+# WDS Installer Fixes — 2026-02-23
+
+**Priority:** URGENT (workshop in 1 hour)
+**Fixed by:** Claude Code + Marten Angner
+**File:** `tools/cli/lib/installer.js`
+
+---
+
+## Issues Fixed
+
+### 1. Detects Existing Deliverables Folder ✓
+
+**Problem:** Installer always created `docs/` folder, even if user had `design-process/` or other folder with existing work.
+
+**Fix:**
+- `createDocsFolders()` now checks for existing folders: `design-process`, `docs`, `deliverables`, `wds-deliverables`
+- Detects WDS structure by looking for `A-Product-Brief/` or `B-Trigger-Map/`
+- Uses existing folder if found
+- Only creates `docs/` if no existing structure detected
+
+### 2. Updates config.yaml with Detected Folder ✓
+
+**Problem:** `config.yaml` hardcoded `output_folder: docs` regardless of actual folder.
+
+**Fix:**
+- Installer now returns the detected folder name from `createDocsFolders()`
+- Updates `config.yaml` to match: `output_folder: design-process` (or whatever was detected)
+- Agents read correct path from config
+
+### 3. Never Overwrites Existing Files ✓
+
+**Problem:** Installer created `.gitkeep` files in folders, potentially overwriting user content.
+
+**Fix:**
+- Checks if folder exists before creating it (`fs.pathExists`)
+- Checks if folder is empty before adding `.gitkeep`
+- Never overwrites existing user files
+
+### 4. Copies 00 Guide Files to Folders ✓
+
+**Problem:** Templates existed in `src/workflows/0-project-setup/templates/folder-guides/` but were never copied to phase folders during installation.
+
+**Fix:**
+- Implemented `createFolderGuides()` method to copy all 00 templates:
+  - `00-product-brief.md` → A-Product-Brief/
+  - `00-trigger-map.md` → B-Trigger-Map/
+  - `00-ux-scenarios.md` → C-UX-Scenarios/
+  - `00-design-system.md` → D-Design-System/
+- Replaces placeholders ({{project_name}}, {{date}}, {{user_name}}, etc.)
+- Also creates `00-project-info.md` in A-Product-Brief (project settings home)
+- Never overwrites existing files
+
+---
+
+## Code Changes
+
+### Modified Function: `createDocsFolders(projectDir)`
+
+**Before:**
+```javascript
+async createDocsFolders(projectDir) {
+  const docsPath = path.join(projectDir, 'docs');  // Hardcoded!
+  // ...always created docs/
+}
+```
+
+**After:**
+```javascript
+async createDocsFolders(projectDir) {
+  // Detect existing folder first
+  const possibleFolders = ['design-process', 'docs', 'deliverables', 'wds-deliverables'];
+  let existingFolder = null;
+
+  for (const folderName of possibleFolders) {
+    const folderPath = path.join(projectDir, folderName);
+    if (await fs.pathExists(folderPath)) {
+      const hasProductBrief = await fs.pathExists(path.join(folderPath, 'A-Product-Brief'));
+      const hasTriggerMap = await fs.pathExists(path.join(folderPath, 'B-Trigger-Map'));
+      if (hasProductBrief || hasTriggerMap) {
+        existingFolder = folderName;
+        break;
+      }
+    }
+  }
+
+  const outputFolder = existingFolder || 'docs';
+  // ...
+  return outputFolder;  // Return for config.yaml update
+}
+```
+
+### Modified: install() method
+
+Added config.yaml update after folder detection:
+
+```javascript
+// Update config.yaml with detected output folder
+if (detectedOutputFolder !== 'docs') {
+  const configPath = path.join(wdsDir, 'config.yaml');
+  let configContent = await fs.readFile(configPath, 'utf8');
+  configContent = configContent.replace(/output_folder:\s*docs/, `output_folder: ${detectedOutputFolder}`);
+  await fs.writeFile(configPath, configContent, 'utf8');
+}
+```
+
+### Added: createFolderGuides() method
+
+New method copies 00 guide templates to folders:
+
+```javascript
+async createFolderGuides(docsPath, config) {
+  const templateDir = path.join(this.srcDir, 'workflows', '0-project-setup', 'templates', 'folder-guides');
+
+  const guides = [
+    { template: '00-product-brief.template.md', folder: 'A-Product-Brief', filename: '00-product-brief.md' },
+    { template: '00-trigger-map.template.md', folder: 'B-Trigger-Map', filename: '00-trigger-map.md' },
+    { template: '00-ux-scenarios.template.md', folder: 'C-UX-Scenarios', filename: '00-ux-scenarios.md' },
+    { template: '00-design-system.template.md', folder: 'D-Design-System', filename: '00-design-system.md' },
+  ];
+
+  const replacements = { /* project_name, date, user_name, etc. */ };
+
+  for (const guide of guides) {
+    const templatePath = path.join(templateDir, guide.template);
+    const destPath = path.join(docsPath, guide.folder, guide.filename);
+
+    if (await fs.pathExists(destPath)) continue;  // Never overwrite
+    if (!(await fs.pathExists(templatePath))) continue;
+
+    let content = await fs.readFile(templatePath, 'utf8');
+    for (const [placeholder, value] of Object.entries(replacements)) {
+      content = content.split(placeholder).join(value);
+    }
+    await fs.writeFile(destPath, content, 'utf8');
+  }
+
+  await this.createProjectInfoFile(docsPath, config);  // Also create project info
+}
+```
+
+---
+
+## Testing
+
+### Before Fix:
+```bash
+cd existing-project-with-design-process/
+npx whiteport-design-studio install
+# Result: Created docs/A-Product-Brief/, docs/B-Trigger-Map/, etc.
+# config.yaml: output_folder: docs
+# Agents read from wrong folder!
+```
+
+### After Fix:
+```bash
+cd existing-project-with-design-process/
+npx whiteport-design-studio install
+# Result: Detected design-process/ folder
+# No new folders created (design-process/ already has A-Product-Brief/, B-Trigger-Map/)
+# config.yaml: output_folder: design-process
+# Agents read from correct folder!
+```
+
+---
+
+## Workshop Readiness
+
+**Status:** ✅ Ready
+
+Installer now:
+1. ✅ Respects existing folder structure (design-process/, docs/, deliverables/, wds-deliverables/)
+2. ✅ Never overwrites user files (checks fs.pathExists before all writes)
+3. ✅ Configures agents to read from correct location (updates config.yaml output_folder)
+4. ✅ Shows detected folder in spinner message
+5. ✅ Copies all 00 guide files to phase folders (Product Brief, Trigger Map, UX Scenarios, Design System)
+6. ✅ Creates 00-project-info.md with project settings in A-Product-Brief
+
+**Critical files installed:**
+- `A-Product-Brief/00-product-brief.md` (folder guide)
+- `A-Product-Brief/00-project-info.md` (project settings home)
+- `B-Trigger-Map/00-trigger-map.md` (folder guide)
+- `C-UX-Scenarios/00-ux-scenarios.md` (folder guide)
+- `D-Design-System/00-design-system.md` (folder guide)
+
+---
+
+## Next Steps (Post-Workshop)
+
+1. Add UI prompt to let user choose output folder during install
+2. Add validation to ensure folder structure is WDS-compatible
+3. Consider migrating old `docs/` to `design-process/` if user wants
+4. Add tests for folder detection logic
+
