ace-pm 35dc87ef53 chore: sync workspace state after rebrand
- Rebrand commits already in history (gsd → forge)
- Sync pre-existing doc, docker, and CI config updates
- All rebrand artifacts verified in place:
  * Native crates: forge-engine, forge-ast, forge-grep
  * Log prefixes: [forge] across 22+ files
  * Binary: ~/bin/sf-run
  * Workspace scopes: @sf-run/*, @singularity-forge/*
  * Nix flake: Rust toolchain ready

System ready for: nix develop && bun run build:native

Step Mode

Step mode is SF's interactive, one-step-at-a-time workflow. You stay in the loop, reviewing output between each step.

Starting Step Mode

/gsd

SF reads the state of your .gsd/ directory and presents a wizard showing what's completed and what's next. It then executes one unit of work and pauses.

How It Works

Step mode adapts to your project's current state:

State What Happens
No .gsd/ directory Starts a discussion flow to capture your project vision
Milestone exists, no roadmap Opens a discussion or research phase for the milestone
Roadmap exists, slices pending Plans the next slice or executes the next task
Mid-task Resumes where you left off

After each unit completes, you see results and decide what to do next. This is ideal for:

  • New projects where you want to shape the architecture
  • Critical work where you want to review each step
  • Learning how SF works before trusting auto mode

Steering During Step Mode

Between steps, you can:

  • Discuss/gsd discuss to talk through architecture decisions
  • Skip/gsd skip to prevent a unit from being dispatched
  • Undo/gsd undo to revert the last completed unit
  • Switch to auto/gsd auto to let SF continue autonomously

When to Use Step Mode

  • First milestone — Review SF's work before trusting it to run solo
  • Architectural decisions — When you want to guide the approach
  • Unfamiliar codebases — When you want to ensure SF understands the project
  • High-stakes changes — When mistakes would be costly

Transitioning to Auto Mode

Once you're comfortable with SF's approach, switch to auto mode:

/gsd auto

You can always press Escape to pause auto mode and return to step-by-step control.
