e2e_list_projects

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

No annotations are provided, so the description carries the full behavioral burden. 'List' implies a read-only operation, but there is no disclosure of pagination, result caps, permission requirements, or whether the caller needs project membership to see anything. Only the basic read semantics are inferable.

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 front-loaded sentence with no filler. It earns its place, though the compound 'projects and access control scopes' phrasing slightly muddies what is actually returned.

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 annotations and no output schema, the description should do more: it does not describe the shape of the response, whether scopes are nested under projects, or how results behave when location is omitted. For a simple one-optional-param list tool this is minimally adequate rather than 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?

There is a single optional parameter (location) and schema description coverage is 100%, so the schema already explains the region-scoping behavior fully. The description adds nothing about the parameter, but the baseline of 3 is appropriate when the schema does the work.

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 (List) and a specific resource (IAM projects and access control scopes) in the E2E Cloud account. It is unambiguous against siblings, which all target other resources (nodes, buckets, databases). Slight ambiguity in whether projects and scopes are two separate result sets, but the purpose is clear.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives. It is implied that this is the entry-point listing for projects, but nothing tells an agent when this should be preferred over, say, e2e_raw_request or how it relates to account setup tools like e2e_configure_credentials.

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