Module rtk 

RTK (Rust Token Killer) integration module

This module provides token-saving functionality by filtering and compressing bash command outputs before they reach the LLM context. It wraps the rtk CLI binary to achieve 60-90% token savings on common development commands.

Features

• Command rewriting via rtk rewrite
• Stats extraction (git diff, cargo build, etc.)
• Error-only mode for test runs
• Output grouping and deduplication
• Structure-only mode for JSON/data files

Usage

Enable with the rtk feature flag:

cargo run --features rtk

Structs

RtkMetrics

Aggregate RTK metrics across all command executions

RtkResult

Result of RTK command rewriting

RtkTracker

Thread-safe metrics tracker

TokenSavings

Token savings for a single command execution

Constants

RTK_NOT_INSTALLED_HELP

User-facing guidance shown by /rtk only when the auto-download itself failed (no network, GitHub unreachable, unsupported platform). The happy path installs RTK silently on first use, so this is the rare failure note.

Functions

global_tracker

Get the global RTK tracker instance

is_rtk_available

Check if the rtk binary is available (bundled, in PATH, or auto-downloaded). Async + cached.

rewrite_command

Rewrite a bash command to use RTK as a proxy.

warm_up

Resolve RTK in the background at startup (triggering the first-use auto-download if needed) so the first bash command never blocks on it.
