AI-powered development tools. 29 agents, 24 commands, 18 skills, 1 MCP server for code review, research, design, and workflow automation.
Create a new custom slash command following conventions and best practices
Full autonomous engineering workflow using swarm mode for parallel execution
Run comprehensive agent-native architecture review with scored principles
Create engaging changelogs for recent merges to main branch
Create or edit Claude Code skills with expert guidance on structure and best practices
Brutally honest Rails code review from DHH's perspective. Use when reviewing Rails code for anti-patterns, JS framework contamination, or violations of Rails conventions.
Visually compares live UI implementation against Figma designs and provides detailed feedback on discrepancies. Use after writing or modifying HTML/CSS/React components to verify design fidelity.
Iteratively refines UI design through N screenshot-analyze-improve cycles. Use PROACTIVELY when design changes aren't coming together after 1-2 attempts, or when user requests iterative refinement.
Detects and fixes visual differences between a web implementation and its Figma design. Use iteratively when syncing implementation to match Figma specs.
Creates or updates README files following Ankane-style template for Ruby gems. Use when writing gem documentation with imperative voice, concise prose, and standard section ordering.
Browser automation using Vercel's agent-browser CLI. Use when you need to interact with web pages, fill forms, take screenshots, or scrape data. Alternative to Playwright MCP - uses Bash commands with ref-based element selection. Triggers on "browse website", "fill form", "click button", "take screenshot", "scrape page", "web automation".
Build applications where agents are first-class citizens. Use this skill when designing autonomous agents, creating MCP tools, implementing self-modifying systems, or building apps where features are outcomes achieved by agents operating in a loop.
This skill should be used when writing Ruby gems following Andrew Kane's proven patterns and philosophy. It applies when creating new Ruby gems, refactoring existing gems, designing gem APIs, or when clean, minimal, production-ready Ruby library code is needed. Triggers on requests like "create a gem", "write a Ruby library", "design a gem API", or mentions of Andrew Kane's style.
This skill should be used before implementing features, building components, or making changes. It guides exploring user intent, approaches, and design decisions before planning. Triggers on "let's brainstorm", "help me think through", "what should we build", "explore approaches", ambiguous feature requests, or when the user's request has multiple valid interpretations that need clarification.

A Claude Code plugin marketplace featuring the Compound Engineering Plugin — tools that make each unit of engineering work easier than the last.
/plugin marketplace add https://github.com/EveryInc/compound-engineering-plugin
/plugin install compound-engineering
This repo includes a Bun/TypeScript CLI that converts Claude Code plugins to OpenCode and Codex.
# convert the compound-engineering plugin into OpenCode format
bunx @every-env/compound-plugin install compound-engineering --to opencode
# convert to Codex format
bunx @every-env/compound-plugin install compound-engineering --to codex
Local dev:
bun run src/index.ts install ./plugins/compound-engineering --to opencode
OpenCode output is written to ~/.config/opencode by default, with opencode.json at the root and agents/, skills/, and plugins/ alongside it.
Both provider targets are experimental and may change as the formats evolve.
Codex output is written to ~/.codex/prompts and ~/.codex/skills, with each Claude command converted into both a prompt and a skill (the prompt instructs Codex to load the corresponding skill). Generated Codex skill descriptions are truncated to 1024 characters (Codex limit).
Sync your personal Claude Code config (~/.claude/) to OpenCode or Codex:
# Sync skills and MCP servers to OpenCode
bunx @every-env/compound-plugin sync --target opencode
# Sync to Codex
bunx @every-env/compound-plugin sync --target codex
This syncs:
~/.claude/skills/ (as symlinks)~/.claude/settings.jsonSkills are symlinked (not copied) so changes in Claude Code are reflected immediately.
Plan → Work → Review → Compound → Repeat
| Command | Purpose |
|---|---|
/workflows:plan | Turn feature ideas into detailed implementation plans |
/workflows:work | Execute plans with worktrees and task tracking |
/workflows:review | Multi-agent code review before merging |
/workflows:compound | Document learnings to make future work easier |
Each cycle compounds: plans inform future plans, reviews catch more issues, patterns get documented.
Each unit of engineering work should make subsequent units easier—not harder.
Traditional development accumulates technical debt. Every feature adds complexity. The codebase becomes harder to work with over time.
Compound engineering inverts this. 80% is in planning and review, 20% is in execution:
