gsd-from-gsd2

<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. </objective>

<process>

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

   node ".github/get-shit-done/bin/gsd-tools.cjs" from-gsd2 --dry-run
   

   If no .gsd/ is found, report the error and stop.

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

3. Run the migration after confirmation:

   node ".github/get-shit-done/bin/gsd-tools.cjs" from-gsd2
   

   Use --force if .planning/ already exists and the user has confirmed overwrite.

4. 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. </notes>
