macOS Invocation

Resolve <SSH_SKILL_ROOT> from the loaded skill, then use the local POSIX path.

python3 "<SSH_SKILL_ROOT>/scripts/ssh_skill.py" doctor --json
python3 "<SSH_SKILL_ROOT>/scripts/ssh_skill.py" exec example-host "hostname"
python3 "<SSH_SKILL_ROOT>/scripts/ssh_skill.py" download example-host "/var/log/app.log" "./app.log"

• The runtime prefers /usr/bin/ssh and falls back to PATH discovery.
• Keep local and remote path arguments separate.
• Keep the remote command as one process argument.
• Do not use a nested shell command string.
• SSH_AUTH_SOCK and /usr/bin/ssh-add provide local agent diagnostics.
• Parse the single stdout result separately from optional real-time JSONL progress on stderr.

Use Python 3.10-3.13. The skill does not require Homebrew when a compatible Python and the system OpenSSH client are already available.
