Description

Users receive false positive notifications like:

⚠️ 📝 Edit: in ~/.openclaw/workspace/MEMORY.md (702 chars) failed

even when the file was successfully written. This is caused by the warning policy in resolveToolErrorWarningPolicy (src, line ~177016) unconditionally returning showWarning: true for all mutating tool errors, without checking if the error is recoverable.

Root Cause

In pi-embedded-CbCYZxIb.js, the warning policy has two branches:

Non-mutating tools (exec, bash, etc.):

return {
  showWarning: !params.hasUserFacingReply && !isRecoverableToolError(params.lastToolError.error),
  includeDetails
};

Mutating tools (edit, write, etc.):

return {
  showWarning: true,  // ← always shows, ignores recoverable errors
  includeDetails
};

The non-mutating branch correctly suppresses warnings for recoverable errors. The mutating branch does not.

There is already a recovery wrapper (wrapHostEditToolWithPostWriteRecovery) that catches cases where the edit tool throws but the file was correctly updated. However, this wrapper only handles errors thrown by the underlying tool — it does not prevent lastToolError from being set when other error paths trigger before recovery completes.

Reproduction

1. Have frequent edits to workspace files (MEMORY.md, daily memory files, fear_state updates)
2. File lock contention or transient I/O timing causes the edit tool to report an error
3. The recovery wrapper may or may not catch it depending on timing
4. User receives a false positive notification

Proposed Fix

Add recoverable error check to the mutating tool branch, matching the non-mutating behavior:

if (params.lastToolError.mutatingAction ?? isLikelyMutatingToolName(params.lastToolError.toolName)) {
  return {
    showWarning: !isRecoverableToolError(params.lastToolError.error),  // ← add this check
    includeDetails
  };
}

This is a one-line change that aligns mutating tool warning behavior with non-mutating tools, while still showing genuine failures.
