morphbox: Instructions file for Claude Code

CLAUDE.md

morphbox CLAUDE.md is an instructions file for Claude Code from Instant-Unicorn/morphbox. It costs 989 tokens per session, scanned A, original, Apache-2.0.

Project instructions for MorphBox, a development tool with panels and a browser-based interface. They explain how to run its WebSocket and Vite development servers and how panels are structured and connected.

In plain words
What is it for?
Developing MorphBox panels, running the local environment, registering panels, connecting them to the backend, and preparing a package for publishing.
Why use it?
They give coding agents the project-specific rules needed to start the app and change panels without guessing. They also identify the required files and publishing script.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is Instant-Unicorn/morphbox's own configuration. It tells Claude Code how to work on morphbox itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything morphbox configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/kruger/projects/morphbox/web.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

morphbox CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Running Dev Servers

MorphBox requires TWO dev servers running simultaneously:

  1. WebSocket server: cd /home/kruger/projects/morphbox/web && MORPHBOX_HOST=100.96.36.2 npm run dev:ws (background)
  2. Vite dev server: cd /home/kruger/projects/morphbox/web && HOST=100.96.36.2 npm run dev (background)

Both must run on Tailscale IP (100.96.36.2), not localhost or external IPs. Use run_in_background: true when starting via Bash tool.

  • Always use web/prepare-package.sh for the publishing script, never make a new file

MorphBox Panel Development

When working with MorphBox panels, refer to the comprehensive guide at /home/kruger/projects/morphbox/MORPHBOX_PANEL_DEVELOPMENT_GUIDE.md which covers:

Key Panel Concepts

  • Panel Structure: All panels extend BasePanel.svelte and follow the PanelConfig and PanelState interfaces
  • Registry System: Panels are registered in web/src/lib/panels/registry.ts
  • WebSocket Communication: Panels communicate with backend via WebSocket context
  • File Locations:
    • Base panel: web/src/lib/panels/BasePanel.svelte
    • Panel types: web/src/lib/panels/types.ts
    • Panel registry: web/src/lib/panels/registry.ts
    • Custom loader: web/src/lib/panels/CustomPanelLoader.svelte

Creating New Panels

  1. Create component in web/src/lib/panels/YourPanel/YourPanel.svelte
  2. Register in registry.ts under initializeBuiltins()
  3. Export from web/src/lib/panels/index.ts

Built-in Panels

  • Sandbox Terminal (web/src/lib/Terminal.svelte with sandboxed={true}) - PTY terminal in container, safe for AI autonomy
  • Admin Terminal (web/src/lib/Terminal.svelte with sandboxed={false}) - PTY terminal on host, for system access
  • FileExplorer (web/src/lib/panels/FileExplorer/) - File navigation
  • CodeEditor (web/src/lib/panels/CodeEditor/) - Monaco editor integration
  • GitPanel (web/src/lib/panels/GitPanel/) - Git operations
  • WebBrowser (web/src/lib/panels/WebBrowser/) - Web preview
  • Settings (web/src/lib/panels/Settings/) - Configuration
  • TaskRunner (web/src/lib/panels/TaskRunner/) - Command execution
  • PromptQueue (web/src/lib/panels/PromptQueue/) - Claude prompt management

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
