- New command /plan-milestones: generates docs/milestones/ (roadmap.md + one document per milestone with its features, acceptance criteria, and ready-to-run /add-feature commands) - New skill milestone-planning: MVP-first vertical-slice planning rules + milestone/roadmap templates - /add-feature: reads the feature's milestone document before planning and checks the feature off (updating milestone/roadmap status) in Step 8 - Workflow diagrams, CLAUDE.md, README, and settings.json updated for the new phase Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Milestone Documents (docs/milestones/)
This directory holds the project's milestone plan: an ordered breakdown of the product into releases, with the features for each milestone. It is created by /plan-milestones and kept up to date by /add-feature.
Structure

File purposes
roadmap.md
The overview: a table of all milestones (goal, feature count, status), the ordering rationale, a pointer to the current milestone, and a "Later / Icebox" list of consciously deferred items.
milestone-[NN]-[name].md
One document per milestone. Contains the milestone's goal, scope, dependencies, and its feature list — each feature sized for exactly one /add-feature run, with description, related PRD requirements, affected screens, acceptance criteria, and the ready-to-run command.
Status tracking
- Each feature has a checkbox in its milestone document;
/add-featurechecks it off ([ ]→[x]) when the feature completes. - Milestone status (
Not started/In progress/Completed) is kept in sync between the milestone document and the roadmap table.
Workflow
/setup-project → product/architecture docs
/define-design → UI/UX design spec
/generate-app → initial app shell
/plan-milestones → creates the files above
/add-feature → implements one feature, then checks it off here
Status
This directory is populated by running /plan-milestones. Until then, the files above do not exist.
