Summary

Add FableCut 0.1.0 as a ready-to-install MiniMax Code Mini App under plugins/klarkxy/fablecut/, and list it in both root READMEs.

The package vendors FableCut 1.16.0 at fd2af081d73ec94464b88df8c21f640adcc78985, including the timeline editor, 19 upstream MCP tools and a project-folder import tool. It runs on the Host-assigned HTTP listener, stores projects and media in context.dataDir, and includes an editing Skill with optional Agent-side media generation through mcode-tools. MIT attribution, font licenses, upstream provenance and local adaptations are included.

The port isolates Agent file capabilities from page requests, guards stale project writes, saves a version before replacing a project during import, and owns media subprocess cleanup. Rendering uses the open editor tab; there is no external headless-browser fallback. FFmpeg and FFprobe must be installed separately.

Validation

Environment: Windows 11 x64, Node.js 26.10.0, FFmpeg/FFprobe 8.1.1. Target client: MiniMax Code 3.1.2 or later.

• npm test --prefix plugins/klarkxy/fablecut: 69/69 tests passed, independently rerun after review fixes. Regressions cover chained/chainless preview gain restoration after seeking/loading, DNS-pinned connections and redirects, managed media-path containment, and bounded MCP session retention.
• node scripts/validate.mjs plugins/klarkxy/fablecut: no errors or warnings.
• Staged whitespace check reports preserved whitespace in verbatim upstream font license texts and one final blank line in vendored analyze.js; other staged files pass.
• npm run check: package/repository validation passes; root tests pass 67/69. The two failures are existing symlink-fixture EPERM errors in test/files.test.mjs on this Windows environment, before the validator assertions run. The test and validator sources are unchanged; upstream base commit 62773d1 has a successful Ubuntu check.
• Existing warnings outside this package: missing README headings in mcode-token-usage-board and mcode-usage-monitor; stdout warnings in workflow-console, minimax-photo and minimax-video; missing README minimum-client-version declarations in xinyu-daily and anatomy-gallery. This PR does not change those packages.
• Prior local Host publish/open and UI smoke test: synthetic video import, linked video/audio placement, title creation, playback controls, reload persistence and a 4-second 1280x720/30 fps export; the editor reported export checks passed, with no final console errors or failed requests.
• Fresh-conversation Host MCP calls on 2026-10-25: fablecut_status, fablecut_get_project and fablecut_docs succeeded. Integration tests cover discovery of all 20 tools and representative editing/import writes.

Actual browser listening after the preview correction and real remote TLS downloads were not exercised; those regressions use VM and deterministic transport fixtures. Live Host write calls, macOS, optional Google Fonts/MediaPipe features, paid generation and sustained long/high-resolution exports remain unverified. Test projects, generated media, archives and local review artifacts are excluded from the commit.
