Generic/Codex entrypoint for masterplan: bare /masterplan, /masterplan:masterplan, $masterplan, or any verb. All verbs (full, brainstorm, plan, execute, finish, retro, import, doctor, status, validate, stats, clean, next, verbs, render, publish, follow) route through this single command — v8 ships NO per-verb /masterplan:<verb> skills (they shadowed Claude Code built-ins like /plan, /status, /doctor and added nothing over bare-command routing).
Suggest `/masterplan import` when legacy planning artifacts (PLAN.md, TODO.md, ROADMAP.md, pre-v3 superpowers plans/status files, branches without merged PRs, draft PRs with task lists) exist in the repo. Surfaces a one-line suggestion only — never auto-runs.
