From Empty Folder to Deployed Agent: Google's Agents CLI, Command by Command

Google's Agents CLI shipped August 3. Here's the whole loop — install, scaffold, run locally, evaluate, deploy, publish — with the real commands, so you can take an ADK agent from an empty folder to a Google Cloud runtime in one sitting.

The takeaway

Google's Agents CLI (shipped Aug 3, 2026) is the missing lifecycle wrapper around the Agent Development Kit: scaffold, run, eval, deploy, publish, observe — from one terminal. This is the copy-paste loop.
Install once with `uvx google-agents-cli setup`. That both makes the `agents-cli` command available and injects seven skills into your coding agent, so you can run every step by hand or let Claude Code / Codex drive it from a prompt.
The lifecycle: `agents-cli scaffold billing-bot` creates an ADK project; `agents-cli run "..."` executes a single prompt locally so you see it work before you pay for anything; `agents-cli eval generate` then `eval grade` turn ad-hoc testing into a scored regression gate; `agents-cli deploy` ships to Agent Runtime, Cloud Run, or GKE Autopilot; `agents-cli publish gemini-enterprise` registers it for org discovery.
The two steps founders skip and shouldn't: run the eval gate before every deploy (an agent that regressed silently is worse than no agent), and pick your deploy target on utilization, not habit — Agent Runtime for managed hosting, Cloud Run for bursty low-traffic, GKE Autopilot when you already run a cluster.

At a glance

Agent Runtime vs Cloud Run vs GKE Autopilot — compared at a glance
Deploy target	Agent Runtime	Cloud Run	GKE Autopilot
What it is	Managed hosting purpose-built for ADK agents	Serverless containers, scale-to-zero	Managed Kubernetes, no node ops
Reach for it when	Default — you just want the agent hosted and governed	Bursty, low-traffic agents where idle should cost ~nothing	You already run a cluster and want the agent beside your workloads
Scaling model	Managed by the platform	Scales to zero between requests	Pod autoscaling on your cluster
Ops burden	Lowest — Google runs it	Low — you own the container, not the infra	Highest of the three — you own the cluster
Deploy command	`agents-cli deploy` (Agent Runtime target)	`agents-cli deploy` (Cloud Run target)	`agents-cli deploy` (GKE target)
Best for	Most teams, most agents	Spiky internal tools, prototypes with real users	Platform teams standardizing agents on existing GKE

Google's Agents CLI shipped on August 3, 2026, and the fastest way to understand it is to run the whole loop once. It's the lifecycle wrapper the Agent Development Kit was missing: scaffold → run → eval → deploy → publish → observe, all from one terminal. This is the copy-paste path from an empty folder to a live agent on Google Cloud. Every command below is real; substitute your own project id and region.

0. Install (once)#

Google standardized on uv for Python packaging, so install that first, then set up the CLI:

# install uv (macOS/Linux)
curl -LsSf https://astral.sh/uv/install.sh | sh

# install + wire the Agents CLI
uvx google-agents-cli setup

That one setup does two things: it makes the agents-cli command available, and it injects seven skill modules — workflow, adk-code, scaffold, eval, deploy, publish, observability — into whatever coding agent you use. If you only want the skills (no global tool), add them straight to your agent instead:

npx skills add google/agents-cli

From here you can run every step by hand, or hand the whole thing to Claude Code / Codex with a single prompt. We'll do it by hand so you can see each seam.

1. Scaffold the ADK project#

agents-cli scaffold billing-bot
cd billing-bot

This lays down an ADK project — the open-source, code-first Python framework where your agent's logic lives. You edit the agent definition here (its instructions, tools, and model choice). The CLI owns everything around that file; ADK owns the file itself.

2. Run it locally before you pay for anything#

agents-cli run "A customer was double-charged for the Pro plan. What are our options?"

run executes a single prompt against your agent locally. This is the cheapest possible feedback loop — you confirm the agent wires up, calls the tools you gave it, and produces something sane before a single cloud resource exists. Don't skip it. The most expensive bugs are the ones you deploy first and discover in production logs.

3. Turn ad-hoc testing into a gate#

Two commands convert "I tried a few prompts" into a scored regression check:

agents-cli eval generate      # build an evaluation set from example interactions
agents-cli eval grade         # score the current agent against that set

An agent that regressed silently is worse than no agent — it fails on the prompts you stopped checking. The eval gate is the difference between shipping and gambling.

eval generate builds a set of test cases; eval grade scores your current agent against them and gives you a number to hold the line at. Wire eval grade into CI and no deploy goes out below your bar. If you want the deeper argument for why this step is non-negotiable, we made it in How to Evaluate an AI Agent's Memory — the discipline generalizes.

4. Deploy — and pick the target deliberately#

agents-cli deploy

deploy ships to a Google Cloud runtime. You have three targets, and the right one is a function of traffic shape and existing infrastructure, not habit:

Agent Runtime — managed hosting purpose-built for ADK agents. The default; reach for it unless you have a reason not to.
Cloud Run — bursty, low-traffic agents where scale-to-zero keeps the bill near zero between requests.
GKE Autopilot — you already run a Kubernetes cluster and want the agent to live beside the rest of your workloads.

The decision mirrors every other serving question we've covered: hosting economics come down to utilization, not sticker price. A managed runtime you keep busy beats a self-managed cluster you underfill.

5. Publish for discovery (optional)#

agents-cli publish gemini-enterprise

If other people or agents in your org need to find this agent, publish registers it in Gemini Enterprise. Skip it for a personal tool; run it when the agent is a shared service and discoverability matters.

The whole loop, once#

uvx google-agents-cli setup
agents-cli scaffold billing-bot && cd billing-bot
agents-cli run "test prompt"
agents-cli eval generate && agents-cli eval grade
agents-cli deploy
agents-cli publish gemini-enterprise    # if it's a shared service

Six commands from empty folder to a governed, observable agent on Google Cloud. The observability is already wired — the seventh skill (observability) plumbs Cloud Trace and logging into the deployed agent, so you're not adding instrumentation after the fact.

Two things to internalize before you standardize on this: run the eval gate before every deploy (step 3 is the one founders skip and regret), and remember the whole path is Google Cloud only — the convenience of deploy resolving to GCP by reflex is exactly the coupling you're accepting. If you want the strategic read on why Google shipped this as skills-inside-your-agent rather than a standalone product, that's the companion piece.

Frequently asked

How do I install Google's Agents CLI?

Install `uv` first (Google's chosen Python package manager), then run `uvx google-agents-cli setup`. That single command makes the `agents-cli` command available and injects seven skill modules into your coding agent. If you only want the skills side, `npx skills add google/agents-cli` adds them to Claude Code, Codex, or Antigravity CLI without a global install.

Do I need ADK to use the Agents CLI?

Yes — agents are built with Google's Agent Development Kit (ADK), the open-source, code-first Python framework. The Agents CLI is the lifecycle wrapper around ADK: it scaffolds the ADK project, evaluates it, deploys it, and wires observability. You write the agent's logic in ADK; the CLI handles everything around it.

What's the minimum path from nothing to a deployed agent?

Four commands: `agents-cli scaffold my-agent` to create the project, `agents-cli run "a test prompt"` to confirm it works locally, `agents-cli deploy` to ship it to a Google Cloud runtime, and — if others need to find it — `agents-cli publish gemini-enterprise` to register it. The eval step is optional to *run* but not optional if you value your weekend.

Where should I deploy — Agent Runtime, Cloud Run, or GKE Autopilot?

Agent Runtime is the managed hosting purpose-built for ADK agents; reach for it first unless you have a reason not to. Cloud Run suits bursty, low-traffic agents where scale-to-zero saves money. GKE Autopilot makes sense when you already run a Kubernetes cluster and want the agent to live beside the rest of your workloads. Decide on traffic shape and existing infrastructure, not habit.

Can my coding agent run all of this for me?

Yes — that's the point of the skills. Once installed, a prompt like 'scaffold a support agent, generate an eval set, and deploy it to Agent Runtime' lets Claude Code or Codex call the same `agents-cli` commands in sequence. The skills give the agent the ADK patterns and the correct invocations so it doesn't guess.
