google-agents-cli-workflow

A development workflow for building, testing, debugging, deploying, and publishing software agents with Google’s Agent Development Kit, a framework for creating agents. It uses the agents-cli command-line tool and starts with a project scaffold.

In plain words
What is it for?
Use it when creating an agent, running it locally, debugging its code, testing it, deploying it to Google Cloud, or publishing it. It also covers checking required tool versions and following phase-specific guidance.
Why use it?
It provides an ordered process and project conventions for the agent-development lifecycle. This helps prevent missing setup, evaluation files, or deployment configuration.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

google-agents-cli-workflow scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Agent Development Workflow & Guidelines

agents-cli is a CLI and skills toolkit for building, evaluating, and deploying agents on Google Cloud. It works with any coding agent — Antigravity CLI, Claude Code, Codex, or others — and with the agent framework of your choice (the Agent Development Kit (ADK) by default). Install with uvx google-agents-cli setup.

Before writing agent code, make sure a scaffolded project exists (see Phase 2). Skipping scaffolding loses eval boilerplate, CI/CD config, and project conventions.

Requires: google-agents-cli = 1.4.2 If version is behind, run: uv tool install "google-agents-cli=1.4.2"

Check version: agents-cli info Install uv first if needed.

Session Continuity & Skill Cross-References

Re-read the relevant skill before each phase — not after you've already started and hit a problem. Context compaction may have dropped earlier skill content. If skills are not available, run uvx google-agents-cli setup to install them.

Phase Skill When to load
0 — Understand No skill needed — read .agents-cli-spec.md if present, else clarify goals with the user
1 — Study recipes /google-agents-cli-adk-code Load it during design — its references/samples.md topic index maps a need to the recipe that implements it. Yes, this early: the catalog lives there.
2 — Scaffold /google-agents-cli-scaffold Before creating or enhancing a project
3 — Build /google-agents-cli-adk-code Before writing agent code — API patterns, tools, callbacks, state
4 — Evaluate /google-agents-cli-eval Before running any eval — dataset schema, metrics, eval-fix loop
5 — Deploy /google-agents-cli-deploy Before deploying — target selection, troubleshooting 403/timeouts
6 — Publish /google-agents-cli-publish After deploying, if registering with Gemini Enterprise (optional)
7 — Observe /google-agents-cli-observability After deploying — traces, logging, monitoring setup

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
