ESL Plugins

A curated collection of Claude Code workflow plugins by Encentral Solutions. Some we author; some are well-regarded community plugins we vet and pin to a known-good release. Either way you add one marketplace and install what you want.

This repository is a Claude Code marketplace — you add the marketplace once, then install any plugin from it.

Plugins

Plugin	Adds	What it does
compound-engineering	/ce-* skills	The full Every "compound engineering" toolkit — brainstorm, plan, debug, review, and compound learnings with AI agents (ce-brainstorm, ce-plan, ce-code-review, ce-compound, ce-debug, and more). Vetted and pinned to a specific release.
office-hours	/office-hours	A YC-style forcing-question brainstorm for a product idea or design decision — demand reality, the real status-quo competitor, the narrowest paying wedge, future-fit — then saves a one-page design doc.
design-review	/design-review	Designer's-eye QA of a live UI — consistency, spacing, hierarchy, AI-slop patterns, interaction feel — fixing issues atomically in source with before/after evidence.
security-review	/security-review	An adversarial security pass over a change — OWASP Top 10, STRIDE threat modeling, secrets hygiene, and supply-chain risk — with a concrete exploit path per finding.

The three ESL-authored plugins each ship a command plus a matching skill (skills/<name>/SKILL.md) that Claude can invoke on its own. compound-engineering is referenced from its upstream repository, pinned to a reviewed commit, so installing it brings the complete upstream plugin with every skill and agent.

Install

Add the marketplace, then install the plugins you want:

# Add this marketplace (once)
claude plugin marketplace add encentrals/esl-plugins

# Install a plugin
claude plugin install compound-engineering@esl-plugins
claude plugin install office-hours@esl-plugins
claude plugin install design-review@esl-plugins
claude plugin install security-review@esl-plugins

Then, in a Claude Code session, run /office-hours, /design-review, or /security-review — or just describe the task and let the matching skill kick in.

Keep them current with:
