MaskShift released as model-agnostic coding harness with zero NPM dependencies

MaskShift, available on GitHub, is a local-first coding harness that runs models without external dependencies using Node 22 built-ins. The tool enables models without native tool-calling APIs to execute tools by rendering schemas into system prompts and parsing tool calls from text responses. It provides a unified control plane for repository understanding, file edits, shell access, Git recovery, and language servers.
