[0.1.0] - 2026-10-03

Added

  • MCP server (stdio) with ui_capture, ui_diff, ui_region, ui_assert, ui_list, ui_forget, ui_detect_dev_server.
  • Token-budgeted responses: text summary always, then region crops by area until the budget is exhausted, with explicit omission notes.
  • Pixel diff (pixelmatch) clustered into bounding-box regions with nearest-element hints.
  • Structured page summary: console errors/warnings, uncaught exceptions, failed requests, horizontal overflow, layout shifts for watched selectors, axe-core violations.
  • On-disk capture store under .ui-loop/captures/<label>/ with per-label eviction.
  • CLI: init, capture, diff, assert, list, forget, detect, hook, serve.
  • Claude Code plugin layout (.claude-plugin/, hooks/, skills/ui-loop/SKILL.md), one-plugin marketplace, and agent-plugins.org plugin.json / mcp.json.
  • PostToolUse hook for Claude Code and a best-effort Cursor afterFileEdit example.
  • Next.js App Router route inference for edited files.
