Rule file not found

Error message

Rule file not found

What it means

handleSelectFile in SkillRuleGenerator reads a user-picked file via ipcBridge.fs.readFile and throws 'Rule file not found' when the returned content is null/undefined. This indicates the file exists in the tree listing but its content could not be read (deleted between listing and read, permission denied, or binary/oversized content mapped to null).

Solutions

1. Confirm the rule file still exists and is a readable text file within the workspace
2. Reopen the picker to refresh the listing, then reselect
3. Check read permissions on the file and parent directories
4. For very large rule files, split them or reduce size

const exists = await ipcBridge.fs.exists?.invoke({ path: file.fullPath });
if (!exists) { message.error('File no longer exists'); return; }

try { const c = await ipcBridge.fs.readFile.invoke(...); if (c == null) return; } catch { /* show retry */ }

When it happens

Trigger: Selecting a file in LoadRuleModal whose read returns null: file deleted after the directory listing, unreadable permissions, or a path outside the active workspace.

Common situations: Rules/skills files edited externally or removed by a sync tool while the picker was open, workspace switched, or selecting very large or binary files the reader refuses.
