Three new commands for managing ideas and cross-session context:
/gsd:add-backlog <description>
Adds a 999.x numbered backlog item to ROADMAP.md. Creates phase directory
immediately so /gsd:discuss-phase and /gsd:plan-phase work on them.
No dependencies, no sequencing — pure parking lot.
/gsd:review-backlog
Lists all 999.x items, lets user promote to active milestone, keep, or
remove. Promotion renumbers to next sequential phase with proper deps.
/gsd:thread [name | description]
Three modes:
- No args: list all threads with status
- Existing name: resume thread, load context
- New description: create thread from current conversation context
Threads live in .planning/threads/ as lightweight markdown files with
Goal, Context, References, and Next Steps sections.
Design:
- Self-contained command files, no core changes needed
- 999.x numbering keeps backlog out of active sequence
- Threads are independent of phases — cross-session knowledge stores
- Both features compose with existing GSD commands
Fixes#1005
