Launched September 6 as MIT-licensed Rust, Kit replaces a tool menu with a single tool where the model writes a Runlet program running shell commands, editing files, running tests, delegating to subagents and returning structured data inside one round trip (GitHub). On Speakeasy's own July-August production tasks it reports median 49.7k input tokens per hand-written line against Claude Code's 99.6k, and 60% fewer user messages per session. Vendor-reported and unreproduced, so weight it accordingly, but the architectural bet is legible: context savings come from collapsing tool round trips.

The headline number on this repo is 65% token savings. The number you should actually care about is 33.2%, and the reason to trust the project is that the maintainer tells you the difference. JuliusBrussee/caveman cut v2.1.0 on August 16 at 19:22 UTC (GitHub). The GitHub API r...
A spec is a press release until someone who didn't write it implements it. GitHub made Agent Plugins 1.0 generally available on August 12 across VS Code, Copilot CLI, the Copilot SDK, and the Copilot app on all plans. The spec, published August 6, was co-authored by AWS, Anysp...
RTK (Rust Token Killer) is a single Rust binary that sits between your terminal commands and your AI coding agent. When Claude Code or Cursor calls git status or ls -la, RTK intercepts the output and compresses it before it hits the context window. That's it. One trick. And it...
A single Rust binary is saving agentic coding users 60-90% on token costs, and it took about five minutes to set up. RTK (Rust Token Killer) released v0.37.1 on April 18 and sits at 30,500 GitHub stars. The tool acts as a CLI proxy between your AI coding assistant and shell co...
The most under-hyped tool of the week is a single Rust binary with zero dependencies that sits between your coding agent and your terminal, compressing command outputs before they hit the context window. rtk (Rust Token Killer) intercepts common dev commands — cargo test, git...
v0.1.117, tagged August 28 one day after v0.1.116 and pushed again today, is an MIT-licensed Rust tool that turns Claude Code, Codex or OpenCode into research agents that propose an idea, change code, launch an experiment and inspect evidence in a loop. Each run gets an isolat...
