<runtime_note> **Copilot (VS Code):** Use `vscode_askquestions` wherever this workflow calls `AskUserQuestion`. They are equivalent — `vscode_askquestions` is the VS Code Copilot implementation of the same interactive question API. </runtime_note> <objective> Guide brownfield onboarding for an existing codebase by routing through the existing GSD primitives in the safe order: codebase map → docs ingest → project initialization → onboarding summary. **Creates or confirms:** - `.planning/codebase/` — evidence-backed codebase map from `/gsd-map-codebase` - `.planning/PROJECT.md`, `REQUIREMENTS.md`, `ROADMAP.md`, `STATE.md` — project setup from `/gsd-new-project` or `/gsd-ingest-docs` - `.planning/onboarding/SUMMARY.md` — lightweight index of what was learned and the next command **Non-goals:** This command does not execute phases, ship work, or overwrite existing planning artifacts without an explicit gate. </objective> <execution_context> @~/.claude/gsd-core/workflows/onboard.md @~/.claude/gsd-core/references/ui-brand.md @~/.claude/gsd-core/references/gate-prompts.md </execution_context> <context> Arguments: $ARGUMENTS Flags: - `--fast` — prefer `/gsd-map-codebase --fast` for the mapping handoff; the complete map is still required before `/gsd-new-project`. - `--text` — use plain-text numbered lists instead of TUI menus. </context> <process> Execute the onboard workflow end-to-end. Preserve all safety gates, text-mode fallbacks, idempotency checks, and top-level handoff ...
