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

With no annotations the description carries the full burden. It usefully discloses ordering (by in-link), the pagination cap (max 100), the returned diagnostic fields, and that structural_cluster appears only in the AI view. It omits read-only/auth/permission context and any indication of what happens with an invalid cluster ID.

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?

Purpose is front-loaded, but the middle is a long comma-separated enumeration of ~17 returned fields that reads as a data dump. Every field earns some place given no output schema, yet the run-on single sentence is heavier than it needs to be.

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?

With no output schema, enumerating the diagnostic fields and the view-dependent structural_cluster is genuinely helpful and makes the return shape intelligible. It still omits defaults and a few parameter semantics, but is fairly complete for a paginated cluster-listing tool.

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 only 33%, so the description must compensate. It adds meaning for view (AI exposes structural_cluster) and pagination (max 100 implies limit), and reinforces cluster/site scope, but leaves limit/offset/lang/project_id and the auto vs structural view distinction largely to the thin schema.

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 and resource: pages of a cluster/silo (or the whole site) sorted by in-link. The cluster/silo scope and the get_topical_architecture reference make it distinguishable from generic listing siblings like find_pages, though the long field enumeration dilutes the core purpose.

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?

Implies usage (inspect pages within a cluster/silo or across the site) and notes the AI view unlocks structural_cluster, but gives no explicit when-to-use or when-not-to-use versus siblings such as get_topical_architecture or find_pages. The choice of scope comes through, not the choice of tool.

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