Your First Project

Launch SF

Open a terminal in any project directory (or an empty one) and run:

sf

SF shows a welcome screen with your version, active model, and available tool keys.

Start a Discussion

Type /sf to enter step mode. SF reads the state of your project directory and determines the next logical action:

• No .sf/ directory — starts a discussion flow to capture your project vision
• Milestone exists, no roadmap — discuss or research the milestone
• Roadmap exists, slices pending — plan the next slice or execute a task
• Mid-task — resume where you left off

For a new project, SF will ask you to describe what you want to build. Talk through your vision — SF captures requirements, architectural decisions, and scope.

The Project Hierarchy

After discussion, SF organizes your work into:

Milestone  →  a shippable version (4-10 slices)
  Slice    →  one demoable feature (1-7 tasks)
    Task   →  one context-window-sized unit of work

The key rule: a task must fit in one AI context window. If it can't, it becomes two tasks.

Run Auto Mode

Once you have a milestone and roadmap, let SF take the wheel:

/sf auto

SF autonomously:

1. Plans each slice — scouts the codebase, researches docs, decomposes into tasks
2. Executes each task — writes code in a fresh AI session
3. Completes the slice — writes summaries, commits with meaningful messages
4. Reassesses the roadmap — checks if the plan still makes sense
5. Repeats until the milestone is done

The Two-Terminal Workflow

The recommended approach: auto mode in one terminal, steering from another.

Terminal 1 — let it build:

sf
/sf auto

Terminal 2 — steer while it works:

sf
/sf discuss    # talk through architecture decisions
/sf status     # check progress
/sf queue      # queue the next milestone
/sf capture "add rate limiting to the API"  # fire-and-forget thought

Both terminals read and write the same .sf/ files. Decisions in terminal 2 are picked up at the next phase boundary automatically.

Check Progress

Press Ctrl+Alt+G or type /sf status to see the dashboard:

• Current milestone, slice, and task
• Elapsed time and phase
• Per-unit cost and token breakdown
• Completed and in-progress work

Resume a Session

sf --continue    # or sf -c

Resumes the most recent session for the current directory.

To browse and pick from all saved sessions:

sf sessions

Shows each session's date, message count, and preview so you can choose which to resume.

What's on Disk

All state lives in .sf/ inside your project:

.sf/
  PROJECT.md          — what the project is
  REQUIREMENTS.md     — requirement contract
  DECISIONS.md        — architectural decisions
  KNOWLEDGE.md        — cross-session rules and patterns
  STATE.md            — quick-glance status
  milestones/
    M001/
      M001-ROADMAP.md — slice plan with dependencies
      M001-CONTEXT.md — scope and goals
      slices/
        S01/
          S01-PLAN.md     — task decomposition
          S01-SUMMARY.md  — what happened
          S01-UAT.md      — test script
          tasks/
            T01-PLAN.md
            T01-SUMMARY.md
