Agentic 1.4.0 makes installation explicit across twelve coding harnesses and documents the complete engineering workflow, from standards and requirements through design review, implementation, QA, and security.
Installation
- Native Claude plugin metadata, a portable plugin manifest for Codex and Antigravity, a Codex marketplace, and Pi package metadata.
- Named global/project skill targets for Claude, Codex, Pi, OpenCode, Antigravity CLI/App, Gemini CLI, Cursor, GitHub Copilot, Cline, Windsurf, and Amp.
- Dependency-aware selected installs, destination deduplication, local links, and update/removal coverage.
- Project setup now generates AGENTS.md by default and selects the current harness’s instructions.
Documentation and verification
- README covering the full scope of Agentic, with direct installation and first-use instructions.
- Linked installation, usage, language standards, and development/verification guides.
- Registry-generated, version-synchronized manifests and strict validation of the packaged distribution.
- A distributable that retains standalone resources and licenses while excluding development context and local build/cache files.
Updating
For Claude Code:
/plugin marketplace update agentic
/plugin update agentic@agentic
For direct skill installs, repeat the original scope and target with --update, for example:
npx -y github:igmrrf/agentic skills --global --agent codex --updateExplicit --agent all installs to every supported harness location. With no --agent, the default remains Claude plus shared .agents skills. Named global Gemini and Antigravity targets now use their native directories; remove obsolete shared copies only when other harnesses no longer need them.
