Forge: A Claude-based IDE with automated verification and project DNA

Forge is a Claude-based IDE built on VS Code by a single developer over two weeks using Claude Code. Unlike Cursor and Copilot, Forge's AI agent doesn't just write code and hand you diffs - it runs automated verification before you see anything.

Automated verification system

The agent runs the type checker, executes your tests, checks coverage, and validates imports automatically. If verification fails, the agent enters a self-healing loop where it reads the error, fixes the code, and re-runs verification for up to 3 attempts. By the time you review the code, it already works.

Project DNA and context retention

Forge scans your codebase to build a Project DNA that includes:

• Tech stack
• File structure
• Code patterns
• Naming conventions
• Git hotspots
• Tech debt

This DNA is included in every request so the agent follows your patterns without being told. Every architectural decision you discuss gets captured in a Decision Journal, allowing the agent to build compounding context that doesn't reset.

Technical implementation

Built on VS Code, Forge works with all your existing extensions. It's Claude-only and requires you to bring your own API key. The tool is still under development but available for testing.
