iaas_get_projects_by_id_zones

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that results are returned in pages, which is behavior beyond what annotations state, but it omits return shape and whether unpaged calls return everything.

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?

Three short lines with the purpose stated first, followed by the paging note and the raw endpoint. There is no filler, though the endpoint line largely duplicates the annotation 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 read-only paginated list tool with a fully documented six-parameter schema and complete annotations, the description covers purpose and paging adequately. No output schema exists, but describing the returned zone-assignment structure would have closed the remaining gap.

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 100%, so every parameter including top, skip, count, and filter is already documented in the schema. The description's only semantic contribution is the word 'pages', which loosely ties to top/skip; otherwise it adds nothing beyond the schema, so baseline 3 applies.

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 verb and resource: get all zones assigned to a project, and includes the underlying path GET /iaas/api/projects/{id}/zones. It is clear what the tool returns, but it does not distinguish itself from nearby siblings such as iaas_get_zones or iaas_get_project, so an agent must infer which one matches its need.

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 'by pages' implies the paginated nature of the retrieval and hints at using top/skip, which is useful implied guidance. However, there is no explicit statement of when to use this tool versus iaas_get_zones (all zones) or iaas_update_project_zone_assignments (mutation), and no prerequisites are given.

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