The Shift: Engineers Orchestrate Agents
Coding is no longer the bottleneck. Planning, review, and learning loops matter more than syntax. Each feature makes the next one easier to build.
Plan → Work → Assess → Reflect
| Step | What Happens | Key Tools |
|---|
| Plan | Agents research codebase + best practices, produce detailed implementation plans | /majestic:plan, architect agent |
| Work | Agents write code, tests, and iterate using real app feedback | /majestic:build-task, coder skills |
| Assess | Multi-angle review: security, performance, simplicity, conventions | /majestic:code-review, quality-gate |
| Reflect | Analyze session patterns, capture lessons so future agents improve | /majestic-tools:insight:reflect, /majestic:add-lesson |
See the Workflow Guide for detailed documentation.
Quick Start
Run the installer:
curl -fsSL https://raw.githubusercontent.com/majesticlabs-dev/majestic-marketplace/master/install.sh | bash
This gives you options to:
- Add marketplace (enables plugin installation)
- Add output styles (formatting guides)
- Add MCP servers (Sequential Thinking)
- Configure shell settings (env vars + alias)
- Install Beads (AI agent memory)
- Install all
Manual Installation
Claude Code
Run claude and add the marketplace:
/plugin marketplace add https://github.com/majesticlabs-dev/majestic-marketplace.git
Then install a plugin:
/plugin install {plugin-name}
OpenCode and Codex
Export Majestic plugins to OpenCode or Codex with schema-aware conversion:
./scripts/install-codex.sh
# Install all plugins
./scripts/install-codex.sh --all
# Install all plugins to OpenCode
./scripts/install-opencode.sh --all
# Install specific plugins
./scripts/install-codex.sh engineer rails tools
# Example (explicit): convert engineer, rails, and tools to OpenCode
# Output target: ~/.config/opencode
./scripts/install-opencode.sh engineer rails tools
# Install one plugin (short or prefixed)
./scripts/install-codex.sh engineer
./scripts/install-codex.sh majestic-tools
Both commands are now local to this repository and only require Ruby (scripts/convert-plugin.rb).
This runs a converter pipeline (not a plain file copy), so incompatible Claude metadata is translated for target formats.
disable-model-invocation frontmatter is preserved as part of source metadata parsing, but it does not exclude a command from conversion for OpenCode/Codex output.
Output locations:
- Codex:
~/.codex/skills/ and ~/.codex/prompts/
- OpenCode:
~/.config/opencode (opencode.json, agents/, skills/, plugins/)
Limitations: Codex still does not support some Claude Code features (Task, hooks, some MCP integrations), so behavior is reduced there.
