It Was the Harness, Not the Model — 90% of ItFive agents, one local model, one frozen PNG-decoder suite: most failures were finishing, false passes, and loop guards
Greg Herlein's controlled study runs five coding agents on the same local Qwen coder for a held-out PNG decoder suite. ~90% of failures were harness problems (turn caps, early 'done', false-pass self-tests); a bigger quantization fixed none of them.

Everything Is a Stream: runtime composability over compile-time plugins
Antigma Labs stabilizes Ante v0.2.0’s Unix-inspired wire protocol—operations in, events out over stdio, sockets, or WebSockets—so agent engines stay separate from UIs while SemVer locks the streaming contract.

Executable Scripts with Dependencies
The Unix shell is great for supporting executable scripts via the shebang header, but I’ve always found scripting languages limiting, due to the inability to specify dependencies (other than the standard library). This has always been Python’s appeal with its “batteries included”, but I dislike Python, and its standard library isn’t enough either. And then, Scala CLI has spoiled me, now being my favorite way to build scripts.
