e2e_create_vpc

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

With no annotations provided, the description carries the full behavioral burden but discloses almost nothing: it does not state permission requirements, whether creation is idempotent, what happens on name collision, or how CIDR assignment interacts with is_e2e_vpc. For a mutating create operation this is a significant gap.

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 zero waste and no redundancy. It is efficient, though the terseness edges toward under-specification rather than optimal economy.

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 fully documented schema covers parameter-level needs, so an agent can construct a valid call. But for a mutating tool with no annotations and no output schema, the description leaves behavioral context (permissions, outcomes, prerequisites) unaddressed.

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 all five parameters (ipv4, location, vpc_name, is_e2e_vpc, project_id) with examples and defaults. The description adds no parameter meaning beyond that, so the 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?

States a specific verb (Create) and resource (Virtual Private Cloud network), which clearly distinguishes it from siblings like e2e_list_vpcs and e2e_delete_vpc. However, it offers no explicit differentiation text against those siblings, so the reader must infer from the name alone.

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 gives no when-to-use guidance, no prerequisites, and never references alternatives such as e2e_list_vpcs or e2e_delete_vpc. An agent gets no help deciding whether this is the right tool or what conditions must hold before calling it.

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