What is Google Agent Skills?
google/skills is Google's own repository of Agent Skills, the SKILL.md format that coding agents load when a task matches. It holds 195 skills: 173 for Google Cloud (GKE, BigQuery, Cloud Run, IAM, Security Command Center, SecOps, the Well-Architected Framework and more), 14 for Google Ads and the Mobile Ads SDK, two for the Google Analytics APIs, plus a Firebase basics skill, identity skills and a Rust migration guide.
You install skills with npx skills add google/skills and pick which ones and which agents to configure. The repo is also a plugin marketplace for Claude Code and Codex with 17 plugins that bundle skills and MCP servers for AlloyDB, BigQuery, Cloud SQL, Spanner, Looker and others. It launched at Google Cloud Next 2026 with 13 skills and is licensed Apache-2.0.
Is Google Agent Skills worth it?
Google treats these skills as products rather than notes. Its October write-up describes six automated gates before a change reaches GitHub, including linters, a required version bump for any change in behaviour, link checks and an eval report comparing the agent with and without the skill, followed by human review. The repo reflects that discipline: each skill carries a semantic version, SKILL.md bodies stay short and detail sits in a references folder. With about 24,100 stars and 2,000 forks in seven months, it has become the default source for agents working on Google Cloud.
Coverage is deep where Google's own teams care and thin elsewhere. GKE alone has dozens of skills, many for specific TPU and node failures, while advertising gets 14 and Analytics two. Workspace, Maps, Android and Firestore live in separate repos that the README links to. There are no tagged releases; skills do not update themselves, and npx skills update pulls new versions when you choose.
The catch: these skills are written for agents that run without a person at the keyboard, and it shows in the commands. The gcloud skill tells the agent to add --quiet to every command so gcloud never stops at a confirmation prompt, and 38 SKILL.md files use the flag. In cloud-run-basics that means enabling APIs, granting an IAM role and deploying a public service with --allow-unauthenticated, each without the prompt gcloud would normally show. The same gcloud skill says IAM changes, API enabling and deletes need explicit approval, so the guard lives in instructions the model may or may not follow. Your agent's own permission settings, a project with limited roles and a billing budget are the real protection.
There is a smaller point about data. 166 of the skills tell the agent to tag every gcloud command and API request with an attribution string naming the skill. The text says it carries no user data and that the agent should drop it if you ask, but it is usage tracking for Google, and it is on unless you say otherwise.
Our take: compared with Anthropic's skills repo, this is narrower and more operational, a runbook library for one cloud rather than a set of general abilities. Install the handful that match the services you run, not all 195.
Where it earns its place
A backend developer at a 20-person startup on Google Cloud
Have Claude Code deploy a service to Cloud Run without guessing flags
Install cloud-run-basics and the gcloud skill, run the agent with an account that holds only the Cloud Run roles the skill lists, and keep shell approval on, since the skill's deploy example makes the service public and skips prompts.
An SRE team running GKE clusters with TPU workloads
Diagnose stuck TPU slices and unresponsive nodes faster
The troubleshooting skills give the agent Google's own checks for cases such as VMs stuck in REPAIRING or leaked node-pool capacity. They mostly read state, which makes them safer to run with less supervision than the deploy skills.
A mobile developer monetising an Android app
Add banner, interstitial and rewarded ads and validate the integration
The Google Mobile Ads SDK skills walk the agent through installation and each ad format, and a validation skill checks the result. Free; ad revenue and policy review are Google's usual terms.
Before you commit
- Setup
- npx skills add google/skills, then choose skills, target agents and project or global scope. In Claude Code, claude plugin marketplace add google/skills and claude plugin install <plugin>@google-plugins. Most skills assume gcloud is installed and authenticated.
- Integrations
- Any agent that reads SKILL.md through the skills CLI, Antigravity, Gemini CLI, Claude Code and Codex. The 17 plugins pull MCP servers and skills from GoogleCloudPlatform repos for AlloyDB, BigQuery, Bigtable, Cloud SQL, Dataproc, Firestore, Looker, Spanner and others.
- Data and privacy
- Skills are text and scripts run on your machine with your Google credentials. 166 skills ask the agent to add an attribution tag to gcloud commands and API requests; the skill text says it holds only the skill name and version and is dropped on request.
- Cost at scale
- Free to install. The cost is what the agent provisions: Cloud Run, GKE, BigQuery and the rest bill normally, and the gcloud skill's ban on enabling APIs is an instruction, not a control, so set a budget alert.
- Limits
- No releases or changelog; updates come through npx skills update. Some skills contradict the gcloud skill's approval rules. Workspace, Maps, Android and Firestore skills are in other repos.
What’s good
- Official, versioned skills with evals and human review behind each change
- Deep GKE, BigQuery, IAM and security coverage
- Plugin marketplace for Claude Code and Codex with bundled MCP servers
- Apache-2.0, so skills can be forked and adapted
What’s not
- Commands pass --quiet, skipping gcloud's confirmation prompts
- Usage attribution tags on by default in 166 skills
- Mostly Google Cloud; Ads and Analytics coverage is thin
- No tagged releases
Best for
Engineers who let coding agents work in Google Cloud projects and want Google's own procedures loaded instead of the model's memory of gcloud.

Google Agent Skills: common questions
- Is Google Agent Skills worth it?

- How much does Google Agent Skills cost?
- Free under Apache-2.0. The Google Cloud, Ads and Analytics services the skills drive are billed as usual.
- What are the downsides of Google Agent Skills?
- Commands pass --quiet, skipping gcloud's confirmation prompts; usage attribution tags on by default in 166 skills; mostly Google Cloud; Ads and Analytics coverage is thin; no tagged releases.
