list_pages_projects

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The verb 'List' implies a read-only operation, but the description adds nothing beyond what the tool name already conveys. It does not disclose pagination behavior, response shape, permission requirements, or whether results are limited in any way.

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?

A single clean sentence with zero wasted words. The core subject, action, and scope are all front-loaded. For a simple one-parameter list operation, this is an appropriately sized description.

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 is simple (1 required parameter, no nested objects, no output schema), and the description is mostly adequate for that simplicity. However, it does not mention pagination or response composition, and it relies entirely on sibling naming to disambiguate from get_pages_project. With no annotations, a bit more behavioral context would make it fully complete.

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%: account_id is fully documented with type, maxLength, and description 'The account ID'. The description's 'in an account' loosely maps to this parameter but adds no format, syntax, or semantic detail beyond the schema. Baseline 3 is appropriate since the schema does the heavy lifting.

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 'List Cloudflare Pages projects in an account' states a specific verb, resource, and scope. It clearly identifies what the tool does and is not a tautology. However, it does not explicitly differentiate itself from close siblings like get_pages_project or list_pages_deployments, relying instead on naming conventions.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention that get_pages_project would be used for a single project, nor does it offer any exclusions or selection criteria. The phrase 'in an account' implies account-scoped usage but that is minimal context, not real routing guidance.

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