# Script Template Editor — Implementation Plan

> **For Claude:** REQUIRED: Use superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Build a Script Template Editor page (`/scripts/manage`) where engineers create personal templates, owners/admins can edit any and toggle "Share with team", and super admins have full access.

**Architecture:** Refactor backend permission checks on existing CRUD endpoints to allow engineers to manage their own templates. Add `PATCH /share` endpoint. Build a new frontend page with list/editor modes, a visual parameter schema builder with JSON toggle, and a PowerShell script body editor.

**Tech Stack:** Python FastAPI, SQLAlchemy 2.0, Pydantic v2, React 19, TypeScript, Zustand, Axios (`apiClient`), Tailwind CSS v3, Lucide React.

## Chunk 1: Backend — Permission Refactor + Share Endpoint

### Task 1: Add `can_manage_script_template` to permissions.py

**Files:**
- Modify: `backend/app/core/permissions.py`

- [ ] **Step 1: Add the permission function**

Add at the end of `backend/app/core/permissions.py`:

```python
def can_manage_script_template(user: User, template_created_by: Optional[UUID], template_account_id: Optional[UUID] = None) -> bool:
    """Can the user edit/delete this script template?

    - Super admins can manage any template
    - Account owners can manage any template in their account
    - Engineers can manage templates they created
    """
    if user.is_super_admin:
        return True
    if user.account_role == "owner" and template_account_id == user.account_id and user.account_id is not None:
        return True
    if template_created_by == user.id:
        return True
    return False
```

Add the import at the top if not present:
```python
from uuid import UUID
```

- [ ] **Step 2: Verify no import errors**

```bash
docker exec resolutionflow_backend python -c "from app.core.permissions import can_manage_script_template; print('OK')"
```
Expected: `OK`

- [ ] **Step 3: Commit**

```bash
git add backend/app/core/permissions.py
git commit -m "feat: add can_manage_script_template permission check

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```

---

### Task 2: Add `created_by` to response schemas

**Files:**
- Modify: `backend/app/schemas/script_template.py`

- [ ] **Step 1: Add `created_by` field to `ScriptTemplateListItem`**

In `backend/app/schemas/script_template.py`, add `created_by` to `ScriptTemplateListItem` (line ~82, after `team_id`):

```python
class ScriptTemplateListItem(BaseModel):
    id: UUID
    category_id: UUID
    team_id: Optional[UUID] = None
    created_by: Optional[UUID] = None      # ← ADD THIS LINE
    name: str
    slug: str
    # ... rest stays the same
```

- [ ] **Step 2: Verify import works**

```bash
docker exec resolutionflow_backend python -c "from app.schemas.script_template import ScriptTemplateListItem; print(ScriptTemplateListItem.model_fields.keys())"
```
Expected: output includes `created_by`

- [ ] **Step 3: Commit**

```bash
git add backend/app/schemas/script_template.py
git commit -m "feat: expose created_by in script template response schemas

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```

---

### Task 3: Refactor script endpoint permissions

**Files:**
- Modify: `backend/app/api/endpoints/scripts.py`

- [ ] **Step 1: Replace `_require_team_admin` with new permission logic**

In `backend/app/api/endpoints/scripts.py`:

1. Remove the `_require_team_admin` function (lines 30-36).

2. Add these imports at the top:
```python
from app.core.permissions import can_manage_script_template, can_create_content
```

3. Replace the `create_template` endpoint permission check. Change:
```python
_require_team_admin(current_user)
```
to:
```python
if not can_create_content(current_user):
    raise HTTPException(
        status_code=status.HTTP_403_FORBIDDEN,
        detail="Engineer access required to create templates",
    )
```

4. Replace the `update_template` endpoint. Change the permission check AND the query. The current query filters by `team_id == current_user.team_id` which is too restrictive. Replace the full endpoint:

```python
@router.put("/templates/{template_id}", response_model=ScriptTemplateDetail)
async def update_template(
    template_id: UUID,
    data: ScriptTemplateUpdate,
    db: Annotated[AsyncSession, Depends(get_db)],
    current_user: Annotated[User, Depends(get_current_active_user)],
) -> ScriptTemplateDetail:
    result = await db.execute(
        select(ScriptTemplate).where(
            ScriptTemplate.id == template_id,
            ScriptTemplate.is_active == True,  # noqa: E712
        )
    )
    template = result.scalar_one_or_none()
    if not template:
        raise HTTPException(
            status_code=status.HTTP_404_NOT_FOUND,
            detail="Template not found",
        )

    if not can_manage_script_template(current_user, template.created_by, template.team_id):
        raise HTTPException(
            status_code=status.HTTP_403_FORBIDDEN,
            detail="You don't have permission to edit this template",
        )

    update_data = data.model_dump(exclude_unset=True)
    if "script_body" in update_data or "parameters_schema" in update_data:
        template.version += 1
    for field, value in update_data.items():
        setattr(template, field, value)

    await db.commit()
    await db.refresh(template)
    return ScriptTemplateDetail.model_validate(template)
```

5. Replace the `delete_template` endpoint similarly:

```python
@router.delete("/templates/{template_id}", status_code=status.HTTP_204_NO_CONTENT)
async def delete_template(
    template_id: UUID,
    db: Annotated[AsyncSession, Depends(get_db)],
    current_user: Annotated[User, Depends(get_current_active_user)],
) -> None:
    result = await db.execute(
        select(ScriptTemplate).where(
            ScriptTemplate.id == template_id,
            ScriptTemplate.is_active == True,  # noqa: E712
        )
    )
    template = result.scalar_one_or_none()
    if not template:
        raise HTTPException(
            status_code=status.HTTP_404_NOT_FOUND,
            detail="Template not found",
        )

    if not can_manage_script_template(current_user, template.created_by, template.team_id):
        raise HTTPException(
            status_code=status.HTTP_403_FORBIDDEN,
            detail="You don't have permission to delete this template",
        )

    template.is_active = False
    await db.commit()
```

- [ ] **Step 2: Add `managed` query param to `list_templates`**

In the `list_templates` endpoint, add a new query parameter and filter. Add after the existing `tags` param:

```python
managed: Optional[bool] = Query(None, description="If true, return only templates this user can edit"),
```

Add this filter block after the existing `search` filter (before executing the query):

```python
if managed:
    if current_user.is_super_admin:
        pass  # super admin can edit all
    elif current_user.account_role == "owner":
        # owners see account-scoped templates
        query = query.where(
            or_(
                ScriptTemplate.created_by == current_user.id,
                ScriptTemplate.team_id != None,  # noqa: E711
            )
        )
    else:
        # engineers see only their own
        query = query.where(ScriptTemplate.created_by == current_user.id)
```

- [ ] **Step 3: Add the share endpoint**

Add at the end of `backend/app/api/endpoints/scripts.py` (before the generations section):

```python
@router.patch("/templates/{template_id}/share", response_model=ScriptTemplateDetail)
async def share_template(
    template_id: UUID,
    db: Annotated[AsyncSession, Depends(get_db)],
    current_user: Annotated[User, Depends(get_current_active_user)],
    shared: bool = Query(..., description="true to share with team, false to make personal"),
) -> ScriptTemplateDetail:
    """Toggle team sharing for a template. Owner/admin/super_admin only."""
    if not (current_user.is_super_admin or current_user.account_role == "owner"):
        raise HTTPException(
            status_code=status.HTTP_403_FORBIDDEN,
            detail="Only account owners and admins can share templates",
        )

    result = await db.execute(
        select(ScriptTemplate).where(
            ScriptTemplate.id == template_id,
            ScriptTemplate.is_active == True,  # noqa: E712
        )
    )
    template = result.scalar_one_or_none()
    if not template:
        raise HTTPException(
            status_code=status.HTTP_404_NOT_FOUND,
            detail="Template not found",
        )

    if shared:
        template.team_id = current_user.team_id
    else:
        template.team_id = None

    await db.commit()
    await db.refresh(template)
    return ScriptTemplateDetail.model_validate(template)
```

- [ ] **Step 4: Verify the backend starts**

```bash
docker compose -f docker-compose.dev.yml restart backend && sleep 3 && curl -s http://localhost:8000/api/docs | head -5
```
Expected: Backend starts without import errors.

- [ ] **Step 5: Commit**

```bash
git add backend/app/api/endpoints/scripts.py
git commit -m "feat: refactor script template permissions — engineers manage own, add /share endpoint

## Chunk 2: Frontend — Types, API Client, Permissions

### Task 5: Extend frontend types

**Files:**
- Modify: `frontend/src/types/scripts.ts`

- [ ] **Step 1: Add `created_by` to `ScriptTemplateListItem`**

In `frontend/src/types/scripts.ts`, add `created_by` after the `team_id` field in `ScriptTemplateListItem`:

```typescript
created_by: string | null
```

- [ ] **Step 2: Add create/update request interfaces**

Add at the end of `frontend/src/types/scripts.ts`:

```typescript
export interface ScriptTemplateCreateRequest {
  category_id: string
  name: string
  description?: string | null
  use_case?: string | null
  script_body: string
  parameters_schema: ScriptParametersSchema
  tags?: string[]
  complexity?: 'beginner' | 'intermediate' | 'advanced'
  estimated_runtime?: string | null
  requires_elevation?: boolean
  requires_modules?: string[]
}

export interface ScriptTemplateUpdateRequest {
  name?: string
  description?: string | null
  use_case?: string | null
  script_body?: string
  parameters_schema?: ScriptParametersSchema
  tags?: string[]
  complexity?: 'beginner' | 'intermediate' | 'advanced'
  estimated_runtime?: string | null
  requires_elevation?: boolean
  requires_modules?: string[]
}
```

- [ ] **Step 3: Verify build**

```bash
docker exec resolutionflow_frontend npm run build 2>&1 | tail -10
```
Expected: no errors.

- [ ] **Step 4: Commit**

```bash
git add frontend/src/types/scripts.ts
git commit -m "feat: add created_by and create/update request types for script templates

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```

---

### Task 6: Extend API client

**Files:**
- Modify: `frontend/src/api/scripts.ts`

- [ ] **Step 1: Add CRUD + share methods to `scriptsApi`**

Add the following imports to the top of `frontend/src/api/scripts.ts`:

```typescript
import type {
  ScriptCategoryResponse,
  ScriptTemplateListItem,
  ScriptTemplateDetail,
  ScriptGenerateRequest,
  ScriptGenerateResponse,
  ScriptGenerationRecord,
  ScriptTemplateCreateRequest,
  ScriptTemplateUpdateRequest,
} from '@/types'
```

Add these methods inside the `scriptsApi` object (before the closing `}`):

```typescript
  async getManagedTemplates(params?: {
    category_slug?: string
    search?: string
  }): Promise<ScriptTemplateListItem[]> {
    const response = await apiClient.get<ScriptTemplateListItem[]>('/scripts/templates', {
      params: { ...params, managed: true },
    })
    return response.data
  },

  async createTemplate(data: ScriptTemplateCreateRequest): Promise<ScriptTemplateDetail> {
    const response = await apiClient.post<ScriptTemplateDetail>('/scripts/templates', data)
    return response.data
  },

  async updateTemplate(id: string, data: ScriptTemplateUpdateRequest): Promise<ScriptTemplateDetail> {
    const response = await apiClient.put<ScriptTemplateDetail>(`/scripts/templates/${id}`, data)
    return response.data
  },

  async deleteTemplate(id: string): Promise<void> {
    await apiClient.delete(`/scripts/templates/${id}`)
  },

  async shareTemplate(id: string, shared: boolean): Promise<ScriptTemplateDetail> {
    const response = await apiClient.patch<ScriptTemplateDetail>(
      `/scripts/templates/${id}/share`,
      null,
      { params: { shared } },
    )
    return response.data
  },
```

- [ ] **Step 2: Verify build**

```bash
docker exec resolutionflow_frontend npm run build 2>&1 | tail -10
```
Expected: no errors.

- [ ] **Step 3: Commit**

```bash
git add frontend/src/api/scripts.ts
git commit -m "feat: add CRUD and share methods to scriptsApi client

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```

---

### Task 7: Add permission check to usePermissions

**Files:**
- Modify: `frontend/src/hooks/usePermissions.ts`

- [ ] **Step 1: Add `canManageScriptTemplate` to the returned object**

In `frontend/src/hooks/usePermissions.ts`, add inside the returned object (after `canManageGlobalCategories`):

```typescript
    canManageScriptTemplate: (template: { created_by: string | null; team_id?: string | null }) => {
      if (!user) return false
      if (user.is_super_admin) return true
      if (user.account_role === 'owner') return true
      return template.created_by === user.id
    },

    canShareScriptTemplate: effectiveRole === 'super_admin' || effectiveRole === 'owner',

    canCreateScriptTemplate: hasMinimumRole(user, 'engineer'),
```

- [ ] **Step 2: Verify build**

```bash
docker exec resolutionflow_frontend npm run build 2>&1 | tail -10
```
Expected: no errors.

- [ ] **Step 3: Commit**

```bash
git add frontend/src/hooks/usePermissions.ts
git commit -m "feat: add script template permission checks to usePermissions hook

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```

### Task 13: ScriptManagePage + Routing

**Files:**
- Create: `frontend/src/pages/ScriptManagePage.tsx`
- Modify: `frontend/src/router.tsx`
- Modify: `frontend/src/pages/ScriptLibraryPage.tsx`

- [ ] **Step 1: Create `frontend/src/pages/ScriptManagePage.tsx`**

```tsx
import { useState } from 'react'
import { ScriptTemplateListView } from '@/components/script-editor/ScriptTemplateListView'
import { ScriptTemplateEditor } from '@/components/script-editor/ScriptTemplateEditor'

export default function ScriptManagePage() {
  const [mode, setMode] = useState<'list' | 'edit'>('list')
  const [editingId, setEditingId] = useState<string | null>(null)

  const handleEdit = (id: string) => {
    setEditingId(id)
    setMode('edit')
  }

  const handleCreate = () => {
    setEditingId(null)
    setMode('edit')
  }

  const handleBack = () => {
    setEditingId(null)
    setMode('list')
  }

  const handleSaved = () => {
    setEditingId(null)
    setMode('list')
  }

  return (
    <div className="p-6 max-w-5xl mx-auto">
      {mode === 'list' ? (
        <ScriptTemplateListView onEdit={handleEdit} onCreate={handleCreate} />
      ) : (
        <ScriptTemplateEditor
          templateId={editingId}
          onBack={handleBack}
          onSaved={handleSaved}
        />
      )}
    </div>
  )
}
```

- [ ] **Step 2: Add lazy import and route to `frontend/src/router.tsx`**

After the `ScriptLibraryPage` import (line 44), add:

```typescript
const ScriptManagePage = lazy(() => import('@/pages/ScriptManagePage'))
```

In the protected/AppLayout children array, after the `scripts` route (line 164), add:

```typescript
{ path: 'scripts/manage', element: page(ScriptManagePage) },
```

- [ ] **Step 3: Add "Manage Templates" link to `ScriptLibraryPage.tsx`**

In `frontend/src/pages/ScriptLibraryPage.tsx`, add these imports at the top:

```typescript
import { Link } from 'react-router-dom'
import { Settings } from 'lucide-react'
```

Then in the page header `<div>` (after the `<p>` subtitle, around line 51), add:

```tsx
        {isEngineer && (
          <Link
            to="/scripts/manage"
            className="inline-flex items-center gap-1.5 text-xs text-muted-foreground hover:text-foreground transition-colors mt-2"
          >
            <Settings size={12} />
            Manage Templates
          </Link>
        )}
```

Note: `isEngineer` is already destructured from `usePermissions()` on the existing line 22.

- [ ] **Step 4: Verify build**

```bash
docker exec resolutionflow_frontend npm run build 2>&1 | tail -20
```
Expected: clean build, no errors.

- [ ] **Step 5: Commit**

```bash
git add frontend/src/pages/ScriptManagePage.tsx frontend/src/router.tsx frontend/src/pages/ScriptLibraryPage.tsx
git commit -m "feat: add ScriptManagePage with routing and 'Manage Templates' link

## Chunk 7: Smoke Test

### Task 14: End-to-End Smoke Test

- [ ] **Step 1: Rebuild containers**

```bash
docker compose -f docker-compose.dev.yml up -d --build backend frontend
```

- [ ] **Step 2: Verify backend tests pass**

```bash
docker exec resolutionflow_backend pytest tests/test_script_templates.py -v
```
Expected: All tests pass.

- [ ] **Step 3: Verify frontend build**

```bash
docker exec resolutionflow_frontend npm run build 2>&1 | tail -20
```
Expected: Clean build.

- [ ] **Step 4: Manual smoke test checklist**

Open http://localhost:5173 and log in as `engineer@resolutionflow.example.com` (`TestPass123!`).

1. Navigate to Script Library → click "Manage Templates" link
2. Page loads at `/scripts/manage` with empty list (or existing templates)
3. Click "New Template" → editor form appears
4. Fill in: name, category, script body with `{{ param }}` placeholder, add a parameter via visual builder
5. Click "Create Template" → redirects to list, new template appears
6. Click Edit on the template → form pre-fills correctly
7. Toggle to JSON mode in parameters → JSON appears, edit, toggle back → syncs
8. Click "Save Changes" → success
9. Click Delete → confirm → template removed from list
10. Verify "Share with team" toggle is NOT visible (engineer role)

Then log in as `admin@resolutionflow.example.com` and verify:
11. "Share with team" toggle IS visible on edit form
12. Toggle share on → scope badge changes to "Team"
13. Toggle share off → reverts to "Personal"

- [ ] **Step 5: Commit confirmation**

```bash
git add -A
git commit -m "chore: script template editor smoke test complete
