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 | $0.00040 | $0.00710 |
| Opus 5 | $0.00020 | $0.00355 |
| Sonnet 5 | $0.00008 | $0.00142 |
| Haiku 4.5 | $0.00004 | $0.00071 |
Grade A, and why
network-authority-and-exploit-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 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.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Network Authority and Exploit Review
Overview
Review who may request, validate, authorize, rate-limit, persist, and broadcast sensitive game actions without performing offensive testing.
When to use
Use for client-authoritative currency, inventory, combat, movement, reward, trade, admin, replay, duplication, or rate-limit concerns.
When NOT to use
Do not use to send exploit payloads, bypass authentication, scan external systems, or replace an authorized penetration test.
Required inputs and context discovery
Collect action list, trust boundaries, initiators, authoritative side, server validation, idempotency, replay protection, rate limits, persistence, audit logs, and supported threat assumptions.
Safety and risk level
Read-only static review. No live traffic, credential use, service control, player-data access, or exploit proof is authorized.
Workflow
- Map clients, gateways, servers, databases, and administrative trust boundaries. Completion criterion: every sensitive transition has an owner.
- Inventory sensitive actions and their authoritative side. Completion criterion: client-authoritative sensitive state is visible.
- Review validation, idempotency, replay, sequencing, and rate-limit guards. Completion criterion: missing guards become discrete findings.
- Trace persistence and broadcast behavior for abuse amplification. Completion criterion: exploit impact is bounded without attack execution.
- Rank source fixes and safe regression simulations. Completion criterion: live exploit attempts remain BLOCKED.
Evidence and output contract
Produce network-authority-review.json with trust boundaries, action contracts, findings, severity rationale, limitations, and defensive tests.
Handoff contract
Record reviewed actions, authority decisions, missing guards, sensitive paths, untested live assumptions, and next defensive owner.
Pitfalls and anti-rationalization
- Encryption does not replace server authority.
- A client UI restriction is not server validation.
- Do not prove impact on a live environment.
- Static review does not certify exploit absence.
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.

network-authority-and-exploit-review is a skill published in the GitHub repository hoatv2211/GameStudio-CodexKIT (3 stars, last pushed 2d ago), licensed MIT. It adds 40 tokens to every session and 710 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.
