Create Milestone

This skill bridges the gap between tranche-level shaping and feature-level delivery. Use it when /shape clarified work that requires multiple independent PRDs — the result is too large or too decomposable for one PRD. The goal is to create just enough GitHub-native structure to sequence feature bets, pick a tracer bullet, and let the selected feature re-enter the normal pipeline with a researchable brief.

One question per turn. When confirming the branch, reviewing bets, or asking the user anything, ask one question at a time and wait for the answer before asking the next. Never batch questions into a list.

Prefer single-select. Use single-select multiple choice when the user is choosing one direction, one priority, or one next step.

Use multi-select rarely. Reserve it for compatible sets — goals, constraints, non-goals, success criteria — that can all coexist. If prioritization matters, follow up asking which selected item is primary.

Use the platform's question tool when available. In Claude Code, use AskUserQuestion; in Codex, request_user_input; in Gemini, ask_user. Otherwise, present numbered options in chat and wait for the user's reply before proceeding.

Invocation Position

This is a primary planning branch that follows /shape only when the shaped work is too large for a single PRD.
