 The Phase 4 menu's visible option count varies by state: no requirements doc hides the review and Proof options, unresolved `Resolve Before Planning` hides `Plan implementation` and `Build it now`, a failing direct-to-work gate hides `Build it now`. Count the visible options for the current state and choose the rendering mode accordingly:
 
-- **4 or fewer visible:** use the platform's blocking question tool (`AskUserQuestion` in Claude Code — call `ToolSearch` with `select:AskUserQuestion` first if its schema isn't loaded; `request_user_input` in Codex; `ask_user` in Gemini, `ask_user` in Pi (requires the `pi-ask-user` extension)). This is the default per the plugin AGENTS.md "Interactive Question Tool Design" section.
-- **5 or more visible:** render as a numbered list in chat. This is the narrow case-3 overflow exception documented in the same AGENTS.md section; trimming would hide legitimate choices (plan, review, Proof, build, refine, pause are all distinct destinations).

+- **5 or more visible:** render as a numbered list in chat. This is the narrow option-overflow fallback; trimming would hide legitimate choices (plan, review, Proof, build, refine, pause are all distinct destinations). Include a hint that free-form input is accepted ("Pick a number or describe what you want.") so the numbered list retains the blocking tool's open-endedness.
 
 Never silently skip the question.
