The CRUXCODE.DEV developer experience
Set up your editor once.
Teach your AI agent your standards.
CRUXIDE installs the VS Code extensions for the stack you actually work in, and writes engineering rules your AI coding agent reads. Nothing installs until you confirm.
ext install CRUXCODE.cruxidePaste into Quick Open (Ctrl+P). Free and open source, MIT licensed.
Pick your stack. I’ll show you the whole plan before anything installs.
Drag to spin
The problem
The same lost afternoon, every new project.
You install the same extensions from memory, half of them the wrong ones. Then you open an AI assistant and re-explain your architecture, testing rules and security expectations in every prompt.
Extension packs make it worse: they install everything for everyone, so an Angular developer ends up carrying Flutter tooling. CRUXIDE fixes the setup problem and the prompting problem together.
One catalog • Every agent
What’s in the catalogue
These are the totals with every track selected. Tracks share tools, so extensions are counted once however many tracks use them.
Setup & Tracks
Every track, and exactly what it installs
This mirrors the real setup panel, with the same tracks, counts and dialog. Open any track to see its extensions, skills and rule packs. It’s a simulation: nothing here touches your machine.
Tracks
All tracks start selected. Uncheck anything this profile does not need.
26 tracks • 87 unique extension entries • 124 mapped skills and rules

Deselecting a track later never uninstalls tools you may still be using.
How it works
From install to a better-briefed agent
Steps 1 to 6 configure the editor. Steps 7 to 9 configure how your AI agent works on the project.
Your editor
Once per profile.
- Install CRUXIDEFrom the Marketplace or Open VSX.
- Setup opens on first runNothing has been installed yet.
- Review the tracksAll start selected. Uncheck what this profile doesn’t need.
- Confirm the planIn VS Code’s own dialog. This is the point of consent.
- Missing tools installAnything you already have is skipped and never downgraded.
- The CRUXIDE experience appliesTheme, icon theme, window title and font settings. If a setting can’t be written, it tells you which one.
Your AI agent
Per project, whenever you need it.
- Open the Skills ManagerFrom Home, the Activity Bar or the Command Palette.
- Choose what your agent learnsSkills, rules, scope, rule mode and target agent, then install the guidance.
- Invoke /crux-conductorWhen a task needs several skills coordinated.
CRUX Skills
The Skills Manager, and exactly what it writes
This mirrors CRUX Skills in VS Code, step for step. It starts from the tracks you picked above, so you see precisely which skills, rule packs and files your choices produce. Change the scope or agents and the file list updates.
Installation target
Where the files go, which agents read them, and how strictly rules apply.
Agents
Your agent is told: Recommendations only. Explain material deviations, but do not block work.

Review & Install
Everything below updates as you change tracks, scope, agents or selections.
- No application runtime dependencies.
- No package.json, node_modules, Git hooks, or shared .gitignore changes.
- External/provider skills are documented and require your separate review.
- Existing skill files are backed up before replacement.
Extensions from your selected tracks
Setup installs these into your active VS Code profile when you apply your tracks, on Windows. Scope doesn’t affect extensions; it only decides where skill files go.

Orchestration
/crux-conductor coordinates, it doesn’t take over
A skill you invoke explicitly inside a supported AI agent, when a task needs several skills working together.
What it does
- Reads your prompt and your project context, and picks the minimum set of installed skills that fits.
- Orders them and resolves conflicts between them.
- Coordinates handoffs and checks for one coherent result.
What it isn’t
- Not an AI model and not a replacement for Codex, Claude Code, Copilot, Cursor or Gemini.
- Not a background agent or an autonomous runtime.
- Never activates itself. It runs only when you invoke it.
Built for trust
What installs, and what never does
Only after you confirm
- VS Code extensions for the tracks you selected, into the active profile. Tools built for another platform are skipped.
- Markdown skill and rule files, in the scope you chose.
- CRUXIDE’s theme, icon theme, editor and terminal font settings, and window title.
Font settings only: a Marketplace install doesn’t install the Roboto Mono font file. If it’s missing, the editor falls back to the next font in its stack.
Never
- Language runtimes, compilers or SDKs: Node.js, Python, JDK, .NET, Go, Rust, Flutter, Xcode and the rest.
- Database servers, emulators, application dependencies or ORM packages.
- Git hooks or provider credentials.
- Changes to
package.jsonor any project manifest.
Privacy
- No analytics, no telemetry, no crash reporting.
- It doesn’t read or transmit your workspace contents, filenames, credentials or personal information.
- The extension host makes no background network requests.
Security
- Webviews load only local assets under a restrictive Content Security Policy.
- Every webview message is validated against a fixed allowlist.
- No workspace code execution and no child processes.
- Project writes respect VS Code Workspace Trust.
Platform scope
Works in the editor you already use
Visual Studio Code
Install from the VS Code Marketplace. The editor CRUXIDE is built and tested against.
Cursor, Windsurf, VSCodium, Gitpod
Install from Open VSX, straight from the extensions panel. Skills are guidance files your agent reads; CRUXIDE doesn’t drive the editor’s AI directly.
JetBrains and WebStorm
Not supported. It would need a separate IntelliJ Platform plugin.
Known limitations
Limitations, stated plainly
- CRUXIDE configures the active VS Code profile. An extension can’t create or switch profiles for you, so if you want it isolated, run Profiles: Create Profile, switch to it, then run setup. The Windows and macOS installers in the GitHub release create a dedicated profile for you.
- Skills and rules are guidance your AI agent reads. CRUXIDE doesn’t execute them and can’t force an agent to follow them.
- Uninstalling CRUXIDE leaves the extensions you confirmed, the settings it applied and your project files in place, so you decide what to remove.
