Itay Wolfish
I build full-stack systems and the infrastructure under them, then write down what actually worked.
Founding platform engineer at Echo, running the AWS/Kubernetes platform under an AI product built on a deliberately boring stack. Eight years across full-stack and devops, based in Tel Aviv. Currently learning Rust in public. The write-ups are in Writing.

Testless against hono: the receipts
I ran testless against honojs/hono’s real commit history. Two fixes selected 12 of 2,684 tests and 39 of 2,681. A third selected 47%, and I’m not hiding that one.

adeptability 1.4 to 1.9: publishing skill libraries, composing agents into scheduled loops, and admitting when a harness drops a file.

I got tired of CI re-running tests nobody doubted
testless: a Rust CLI that reads a git diff, walks a static call graph across TypeScript, Go, and Rust, and prints the exact tests a change impacts.

adeptability
A Go CLI that lets you author an AI coding skill once and render it into Claude Code, Cursor, Copilot, Codex, OpenCode, and 50+ other agents. Dotfiles for your AI coding agents.

hookguard
A trust-first git hook manager in Rust. Committed hooks install themselves the moment you clone a repo, but nothing executes until you accept the exact commands, and consent is keyed to their content so upstream can't swap them under you.

Scrolls Buddy
A scrolling planner for the MapleRoyals community: per-slot scroll recommendations, stat progression, profit/loss, and session history, backed by a real relational data layer and product analytics, with zero servers to run.

testless
A Rust CLI that selects tests at function granularity from static AST analysis. It reads a diff, walks a tree-sitter-built graph of defs, tests, calls, and reads, and outputs the exact tests a change affects, free and local, with no runtime coverage instrumentation.
