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.

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.

<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.

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.
