Custom commands (defined in .arctic/command/) also appear in slash command autocomplete.

Custom Commands

Commands are defined as markdown templates in:

• Project: .arctic/command/*.md
• Global: ~/.config/arctic/command/*.md

Each command file uses frontmatter:

---
description: "Review changes"
model: "provider/model"
agent: "build"
subtask: true
---

Review the following changes:
{{diff}}

Invoke with:

arctic run --command review

Or in the TUI with /review.

Import from Claude Code

Arctic can import commands from Claude Code on first launch:

• Project commands: .claude/commands/ → .arctic/command/claude/
• Global commands: ~/.claude/commands/ → ~/.config/arctic/command/claude/

You'll be prompted once. Imported commands work immediately as slash commands in the TUI.
