## Writing

- [k-onfusion: 200,000 tools, and the agent picks the wrong one](https://jaeaeich.com/writing/k-onfusion.md): I gave an AI agent 200,000 tools and it went from solving 85% of tasks to 30%, mostly by calling a lookalike of the right tool.
- [s3z: a hand-rolled S3 client in Rust that outruns aws-cli](https://jaeaeich.com/writing/s3z.md): I built s3z, an S3 client in Rust, and got it level with mc on downloads and ahead of mc, s5cmd and aws-cli on uploads, mostly by undoing my own clever ideas.
- [Poiesis v0.2: from seven Pods per task to one](https://jaeaeich.com/writing/poiesis-rewrite.md): Poiesis v0.1 ran a three-executor task as seven Pods held together by Redis, and v0.2 runs it as one, using a Kubernetes feature I’d talked myself out of.
- [Poiesis v0.1: building a TES server to understand one](https://jaeaeich.com/writing/poiesis.md): Poiesis v0.1 is a GA4GH TES server for Kubernetes I wrote in Python after a summer on TESK: how it runs a task, and what I already know is wrong with it.
- [vpn: a VPN I only pay for while I’m using it](https://jaeaeich.com/writing/vpn.md): A service I use is geo-restricted, so I wrote one command that runs my own VPN on EC2 and stops the instance, and the bill, as soon as I’m done.

## Projects

- [poiesis](https://github.com/jaeaeich/poiesis): Runs GA4GH TES tasks on Kubernetes, one Pod per task, with a Helm chart that an outside organisation has forked and now runs in production.
- [metis](https://github.com/jaeaeich/metis): A workflow engine in Rust where Nextflow, Snakemake and CWL plug in behind one trait and the API talks to its workers over NATS JetStream, and on one node it held about 2,000 submissions a second with more than 10,000 workflows in flight.
- [s3z](https://github.com/jaeaeich/s3z): An S3 client written from scratch in Rust, with Python and Node bindings, that downloads up to 3× faster than aws-cli while using 17 MB of memory where aws-cli needs 412, with the benchmarks committed in the repo.
- [poiesis-mcp](https://github.com/jaeaeich/poiesis-mcp): An MCP server, so AI assistants like Claude and Gemini can submit and babysit compute jobs on any GA4GH TES server.
- [k-onfused](https://github.com/jaeaeich/k-onfused): A harness that gives a Claude agent up to 200,000 tools to pick from and watches where finding the right one breaks, with every trial graded and traced so you can see exactly which lookalike it picked instead.
- [poiesisd](https://github.com/jaeaeich/poiesisd): poiesis without the Kubernetes, so a single docker compose command gets you a task service with a web UI.
- [jupyter_s3fs](https://github.com/jaeaeich/jupyter_s3fs): Mounts S3 into Jupyter over FUSE, so remote workflow outputs look like local files.
- [vpn](https://github.com/jaeaeich/vpn): One command starts an EC2 VPN and connects to it, and the same command shuts it down again, so it only costs money while I’m actually using it.
- [components](https://components.jaeaeich.com): The design system this site is built from: charts, diagrams, callouts and code blocks as Astro components, with a live showcase and visual regression tests in CI.
