Rageatc OSS — Development skill for Claude Code

rageatc-oss

**Rage Against The C** - pick your own C to rage against.

Two plugins for Claude Code / Cowork, built on the idea that we're using AI wrong: the speed of its output tricks us into rushing the input. These plugins slow you down on the inputs - proper briefing, good questions asked back, review before anything reaches you - so the outputs are worth keeping.

What's inside

Skills and agents to help you with your work or life. Each plugin works alone, but they fit together. Software work uses both; for non-coding work you only need core.

Plugin	Purpose
rageatc-core-oss	To tackle even the most challenging thinking work. Ideate, structure the problem, then solve it with an agentic loop that reviews its own outputs and learns from them.
rageatc-code-oss	For building software the slow way. Tests come first, architecture is designed before coding starts, work is broken into small chunks, code is reviewed. Adapts to project size, from a one-line fix to a multi-week build. When your software has a UI, builds a design system from scratch or extracts one from existing code, then keeps the build aligned to it. Also carries tools that extend what your AI agent can reach: browse websites, read and write PDFs, hand tasks to a local model or Codex.
