<objective> Reverse-migrate a GSD-2 project (.gsd/ directory) back to GSD v1 (.planning/) format.

Maps the GSD-2 hierarchy (Milestone → Slice → Task) to the GSD v1 hierarchy (Milestone sections in ROADMAP.md → Phase → Plan), preserving completion state, research files, and summaries.

CJS-only: from-gsd2 is not on the bm-sdk query registry; call gsd-tools.cjs as shown below (see docs/CLI-TOOLS.md). </objective>

<process>

1. Locate the .gsd/ directory — check the current working directory (or --path argument):

``bash node "${CLAUDE_PLUGIN_ROOT:-$(ls -d "$HOME/.claude/plugins/cache/gsd-plugin/gsd/"*/ 2>/dev/null|sort -V|tail -1)}/bin/gsd-tools.cjs" from-gsd2 --dry-run ` If no .gsd/` is found, report the error and stop.

1. Show the dry-run preview — present the full file list and migration statistics to the user. Ask for confirmation before writing anything.

1. Run the migration after confirmation:

``bash node "${CLAUDE_PLUGIN_ROOT:-$(ls -d "$HOME/.claude/plugins/cache/gsd-plugin/gsd/"*/ 2>/dev/null|sort -V|tail -1)}/bin/gsd-tools.cjs" from-gsd2 ` Use --force if .planning/` already exists and the user has confirmed overwrite.

1. Report the result — show the filesWritten count, planningDir path, and the preview summary.

</process>

<notes>

• The migration is non-destructive: .gsd/ is never modified or removed.
• Pass --path <dir> to migrate a project at a different path than the current directory.
• Slices are numbered sequentially across all milestones (M001/S01 → phase 01, M001/S02 → phase 02, M002/S01 → phase 03, etc.).
• Tasks within each slice become plans (T01 → plan 01, T02 → plan 02, etc.).
• Completed slices and tasks carry their done state into ROADMAP.md checkboxes and SUMMARY.md files.
• GSD-2 cost/token ledger, database state, and VS Code extension state cannot be migrated.
