rtk — Trim Command Output

rtk is a small Rust binary that filters repetitive dev-tool output (timestamps, progress bars, duplicate warnings) before it reaches the model.

Install

Binary: https://github.com/rtk-ai/rtk/releases — place in ~/workspace/bin/ (Apache-2.0). No cargo needed.

~/workspace/bin/rtk --version

Usage

Prefix noisy read-only commands:

~/workspace/bin/rtk git diff
~/workspace/bin/rtk git status
~/workspace/bin/rtk tsc --noEmit
~/workspace/bin/rtk pytest -q

When NOT to use

• The output feeds another program or gate (build-check parsing, JSON extraction, test-count assertions) — those need the raw bytes.
• The output is already short.
• You need exact line numbers/byte offsets for a downstream edit — verify against the real file afterwards.

Notes

• rtk only filters presentation noise; it never changes exit codes.
• If a trimmed section looks suspicious, re-run without rtk on that part.
