Default-on protocol: Try
rtkfor any command with long output. Skip only when output is trivially short. Saves 60-90% of tokens wasted on progress bars, boilerplate, and long listings. Recovers full error output via tee files when commands fail.
Token Saver is an AI agent skill that wraps RTK (Rust Token Killer, 67k⭐) — a CLI proxy that intercepts bash commands and strips redundant output before it reaches the LLM context.
rtk --version # check installed
skill("rtk") # load this skill
rtk git status # use it- Long/noisy output →
rtkprefix. Always. - Short output → run directly.
- Failure → read the tee file for full error output.
See SKILL.md for the full protocol (tee recovery, before/after examples, troubleshooting).
