Lagune helps your AI agent make a project more secure. You point it at your code, and the agent figures out what your system actually does, then guides you through the security work that matters for it.
- Lagune works with projects in any programming language and supports 72 agents ✨

Overview
Tip
- 🚪 Use
--portor-pto specify a custom port. ⏏️ PressCtrl+Cto stop.
npx -y lagune@latest init- 🃏 Lagune runs on Node.js under the hood, you use whatever language you want.
To update Lagune's own files and its commands to their latest versions, run:
npx -y lagune@latest updateTip
Your charter, the phase artifacts, and any custom specializations stay untouched.
When you clone or fork a project that already has Lagune, run pull to install its files from the manifest:
npx -y lagune@latest pullTip
💡 Think of it as the Lagune equivalent of npm i, pip install -r requirements.txt, and the like.
Once Lagune is set up in your project, your AI agent unlocks a set of slash commands:
Harden the work as you build it, guided by the charter, with no flow to follow:
| Command | What it does for you |
|---|---|
| /lagune | Enforces security along with your development, on any prompt, at any time |
- Pull in the on-demand specializations in real time while your agent works.
- Combine it with the /lagune.charter command to shape every build around your project's own security rules.
These five run in order. Each builds on the previous, so following the list top to bottom is all it takes:
| # | Command | What it does for you |
|---|---|---|
| 1 | /lagune.charter | Sets your project's security rules, proposed for you or shaped by what you say |
| 2 | /lagune.detect | Reads your code and maps what your system does and where the risks are |
| 3 | /lagune.plan | Turns what detect found into a defense plan, with a fix for each finding |
| 4 | /lagune.harden | Applies the plan's fixes to your code, safely and one at a time |
| 5 | /lagune.verify | Proves each applied fix holds and closes out the ones that do |
| Command | What it does |
|---|---|
| /lagune.specialize | Specializes Lagune in a new security sub-skill from articles, exploits, or topics |
| /lagune.prove | Turns each detected finding into a runnable proof for responsible disclosure |
Tip
Security is not a cost, it is an investment: what you put in upfront, you save many times over in the incidents you never have 🙋🏻♂️
Important
See the full documentation for usage examples and more.
You will need these tools installed on your system:
