Gsd Orchestrator

Build something from scratch: Read workflows/build-from-spec.md — write spec, init directory, launch, monitor, verify.

Check on a running or completed build: Read workflows/monitor-and-poll.md — query state, interpret phases, handle blockers.

Execute with fine-grained control: Read workflows/step-by-step.md — run one unit at a time with decision points.

Understand the JSON output: Read references/json-result.md — field reference for HeadlessJsonResult.

Pre-supply answers or secrets: Read references/answer-injection.md — answer file schema and injection mechanism.

Look up a specific command: Read references/commands.md — full command reference with flags and examples. </routing>

<quick_reference>

Launch a full build (spec to working code):

mkdir -p /tmp/my-project && cd /tmp/my-project && git init
cat > spec.md << 'EOF'
# Your Product Spec Here
Build a ...
EOF
gsd headless --output-format json --context spec.md new-milestone --auto 2>/dev/null

Check project state (instant, free):

cd /path/to/project
gsd headless query | jq '{phase: .state.phase, progress: .state.progress, cost: .cost.total}'

Resume work on an existing project:

cd /path/to/project
gsd headless --output-format json auto 2>/dev/null

Run one step at a time:

RESULT=$(gsd headless --output-format json next 2>/dev/null)
echo "$RESULT" | jq '{status: .status, phase: .phase, cost: .cost.total}'

<project_structure> GSD creates and manages all state in .gsd/:

.gsd/
  PROJECT.md          # What this project is
  REQUIREMENTS.md     # Capability contract
  DECISIONS.md        # Architectural decisions (append-only)
  KNOWLEDGE.md        # Persistent project knowledge (patterns, rules, lessons)
  STATE.md            # Current phase and next action
  milestones/
    M001-xxxxx/
      M001-xxxxx-CONTEXT.md    # Scope, constraints, assumptions
      M001-xxxxx-ROADMAP.md    # Slices with checkboxes
      M001-xxxxx-SUMMARY.md    # Completion summary
      slices/S01/
        S01-PLAN.md            # Tasks
        S01-SUMMARY.md         # Slice summary
        tasks/
          T01-PLAN.md          # Individual task spec
          T01-SUMMARY.md       # Task completion summary

State is derived from files on disk — checkboxes in ROADMAP.md and PLAN.md are the source of truth for completion. You never need to edit these files. GSD manages them. But you can read them to understand progress. </project_structure>

<answer_injection> Pre-supply answers and secrets for fully autonomous runs:

gsd headless --answers answers.json --output-format json auto 2>/dev/null

{
  "questions": { "question_id": "selected_option" },
  "secrets": { "API_KEY": "sk-..." },
  "defaults": { "strategy": "first_option" }
}

• questions — question ID to answer (string for single-select, string[] for multi-select)
• secrets — env var to value, injected into child process environment
• defaults.strategy — "first_option" (default) or "cancel" for unmatched questions

See references/answer-injection.md for the full mechanism. </answer_injection>

<event_streaming> For real-time monitoring, use JSONL event streaming:

gsd headless --json auto 2>/dev/null | while read -r line; do
  TYPE=$(echo "$line" | jq -r '.type')
  case "$TYPE" in
    tool_execution_start) echo "Tool: $(echo "$line" | jq -r '.toolName')" ;;
    extension_ui_request) echo "GSD: $(echo "$line" | jq -r '.message // .title // empty')" ;;
    agent_end) echo "Session ended" ;;
  esac
done

Filter to specific events: --events agent_end,execution_complete,extension_ui_request

Available types: agent_start, agent_end, tool_execution_start, tool_execution_end, tool_execution_update, extension_ui_request, message_start, message_end, message_update, turn_start, turn_end, cost_update, execution_complete. </event_streaming>
