Extend Claude Code with custom skills, commands, hooks, and agents for multi-agent orchestration, git pattern extraction, prompt optimization, and workflow automation. Includes tools for creating, testing, and refining custom components.
Generate multiple response variants with probability scores for any request
Extract cross-session patterns from git history and handoffs, recommend artifacts (skill/rule/hook/agent) based on frequency.

Generate a new Claude Code sub-agent configuration file from a description
Guide for coordinating multiple Claude Code instances as a team using Agent Teams. Covers TeammateTool operations, spawn backends, communication, task coordination, hooks, and orchestration patterns. Use when building multi-agent workflows requiring inter-agent communication.
Use when creating or developing, before writing code or implementation plans - refines rough ideas into fully-formed designs through collaborative questioning, alternative exploration, and incremental validation. Don't use during clear 'mechanical' processes
Extract patterns from git history and session files, recommend artifacts (skill/rule/hook/agent) based on frequency thresholds
Forces adversarial reasoning before committing to decisions. Triggers on architectural choices, approach selection, and planning phases to prevent premature commitment bias.
Use when reviewing brainstorms, plans, or PRDs for clarity and readiness before next workflow phase. Assesses documents for vagueness, gaps, and YAGNI violations.

The Majestic marketplace where we share our workflows.
New here? Check out the Marketplace Tutorial for an interactive walkthrough.
Coding is no longer the bottleneck. Planning, review, and learning loops matter more than syntax. Each feature makes the next one easier to build.
| 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.
Run the installer:
curl -fsSL https://raw.githubusercontent.com/majesticlabs-dev/majestic-marketplace/master/install.sh | bash
This gives you options to:
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}
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/skills/ and ~/.codex/prompts/~/.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.
