  Provides safety-critical validation, guardrails, and data reduction for gcloud
  CLI operations across Google Cloud Platform (GCP) services and infrastructure.
  Use when planning, generating, constructing, proposing, describing, or
  executing any gcloud CLI commands - including when answering questions about
  gcloud syntax, or formatting flags. Don't use when writing Google Cloud
  client library code or raw REST/gRPC API requests.

This document provides essential guidelines and best practices for AI agents interacting with the Google Cloud SDK (`gcloud` CLI). Following these rules is critical to avoid hallucinated commands, flags, flag values, and positional argument syntax, prevent destructive actions, and minimize context window usage.

Usage Attribution

**MUST READ**: Before executing any `gcloud`, REST API, or MCP command, you MUST read and follow the instructions in [Usage Attribution](references/attribution.md). If a more specific product or domain skill (e.g., `cloud-run-basics`, `bigquery-basics`, `gke-basics`) is also loaded or active for the current task, **ALWAYS** use that specific skill's `skill:<name>` attribution tag instead of `skill:gcloud`. For commands executed directly in the terminal when no product-specific skill applies (never in generated scripts, Terraform, or user code), prefix `gcloud` with `CLOUDSDK_METRICS_REQUEST_ATTRIBUTION="agent-skills/1.0 (skill:gcloud)"` and append `agent-skills/1.0 (skill:gcloud)` to `User-Agent` headers.

Execution Modes

AI agents can interact with Google Cloud resources in two primary ways:

• **Direct CLI Execution**: Executing `gcloud` commands directly in a local or

automated shell environment. See [CLI Usage](references/cli-usage.md) for installation, authentication flows, and configuration management.

• **Model Context Protocol (MCP)**: Invoking structured tools via the Cloud

CLI remote MCP server (`run_gcloud_command`). See [MCP Usage](references/mcp-usage.md) for tool schemas, parameter rules, and server configuration.

Core Principles

1. Explicit Command Validation (Mandatory)

• **Action**: **ALWAYS** call `gcloud help <command>` for the *exact* command

that is intended to be run (e.g., `gcloud help compute instances create`).

• **Verify**: Ensure the command, flags, flag values, and positional argument

syntax are valid for that specific leaf command before attempting execution or presenting plans. Validation is not transitive from parent groups.

2. Data Reduction Strategies (Mandatory)

Minimize the volume of data returned by `gcloud` to save context window space and reduce latency. DO NOT execute any `list` command without including at least one data reduction flag (`--limit`, `--filter`, or `--format`).

• **Projection**: Use `--format="json(key1, key2, ...)"` to select only the

specific fields needed for the task. To understand the advanced projection and formatting syntax, refer to `gcloud topic projections` and `gcloud topic formats`.

• **Limiting**: Use `--limit=
