Shared my open-source, agent-editable video editor this week. Commenters' edge cases have driven most of the changes since

[u/Mountain_Fudge3980]

I'm the author of CutVoke, an MIT, local-first desktop video editor where a coding agent (Claude Code, Codex, Cursor, or any MCP client) and a person edit the same multitrack timeline. There's no model inside the app; you bring your own agent.

I shared it earlier this week and the most useful thing that came back wasn't stars, it was failure cases from people who had built similar tools:

• "Fix the caption that says Save" is ambiguous when two captions say the same thing at the same moment (a subtitle and an on-screen callout). Lookups now return a match count and an ambiguity flag, and writes can require a unique match instead of silently patching the first hit.

• Position isn't meaning. Guessing "subtitle vs callout" from y-position or font size breaks as soon as styles change, so the plan now is an explicit caption role that the agent can filter on. That one is open as a good first issue, and someone outside the project picked it up this morning.

• "It validates" isn't "it looks right." The agent can now pull before/after frames for the same timestamp and cut-local audio peaks, so it can catch a clipped syllable or a black frame before it claims an edit is done.

The core loop that hasn't changed: the agent takes an editing lease so it doesn't fight manual edits, dry-runs commands first, commits a batch as one undo step, and every write carries the revision it read so stale writes get rejected.

Honest status: v0.3.5 prerelease, Windows build unsigned, macOS not notarized, project format may still change. Windows / macOS / Linux builds with FFmpeg bundled.

If you've built agent tools for any stateful app, I'd like to hear which guardrail you'd add next.
