TL;DR

AI coding agents can take a non-technical founder from zero to a working MVP. Use Claude Code, Gemini CLI, and Rovo Dev CLI for planning, diffs, refactors, tests, and releases. Treat agents like a junior engineer who types at 200 wpm and never gets bored. Keep humans in the loop for product judgment, architecture, and security.

Why this is possible now

Agentic CLIs are real: Claude Code, Gemini CLI, and Rovo Dev CLI run in your terminal, read your repo, call tools, and iterate with you in natural language. Anthropic Google AI for Developers Atlassian Support
The workflow fits founders: describe the outcome, let the agent propose a plan, run safe edits, generate tests, and ship small. This is the “vibe coding” shift that moved from novelty to mainstream coverage this summer. The Verge Business Insider

What “vibe coding” actually means

You guide by intent rather than by keystroke. You describe what you want, accept or reject proposals, and keep a tight feedback loop with tests and previews. It is powerful for prototypes and first versions. It is not a substitute for careful engineering on core systems. Business Insider

Your starter toolchain

1) Claude Code

Install

  bashCopyEditnpm install -g @anthropic-ai/claude-code
  claude

Use cases: understand an unfamiliar repo, create feature branches, write or fix tests, draft PRs, wire MCP servers for outside data.
Docs to trust: overview, setup, CLI reference, common workflows. Anthropic+3Anthropic+3Anthropic+3

2) Gemini CLI

Install

  bashCopyEditnpm install -g @google/gemini-cli
  gemini

or run directly:

  bashCopyEditnpx https://github.com/google-gemini/gemini-cli

Use cases: fast multi-modal ideation, long-context repo edits, GitHub Actions integration.
Docs and repo: quickstart for API fundamentals, official CLI repo, deployment notes. Google AI for Developers GitHub+1

3) Rovo Dev CLI

Install and run

  bashCopyEdit# Install Atlassian CLI, then:
  acli rovodev auth login
  acli rovodev run

Use cases: code tasks plus tight Jira and Confluence integration, memory files, MCP connections.
Docs: quickstart, advanced features, product announcement. Atlassian Support+2Atlassian Support+2 Atlassian

The founder workflow: shipping loop that actually works

State the goal: “Add email signup with double opt-in and tests. Next.js project. Use Resend.”
Plan first: ask the agent for a step list with file-level changes and test strategy.
Generate a diff: review the patch, request smaller chunks, ask for comments.
Run and test: have the agent write unit tests, then you run them locally.
Iterate: keep requests small: one component, one route, one test suite.
Commit and PR: ask the agent for the PR title and body.
Deploy: let the agent produce a release checklist and scripts.

Claude Code and Gemini CLI both support interactive sessions and repo-wide edits from the terminal. Rovo Dev CLI adds “speak the Jira ticket, get the branch and PR” flow. Anthropic+1 Atlassian Support

Guardrails you must set on day one

Sandbox first: never point an agent at your only repo. Fork or branch.
Least privilege: limit tool access and allowlists. Claude Code supports tool allowlists. Rovo uses memory and MCP configs you control. Anthropic Atlassian Support
Secrets handling: keep API keys out of chat. Use env files or secret managers.
Prompt-injection awareness: treat any untrusted file or README as hostile input.
Track known issues: Gemini CLI recently patched a flaw that allowed stealthy command execution and data exfiltration. Update promptly. BleepingComputer CSO Online

What to build as a first milestone

Pick one useful, narrow slice that proves value:

A feature-complete landing page with email capture and analytics.
A data importer with validation and a tiny admin UI.
A scheduled job that pulls a public dataset and generates a weekly report.

Ship in 7 to 10 days. Keep scope under 1,000 lines of net new code. Ask the agent to keep diffs under 150 lines per commit and to auto-generate tests and docs.

When you still bring in an engineer

You are touching payments, PII, or regulated workloads.
You need custom infrastructure, unusual performance constraints, or complex data modeling.
You must harden for scale or security audits.

Even then, the agent trio remains your “force multiplier” for scaffolding, tests, scaffolding migrations, and docs.

Common objections

“Isn’t vibe coding sloppy?”
It can be. The fix is to work in short loops, demand tests, and review diffs like a hawk. Leaders across the industry say it is great for prototyping and iteration. Keep humans in charge of architecture. Business Insider

“Will I get locked into one vendor?”
Use Git, standard frameworks, and simple CLIs. Claude Code and Rovo both speak MCP for tool access. Gemini CLI is open source and runs in your terminal. Switching remains practical. Anthropic Atlassian Support GitHub

“Do I need to ‘learn to code’ first?”
You need product sense and the ability to read diffs and tests. Think editor in chief, not typist. The tools are designed to translate intent into code, while you enforce quality. Anthropic
