and the 'Accepts a page id or company name' hint provides only implied guidance, so a 3.

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