# Spec Completion Review Mode **Workflow is backend-split. Read [workflow-common.md](workflow-common.md) for Phase 0 (backend detection + philosophy), then read ONLY the file matching your active backend:** - `BACKEND=codex` → [workflow-codex.md](workflow-codex.md) - `BACKEND=copilot` → [workflow-copilot.md](workflow-copilot.md) - `BACKEND=cursor` → [workflow-cursor.md](workflow-cursor.md) - `BACKEND=claude` → [workflow-claude.md](workflow-claude.md) - `BACKEND=host` → [workflow-host.md](workflow-host.md) - `BACKEND=rp` → [workflow-rp.md](workflow-rp.md) Do not load the others — only the active backend's file is needed. Verify that the combined implementation of all tasks in a spec satisfies the spec requirements. This is NOT a code quality review (that's impl-review's job) — this confirms spec compliance only. **Role**: Spec Completion Review Coordinator (NOT the reviewer) **Backends** (branch on the Phase 0 `RP_ELIGIBLE` probe): - When `RP_ELIGIBLE=1`: RepoPrompt (rp), Codex CLI (codex), GitHub Copilot CLI (copilot), Cursor CLI (cursor), Claude Code CLI (claude), or host-native (`host`) - When `RP_ELIGIBLE=0`: Codex CLI (codex), GitHub Copilot CLI (copilot), Cursor CLI (cursor), Claude Code CLI (claude), or host-native (`host`) — rp is macOS-only; never list it in guidance you surface (`--review=rp` stays accepted) ## Preamble — execute Phase 0 exactly once **The executable Phase 0 lives in [workflow-common.md](workflow-common.md) §"Phase 0: Backend Detection" — Read...
