Quickstart
Get from zero to a completed spec, plan, and working implementation in under 10 minutes.
Make sure you’ve completed the Installation steps first.
1. Create a spec
Section titled “1. Create a spec”Navigate to your Flutter project (or create a new one) and start a Claude session:
cd my_flutter_appclaudeDescribe a feature you want to build:
/act-workflow-spec "add a settings screen with dark mode toggle and language selection"ACT will:
- Ask 2-4 clarifying questions to fill gaps
- Show you a preview outline for approval
- Generate a detailed specification with user flows, requirements, and edge cases
- Save it to
ai_specs/settings-spec.md
Review the spec. This is your chance to catch problems before any code is written.
2. Create a plan
Section titled “2. Create a plan”Turn the spec into a phased implementation plan:
/act-workflow-plan ai_specs/settings-spec.mdACT analyzes your codebase for conventions and patterns, then creates a plan with:
- Phases broken into concrete tasks with file paths
- TDD test-first tasks where applicable
- Verification steps for each phase
The plan is saved to ai_specs/settings-plan.md.
3. Build it
Section titled “3. Build it”Execute the plan:
/act-workflow-work ai_specs/settings-plan.mdACT will:
- Load Flutter knowledge (patterns, principles, breaking changes)
- Execute each phase in order
- Reconcile plan checkboxes and blocker notes after each completed phase
- Run
flutter analyzeandflutter testbefore each phase is considered done - Commit successful completed phases by default; pass
--do-not-committo keep changes local - Pass
--create-prto push and open a PR after the full plan succeeds
What just happened?
Section titled “What just happened?”You completed the full ACT workflow:
- Spec — defined what to build with clarity
- Plan — broke it into phases with concrete tasks
- Work — executed the plan with automated verification
The key insight: by spending a few minutes on the spec, you caught ambiguity before implementation. The AI had clear instructions, which means fewer bugs, less rework, and a better result.
