Game Development Skills

Hexclave's private collection of reusable skills for building production-quality games with coding agents.

The repository follows the Agent Skills specification and the multi-skill layout used by vercel-labs/agent-skills. Each installable skill lives under skills/<skill-name>/ with its own SKILL.md and supporting files.

Available skills

production-game-builder

Builds or substantially redesigns playable games with a production workflow covering:

• a complete playable loop and explicit game-state lifecycle;
• responsive controls, vehicle handling, cameras, and layered feedback;
• reference-driven art direction and game-native UI;
• coherent asset, lighting, world-building, and audio pipelines;
• truthful gameplay metrics, online state, and leaderboards;
• measured rendering performance, LOD, culling, and frame pacing;
• browser and Three.js implementation guidance;
• runtime, visual, deployment, and licensing verification.

Validate and package

npm ci --ignore-scripts
npm run build:discovery -- https://example.com/skills

The command validates every skill's frontmatter and produces dist/index.json plus one deterministic archive per skill. Pushes to main also publish an immutable GitHub release containing those artifacts.

Adding a skill

1. Create skills/<skill-name>/SKILL.md.
2. Include valid name and description YAML frontmatter.
3. Keep the frontmatter name identical to the folder name.
4. Add supporting files under references/, scripts/, assets/, or agents/ as needed.
5. Add the skill name to the appropriate group in skills.sh.json.
6. Run the validation and packaging command before pushing.
