Host	Start the course	Start Model Context Protocol (MCP)	Start Agent Skills	Run a phase quiz
Codex	`start-learning`, or choose it from `/skills`	`learn-mcp`, or choose it from `/skills`	`learn-agent-skills`, or choose it from `/skills`	`check-understanding 13`, or choose it from `/skills`
Claude Code	`/start-learning`	`/learn-mcp`	`/learn-agent-skills`	`/check-understanding 13`
Other compatible hosts	`Use start-learning to begin the course.`	`Use learn-mcp to start the Model Context Protocol (MCP) path.`	`Use learn-agent-skills to start the Agent Skills Engineering path.`	`Use check-understanding to quiz me on Phase 13.`

Skill	What it does
`start-learning`	One-time onboarding: why you're learning, placement quiz, personalized plan saved to `LEARNING.md`.
`learn`	The tutor loop. Warm-up recall, then the next lesson taught interactively, then its quiz; records progress and a review queue.
`course-guide`	Topic router. "Where do I learn attention?" or "my loss is NaN" → the exact lessons, with links.
`learn-mcp`	Focused Model Context Protocol (MCP) tutor. Creates `MCP-LEARNING.md`, follows the 17-lesson manifest, and records wire, security, reliability, and conformance evidence.
`learn-agent-skills`	Focused Agent Skills tutor. Creates `AGENT-SKILLS-LEARNING.md`, teaches lessons 22, 24, 25, 26, and 27, and records real-host evidence.
`learn-reverse-engineering`	Focused Reverse Engineering tutor. Creates `REVERSE-ENGINEERING-LEARNING.md`, teaches Phase 13 lessons 32 to 45 on programs you build yourself, and records lab evidence.
`claude-certification`	Certification tutor. Chooses CCAO-F, CCDV-F, CCAR-F, or CCAR-P; teaches each lesson; runs labs; reviews artifacts; administers diagnostics and mocks; saves progress.
`mcpa-certification`	MCPA tutor. Follows the 34-lesson `mcpa-f` route on the 2026-07-28 protocol; teaches each lesson; runs labs and the wire checker; administers the diagnostic and three mocks; saves progress.
`find-your-level`	Ten-question placement quiz. Maps your knowledge to a starting phase and produces a personalized path with hour estimates.
`check-understanding <phase>`	Per-phase quiz, eight questions, with feedback and specific lessons to review. Use the Codex, Claude Code, or natural-language form in the invocation table above.
