Vvvv Editor Extensions

Helps create vvvv gamma editor extensions — .HDE.vl file naming, Command node registration with keyboard shortcuts, SkiaWindow/SkiaWindowTopMost window types...

Security Scan

This is an instruction-only skill that documents how to create vvvv gamma editor extensions; its requirements and instructions are consistent with that purpose and it does not request extra credentials, installs, or system access.

Purpose & Capability

The name/description (vvvv editor extensions) matches the SKILL.md content: file naming, Command node usage, window types, docking, and API access for VL.Lang Session. Nothing in the metadata or instructions asks for unrelated capabilities.

Instruction Scope

SKILL.md is purely documentation and runtime guidance for building editor extensions. It does not instruct the agent to read arbitrary files, access environment variables, call external endpoints, or perform system administration actions beyond normal extension development guidance.

Install Mechanism

No install spec or code files are present; this is instruction-only, so nothing is downloaded or written to disk by the skill itself.

Credentials

The skill declares no required environment variables, credentials, or config paths. The documented APIs and NuGet references (VL.HDE, VL.Lang) are appropriate and expected for vvvv extension development.

Persistence & Privilege

always is false and model invocation is allowed (default). There is no attempt to modify other skills or persist credentials; no elevated or permanent privileges are requested.

Assessment

This skill is documentation for writing vvvv editor extensions and does not install or request credentials. It appears coherent and low-risk as-is. However: if you follow its guidance to create or enable .HDE.vl extensions, remember those extension files run inside the editor and can execute arbitrary logic against your project files — only use extensions from sources you trust and review the .HDE.vl contents before loading or distributing them. The skill itself will not fetch or run code, but any code you generate or enable following it should be inspected.

Editor Extensions

Extensions are standard VL patches saved with a .HDE.vl suffix. They run automatically when open in the editor.

File Naming

Context	Required Name
Standalone extension	VL.MyExtension.HDE.vl
Extension-only NuGet	VL.MyExtension.HDE (package ID)
Mixed NuGet main doc	VL.MyPackage.vl
Mixed NuGet extension doc	VL.MyPackage.HDE.vl

Required NuGet References

• VL.HDE — provides Command node, window types, WindowFactory
• VL.Lang — provides API nodes under the Session category

Command Node

Registers a command in the editor menu:

Pin	Purpose
Label	Menu text
Visible	Show/hide the command
Shortcut	Keyboard binding
Output	Triggers (bang) on activation

Multiple Command nodes can live in one .HDE.vl document.

Warning: A runtime error in one command may affect all others in the same document.

Window Types

Type	Behavior
SkiaWindow	Slimmed-down Skia renderer window
SkiaWindowTopMost	Always-on-top, no focus steal

Docking

Wrap window with WindowFactory node. Connect WindowContext and Window pins.

Template: VL.HDE/Template.HDE.vl

API Access

Access hovered/selected nodes, read/write pins via VL.Lang Session category nodes. Browse available API in the HelpBrowser's API section.

Developer Shortcuts

• Shift+F9 — restarts all extensions simultaneously

Limitations

• Settings panel integration is not yet possible
• Extensions only run in the editor, not in exported applications
