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) # CONDITIONAL Condition: Platform detected (Replit/StackBlitz/CodeSandbox/Glitch) Skipped if: CREATE mode OR no platform markers Phase 3: Restructure frontend (ln-721) Phase 4: Generate backend (ln-722) Phase 5: Generate seed data (ln-723)

Standalone Usage

User: Clean my project from platform artifacts Claude: Invokes ln-724-artifact-cleaner

Critical Rules

• Conditional Invocation: Only run when platform artifacts detected, SKIP in CREATE mode

• User Confirmation: Always preview and confirm before deleting

• No Data Loss: Ask user before deleting directories that may contain user data (.data/)

• Build Verification: Recommend npm run build after cleanup

• Idempotent: Re-running on clean project reports "no artifacts found"

References

• platform_artifacts.md - Per-platform artifact catalog

Definition of Done

• At least one platform detected (Replit/StackBlitz/CodeSandbox/Glitch)

• All platform artifacts scanned and previewed to user

• User confirmation received before any deletions

• Platform files, directories, dependencies, build config, and comments cleaned

• .gitignore entries for platform files removed

• Cleanup report generated with deleted/modified file counts
