Plugin
Slash commands, tracks, and built-in agents for Claude Code, Cursor, Codex CLI, and Copilot CLI.
Build with Specs. Code with Context.
Archcore is a git-native context layer for AI coding agents. Use it to manage specs, architecture, decisions, rules, plans, and project knowledge, and make the right context available throughout spec-driven development and implementation. Agents read it through MCP rather than re-reading flat Markdown files every turn.
