Product Update: Introducing Lun

[sundanc]

✨ The Unified Enforcement Gate for Your Engineering DNA

We are thrilled to announce Lun, a complete reimagining of how architectural rules are enforced in modern engineering teams.

We have taken everything you love about our CLI and MCP tools and fused them into a single high performance Rust binary. No more fragmented setups. No more re explanation tax. Just one tool to ensure your code matches your decisions every single time.

One Binary. Zero Dependencies.
Forget managing multiple packages or runtime environments. Lun is a standalone executable that works anywhere: macOS Silicon, Linux, WSL, and Windows.

Merged: MCP and CLI in One
The biggest breakthrough is unification. Previously, you had to configure terminal tools and MCP servers separately. Now, the lun binary handles both.

As a CLI, use it to clone, check status, push your knowledge base, or run lun validate to check code manually.
As an MCP server, simply run lun mcp to instantly give tools like Cursor, Claude, and Windsurf deep access to your architectural rules.

Automatic Enforcement
Lun is not just a search tool. It is a gatekeeper.

Git hooks: Run lun hook install to block non compliant commits before they happen.
CI and CD native: Integrate lun ci into your GitHub Actions to gate pull requests with the same rules your team uses locally.

Get Started in 30 Seconds
Installing Lun is now a single command experience:

curl -fsSL https://markdownlm.com/install/lun | sh

Once installed, authenticate and you are ready to go:

lun configure
lun clone

Why Lun
Lun represents the pivot point, the single source of truth where your documentation meets your implementation. By moving to a native Rust core, we have achieved sub millisecond validation speeds, ensuring governance never feels like a speed bump.

The re explanation tax is officially dead.
