Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.01411 |
| Opus 5 | $0.00030 | $0.00705 |
| Sonnet 5 | $0.00012 | $0.00282 |
| Haiku 4.5 | $0.00006 | $0.00141 |
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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Phase 1: Identify Balance Domain
Determine the balance domain from $ARGUMENTS:
- Combat → weapon/ability DPS, time-to-kill, damage type interactions
- Economy → resource faucets/sinks, acquisition rates, item pricing
- Progression → XP/power curves, dead zones, power spikes
- Loot → rarity distribution, pity timers, inventory pressure
- File path given → load that file directly and infer domain from content
If no argument, use question:
- "Which system should I check for balance?"
- Options:
[A] Combat balance/[B] Economy balance/[C] Progression balance/[D] Loot balance
Phase 2: Gather Context
Run these in parallel using Glob/Grep:
Glob pattern="assets/data/**/*.json" → find all data files
Glob pattern="assets/data/**/*.tres" → find Godot resource data files
Grep pattern="balance" path="design/gdd/" → find relevant GDDs
Glob pattern="design/balance/**/*.md" → find previous balance reports
- Read the GDD for the identified domain from
design/gdd/ - Read all relevant data files from
assets/data/ - Extract intended design targets, tuning knobs, and expected value ranges from the GDD
Phase 3: Delegate Expert Analysis
Spawn specialist agents via Task in parallel for the identified domain. Pass the full GDD content and data file content to each agent.
Combat balance → spawn systems-designer
Ask them to:
- Calculate DPS for all weapons/abilities at each power tier
- Check time-to-kill at each tier
- Identify any options that dominate all others (strictly better)
- Check if defensive options can create unkillable states
- Verify damage type/resistance interactions are balanced
- Produce a table of outliers with expected vs actual values
Economy balance → spawn economy-designer
Ask them to:
- Map all resource faucets and sinks with flow rates
- Project resource accumulation over time
- Check for infinite resource loops
- Verify gold sinks scale with gold generation
- Check if any items are never worth purchasing
- Produce a resource flow diagram in table form
What this file has done since we first saw it
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 striderZA/OpenCodeGameStudios (84 stars, last pushed 25d ago), licensed MIT. It adds 61 tokens to every session and 1,411 once invoked, about $0.0003 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 2026-09-03.
