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.
Use /create-milestone when:
/shapealready produced a closing summary with choices, assumptions, impositions, and structural signals- the shaped work requires multiple independent PRDs rather than one bounded feature

pre-merge
Primary pipeline review step after verified implementation. Use to create a PR with lineage and run architectural review before merge. Not for QA intake, planning, or implementation work.
22execute
Primary pipeline execution step after /prd-to-issues or for clearly scoped implementation work. Use to build, verify, and commit a concrete slice, delegating to /tdd for backend work and behavior-heavy frontend logic when red-green-refactor will reduce risk. Not for shaping or pre-merge review.
21write-a-prd
Primary pipeline shaping step after /research and before /prd-to-issues. Use when the problem is understood well enough to turn into a bounded PRD issue. May invoke /design-an-interface or /api-design-review when interface or contract uncertainty remains. Not for discovery, decomposition, or implementation-ready work.
14research
Primary pipeline step after /shape and before /write-a-prd. Use to verify current docs, versions, repo patterns, and key unknowns before shaping. Invokes /api-design-review when API contract risk is high. Not for underdefined problems or implementation-ready work.
13prd-to-issues
Primary pipeline decomposition step after /write-a-prd. Use when a shaped PRD is ready to become implementation-ready slices with boundary maps and dependency order. Not for unresolved scope, appetite, or solution direction.
13improve-pipeline
Optional meta-skill for improving `chrislacey89/skills` from real-world friction or breakdowns discovered while using the pipeline in another repo. Use when the main lesson is about the pipeline itself, not the downstream project. Grounds proposals in established software-engineering guidance from `/library`. Produces a GitHub issue in `chrislacey89/skills` and only moves to implementation after review.
