What it is
Anthropic's own course catalog, hosted on Skilljar. Tracks cover Claude 101, Claude Code 101, Cowork, Agent Skills, MCP and the Claude API. Claude Code in Action is the deepest: plan mode, compaction, the rewind menu, hooks, permission modes, headless runs, GitHub Actions review and packaging plugins.
Why it earns a slot
Free, current, and written by the people who ship the tool, so it is right about defaults that blog posts get wrong. Best first stop once you are past single prompts and want longer unsupervised runs.
Know before you commit
Vendor training: it teaches the Anthropic way and never compares Claude Code with Cursor, Codex or Gemini CLI. Courses change as the product ships, so bookmarked lessons go stale.
