Nanocode: Building an Agentic Coding Partner with Constitutional AI and Tool-Calling
Summary
The article provides an in-depth look at nanocode, a project to build an agentic coding partner guided by a simple SOUL persona. It details a templated tool-calling interface (Read, Edit, Grep, Bash), a Constitutional AI training pipeline (SFT and DPO-based preference learning), and extensive dataset generation and evaluation for agentic coding tasks. The work covers practical implementation, tooling, and considerations for aligning agentic code assistants with a friendly personality.
