What it does
Game Balance Economy is an agent skill from hashgraph-online/awesome-codex-plugins. Balance game difficulty, resources, rewards, probability, progression, economies, and dominant strategies. Use when tuning combat, loot, upgrades, scoring, level curves, AI difficulty, risk-reward choices, or any system where numbers shape player decisions.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `references/core/guide.md`, `scripts/expected_value.py` and `workflows/tuning-pass.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.
It sits in Game Development, covering Game design. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.
When your agent uses it
- Risk-reward choices
- Any system where numbers shape player decisions
Example prompts
- “/game-balance-economy”
Requirements
- Python 3
- Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Define the target experience: tense, generous, punishing, expressive, strategic, chaotic, readable, or mastery-driven.
- Map resources, sinks, sources, rewards, costs, probabilities, time, and failure penalties.
- Find dominant strategies, dead choices, runaway feedback, grind, scarcity collapse, and opaque randomness.
- Use expected value and simulation where useful, but validate with playtests.
- Produce a tuning table with ranges, defaults, rationale, and telemetry.
What it can do on your machine
Read from SKILL.md and the folder at commit d95c24b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Codex, Claude Code, and other Agent Skills-compatible clients.
From compatibility in the SKILL.md frontmatter.
Context cost
Game Balance Economy loads about 618 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 233 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Game Balance Economy
Use this skill when a game system needs numerical tuning. Balance is not just fairness; it is the shape of player decisions over time. A good balance pass names the intended experience before changing numbers.
Source Traceability
Primary source: The Art of Game Design: A Book of Lenses, Third Edition by Jesse Schell, especially chapters 12-13 on chance, expected value, fairness, challenge, meaningful choices, rewards, punishment, and economies. The workflow is transformed and paraphrased.
Supporting sources include MDA for reasoning from mechanics to dynamics and accessibility guidance for difficulty options that preserve player agency.
Workflow
- Define the target experience: tense, generous, punishing, expressive, strategic, chaotic, readable, or mastery-driven.
- Map resources, sinks, sources, rewards, costs, probabilities, time, and failure penalties.
- Find dominant strategies, dead choices, runaway feedback, grind, scarcity collapse, and opaque randomness.
- Use expected value and simulation where useful, but validate with playtests.
- Produce a tuning table with ranges, defaults, rationale, and telemetry.
Required Output
Balance Intent: what the numbers should make players feel and do.Economy Map: sources, sinks, currencies, rewards, gates, and conversion rates.Tuning Table: parameters, default values, safe ranges, and intended effects.Risk Review: dominant strategies, exploits, fairness issues, and accessibility concerns.Validation Plan: spreadsheet checks, script checks, playtest tasks, and telemetry.
Helper Script
Use scripts/expected_value.py for quick expected value checks:
python3 path/to/game-balance-economy/scripts/expected_value.py --outcome 0:0.5 --outcome 10:0.5Local References
