<arguments>$ARGUMENTS</arguments>

The text inside `<arguments>` is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.

<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: see the `<arguments>` block above.

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 rules for nested interactive commands. </process>
