What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

name: openchatcut
description: Connect an MCP-capable coding agent to OpenChatCut and edit local video projects. Use when the user asks to install, connect, or set up OpenChatCut; inspect or edit an OpenChatCut project; work with its timeline, transcript, captions, media, generation, motion graphics, audio, color, or export tools; or recover from an OpenChatCut MCP error.

# OpenChatCut

OpenChatCut is a local-first, agent-native video editor. This skill is the
single external entry point; specialized editing guidance remains inside the
running editor and is loaded on demand with `load_skill`.

## Route the task

- Install, connect, or diagnose the MCP server: read
  `references/getting-started.md`.
- Inspect or modify a project: read `references/editing-workflow.md`.
- Recover from a failed tool call, stale session, or missing editor:
  read `references/known-errors.md`.

## Essentials

1. Start OpenChatCut before connecting. The default MCP endpoint is
   `http://localhost:5199/api/external-mcp/mcp`.
2. Call `openchatcut_status`, then `list_projects`. Select a project only when
   the user names it or the current context identifies it.
3. Call `load_skill` before specialized work. It is read-only and requires
   neither `begin_edit_session` nor `editSessionId`; available names and support
   files come from the live MCP tool description.
   With progressive exposure enabled, this call reveals the skill's referenced
   tools and emits `tools/list_changed`; refresh the list before continuing.
4. Before project reads or edits, call `begin_edit_session`. Keep its
   `editSessionId` and pass it to every draft-safe editor tool.
5. Set `reuseExisting: true` on `begin_edit_session` to reuse your active draft
   or adopt an unchanged orphan. Existing operations and approval mode are kept.
   If reuse is rejected, call `list_edit_sessions`. Use `recover_edit_session`
   only with a listed `recoveryActions` value; another online owner must finish
   or discard its own session.
6. Use `approvalMode: "manual"` unless the user explicitly asks for unattended
   application. In manual mode, the user approves the complete proposal in
   OpenChatCut. In auto mode, `review_edit_session` applies the complete draft.
7. Finish with `review_edit_session`. Report success only after
   `get_edit_session` returns `applied`.

Questions

What does the OpenChatCut skill do?

Open-source, local-first conversational AI video editor with a professional multi-track timeline, Agent Skills, MCP integration, and Remotion rendering.

Is OpenChatCut safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can OpenChatCut access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

Which assistants does OpenChatCut work with?

Its documentation mentions claude-code and codex. That is what the text claims, not a compatibility test we ran.

How current is this page?

The grade is for one exact copy of the source (f9f0498ec41d), read on 2026-10-20. The repository is watched, and a new audit runs when it changes — this is the first audit.
