# Parameterize & Save Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Fix AI-generated scripts saving to library without parameters by adding parameter detection, user review, and template rewriting to the save flow — plus a "New from Script" paste entry point on the library page.

**Architecture:** A new `ParameterizeAndSavePanel` slide-in panel component handles two modes: `script` (pre-populated from AI builder) and `paste` (user pastes raw script). It auto-runs `detectParameterCandidates()`, renders `ParameterDetectorStepper` for review, rewrites the script body with `{{ key }}` placeholders, and sends enriched payload to the backend. Backend `save_to_library()` accepts the provided `script_body` + `parameters_schema` instead of hardcoding empty values.

**Tech Stack:** React 19, TypeScript, Tailwind CSS v4, FastAPI, Pydantic v2, SQLAlchemy 2.0

**Spec:** `docs/superpowers/specs/2026-03-29-parameterize-and-save-design.md`

### Task 1: Backend — Update `SaveToLibraryRequest` schema and `save_to_library()` service

**Files:**
- Modify: `backend/app/schemas/script_builder.py:79-84` (SaveToLibraryRequest)
- Modify: `backend/app/services/script_builder_service.py:317-377` (save_to_library function)
- Modify: `backend/app/api/endpoints/script_builder.py:156-188` (save_to_library endpoint)

- [ ] **Step 1: Update `SaveToLibraryRequest` schema**

In `backend/app/schemas/script_builder.py`, add two optional fields to `SaveToLibraryRequest`:

```python
class SaveToLibraryRequest(BaseModel):
    """Request to save a generated script to the Script Library."""
    name: str = Field(min_length=1, max_length=200)
    description: str | None = None
    category_id: UUID | None = None
    share_with_team: bool = False
    script_body: str | None = None
    parameters_schema: dict | None = None
```

- [ ] **Step 2: Update `save_to_library()` service function signature and body**

In `backend/app/services/script_builder_service.py`, add two new parameters to `save_to_library()` and use them in the `ScriptTemplate` constructor:

```python
async def save_to_library(
    db: AsyncSession,
    session: ScriptBuilderSession,
    name: str,
    description: str | None,
    category_id: UUID | None,
    share_with_team: bool,
    user_id: UUID,
    team_id: UUID | None,
    script_body: str | None = None,
    parameters_schema: dict | None = None,
) -> "ScriptTemplate":
```

And in the `ScriptTemplate(...)` constructor inside the same function, change the two hardcoded lines:

```python
    template = ScriptTemplate(
        id=uuid_mod.uuid4(),
        category_id=resolved_category_id,
        created_by=user_id,
        team_id=team_id if share_with_team else None,
        name=name,
        slug=slug,
        description=description,
        script_body=script_body or session.latest_script,
        parameters_schema=parameters_schema or {"parameters": []},
        default_values={},
        validation_rules={},
        tags=[session.language, "ai-generated"],
        complexity="intermediate",
        is_verified=False,
        is_active=True,
        version=1,
        usage_count=0,
    )
```

- [ ] **Step 3: Update the endpoint to pass new fields through**

In `backend/app/api/endpoints/script_builder.py`, update the `save_to_library` endpoint to pass the new fields to the service:

```python
        template = await script_builder_service.save_to_library(
            db=db,
            session=session,
            name=data.name,
            description=data.description,
            category_id=data.category_id,
            share_with_team=data.share_with_team,
            user_id=current_user.id,
            team_id=current_user.team_id,
            script_body=data.script_body,
            parameters_schema=data.parameters_schema,
        )
```

- [ ] **Step 4: Verify backend still starts cleanly**

Run: `cd /home/coder/resolutionflow/backend && source venv/bin/activate && python -c "from app.schemas.script_builder import SaveToLibraryRequest; print('OK')"`

Expected: `OK`

- [ ] **Step 5: Commit**

```bash
git add backend/app/schemas/script_builder.py backend/app/services/script_builder_service.py backend/app/api/endpoints/script_builder.py
git commit -m "feat: accept script_body and parameters_schema in save-to-library flow

Previously save_to_library() hardcoded parameters_schema to empty and
always used session.latest_script. Now accepts optional overrides from
the frontend for parameterized script bodies.

### Task 2: Frontend — Update `SaveToLibraryRequest` type

**Files:**
- Modify: `frontend/src/types/script-builder.ts:45-50` (SaveToLibraryRequest interface)

- [ ] **Step 1: Add new fields to the TypeScript interface**

In `frontend/src/types/script-builder.ts`, update `SaveToLibraryRequest`:

```typescript
export interface SaveToLibraryRequest {
  name: string
  description?: string
  category_id?: string
  share_with_team?: boolean
  script_body?: string
  parameters_schema?: { parameters: ScriptParameter[] }
}
```

Add the import for `ScriptParameter` at the top of the file:

```typescript
import type { ScriptParameter } from './scripts'
```

- [ ] **Step 2: Verify types compile**

Run: `cd /home/coder/resolutionflow/frontend && npx tsc --noEmit --pretty 2>&1 | head -30`

Expected: No errors related to `SaveToLibraryRequest` or `ScriptParameter`.

- [ ] **Step 3: Commit**

```bash
git add frontend/src/types/script-builder.ts
git commit -m "feat: add script_body and parameters_schema to SaveToLibraryRequest type

```

### Task 3: Frontend — Create `ParameterizeAndSavePanel` component

**Files:**
- Create: `frontend/src/components/scripts/ParameterizeAndSavePanel.tsx`

This is the core new component. It handles two modes (`script` and `paste`), auto-runs parameter detection, embeds the existing `ParameterDetectorStepper`, rewrites the script body with `{{ key }}` placeholders, collects metadata, and calls the save handler.

- [ ] **Step 1: Create the component file**

Create `frontend/src/components/scripts/ParameterizeAndSavePanel.tsx`:

- [ ] **Step 2: Verify the component compiles**

Run: `cd /home/coder/resolutionflow/frontend && npx tsc --noEmit --pretty 2>&1 | head -30`

Expected: No errors in `ParameterizeAndSavePanel.tsx`.

- [ ] **Step 3: Commit**

```bash
git add frontend/src/components/scripts/ParameterizeAndSavePanel.tsx
git commit -m "feat: add ParameterizeAndSavePanel component

Slide-in panel for saving scripts to library with parameter detection,
stepper review, template rewriting, and metadata collection. Supports
both script mode (from AI builder) and paste mode (raw script import).

### Task 4: Frontend — Wire `ParameterizeAndSavePanel` into `ScriptBuilderPage`

**Files:**
- Modify: `frontend/src/pages/ScriptBuilderPage.tsx`

Replace the `SaveToLibraryDialog` import and usage with `ParameterizeAndSavePanel`.

- [ ] **Step 1: Update imports**

In `frontend/src/pages/ScriptBuilderPage.tsx`, replace the `SaveToLibraryDialog` import:

```typescript
// REMOVE this line:
import { SaveToLibraryDialog } from '@/components/script-builder/SaveToLibraryDialog'

// ADD this line:
import { ParameterizeAndSavePanel } from '@/components/scripts/ParameterizeAndSavePanel'
```

Also add `scriptBuilderApi` to the existing import if not already there (it is already imported on line 8):

```typescript
import { scriptBuilderApi } from '@/api'
```

- [ ] **Step 2: Add the save handler function**

Inside the `ScriptBuilderPage` component, replace `handleSaved`:

```typescript
  const handleSaved = async (payload: {
    name: string
    description: string | undefined
    category_id: string | undefined
    share_with_team: boolean
    script_body: string
    parameters_schema: { parameters: import('@/types').ScriptParameter[] }
  }) => {
    if (!session) return
    await scriptBuilderApi.saveToLibrary(session.id, {
      name: payload.name,
      description: payload.description,
      category_id: payload.category_id,
      share_with_team: payload.share_with_team,
      script_body: payload.script_body,
      parameters_schema: payload.parameters_schema,
    })
    setShowSaveDialog(false)
  }
```

- [ ] **Step 3: Replace the dialog JSX with the panel**

Replace the `SaveToLibraryDialog` JSX block (lines 194-200) with:

```tsx
      {/* Save panel */}
      {showSaveDialog && session && session.latest_script && (
        <ParameterizeAndSavePanel
          scriptBody={session.latest_script}
          language={session.language}
          defaultName={defaultSaveName}
          onSave={handleSaved}
          onClose={() => setShowSaveDialog(false)}
        />
      )}
```

- [ ] **Step 4: Verify it compiles**

Run: `cd /home/coder/resolutionflow/frontend && npx tsc --noEmit --pretty 2>&1 | head -30`

Expected: No type errors.

- [ ] **Step 5: Commit**

```bash
git add frontend/src/pages/ScriptBuilderPage.tsx
git commit -m "feat: wire ParameterizeAndSavePanel into ScriptBuilderPage

Replace SaveToLibraryDialog with the new panel that includes parameter
detection, review, and template rewriting before saving to library.

```

### Task 5: Frontend — Add "New from Script" button to `ScriptLibraryPage`

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

- [ ] **Step 1: Add imports**

Add these imports to the top of `ScriptLibraryPage.tsx`:

```typescript
import { FileUp } from 'lucide-react'
import { ParameterizeAndSavePanel } from '@/components/scripts/ParameterizeAndSavePanel'
import { scriptsApi } from '@/api'
import type { ScriptParameter } from '@/types'
```

Update the existing lucide import to include `FileUp` alongside `Terminal`, `Settings`, `Wand2`:

```typescript
import { Terminal, Settings, Wand2, FileUp } from 'lucide-react'
```

- [ ] **Step 2: Add state and handler for the import panel**

Inside `ScriptLibraryPage`, add state and a save handler:

```typescript
  const [showImportPanel, setShowImportPanel] = useState(false)

  const handleImportSave = async (payload: {
    name: string
    description: string | undefined
    category_id: string | undefined
    share_with_team: boolean
    script_body: string
    parameters_schema: { parameters: ScriptParameter[] }
  }) => {
    // createTemplate requires category_id — if user didn't pick one,
    // fall back to the first available category
    const categoryId = payload.category_id || categories[0]?.id
    if (!categoryId) {
      throw new Error('No categories available. Please create a category first.')
    }
    await scriptsApi.createTemplate({
      category_id: categoryId,
      name: payload.name,
      description: payload.description,
      script_body: payload.script_body,
      parameters_schema: payload.parameters_schema,
    })
    setShowImportPanel(false)
    // Reload templates to show the newly created one
    const filters = activeTab === 'mine' ? { mine: true } : { shared: true }
    loadTemplates(filters)
  }
```

Note: `categories` needs to be read from the store. Add this line alongside the other store selectors:

```typescript
  const categories = useScriptGeneratorStore(s => s.categories)
```

- [ ] **Step 3: Add the "New from Script" button**

In the page header section, next to the "Manage Templates" link, add:

```tsx
          {isEngineer && (
            <div className="flex items-center gap-2 mt-2">
              <Link
                to="/scripts/manage"
                className="inline-flex items-center gap-1.5 text-xs text-primary bg-accent-dim hover:bg-primary/15 px-2.5 py-1 rounded-full transition-colors group"
              >
                <Settings size={12} className="group-hover:rotate-90 transition-transform duration-300" />
                Manage Templates
              </Link>
              <button
                type="button"
                onClick={() => setShowImportPanel(true)}
                className="inline-flex items-center gap-1.5 text-xs text-primary bg-accent-dim hover:bg-primary/15 px-2.5 py-1 rounded-full transition-colors"
              >
                <FileUp size={12} />
                New from Script
              </button>
            </div>
          )}
```

This replaces the existing `{isEngineer && (...)}` block that only had the Manage Templates link.

- [ ] **Step 4: Add the panel JSX**

At the end of the component return, before the closing `</div>`, add:

```tsx
      {/* Import script panel */}
      {showImportPanel && (
        <ParameterizeAndSavePanel
          onSave={handleImportSave}
          onClose={() => setShowImportPanel(false)}
        />
      )}
```

- [ ] **Step 5: Verify it compiles**

Run: `cd /home/coder/resolutionflow/frontend && npx tsc --noEmit --pretty 2>&1 | head -30`

Expected: No type errors.

- [ ] **Step 6: Commit**

```bash
git add frontend/src/pages/ScriptLibraryPage.tsx
git commit -m "feat: add 'New from Script' button to ScriptLibraryPage

Opens the ParameterizeAndSavePanel in paste mode, letting users import
raw scripts with parameter detection and review before saving to library.

### Task 6: Frontend — Delete `SaveToLibraryDialog` and clean up imports

**Files:**
- Delete: `frontend/src/components/script-builder/SaveToLibraryDialog.tsx`

- [ ] **Step 1: Verify no other files import `SaveToLibraryDialog`**

Run: `grep -r "SaveToLibraryDialog" frontend/src/ --include="*.ts" --include="*.tsx" | grep -v "node_modules"`

Expected: No results (ScriptBuilderPage was updated in Task 4).

- [ ] **Step 2: Delete the file**

```bash
rm frontend/src/components/script-builder/SaveToLibraryDialog.tsx
```

- [ ] **Step 3: Run full build check**

Run: `cd /home/coder/resolutionflow/frontend && npm run build 2>&1 | tail -20`

Expected: Build succeeds with no errors. This is the strictest check (`tsc -b` enforces `noUnusedLocals`).

- [ ] **Step 4: Commit**

```bash
git add -u frontend/src/components/script-builder/SaveToLibraryDialog.tsx
git commit -m "chore: delete SaveToLibraryDialog, replaced by ParameterizeAndSavePanel

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>"
```

---

### Task 7: Full build verification and final commit

**Files:** None (verification only)

- [ ] **Step 1: Run frontend build**

Run: `cd /home/coder/resolutionflow/frontend && npm run build 2>&1 | tail -20`

Expected: Build succeeds. This catches any `noUnusedLocals`/`noUnusedParameters` errors the earlier `tsc --noEmit` might miss.

- [ ] **Step 2: Verify backend imports are clean**

Run: `cd /home/coder/resolutionflow/backend && source venv/bin/activate && python -c "from app.api.endpoints.script_builder import router; print('OK')"`

Expected: `OK`

- [ ] **Step 3: Verify git status is clean**

Run: `git status`

Expected: On branch `feat/task-lane-persistence`, working tree clean (all changes committed in Tasks 1-6).
