The filter that keeps shell noise out of your agent’s context
A fast Rust proxy that compresses shell, test, Git, container and build output before an AI coding agent reads it — 100+ commands, integrations for 18 agents, and a maker post that keeps the claim honest.

Patrick Szymkowiak @pszymkowiak
First-person build note and launch response
Apache-2.0; free prebuilt binaries and package-manager paths
What it does
Stop irrelevant terminal output from eating your agent’s context — without pretending output reduction is a bill reduction.
Who it helps
Developers running coding agents on real projects with noisy test and build output.
How it was made

- Rust · Proxy implementationClaude Code · Build agent — maker-reported
- Szymkowiak built RTK with Claude Code and published a first-person post recording the method, early downloads and the launch response.
- The tool targets a real agent-workflow cost across 100+ commands and 18 coding agents, with prebuilt binaries for Windows, macOS and Linux.
- The documentation now states the claim precisely: up to 90% less Bash output is not the same as a 90% smaller bill.
What the person did
The product decision, scope and public documentation are the maker’s; the repository credits the RTK core team.
What we know
Creator-reported: The repository (81,719 stars, 5,173 forks, updated 2026-09-25) and the maker’s first-person post; the maker’s GitHub profile resolves to the same person.
Access checked — 2026-09-27 · Opened the repository and the maker post on 2026-09-27; star and fork counts are from that check.
Can you use it?
The source is Apache-2.0; logos and screenshots carry no separate grant, so we link and host no media. The cover is an original Made With Models illustration, not a screenshot of the tool.
