Task Completion Log: Decompose Agent

Date: 2026-02-20 Agent: decompose-agent Status: Completed

Summary

Successfully decomposed js/ui/components/VideoModal.js by extracting distinct functional blocks into separate controllers. This improved code organization and reduced the file size significantly.

Decomposition Details

• Source File: js/ui/components/VideoModal.js (Lines before: 6045)
• Extracted Controllers:
  1. js/ui/components/video-modal/zapController.js: Encapsulates all Zap dialog logic (popover, form, receipts, visibility).
  2. js/ui/components/video-modal/linkPreviewController.js: Encapsulates link preview fetching and rendering logic.
• Lines Reduced: 1069 (New size: 4976 lines)

Bug Fixes

• Addressed code review feedback: Updated ZapController and LinkPreviewController to access document and window dynamically from the modal instance to avoid initialization timing issues.

Verification

• Lint: Passed (npm run lint).
• Unit Tests: Passed (npm run test:unit).
• Baseline: Updated scripts/check-file-size.mjs with new line count for js/ui/components/VideoModal.js.

Artifacts

• context/CONTEXT_2026-02-20_decompose-agent.md: Detailed plan and rationale.
• New files: js/ui/components/video-modal/zapController.js, js/ui/components/video-modal/linkPreviewController.js.
