game-server-securityReview multiplayer authority, RPCs, sessions, authorization, replication, inventory, economy, purchases, retries, and replay.
Game Server Security is an agent skill from gmh5225/awesome-game-security. Review multiplayer authority, RPCs, sessions, authorization, replication, inventory, economy, purchases, retries, and replay. Use when server or backend state is the security boundary.
Its SKILL.md is about 260 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/repository-resources.md`, `references/review-guide.md` and `references/time-ordering-and-replay.md`).
It sits in Game Development, covering Multiplayer and networking, Database administration and Authorization and RBAC. The repository describes itself as: awesome game security [Welcome to PR]. The licence is MIT.
Read from SKILL.md and the folder at commit 8502288. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Game Server Security loads about 258 tokens when it runs, and up to ~5.2k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 81 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/game-server-security/SKILL.md (or your agent's skills folder). This skill also uses 3 other files; get the full folder from GitHub.Trace one consequential operation across client, transport, server, backend, provider, and durable state. Authentication is an input to authorization, not a substitute for it.
Use anti-cheat-systems for detector enforcement, game-engine-resources for engine replication models, and game-supply-chain-security for released server or plugin artifacts.

Review multiplayer authority, RPCs, sessions, authorization, replication, inventory, economy, purchases, retries, and replay. Game Server Security is an agent skill from gmh5225/awesome-game-security. Review multiplayer authority, RPCs, sessions, authorization, replication, inventory, economy, purchases, retries, and replay.
Game Server Security fits situations like: backend state is the security boundary; tasks that involve Multiplayer and networking; tasks that involve Database administration.
Run `npx skills add gmh5225/awesome-game-security --skill game-server-security -a claude-code`. Or copy the skill folder (.claude/skills/game-server-security in gmh5225/awesome-game-security) into .claude/skills/game-server-security in your project. Claude Code loads it when a task matches its description.
Run `npx skills add gmh5225/awesome-game-security --skill game-server-security -a codex`. Or copy the skill folder (.claude/skills/game-server-security in gmh5225/awesome-game-security) into .agents/skills/game-server-security in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add gmh5225/awesome-game-security --skill game-server-security -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/game-server-security, .gemini/skills/game-server-security, .github/skills/game-server-security and .opencode/skills/game-server-security in your project.
SKILL.md names no scripts, command-line tools or credentials: Game Server Security is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Game Server Security is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 258 tokens (SKILL.md is roughly 1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 5k tokens, read only when the agent opens those files.
