harness-standard

A standardized multi-agent harness for Claude Code and OpenCode: Spec-Driven Development roles (Leader, Spec Author, Implementer, Reviewer) installed into any project with a single command.

Problem

Coding agents work well in the small and drift in the large. Teams need one repeatable process — specs, roles, gates — independent of stack.

Highlights

• 7 stacks covered (Java/Spring, Python, Node/TS, Rust, and more) with per-stack conventions.
• Single-command install; conventions template includes SonarQube/code-quality rules.
• Born from daily use across personal projects — this portfolio is built with it.
