Compound Marketplace

A Claude Code plugin marketplace featuring the Compound Engineering Plugin — tools that make each unit of engineering work easier than the last.

Claude Code Install

/plugin marketplace add https://github.com/kieranklaassen/compound-engineering-plugin
/plugin install compound-engineering

OpenCode + Codex (experimental) Install

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 ~/.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).

Workflow

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.

Philosophy

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:
