Description

Problem

scp outputs per-file progress bars and percentage updates that waste tokens. The only useful information is the final transfer result (success/failure, bytes transferred).

Evidence

rtk discover (last 30 days): 21 scp commands, currently unhandled.

Typical usage pattern:

scp -i ~/.ssh/id_ed25519 /local/file deploy@host:/remote/path

Suggested approach

  • Strip progress bar lines (percentage, ETA, transfer rate)
  • Keep: filename, final status (success/error), total bytes
  • Related to ssh support (#783, #333) but scp is a distinct binary

Environment

  • rtk 0.30.0, macOS Darwin 24.6.0
  • Claude Code PreToolUse hook

Research direction
Examine the existing ssh filter implementation (likely in src/filters/ssh.rs) to understand the pattern for handling command output. Then, create a new filter for scp that strips progress bars but retains final status and bytes transferred. Test with common scp commands to ensure robustness.
