What Scan Movers is

Scan Movers is a slash command published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.

Scan Movers gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.

How to install Scan Movers

Claude Code

Download scan-movers.md from the repository.
Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
Run it by typing / followed by its name.

Claude Cowork

Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
In Customize → Skills, click +, then upload the ZIP.
Run it from any task with / and the skill name.

2. Display Interface

class MoversDisplay {
    displayResults(results) {
        const output = `
╔════════════════════════════════════════════════════════════════╗
║                    MARKET MOVERS SCANNER                       ║

3. Real-Time Updates

class RealTimeScanner {
    constructor() {
        this.scanner = new MarketMoversScanner();
        this.display = new MoversDisplay();
        this.updateInterval = 30000; // 30 seconds
        this.isRunning = false;
    }

    async start(params) {
        this.isRunning = true;
        console.log('Starting real-time market scanner...');

        while (this.isRunning) {
            try {
                // Scan markets
                const results = await this.scanner.scanMarkets(params);

                // Clear console and display
…

4. Advanced Filtering

class ScannerFilters {
    applyFilters(asset, filters) {
        // Market cap filter
        if (filters.minMarketCap && asset.marketCap < filters.minMarketCap) {
            return false;
        }
        if (filters.maxMarketCap && asset.marketCap > filters.maxMarketCap) {
            return false;
        }

        // Volume filter
        if (filters.minVolume && asset.volume < filters.minVolume) {
            return false;
        }

        // Price filter
        if (filters.minPrice && asset.price < filters.minPrice) {
            return false;
…

Error Handling

try {
    const scanner = new RealTimeScanner();

    await scanner.start({
        markets: 'all',
        timeframe: '24h',
        categories: ['gainers', 'losers', 'volume', 'unusual'],
        limit: 20,
        filters: {
            minVolume: 1000000,
            excludeStablecoins: true
        },
        sortBy: 'percentage'
    });

    // Graceful shutdown
    process.on('SIGINT', () => {
        scanner.stop();
…

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
