howells-arc is a Claude Code plugin that guides a full product-development arc from exploration and validation through planning, TDD-oriented build, and review to a working implementation.
About
howells-arc is a Claude Code plugin from howells/arc described as taking you from idea to working implementation in one flow—explore, validate, plan, and build. For developers, that reads as a lightweight alternative to juggling separate brainstorming, planning, and execution skills without a handoff gap. Catalog keywords highlight arc, complete lifecycle, design, planning, review, TDD, vision, and workflow, which signals a methodology plugin rather than a single API connector. Canonical placement on the idea/discover shelf reflects where you first open ARC; in practice it spans validate and build heavily once you commit. With one bundled plugin and about 16 GitHub stars, it is a community workflow pack best for developers who want structured phases inside Claude Code instead of freeform chat. Confidence is moderate because detailed SKILL.md gates were not in the ingest snippet—treat journey-wide scope as aligned with the stated full-lifecycle promise.
- End-to-end lifecycle workflow: explore, validate, plan, and build in one plugin
- TDD and implementation emphasis from vision to working code
- Planning and design steps before heavy coding
- Review and shipped-quality framing in the development workflow
- Single-plugin bundle (pluginCount: 1) from howells/arc

Who is it for?
