Scale Game

Scale Game is a skill for Claude Code from huuanh20/awesome-ai-agent-skills. It costs 27 tokens per session (643 once invoked), scanned A, a copy of Scale Game, MIT.

A thinking method that checks whether an idea still works when key conditions become much smaller, larger, faster, slower, or longer-lasting.

In plain words
What is it for?
Evaluating volume, speed, number of users, duration, failure rates, and data size in software designs, workflows, and error handling.
Why use it?
Normal examples can hide limits and failure points. Testing extremes helps 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 12d 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, index needs
Speed Instant vs year-long Async requirements, caching needs, timeouts
Users 1 user vs 1B users Concurrency issues, resource limits, auth bottlenecks
Duration Milliseconds vs years Memory leaks, state growth, data rot
Failure rate Never fails vs always fails Error handling adequacy, retry logic
Data size 1 byte vs 1TB Storage strategy, streaming vs buffering

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, contracts) or expect them (chaos engineering, circuit breakers)

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 — cannot rely on process memory

Example 4: Single DB Write Path

Normal load: One writer, no contention At 10k concurrent writes: Deadlocks, lock contention, queue buildup Reveals: Need optimistic locking, write batching, or event sourcing

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.
