Create GCP project

gcp_create_project

Create a new GCP project under an organization or folder using your credentials. Use it when you need to provision a fresh project and require resourcemanager.projects.create permission.

Instructions

Creates a new GCP project. The caller's credentials need resourcemanager.projects.create permission (typically requires org/folder-level access, not just a service account scoped to one existing project).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

B3.3/5.0

Behavior3/5

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

With no annotations, the description carries the full burden and does surface the most consequential behavior: the required resourcemanager.projects.create permission and the org/folder-level access it typically implies. It stops short of covering defaults applied to the new project, reversibility, or quota/rate behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero waste, action front-loaded followed by the critical caveat. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no annotations and no output schema, the description covers the key failure mode (insufficient permissions) but omits what a successful call produces, side effects, or the meaning of the parent fields. Adequate but with clear gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

At 50% schema coverage the schema already documents newProjectId's format and parentId's relation to parentType, and the parentType enum is self-describing. The description adds no parameter meaning, but only displayName is truly undocumented, so the baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Creates a new GCP project'), which is unambiguous and clearly distinct from the read/delete/undelete siblings. It does not, however, explicitly name or contrast itself with an alternative the way a 5 would require.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description never says when to use this tool versus alternatives or what conditions trigger it. The permission note is a prerequisite, not usage guidance, so an agent gets no routing help.

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