Games Expert

Portable, version-aware gaming expertise for Codex, Claude Code, and Gemini CLI.

Games Expert is an extensible collection of focused Agent Skills that helps AI assistants answer gameplay questions with the right game, mode, platform, progression stage, and patch context. It keeps stable game knowledge local while directing time-sensitive questions—such as patches, seasons, rotations, events, prices, and current meta—to fresh sources.

No API keys, background services, or runtime dependencies are required.

Why separate skills?

Each game has its own skill and reference material. The assistant loads only the relevant game context instead of injecting one large gaming prompt into every conversation. This improves routing, reduces irrelevant context, and makes each game easier to maintain independently.

The plugin does not retrain or fine-tune the underlying model. It supplies reusable instructions, decision rules, source guidance, and domain references at answer time.

Install

Codex and ChatGPT desktop

Add the GitHub repository as a plugin marketplace, then install the plugin:

codex plugin marketplace add erhan/games-expert
codex plugin add games-expert@games-expert

Restart the desktop app or begin a new conversation after installation so the skills are discovered.

Claude Code

Add the repository as a marketplace and install the plugin:

claude plugin marketplace add erhan/games-expert
claude plugin install games-expert@games-expert

For local development without installing:

git clone https://github.com/erhan/games-expert.git
claude --plugin-dir ./games-expert

Gemini CLI

Install the repository as a Gemini CLI extension:

gemini extensions install https://github.com/erhan/games-expert.git --auto-update

Restart Gemini CLI after installation. Gemini discovers the Agent Skills in the root skills/ directory.

For local development:

git clone https://github.com/erhan/games-expert.git
gemini extensions link ./games-expert

Usage examples

The skills are designed for automatic invocation. Ask naturally:

“I am at Furnace 30 and mostly F2P in Whiteout Survival. What should I save for SvS?”
“Review my Gen 3 Whiteout Survival heroes and suggest a Bear Hunt formation.”
“Design a reliable iron farm for Minecraft Java and list the materials.”
“Give me a low-spoiler Elden Ring strength build for level 80.”
“How should I play this VALORANT retake with a controller?”
“Create a four-week League of Legends improvement plan for a Gold support player.”

For better answers, include relevant details such as the game version, platform, mode, rank, progression stage, state age, hero generation, spending style, or spoiler preference.

Accuracy and freshness

The shared source policy instructs assistants to:

separate stable mechanics from version-sensitive information;
verify patches, seasons, rotations, events, prices, codes, and current meta;
prefer official patch notes, support pages, and developer documentation;
label community-derived strategy and avoid inventing exact values;
distinguish platform, edition, mode, server, state age, and progression differences;
avoid cheats, account theft, exploit automation, and real-money trading fraud.

Game publishers change live-service systems frequently. Always verify high-cost or irreversible in-game decisions against the current game client and official announcements.

Contributing

Contributions are welcome. Useful contributions include:

a focused skill for another game;
corrections to outdated or ambiguous guidance;
better official source links;
clearer routing between editions, modes, platforms, or progression stages.

Keep skills concise. Put game-specific details in that game's references/ directory, keep time-sensitive claims out of static instructions, and include official sources whenever possible.
