Architecture Principles

1. Monorepo patterns: Shared UI from packages/ui, shared logic to packages/*
2. DB schema: All tables in ai_prompt schema
3. Data layer: Supabase client in lib/ideas.ts, React Query for state
4. Soft delete: Use deleted_at column, never hard delete
5. RLS policies: Owner can CRUD, authenticated can read

Key Patterns

Data Fetching (React Query)

const { data: ideas } = useQuery({
  queryKey: ["ideas", filters],
  queryFn: () => listIdeas(filters),
});

const mutation = useMutation({
  mutationFn: createIdea,
  onSuccess: () => queryClient.invalidateQueries({ queryKey: ["ideas"] }),
});

Type Transformations

DB uses label, UI uses name for tags:

function transformTag(dbTag: PmIdeaTag): IdeaTag {
  return { ...dbTag, name: dbTag.label };
}

"Continue to..." Actions

Ideas can convert to:

• Project → pm_projects (sets idea status to 'converted')
• Goal → pm_goals (links to existing project)
• Workflow → workflows (optional project link)
• Prompt → prompts + prompt_versions

Development Workflow

1. New feature: Plan with brainstorming skill first
2. DB changes: Create migration in supabase/migrations/
3. Types: Update src/types/ideas.ts
4. Data layer: Add functions to src/lib/ideas.ts
5. Components: Build in src/components/
6. Pages: Add routes in src/App.tsx
7. Tests: Use test-writer skill
8. Docs: Update /Docs/idea-machina/

Common Tasks

Add New Field to Ideas

1. Migration: ALTER TABLE ai_prompt.pm_ideas ADD COLUMN ...
2. Types: Update PmIdea and IdeaWithDetails
3. Form: Add field to IdeaForm.tsx
4. Card: Display in IdeaCard.tsx if needed

Add New "Continue to..." Action

1. Types: Add payload interface in types/ideas.ts
2. Data: Add function in lib/ideas.ts
3. Dialog: Add option and form in ContinueDialog.tsx
4. Handlers: Wire up in pages

Add New Filter

1. State: Add filter state in IdeasPage.tsx
2. UI: Add control in IdeaFilters.tsx
3. Query: Pass to listIdeas() in query key
4. Data: Handle in listIdeas() function
