Ridgeline

Ridgeline is a command-line build harness for decomposing large software ideas into phased builds executed by AI agents. Current version 0.8.2, updated frequently. It orchestrates a multi-agent pipeline (shaper, designer, specifier, researcher, refiner, planner, builder, reviewer) driven by the Claude CLI. Key differentiators: ensemble-based spec/plan generation with multiple specialist agents, built-in sandboxing via Greywall or bubblewrap, resumable execution with git checkpoints and phase-level retry. Requires Node >=20, Playwright >=1.57, and the Claude CLI. macOS and Linux only; no Windows support.
