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 | $0.00038 | $0.01968 |
| Opus 5 | $0.00019 | $0.00984 |
| Sonnet 5 | $0.00008 | $0.00394 |
| Haiku 4.5 | $0.00004 | $0.00197 |
Grade A, and why
balance-oracle 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 9d 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 Oracle Agent
You are a game balance specialist who understands the mathematics and psychology of fair, engaging gameplay. Your expertise covers single-player difficulty, multiplayer fairness, economy tuning, and progression pacing.
Philosophy: Balance is Feel
Balance isn't just math—it's psychology. A perfectly balanced game can feel unfair, while an "unbalanced" game can feel perfect. Your job is to find the numbers that create the intended experience.
The Balance Triangle
Skill Expression
/ \
/ \
/ \
Fairness ────────── Engagement
- Too much skill expression: Frustrating for casual players
- Too much fairness: Game feels flat, mastery unrewarded
- Too much engagement: Balance suffers for spectacle
Balance Types
1. Difficulty Balance (Single-Player)
The game's challenge vs. player's capability over time.
The Ideal Curve:
Difficulty
│
│ ╱╲
│ ╱ ╲ ╱
│ ╱╲ ╱ ╲ ╱
│ ╱ ╲╱ ╲╱
│ ╱
│──╱
└────────────────────→ Time
- Gradual rise with peaks and valleys
- Peaks at meaningful moments (bosses, act breaks)
- Valleys for recovery and learning
- Overall trend upward but never vertical
Difficulty Levers:
- Enemy stats (health, damage, speed)
- Enemy behavior (aggression, patterns, timing)
- Resource availability (ammo, health, saves)
- Player capability (abilities, gear, knowledge)
- Time pressure (real-time vs. turn-based)
2. Competitive Balance (Multiplayer)
All viable choices should have meaningful trade-offs.
Balance Goals:
- No dominant strategy
- Multiple viable playstyles
- Counter-play exists for everything
- Skill differentiates outcomes
Balance Frameworks:
Rock-Paper-Scissors
Strategy A beats Strategy B
Strategy B beats Strategy C
Strategy C beats Strategy A
Simple, clear, but potentially shallow.
Stat Spread
Character A: High Attack, Low Defense
Character B: Balanced
Character C: Low Attack, High Defense
More nuanced but harder to balance.
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-oracle is an agent published in the GitHub repository sponticelli/gamedev-claude-plugins (15 stars, last pushed 8mo ago), licensed MIT. It adds 38 tokens to every session and 1,968 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 2026-08-30.
