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 | $0.00039 | $0.00774 |
| Opus 5 | $0.00019 | $0.00387 |
| Sonnet 5 | $0.00008 | $0.00155 |
| Haiku 4.5 | $0.00004 | $0.00077 |
Grade A, and why
balance-data-change-review 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 Data Change Review
Overview
Review balance changes as data contracts with intent, bounds, dependencies, and rollback conditions rather than approving isolated numbers by feel.
When to use
Use for stat tables, abilities, cooldowns, drop rates, XP curves, encounter tuning, rewards, crafting values, and configuration-driven balance patches.
When NOT to use
Do not use to write generated tables directly, deploy live configuration, or replace playtest and telemetry evidence.
Required inputs and context discovery
Collect source-of-truth path, generated outputs, baseline and proposed rows, design intent, allowed bounds, formulas, dependent systems, segment impact, test evidence, rollout scope, and rollback owner.
Safety and risk level
Read-only review. Source data may be changed only by its named owner through the project generation pipeline; generated outputs are never hand-edited.
Workflow
- Verify source ownership, generation path, schema, and baseline snapshot. Completion criterion: the canonical editable source and generated consumers are identified.
- Compute field-level deltas and compare them with declared bounds. Completion criterion: every changed value has old, new, absolute, relative, and bound status.
- Trace formulas, dependencies, breakpoints, and player-segment effects.
Completion criterion: hidden multipliers and downstream consumers are documented or
BLOCKED. - Review design evidence, exploit risk, and rollback conditions. Completion criterion: intent is testable and rollback restores the exact baseline.
- Issue a review verdict and required validation plan. Completion criterion: approval is withheld for unexplained, out-of-bound, or untestable changes.
Evidence and output contract
Produce balance-change-review.json with source identity, deltas, bound violations, dependency impacts, evidence, risks, rollback data, verdict, and required tests.
Handoff contract
Record canonical source, generation command, affected systems, unresolved dependencies, review owner, validation build, rollout scope, and rollback snapshot.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-data-change-review is a skill published in the GitHub repository hoatv2211/GameStudio-CodexKIT (3 stars, last pushed 3d ago), licensed MIT. It adds 39 tokens to every session and 774 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.
