e2e_list_k8s_clusters

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, and it discloses very little. 'List all' weakly implies a read-only, non-destructive call, but there is no mention of pagination, result limits, auth/credential requirements, or whether an empty result is possible.

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 the verb, scope, and resource in the first few words. No filler, no redundancy; every word earns its place.

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 simple two-optional-parameter list tool with a fully described schema and no output schema, the description is minimally viable. However, with no annotations and no output schema, it leaves gaps around pagination, return contents, and credential requirements that the structured fields do not cover.

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?

Both parameters (location, project_id) are fully documented in the schema at 100% coverage, so the baseline is 3. The description adds nothing about how location or project_id affect the listing (e.g. filtering or defaulting), so it neither compensates nor detracts.

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 ('List all managed Kubernetes clusters') and scopes it to the E2E Cloud project, so an agent knows this is a bulk retrieval, not a single-cluster lookup. It stops short of naming siblings like e2e_get_k8s_cluster or e2e_list_k8s_node_pools, so differentiation is left to inference from the names.

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?

There is no explicit when-to-use statement, no prerequisites, and no routing to alternatives. The 'List all ... in your project' phrasing implies a read/list context, but the agent gets no guidance on when to prefer this over e2e_get_k8s_cluster or e2e_list_k8s_node_pools.

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