A command is a .md file under .claude/commands/ with YAML frontmatter — description, an optional argument-hint, and allowed-tools scoping what the command may use.
Unlike a skill, a command never loads itself: you invoke it explicitly by typing its name, e.g. /dk-review.
Dotboost ships ten, covering the lifecycle of a change from a fresh clone through to a PR-ready diff. See Reference for the full list, grouped by workflow stage.
Use a command when you want a specific, repeatable procedure to run on demand — bootstrapping a clone, running the QA gate, writing a feature doc.
Use a skill when you want Claude to know something automatically while it works on unrelated tasks — a naming convention, a validation pattern, a security rule.
Several commands lean on skills internally; /dk-module, for instance, is built on top of dotkernel-dot-maker and dotkernel-module-structure rather than duplicating their guidance.
