Adds --interactive flag to /gsd:execute-phase that changes execution from
autonomous subagent delegation to sequential inline execution with user
checkpoints between tasks.
Interactive mode:
- Executes plans sequentially inline (no subagent spawning)
- Presents each plan to user: Execute, Review first, Skip, Stop
- Pauses after each task for user intervention
- Dramatically lower token usage (no subagent overhead)
- Maintains full GSD planning/tracking structure
Changes:
- execute-phase.md: new check_interactive_mode step with full interactive flow
- execute-phase command: documented --interactive flag in argument-hint and context
Use cases:
- Small phases (1-3 plans, no complex dependencies)
- Bug fixes and verification gap closure
- Learning GSD workflow
- When user wants to pair-program with Claude under GSD structure
