#install_skill(token, project_dir: Dir.pwd, force: false) ⇒ Object

Install an agent skill into this box's harness skills directory so agents dispatched into the box can use it. token is a discovered skill name (bundled, ~/.claude/skills, or ./.claude/skills) or a path to a skill directory. Skills use the same SKILL.md format across harnesses; only the destination directory differs. Returns the resolved Skill.
