forge Project

Fork of the Forge GNOME tiling extension worked through a 140-issue backlog with Claude — 200+ bugs fixed, a unit test suite, end-to-end tests running in CI, and a keybinding cheatsheet overlay — tagged as a beta and used daily, though not yet upstreamed.

rust-symex Project

Rust port of Angr’s core symbolic execution engine that matches or beats the Python original on 13 of 16 CTF benchmarks (up to 12.7x on the largest) and is now the default engine, built to over 160K LoC across 2,593 iterations of an autonomous agent loop.
