balance-check

balance-check is a skill for Claude Code from CodePhobiia/claude-roblox-game-studio. It costs 34 tokens per session (779 once invoked), scanned A, original, MIT.

A game-balance review workflow for checking formulas and values such as damage, experience points, item drop rates, and difficulty scaling.

In plain words
What is it for?
Use it to inspect balance code, verify that tunable values live in configuration, document formulas, and simulate results across expected input ranges.
Why use it?
It helps reveal unclear formulas, hidden constants, unbounded growth, and unhandled edge cases before they distort gameplay.

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

balance-check 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 10d 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.

/balance-check — Game Balance Verification

Delegate to: game-designer (with systems-designer for formula review)

Steps

1. Identify What to Check

Ask: "Which system or formula are we checking?"

  • Default: All tunable systems (combat, progression, economy)

2. Locate Formulas

Search for relevant code:

grep -rn "damage\|XP\|drop\|spawn" src/ --include="*.lua" --include="*.luau"
grep -rn "config\|CONFIG\|Config" src/ReplicatedStorage/

3. Verify Each Formula

Checklist per formula:
  • Formula explicitly written (not buried in complex code)
  • Constants externalized to config module
  • Formula documented in relevant GDD
  • Formula result bounded (no infinite scaling without cap)
  • Edge cases handled (zero inputs, negative, max)

4. Simulate the Curve

For each formula, tabulate values across the expected input range:

Damage example:

Level | Base ATK | Weapon | Total Damage (avg)
------|----------|--------|--------------------
1     | 10       | 5      | 15
5     | 20       | 15     | 35
10    | 35       | 30     | 65
20    | 60       | 60     | 120
50    | 150      | 150    | 300
100   | 300      | 300    | 600

XP curve example:

Level | XP to next | Cumulative XP | Hours to reach (at 500 XP/hr)
------|------------|---------------|------------------------------
1 → 2 | 100        | 100           | 0.2
5 → 6 | 500        | 1500          | 3
10 → 11 | 2000     | 9500          | 19
20 → 21 | 10000    | 75000         | 150
50 → 51 | 100000   | 2000000       | 4000

5. Flag Balance Issues

  • Too steep: Grind feels unfair (target: fun, not punishing)
  • Too shallow: Player outgrows content too fast
  • Discontinuities: Sudden difficulty spikes
  • Unbounded: Values that can grow infinitely without cap
  • Undefined edges: What happens at max level / zero input?

6. Recommend Adjustments

For each issue, propose concrete changes:

Issue: XP curve at level 50 requires 4000 hours
Recommendation: Cap XP requirement at 50000 per level (reduces to 100 hours)
Impact: Whale players won't grind forever; retention curve healthier

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.

balance-check is a skill published in the GitHub repository CodePhobiia/claude-roblox-game-studio (9 stars, last pushed 4mo ago), licensed MIT. It adds 34 tokens to every session and 779 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
