Install
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill platformerInstalls only this skill. Add -a claude-code (puts it in .claude/skills/), -a codex or -a cursor (.agents/skills/) to choose the agent, and -g to install it for your user instead of the project.
Commands are copied from the project's README. Check the repository before running anything on your machine.
Install for a specific agent
| Agents | -a | Folder |
|---|---|---|
| Claude Code | claude-code | .claude/skills/ |
| Codex | codex | .agents/skills/ |
| Cursor | cursor | .agents/skills/ |
| Gemini CLI | gemini-cli | .agents/skills/ |
| GitHub Copilot | github-copilot | .agents/skills/ |
| OpenCode | opencode | .agents/skills/ |
| Windsurf | windsurf | .windsurf/skills/ |
Add -a <flag> to the command. These are project folders; add -g to install for your user account instead.
What you get
- Worked steps: Solve jump physics from height + time; Coyote time + jump buffer + variable height; One-way platforms
- A pitfalls section with the mistakes to avoid
- Bundled 1 reference doc the agent reads when needed
Good fit
- A platformer or Mario/Celeste-like, or tuning jump feel
