sdd-new-phase
Most recent maintenance signal among this shortlist.
| Signal | sdd-new-phase Append a new active phase to specs/roadmap.md. Parses existing phases (active and ✅-completed) to compute the next stable phase number per the lifecycle rule, grounds the proposal against specs/mission.md and specs/tech-stack.md, groups structured questions (goal, dependencies, priority) via AskUserQuestion, then collects a freeform bullet list for the phase body. Edits specs/roadmap.md in place, then invokes the built-in /review skill against the pending change before stopping — committing, pushing, and opening a PR are left to the user. Does not create a feature spec; that is /sdd-new-spec's job. | openspec-verify-change Verify implementation matches OpenSpec change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving. Also use when the user says "openspec verify" or "opsx verify". |
