TDQS

C2.9/5.0

Behavior3/5

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

Annotations already cover read-only and non-destructive behavior, so the description only needs to add concrete context beyond that. The 'cached' qualifier is useful behavior and suggests data may be stale, but the description does not explain what `refresh` does, whether it forces fresh data, or how pagination relation to cache behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded, using two sentences without unnecessary filler. The phrase 'BM links: assets_lookup_business_links' is cryptic but contributes as a pointer to a related tool, so it earns its place.

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

Completeness2/5

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

Given the low parameter coverage and five mostly unexplained properties, the description is not sufficient for reliable invocation beyond simple default calls. The output schema exists, but the missing parameter semantics and unclear refresh/filter behavior leave important gaps in contextual completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate for five undocumented parameters, but it adds only generic phrases like 'filter then paginate'. It never explains that `search` filters, `cursor`/`limit` control pagination, what `fb_user_label` does, nor what `refresh` means semantically.

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 identifies a specific verb and resource: it lists cached Pages with delivery health, which distinguishes it from related asset-listing tools like assets_list_ad_accounts and assets_list_businesses. However, it does not explicitly contrast it with sibling page-related tools such as accounts_list_eligible_pages, so it falls short of full differentiation.

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

Usage Guidelines2/5

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

The description gives a rough operating hint ('filter then paginate') and points to a related tool via 'BM links: assets_lookup_business_links', but it does not explain when to choose this tool over alternatives or when not to use it. No usage exclusions or alternate selection criteria are provided.

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