Claude Night Market

Claude Code plugins for software engineering workflows.

16 plugins providing 122 skills, 97 commands, and 41 agents for git operations, code review, spec-driven development, and issue management. Each plugin installs independently.

Quick Start

# 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
opkg i gh@athola/claude-night-market --plugins pensive,conserve

# 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

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

How the Layers Work

Governance and quality. imbue enforces TDD via a PreToolUse hook that verifies test files before allowing implementation writes. Quality gates in /create-skill and /create-command halt execution when tests fail. imbue:rigorous-reasoning requires step-by-step logic checks before tool execution.

Security and sessions. leyline manages OAuth flows with local token caching. conserve auto-approves safe commands while blocking destructive operations. sanctum isolates named sessions. Agents can run in worktree isolation to prevent filesystem conflicts during parallel execution.

Maintenance. /update-ci reconciles pre-commit hooks and GitHub Actions with code changes. abstract's homeostatic monitor tracks skill stability and auto-triggers improvement agents when degradation is detected. It creates GitHub issues for human review. /fix-workflow repairs failed runs by analyzing previous errors.

Cross-session state. attune, spec-kit, and sanctum persist state across sessions via CLAUDE_CODE_TASK_LIST_ID. GitHub Discussions serve as a second persistence layer: leyline retrieves Decisions at session start, attune publishes war-room deliberations, memory-palace promotes evergreen knowledge, and imbue links scope-guard deferrals to companion discussions.

Risk classification. leyline:risk-classification provides 4-tier task gating. GREEN and YELLOW tasks use heuristic matching. RED and CRITICAL tasks escalate to war-room-checkpoint for expert deliberation.

Requirements

Claude Code 2.1.16+ (2.1.32+ for agent teams, 2.1.38+ for security features, 2.1.63 latest tested)
Python 3.9+ for hooks (macOS ships 3.9.6). Plugin packages may target 3.10+ via virtual environments, but all hook code must be 3.9-compatible. See the Plugin Development Guide for compatibility rules.

Plugin Development

make create-plugin NAME=my-plugin
make validate
make lint && make test
