Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/obra/superpowers-skills --skill scale-game
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads scale game automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

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 DimensionTest At ExtremesWhat It Reveals
Volume1 item vs 1B itemsAlgorithmic complexity limits
SpeedInstant vs 1 yearAsync requirements, caching needs
Users1 user vs 1B usersConcurrency issues, resource limits
DurationMilliseconds vs yearsMemory leaks, state growth
Failure rateNever fails vs always failsError 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

FAQ

What does the scale game skill do?

Test at extremes (1000x bigger/smaller, instant/year-long) to expose fundamental truths hidden at normal scales

How do I install scale game?

Run npx skills add https://github.com/obra/superpowers-skills --skill scale-game in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/scale-game/ (personal) or .claude/skills/scale-game/ (project).

Which AI agents can use scale game?

Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.

Is scale game safe to install?

No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
