AI coding tools setup (Antigravity · Cursor · GitHub Copilot · ChatGPT / Codex)

How to sign in, connect GitHub, and work with repos like DeukPack. UIs change—check each product’s official docs.

Common: what “connect to GitHub” means

Piece What you do
Repo on disk git clone the repository
Push / PR Git authenticates with HTTPS (PAT) or SSH keys
AI apps Separate login: Google / Cursor / GitHub / OpenAI — often the same GitHub account helps for PR/issue integrations

Never commit tokens or API keys.

1. Google Antigravity

Agent-oriented IDE (Gemini). GitHub is usually via Git + GitHub auth, not a special “Copilot inside Antigravity” (varies by version).

  1. Install from Antigravity.
  2. Sign in with your Google account.
  3. Open the cloned DeukPack folder (or git clone first).
  4. Git ↔ GitHub: HTTPS with a PAT, or SSH key added to GitHub.
  5. MCP: optional extras from the product’s MCP store. For DeukPack, run npx deukpack / node scripts/build_deukpack.js in the terminal.

Copilot: Antigravity is Gemini-centric; use VS Code + Copilot if you need GitHub Copilot specifically.

2. Cursor

VS Code–style editor with built-in AI.

  1. Install from cursor.com.
  2. Sign in to Cursor.
  3. Optional: GitHub in Settings → Account / Integrations (wording varies).
  4. Use .cursor/rules/ for project constraints (this repo may already include rules).
  5. Shortcuts: see in-app Keyboard Shortcuts.

3. GitHub Copilot

  1. Copilot license on your GitHub account — GitHub Copilot.
  2. Install GitHub Copilot (+ Chat) in VS Code or the JetBrains plugin.
  3. Sign in to GitHub from the editor.
  4. Open the repo folder; Copilot uses workspace context.

4. ChatGPT · OpenAI Codex

  1. chatgpt.com — sign in; features depend on plan.
  2. Codex CLI / IDE integrations — follow OpenAI and in-product guides; store API keys only in env/secrets.
  3. GitHub is not auto-linked; use upload, copy-paste, or a separate official integration when available.
  1. One clone, open in your preferred tool.
  2. Run codegen deterministically: npm ci, npm run build, npx deukpack … or pipeline scripts — see Quick start, Pipeline guide.
  3. Let AI help with drafts and refactors; keep wire format and multi-language contracts on the DeukPack pipeline — AI / agent pipeline.
