known-errors skillA
known-errors is agent-read markdown (skill) from 0xsline/openchatcut: Use when a OpenChatCut tool call fails or returns an unexpected shape..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.
What the file says
# Known Errors
`edit_item` update raw shape:
- Wrong: `{ "id": "abc", "fromFrame": 30 }`
- Right: `{ "json": "{\"updates\":[{\"id\":\"abc\",\"fromFrame\":30}]}" }`
- Use this same `updates` shape for common moves, trims, and track changes.
`edit_item` add raw shape:
- The new item goes inside the `adds` array of the `json` transaction: `{ "json": "{\"adds\":[{...}]}" }`.
- Use `edit_item` for simple video placement, for example `{ "json": "{\"adds\":[{\"type\":\"video\",\"assetId\":\"...\",\"fromFrame\":0}]}" }`.
Timeline overlap:
- Error text: `Overlap: updated item at ... would overlap existing item at ... on this track.`
- Do not force the write or delete the conflicting item silently.
- Retry the `edit_item` transaction with an explicit available `trackId`, for example an update containing `"trackId":"V2"`, or ask the user which layer should win.
Workspace path restrictions:
- `push_asset` on the external MCP only accepts public http(s) URLs as `filePath`. It rejects local paths, workspace paths, and chat attachment paths.

How to install
mdr add 0xsline/openchatcut/known-errors@git:20260720.79e164dmdr add 0xsline/openchatcut/known-errors@sha256:4de4dd5c93454264Pin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
