MANDATORY Tool Restrictions

REQUIRED TOOLS — use these when indicated:

• AskUserQuestion — Preserve the one-question-at-a-time interaction pattern. 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 testing workflow. Execute it directly.
• ExitPlanMode — BANNED. You are never in plan mode. </tool_restrictions>

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

Paths in this skill use these conventions:
