Phase 1: Detect & Scan

Step 1.0: Platform Detection

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"

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
