Description

Problem

python3 and virtual-env Python commands produce verbose output that wastes tokens:

  • python3 -m pytest — full test output with per-test lines, warnings, tracebacks
  • .venv/bin/python -m pytest — same, but absolute path bypasses rewrite
  • /opt/homebrew/bin/python3 -c "..." — inline scripts with large stdout
  • python3 << 'PYEOF' — heredoc scripts (related: #1243)

Evidence

rtk discover (last 30 days):

  • python3 <<: 47 commands
  • .venv/bin/python: 16 commands
  • /opt/homebrew/bin/python3: 15 commands
  • Total: 78 commands, currently unhandled

Suggested approach

  1. Rewrite coverage: match python3, .venv/bin/python, absolute-path python binaries
  2. pytest filter: compress per-test PASSED/FAILED lines, keep summary + first failure traceback
  3. General python filter: truncate large stdout, keep first/last N lines

Environment

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

Contributor guide

Research direction
Study the existing output filter implementations in the codebase, particularly for other commands like make or npm, and replicate the pattern for python3 paths and pytest output.
