apps

apps is a skill for Claude Code from jerpint/woltspace. It costs 29 tokens per session (1,983 once invoked), scanned A, original, MIT.

An isolated workspace for building, running, and managing apps, scripts, and experiments. An app is a project with its own server and dependencies that can be shared.

In plain words
What is it for?
Use it to create a self-contained app, service, tool, or experiment that needs a backend, its own dependencies, or public access.
Why use it?
It separates larger or shareable projects from a lightweight private site and gives them the files and setup they need to run independently.

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

apps scanned grade A with 1 finding 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 28d 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.

Apps — Isolated Workspaces

Apps are things you ship — apps, tools, services. They live at wolts/apps/{name}/ and are served at /app/{name}/. Each app is self-contained with its own code, deps, and server.

Apps are an escalation from sites. Your site (wolt/site/) is your lightweight private workspace. An app is for when the work needs its own server, dependencies, or is meant to be shared. Always confirm with the user before creating one.

Sites vs Apps

Site (wolt/site/) App (wolts/apps/)
Purpose Your private workspace Something you ship
Visibility Private to the wolt owner Can be public
Complexity Static HTML/CSS/JS, lightweight Own server, deps, manifest
Created by Wolts, freely User opts in
Manifest None needed woltspace.json required
Example Personal digest, scratch mockups Workout tracker, shared tool

When to suggest an app: the user wants a backend, deps, sharing, or something that outgrows static HTML. Say: "This is getting complex — want me to set it up as an app?"

Creating an app

mkdir -p /workspace/wolts/apps/my-app
cd /workspace/wolts/apps/my-app
# ... set up your code

Then write woltspace.json — this is required for the platform to discover and serve the app:

{
  "name": "my-app",
  "description": "What this does",
  "stack": "node",
  "port": 4010,
  "install": "npm install",
  "start": "npm run dev --port $PORT --host 0.0.0.0",
  "keeper": "your-wolt-name",
  "public": false
}

Fields

Field Required Description
name yes Matches directory name, globally unique
keeper yes Your wolt name — who owns this
description no What the app does
stack no python, vite, node, or html
install no Install command
port yes Fixed port for this app. Permanent — survives restarts. Avoid 7777 and 3001.
start no Start command. Use $PORT — the platform expands it. Add --host 0.0.0.0 for network access. Null = can't start from lodge.
source no Origin URL if cloned
emoji no Display emoji (auto-assigned)
public no If true, the app is shared publicly when started. With a named tunnel: served at {name}.{domain} (e.g. corework.woltspace.com). Without: a random quick tunnel URL. Default: false.

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.
