Feature Request rtk ssh subcommand — remote command output filtering #333
Description
rtk ssh subcommand — remote command output filtering
Running rtk discover on a codebase with multiple remote dev servers shows SSH as by far the largest unhandled savings opportunity:
TOP UNHANDLED COMMANDS
| Command | Count | Example |
|---|---|---|
ssh [host] |
787 | ssh host "cd /project && git log --oneline -20" |
ssh [host2] |
200 | ssh host2 "cat /etc/some-config" |
ssh [host3] |
30 | ssh host3 "diff /path/file1 /path/file2" |
~1,000 SSH invocations in 30 days, all piping back verbose output that rtk could filter if it had a way to intercept.
Proposed: rtk ssh
rtk ssh user@host "pytest tests/" # pipe remote stdout through rtk pytest
rtk ssh user@host "git log -n 20" # pipe through rtk git log
rtk ssh user@host "cat big-file.log" # pipe through rtk logThe subcommand would:
- Execute the remote command via SSH normally
- Detect the remote command type (first token after the quoted string)
- Pipe stdout through the appropriate existing
rtkfilter
Why the hook can't handle this today
The PreToolUse hook could rewrite ssh host "cmd" → ssh host "cmd" 2>&1 | rtk log, but this breaks exit codes and interactive sessions, so a dedicated subcommand is safer.
Fallback behaviour
If the remote command type isn't recognised, pipe through rtk log (dedup + truncate) as a generic fallback — still better than raw output.
Environment: macOS, Claude Code PreToolUse hook, rtk 0.24.0
