Spectrum Plugins

Personal Claude Code plugin marketplace. It ships four plugins that can be installed independently:

Plugin	Purpose	Skills
spectrum	Spec-driven development harness — Spec → Plan → Execute → Sync cycles with quality gates and session-persistent state	/spectrum:spec, /spectrum:plan, /spectrum:exec-task, /spectrum:debug, …
coding	Everyday coding utilities	/coding:qcommit, /coding:pr, /coding:sync-base, /coding:cpp-dev, /coding:test-best-practices
learning	Learning and research tools	/learning:cognitive-learning, /learning:session-prerequisites, /learning:research
fluent-korean	Output style that makes Claude write clear, fluent Korean — mirror of snflkd/fluent-korean	output styles fluent-korean, fluent-korean-not-coding

spectrum declares coding as a dependency (its workflow ends with /coding:qcommit → /coding:pr).

Installation

Register the marketplace once, then install the plugins you want:

/plugin marketplace add https://github.com/CHOIMINSEOK/Spectrum
/plugin install spectrum@spectrum
/plugin install coding@spectrum
/plugin install learning@spectrum
/plugin install fluent-korean@spectrum

Skills, subagents, and hooks are bundled inside each plugin — nothing else to copy. Pick up new versions with:

/plugin update

The spectrum plugin relies on a few external MCP servers and skills for its QA stages; see External Dependencies in its README.
