MANDATORY Tool Restrictions

REQUIRED TOOLS — use these when specified in the process:

• AskUserQuestion — Preserve the one-question-at-a-time interaction pattern at every decision point marked with AskUserQuestion: in the process below. In Claude Code, use the tool. In Codex, ask one concise plain-text question at a time unless a structured question tool is actually available in the current mode. Do not narrate missing tools or fallbacks to the user.

BANNED TOOLS — calling these is a skill violation:

• EnterPlanMode — BANNED. Do NOT call this tool. This skill has its own structured process — planning (via detail skill) and execution (via build agents). Claude's built-in plan mode would bypass this entire orchestration. Follow the phases below instead.
• ExitPlanMode — BANNED. You are never in plan mode. There is nothing to exit.

If you feel the urge to "plan before acting" — that urge is satisfied by following the <process> phases below. Phase 0 creates the plan via the detail skill. Phases 1-7 execute it. Execute them directly. </tool_restrictions>

<arc_runtime> This workflow requires the full Arc bundle, not a prompts-only install.
