Jan-Erik Lysander's Claude Code Plugins

My personal collection of Claude Code plugins for engineering, domain-driven design, and hook automation.

Installation

From a Claude Code session, add the marketplace first:

/plugin marketplace add janeriklysander/jel-claude-plugins

Then install any plugin below. If you prefer to browse interactively, run /plugin.

Plugins

engineering-toolkit

Multi-agent code review across 7 dimensions (correctness, security, architecture, performance, maintainability, observability, documentation) and doc authoring with the Diátaxis framework, 8 templates, and linting.

/plugin install engineering-toolkit@jel-claude-plugins

ddd-design

Structured Domain-Driven Design discovery — interview-driven, one question at a time, produces a domain model document.

/plugin install ddd-design@jel-claude-plugins

create-hook

Step-by-step guide for writing Claude Code hooks as shell scripts and wiring them into settings.json.

/plugin install create-hook@jel-claude-plugins

Reference guides

Standalone reference documentation for Claude Code users, hosted at janeriklysander.github.io/jel-claude-plugins:

• 1Password SSH agent setup — configure 1Password's SSH agent to work inside Claude Code's sandbox (macOS and WSL2)
• Claude Code security hardening — three-layer permission and sandbox configuration to reduce prompt fatigue and protect against prompt injection

Optional dependencies

The engineering-toolkit plugin's lint script uses Vale and markdownlint. Both are optional — if you don't have them installed, the skill and documentation agent skip linting and note it in their output. See the engineering-toolkit README for install instructions.

Development setup

After cloning, configure git to use the tracked hooks:

git config core.hooksPath .githooks

A pre-commit hook enforces that any change to a plugin includes a version bump in that plugin's plugin.json.

Contributing

Feedback and bug reports are welcome via GitHub Issues. This project has no roadmap — it's a personal collection shared with the community.
