Zodex

zodex

zodex is a ChatGPT-native remote coding workspace.

It gives ChatGPT a real Sprite-backed Linux machine and a tiny MCP tool surface that GPT models already know how to use well:

• exec_command
• write_stdin
• apply_patch

ChatGPT can clone repos, inspect code, edit files, run tests, keep long-lived sessions alive, and commit locally. The operator decides how GitHub writes happen:

• PR-only publishing without direct shell write tokens
• one-off repo-scoped push approval from the Sprite
• remote operator-granted push windows
• timed YOLO mode for trusted sessions
• repo-scoped YOLO for selected repos
• no-TTL YOLO for intentionally trusted environments

The supported repository slug for this project is amxv/zodex.

Why it exists

ChatGPT coding works best when the model has familiar tools and a real machine. zodex gives it both:

1. a Sprite Linux workspace instead of a simulated sandbox
2. command/stdin/patch tools that fit GPT coding behavior
3. normal Git history and normal test commands
4. operator-controlled GitHub write autonomy

Sprites are a good fit for this because coding-agent work is bursty. You can run real remote work when ChatGPT is active instead of renting an always-on VPS for a full month and leaving it idle most of the time.

Write modes

Start safe, then open more autonomy when the session earns it.

Review-first PR

zodex-agent github publish-pr \
  --repo owner/repo \
  --title "Title" \
  --base main \
  --body "Summary and tests."

publish-pr bundles the current committed HEAD, sends it to the local publisher daemon, and lets that daemon push a generated branch and open a PR. The writer-app token stays inside zodex-prd instead of being exposed to the agent shell.

One-off push approval

zodex-agent github request-push --repo owner/repo
# then normal Git works
git push origin main
zodex-agent github revoke-push --repo owner/repo

The default active grant TTL is 30m. Change it with --ttl 2h, disable TTL enforcement with --no-ttl, and opt into refresh-token caching with --cache-refresh-token only when intended.

Operator-granted push

zodex github grant-push --sprite dev-sprite --repo owner/repo
git push origin main
zodex github revoke-push --sprite dev-sprite --repo owner/repo

Use this when the human operator should open the write window from their own machine.

YOLO mode

zodex github mode yolo --sprite dev-sprite
zodex github mode yolo --sprite dev-sprite --ttl 4h
zodex github mode yolo --sprite dev-sprite --repo owner/repo
zodex github mode yolo --sprite dev-sprite --no-ttl
zodex github mode status --sprite dev-sprite
zodex github mode default --sprite dev-sprite

mode yolo defaults to a 2h TTL and all installed repositories. Passing --repo changes the scope to a repo allowlist; repeated repo-scoped YOLO commands merge with active repo grants instead of replacing them, and each repo keeps its own TTL. Passing --no-ttl makes the new window indefinite until the operator disables it. mode default removes only YOLO state and leaves explicit push grants alone.

Quick setup shape

See the Quickstart for the no-clone installer path. The setup flow is:

1. install the local zodex operator CLI
2. install and authenticate the Sprite CLI
3. create and select a Sprite
4. make the Sprite URL public for ChatGPT MCP access
5. create the reader and writer GitHub Apps
6. run zodex sprite setup
7. connect ChatGPT to the /mcp?key=... URL

Create two GitHub Apps:

• reader app: Contents: Read-only
• writer app: Contents: Read & write, Pull requests: Read & write, Device Flow enabled, user access token expiration enabled

Install zodex on the Sprite:

zodex sprite setup \
  --sprite zodex-dev \
  --repo owner/repo \
  --reader-app-id  \
  --reader-pem /absolute/path/to/reader.pem \
  --publisher-app-id  \
  --publisher-pem /absolute/path/to/writer.pem \
  --default-base main \
  --url-auth sprite

Connect ChatGPT to:

https:///mcp?key=

Documentation site

This repository includes an Astro documentation site for zodex. It covers ChatGPT setup, Sprite runtime architecture, GitHub App access, write modes, proxy and MCP front door, direct HTTP API, command reference, troubleshooting, and docs maintenance.

Run it locally with:

bun install
bun run dev

Validate the docs site with:

bun run check
bun run build

Deploy the docs worker with:

bun run deploy:docs

Production routing keeps zodex.ashray.xyz on the existing Cloudflare proxy worker. That worker forwards /mcp, /mcp/*, and /health to the live Sprite and sends all other paths to the zodex-docs worker origin.

The Astro docs content lives in src/content/docs, with site-wide navigation and metadata in src/data/docs.ts.
