fix: restrict .env file permissions to 0600 (#25562)#25779
Merged
Conversation
Set file mode 0600 on ~/.hermes/.env after creation in the installer and after every write via memory_setup._write_env_vars(). This ensures only the file owner can read/write API keys and tokens, matching standard practice for credential files (.netrc, .aws/credentials, .ssh/config). Fixes #25477

API keys in
~/.hermes/.envwere created with default permissions (often 0644 = world-readable). Locks them down to 0600 in two places:scripts/install.sh— initial installhermes_cli/memory_setup._write_env_vars— re-saves throughhermes setup memoryCloses #25477. Same intent as @alaamohanad169-ship-it's #25560 (closed); we picked this one for the broader Python-side coverage.
