→ fluid not rigid
→ iterative not waterfall
→ easy not complex
→ built for brownfield not just greenfield
→ scalable from personal projects to enterprises

[!TIP] New workflow now available! We've rebuilt ProjectX with a new artifact-guided workflow.

Quick Start

Requires Node.js 20.19.0 or higher.

Install ProjectX globally:

npm install -g @tech-accelerator/projectx@latest

Then navigate to your project directory and initialize:

cd your-project
projectx init

Now tell your AI: /prox:propose <what-you-want-to-build>

If you want the expanded workflow (/prox:new, /prox:continue, /prox:ff, /prox:verify, /prox:bulk-archive, /prox:onboard), select it with projectx config profile and apply with projectx update.

Also works with pnpm, yarn, bun, and nix. See installation options.

Community schemas

Third-party schema bundles distributed via standalone repositories — these provide opinionated workflows that integrate ProjectX with other tools, similar to how github/spec-kit's community extension catalog handles tool integrations.

Why ProjectX?

AI coding assistants are powerful but unpredictable when requirements live only in chat history. ProjectX adds a lightweight spec layer so you agree on what to build before any code is written.

• Agree before you build — human and AI align on specs before code gets written
• Stay organized — each change gets its own folder with proposal, specs, design, and tasks
• Work fluidly — update any artifact anytime, no rigid phase gates
• Use your tools — works with 20+ AI assistants via slash commands

Updating ProjectX

Upgrade the package

npm install -g @tech-accelerator/projectx@latest

Refresh agent instructions

Run this inside each project to regenerate AI guidance and ensure the latest slash commands are active:

projectx update

Usage Notes

Model selection: ProjectX works best with high-reasoning models. We recommend Codex 5.5 and Opus 4.7 for both planning and implementation.

Context hygiene: ProjectX benefits from a clean context window. Clear your context before starting implementation and maintain good context hygiene throughout your session.

Contributing

Small fixes — Bug fixes, typo corrections, and minor improvements can be submitted directly as PRs.

Larger changes — For new features, significant refactors, or architectural changes, please submit an ProjectX change proposal first so we can align on intent and goals before implementation begins.

When writing proposals, keep the ProjectX philosophy in mind: we serve a wide variety of users across different coding agents, models, and use cases. Changes should work well for everyone.

AI-generated code is welcome — as long as it's been tested and verified. PRs containing AI-generated code should mention the coding agent and model used (e.g., "Generated with Claude Code using claude-opus-4-5-20251101").

Development

• Install dependencies: pnpm install
• Build: pnpm run build
• Test: pnpm test
• Develop CLI locally: pnpm run dev or pnpm run dev:cli
• Conventional commits (one-line): type(scope): subject

ProjectX collects anonymous usage stats.

We collect only command names and version to understand usage patterns. No arguments, paths, content, or PII. Automatically disabled in CI.
