Use when working with ANY GPU rendering, Metal, OpenGL migration, shaders, frame rate, or display performance. Covers Metal migration, shader conversion, variable refresh rate, ProMotion, render loops.
/plugin marketplace add CharlesWiltgen/Axiom/plugin install axiom@axiom-marketplaceThis skill inherits all available tools. When active, it can use any tool Claude has access to.
You MUST use this skill for ANY GPU rendering, graphics programming, or display performance work.
Use this router when:
Strategy decisions → /skill axiom-metal-migration
API reference & conversion → /skill axiom-metal-migration-ref
Diagnostics → /skill axiom-metal-migration-diag
Frame rate & render loops → /skill axiom-display-performance
User asks about GPU/graphics/Metal/display
├─ "Should I use translation layer or native?" → metal-migration
├─ "How do I migrate/port/convert?" → metal-migration
├─ "Show me the API/code/example" → metal-migration-ref
├─ "How do I set up MTKView?" → metal-migration-ref
├─ "Something's broken/wrong/slow" → metal-migration-diag
├─ "Stuck at 60fps on ProMotion" → display-performance
├─ "CADisplayLink setup/configuration" → display-performance
├─ "Variable refresh rate issues" → display-performance
└─ "Frame rate not what I expect" → display-performance

This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
