Scale Game

Scale Game is a skill for Claude Code from VoDaiLocz/kilo-kit-mcp. It costs 27 tokens per session (529 once invoked), scanned A, a copy of Scale Game, Apache-2.0.

A design-checking method that tests an idea at extremely small and large scales, such as one item versus one billion. It also compares very short and very long times, user counts, and failure rates.

In plain words
What is it for?
Use it to examine algorithms, services, error handling, caching, asynchronous work, and long-running processes before they meet unusual production conditions.
Why use it?
Normal examples can hide limits such as slow processing, memory leaks, concurrency problems, or overwhelmed error handling. Extreme cases reveal where an approach breaks and what remains sound.

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

Scale Game 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 6d 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.

Scale Game

Overview

Test your approach at extreme scales to find what breaks and what surprisingly survives.

Core principle: Extremes expose fundamental truths hidden at normal scales.

Quick Reference

Scale Dimension Test At Extremes What It Reveals
Volume 1 item vs 1B items Algorithmic complexity limits
Speed Instant vs 1 year Async requirements, caching needs
Users 1 user vs 1B users Concurrency issues, resource limits
Duration Milliseconds vs years Memory leaks, state growth
Failure rate Never fails vs always fails Error handling adequacy

Process

  1. Pick dimension - What could vary extremely?
  2. Test minimum - What if this was 1000x smaller/faster/fewer?
  3. Test maximum - What if this was 1000x bigger/slower/more?
  4. Note what breaks - Where do limits appear?
  5. Note what survives - What's fundamentally sound?

Examples

Example 1: Error Handling

Normal scale: "Handle errors when they occur" works fine At 1B scale: Error volume overwhelms logging, crashes system Reveals: Need to make errors impossible (type systems) or expect them (chaos engineering)

Example 2: Synchronous APIs

Normal scale: Direct function calls work At global scale: Network latency makes synchronous calls unusable Reveals: Async/messaging becomes survival requirement, not optimization

Example 3: In-Memory State

Normal duration: Works for hours/days At years: Memory grows unbounded, eventual crash Reveals: Need persistence or periodic cleanup, can't rely on memory

Red Flags You Need This

  • "It works in dev" (but will it work in production?)
  • No idea where limits are
  • "Should scale fine" (without testing)
  • Surprised by production behavior

Remember

  • Extremes reveal fundamentals
  • What works at one scale fails at another
  • Test both directions (bigger AND smaller)
  • Use insights to validate architecture early

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.
