gsd-onboard

<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.

• .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

<context> Arguments: $ARGUMENTS

• --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>
