Failed to read {}: {e}

Error message

Failed to read {}: {e}

What it means

The helper read_or_empty maps tokio::fs::read_to_string failures (other than not-found, which yields "") into this error — e.g. permission denied or an I/O error on MEMORY.md/SKILL.md. It means the existing file exists but could not be read, aborting the read-modify-write.

Solutions

1. Check file permissions on the target MEMORY.md/SKILL.md and repair them
2. Rule out disk/FS errors; then retry the update
