e2e_get_k8s_cluster

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. 'Get' implies a read, but there is no mention of permission requirements, behavior on unknown/missing service IDs, or whether location/project_id narrow the lookup - all left unstated for a tool with zero annotation coverage.

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 wasted words. Size is appropriate for the small parameter surface, though it is arguably too terse for a tool with no annotations.

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 3-parameter read with full schema coverage and no output schema, the description is minimally adequate. It omits any behavioral or usage context, leaving gaps that annotations would normally 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?

Schema description coverage is 100%, so the schema already documents location, project_id, and service_id; the description only echoes service_id as the lookup key. Baseline 3 applies since the schema does the heavy lifting, though the description adds nothing about why location/project_id are optional companions.

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 (Get) and resource (managed Kubernetes cluster) with the lookup key (service ID). It is clearly a single-item fetch, implicitly distinct from the sibling e2e_list_k8s_clusters, though that distinction is never made explicit.

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, prerequisites, or named alternatives are given. The agent must infer that this is the detail-view counterpart to e2e_list_k8s_clusters rather than being told.

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