I really think the future are agent harness kits like `itayinbarr/little-coder`. Small, minimal, customizeable pi-coding-agent series of extensions, that has some specialized deterministic logic to "heal" common small LLM errors like getting stuck into thinking loops and syntax errors on tool calling.

This one has "generic healing" for issues present in the current generation of local small LLMs, but if things we see from Frontier LLMs generalize, "optimized healing" for quirks present on your pick of local LLM would be more useful.
