Claude Night Market

A plugin marketplace for Claude Code, Anthropic's agentic coding tool.

Night Market extends Claude Code with 23 plugins covering git workflows, code review, spec-driven development, architecture selection, codebase visualization, autonomous agents, multi-LLM delegation, ML-enhanced scoring, and multi-source research. 161 skills, 146 slash commands, and 50 agents. Each plugin installs independently.

Night Market skills in action

Quick Start

Requires Claude Code 2.1.16+ and Python 3.9+ for hooks. See Requirements for details.

# Add the marketplace
/plugin marketplace add athola/claude-night-market

# Install plugins you need
/plugin install sanctum@claude-night-market    # Git workflows
/plugin install pensive@claude-night-market    # Code review
/plugin install spec-kit@claude-night-market   # Spec-driven dev

# Use them
/prepare-pr                                    # Prepare a pull request
/full-review                                   # Run code review

Alternative: Install via npx with npx skills add athola/claude-night-market (installs all plugins at once).

After installation, run claude --init for one-time setup.

Note: If the Skill tool is unavailable, read skill files directly at plugins/{plugin}/skills/{skill-name}/SKILL.md.

opkg (OpenPackage)

# Install specific plugins
opkg i gh@athola/claude-night-market --plugins sanctum

# Plugins that depend on shared runtime skills (e.g. attune, conjure)
# automatically pull packages/core as a dependency

See the Installation Guide for detailed setup options.

Architecture

23 plugins organized in four layers. Domain specialists depend on utility plugins, which depend on foundation plugins, which depend on the meta layer.
