Timeline Studio now exposes the open editor as structured browser tools for compatible WebMCP agents. Agents can review and apply supported edits to the same visible timeline, then save a new editable project copy.
Highlights
- Nine browser tools cover project, track, clip and transcript inspection; main-visual edit preview and apply; playhead seeking; guarded undo; and
.timelinedownloads. - Reorder existing main-visual clips and trim eligible plain 1× videos using absolute source times. Semantic review, stale-state checks, existing ripple behavior, track locks and normal undo history protect the editing workflow.
- Preserve timeline markers, captions and audio links. Seeking and progressive filmstrip refinement no longer invalidate an unchanged agent edit. Detached narration captions can be queried through their remembered source.
- Tool descriptions, review controls and errors are localized in all 13 interface languages.
- Publish the browser editing Skill, SHA-256-verified discovery index, agent guide, HTTP discovery links and llms references. Missing protocol documents return real 404 responses; the root URL still opens the editor directly.
- Include main's timeline scrubbing improvements and X community link since v1.0.7.
WebMCP remains experimental and requires a compatible native browser API and agent host. Unsupported browsers keep the normal editor. The initial browser tool set supports inspection, main-visual reordering and basic trimming; it does not expose AI generation, media import, arbitrary JavaScript, remote HTTP MCP, or rendered-video export. Saving creates an editable project archive.
中文说明
- 新增 9 个 WebMCP 浏览器工具，支持读取工程、轨道、片段与字幕，审阅并应用主画面重排和基础裁剪，以及定位、撤销和下载可编辑工程。
- Agent 与用户操作同一条可见时间线，沿用波纹编辑、轨道锁和撤销历史；工程变化时旧方案失效，时间线标记和字幕音频关联完整保留。
- 工具说明、审阅控件与错误提示覆盖全部 13 种界面语言，补齐浏览器 Skill、发现索引、指南和链接。
- WebMCP 仍是实验能力，需要兼容的浏览器与 Agent 宿主；首版保存的是
.timeline工程包，不负责渲染成片。
Validation
npm run check passed, with existing lint warnings retained. Real browser calls verified inspect → preview → apply → seek → undo → download on main. The 10-second test timeline returned from an 8-second edit to its original sequence; range markers beyond the media end stayed intact without extending rendered duration. GitHub CI passed. Netlify production verification confirmed the deployed editor bundles, correct discovery MIME types and Link headers, exact Skill bytes and SHA-256 digest, and real 404 responses for missing protocol resources.
Install the published local project Skill for Codex:
gh skill install MartinDelophy/ai-video-editor edit-timeline-studio --pin v1.0.8 --agent codex --scope userSkill installation copies the workflow. Local commands require a repository checkout with its Node dependencies; the browser tools operate on the project in the open website.
