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	Skill("blueprint"), architect agent
Work	Agents write code, tests, and iterate using real app feedback	Skill("build-task"), coder skills
Assess	Multi-angle review: security, performance, simplicity, conventions	Skill("code-review"), quality-gate
Reflect	Analyze session patterns, capture lessons so future agents improve	/reflect

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:

1. Add marketplace (enables plugin installation)
2. Add output styles (formatting guides)
3. Add MCP servers (Sequential Thinking)
4. Configure shell settings (env vars + alias)
5. Install Beads (AI agent memory)
6. 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.

Project Setup

Initialize Project Configuration

After installing plugins, run this command in your project to set up AI agent configuration:

Skill("init")

This creates:

• AGENTS.md - Human-readable guidance for Claude (WHAT/WHY/HOW framework)
• .agents.yml - Machine-readable config for commands
• CLAUDE.md - Symlink to AGENTS.md

.agents.yml Config

The .agents.yml file stores project-specific settings that commands read automatically:

# .agents.yml - Project configuration for Claude Code commands
default_branch: main
tech_stack: rails              # rails | python | generic
app_status: development        # development | production
task_management: github        # github | linear | beads | file | none
workflow: worktrees            # worktrees | branches
branch_naming: type/issue-desc # feature/desc | issue-desc | type/issue-desc | user/desc
lessons_path: .agents/lessons/

Commands like Skill("code-review"), /git:create-pr, and Skill("build-task") read this config automatically.

Custom Config Path: Override the config filename with AGENTS_CONFIG environment variable:

export AGENTS_CONFIG=".my-project-config.yml"

CLAUDE.md Instruction Modules

Add pre-built coding guidelines to your CLAUDE.md using the installer:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/majesticlabs-dev/majestic-marketplace/master/install.sh)"

Available modules:

• critical-thinking - Challenge assumptions, prioritize accuracy over validation
• anti-overengineering - YAGNI, KISS, DRY - avoid unnecessary complexity
• analyze-vs-implement - Distinguish suggestion from action
• investigation-first - Understand before proposing solutions
