Full Stack HQ

Opinionated AI engineering workflow and configuration for Google Antigravity and Claude Code.

Full Stack HQ packages global rules, specialist agents, reusable skills, and workflow files for controlled, planned, and reviewable engineering work. It is a configuration and documentation repository—not a SaaS product, generic AI platform, agent runtime, or application framework.

The permission model is implemented as instructions in GEMINI.md and CLAUDE.md. It is not a runtime sandbox or hard enforcement layer; behavior still depends on the host agent applying the installed instructions.

What is included

Component	Count	Role
Global rules	2	Host-specific instructions in GEMINI.md and CLAUDE.md
Agents	10	Specialist role definitions
Skills	28	Reusable domain guidance modules
Workflows	10	Antigravity workflow files

The maintained integration surfaces are Google Antigravity and Claude Code. The default installers install the rules, agents, and skills for both; workflow files are installed for Antigravity.

Workflow model

The included rules describe a permission-aware engineering workflow:

1. Plan the work and identify the relevant specialist.
2. Present the scope, assumptions, and proposed changes.
3. Wait for explicit approval before executing the approved slice.
4. Report what changed, what was verified, and what remains.

The configured approval phrases are:

PLAN APPROVED
IMPLEMENTATION APPROVED
PROCEED
DO IT

These phrases are part of the installed prompt/configuration guidance. They do not intercept shell commands, enforce filesystem permissions, or guarantee host-agent behavior.

Installation

The installers copy files from the cloned repository, so run them from a local checkout.

macOS / Linux

git clone https://github.com/sabahattink/antigravity-fullstack-hq.git
cd antigravity-fullstack-hq
chmod +x install.sh
./install.sh

Available options:

Option	Effect
--only-antigravity	Install only the Antigravity files
--only-claude	Install only the Claude Code files
--force	Skip the prompt for existing global rules files

Windows (PowerShell)

git clone https://github.com/sabahattink/antigravity-fullstack-hq.git
Set-Location antigravity-fullstack-hq
.\install.ps1

Available switches:

Switch	Effect
-OnlyAntigravity	Install only the Antigravity files
-OnlyClaude	Install only the Claude Code files
-Force	Skip the prompt for existing global rules files

The scripts target the following locations:

Antigravity
  ~/.gemini/GEMINI.md
  ~/.gemini/antigravity/agents/
  ~/.gemini/antigravity/skills/
  ~/.gemini/antigravity/workflows/

Claude Code
  ~/.claude/CLAUDE.md
  ~/.claude/agents/
  ~/.claude/skills/

Restart the host application after installation so it reloads the global files.

The current scripts prompt only for existing GEMINI.md or CLAUDE.md; same-named agent, skill, and workflow files are copied into their target directories.

Technology defaults

The included guidance is opinionated around common full-stack engineering work:

• Web: Next.js, React, TypeScript, and Tailwind CSS
• Services and data: NestJS, Node.js, PostgreSQL, and Prisma
• Delivery and verification: Vitest, Jest, Playwright, Docker, and GitHub Actions

These are documentation defaults and examples, not dependencies installed by this repository. Edit the installed ~/.claude/CLAUDE.md or ~/.gemini/GEMINI.md when a project uses different conventions.

Agents

Agent	Focus
frontend-specialist	React, Next.js, Tailwind, and UI/UX
backend-specialist	NestJS, APIs, queues, and Redis
database-specialist	Prisma, PostgreSQL, and migrations
architect	System design, ADRs, and trade-offs
code-reviewer	Quality, patterns, and security
test-engineer	Vitest, Jest, and Playwright
security-auditor	Auth, OWASP, and input validation
devops-engineer	Docker, CI/CD, and deployment
performance-optimizer	Bundles, queries, and rendering
documentation-writer	Technical writing, READMEs, and ADRs

Skills

The 28 skills are grouped by purpose:

Area	Skills
Frontend	react-best-practices, typescript-patterns, tailwind-patterns, frontend-design, web-design-guidelines, nextjs-app-router
Backend	nestjs-patterns, backend-dev-guidelines, software-architecture, api-design-patterns, prisma-workflow
Testing	test-driven-development, systematic-debugging, webapp-testing
DevOps	docker-patterns, github-actions, deployment-guide
Auth and security	auth-patterns, security-checklist
Documents	docx-official, pdf-official, pptx-official, xlsx-official
Meta	brainstorming, skill-creator, code-review-patterns, git-workflow, prompt-engineering

Workflows

The 10 workflow files are installed under ~/.gemini/antigravity/workflows/:

Command	Use
/plan	Break work into phases before implementation
/brainstorm	Explore options and trade-offs
/debug	Work through a systematic root-cause analysis
/create	Implement an approved plan
/enhance	Improve existing code quality
/test	Generate or fix tests
/status	Record progress, blockers, and next steps
/preview	Review quality, security, and commit readiness
/orchestrate	Coordinate specialist workstreams
/ui-ux-pro-max	Run a structured UI/UX review

Claude Code receives CLAUDE.md, the agents, and the skills from the installers; it does not receive these workflow files.
