Claude Code

Anthropic's agentic coding tool. Runs in the terminal with full project context, executes commands, edits across files. Skills are a first-class primitive: folders with a SKILL.md that Claude loads when the task matches.

How skills install

Drop a skill folder into ~/.claude/skills/ (personal) or .claude/skills/ (project). Plugins can bundle skills and install from marketplaces.
