Overview Aspect Details Input Project directory, platform (auto-detect or manual) Output Clean project without platform dependencies Platforms Replit, StackBlitz, CodeSandbox, Glitch Duration ~2-5 minutes Invocation Called from ln-720 (TRANSFORM mode, conditional) or user-invocable Invocation conditions: TRANSFORM mode only (SKIP in CREATE mode) At least one platform detected User confirmation before cleanup Platform Support Matrix Platform Config Files Directories NPM Packages Build Config Comments Replit .replit , replit.nix .local/ , .cache/ , .upm/ @replit/ REPL_ID checks // @replit StackBlitz .stackblitzrc .turbo/ -- Port overrides -- CodeSandbox sandbox.config.json .codesandbox/ -- CSB env checks -- Glitch glitch.json , .glitch-assets .glitch/ , .data/ -- Glitch env vars -- Reference: platform_artifacts.md Workflow Phase 1: Detect & Scan | +---> 1.0 Detect platforms (auto-detect by config files) +---> 1.1 Scan platform-specific artifacts | v Phase 2: Preview | v Phase 3: Confirm | v Phase 4: Execute (per detected platform) | +---> 4.1 Delete files/directories +---> 4.2 Modify package.json +---> 4.3 Modify build config (vite/webpack) +---> 4.4 Remove platform comments +---> 4.5 Modify .gitignore | v Phase 5: Verify & Report Phase 1: Detect & Scan Step 1.0: Platform Detection Platform Primary Indicator Confidence Replit .replit file 100% StackBlitz .stackblitzrc 100% CodeSandbox sandbox.config.json 100% Glitch glitch.json 100% Output: Detected Platforms : - replit (confidence : 100%) Step 1.1: Scan Artifacts Per detected platform, scan for artifacts using platform-specific detection rules. Replit Detection Rules: Files : - Glob : .replit , replit.nix , .replit.nix - Glob : vite - plugin - meta - images.ts (if uses REPLIT_ env vars) Directories : - Glob : .local/ , .cache/ , .upm/ , .breakpoints Package.json : - Grep : "@replit/" in devDependencies Vite Config : - Grep : "@replit/" imports - Grep : "REPL_ID" or "REPLIT_" environment checks Code : - Grep : "// @replit" comments in .tsx , .ts , .jsx , .js .gitignore : - Grep : "^.replit$" line StackBlitz/CodeSandbox/Glitch: MANDATORY READ: Load platform_artifacts.md for detection rules. Scan Output Format Scan Results : Platform : Replit Files Found : 2 - .replit (729 bytes) - vite - plugin - meta - images.ts (2333 bytes) Directories Found : 1 - .local/ (6 files , 589KB) Package Dependencies : 3 - @replit/vite - plugin - cartographer - @replit/vite - plugin - dev - banner - @replit/vite - plugin - runtime - error - modal Build Config Modifications : 4 - Import : runtimeErrorOverlay - Import : metaImagesPlugin - Plugin : runtimeErrorOverlay() - Block : REPL_ID conditional (lines 14 - 24) Code Comments : 10 - button.tsx : 5 comments - badge.tsx : 5 comments Gitignore Entries : 1 - .replit Phase 2: Preview Show detailed preview of changes per platform. Will DELETE files : - .replit (729 bytes) - vite - plugin - meta - images.ts (2333 bytes) Will DELETE directories : - .local/ (6 files , 589KB) Will MODIFY files : - package.json : Remove 3 @replit/ devDependencies - vite.config.ts : Remove 4 imports/plugins/blocks - 2 UI files : Remove 10 @replit comments - .gitignore : Remove ".replit" line Summary : 2 files deleted , 1 directory deleted , 5 files modified Phase 3: Confirm Proceed with platform cleanup (Replit)? [Y/n] Options: Y (default): Execute cleanup n: Cancel operation Custom exclusions: User can specify files to skip Phase 4: Execute Platform Router Based on detected platforms, dispatch to platform-specific cleanup. Execute sequentially if multiple platforms detected. 4.1 Replit Cleanup (Primary) Delete files/directories: rm -f .replit replit.nix .replit.nix rm -f vite-plugin-meta-images.ts rm -rf .local/ .cache/ .upm/ .breakpoints Modify package.json: Remove keys starting with @replit/ from devDependencies. Modify vite.config.ts: Remove @replit/ imports Remove Replit plugins from plugins array Remove REPL_ID conditional blocks Remove // @replit comments: Grep // @replit.$ in /*.tsx , /.ts , /.jsx , */.js . Modify .gitignore: Remove .replit line. 4.2 StackBlitz Cleanup rm -f .stackblitzrc rm -rf .turbo/

Only if not used in production

4.3 CodeSandbox Cleanup rm -f sandbox.config.json rm -rf .codesandbox/ Remove "sandbox" field from package.json (if exists). 4.4 Glitch Cleanup rm -f glitch.json .glitch-assets rm -rf .glitch/

.data/ - ASK USER before deleting (may contain important data)

Remove Glitch env var checks ( PROJECT_DOMAIN , ASSETS_URL ) from server code. Phase 5: Verify & Report Cleanup Complete ! Platforms Cleaned : Replit Deleted : - .replit - vite - plugin - meta - images.ts - .local/ (6 files) Modified : - package.json (removed 3 dependencies) - vite.config.ts (removed 4 imports/plugins) - button.tsx (removed 5 comments) - badge.tsx (removed 5 comments) - .gitignore (removed 1 line) Next Steps : 1. Run npm install to update package - lock.json 2. Run npm run build to verify build works 3. Commit : git add . && git commit -m "chore : remove platform artifacts" Edge Cases Case Handling No platform artifacts found Report "Project is clean" and exit Multiple platforms detected Clean each sequentially, separate reports Project uses Webpack (not Vite) Search webpack.config.* instead No package.json Skip NPM cleanup phase .data/ directory (Glitch) Ask user before deleting (may contain data) Error Handling Error Action Permission denied Log error, suggest chmod or admin rights File in use Retry after delay, then warn user JSON parse error Log error, suggest manual fix Build config syntax error Log error, suggest manual fix Integration With ln-720-structure-migrator Called conditionally in TRANSFORM mode: ln-720-structure-migrator : Phase 1 : Detect project type + platform Phase 2 : Clean artifacts (ln - 724 - artifact - cleaner)
