Installation

Via GitHub Package (Recommended)

Install the plugin as an npm package from GitHub Packages. This is the easiest way to keep all your projects up to date.

1. Authenticate with GitHub Packages (one-time setup):

# Create a Personal Access Token (PAT) with read:packages scope at
# https://github.com/settings/tokens, then:
npm login --scope=@cure-consulting-group --registry=https://npm.pkg.github.com

Or add to your project's .npmrc:

@cure-consulting-group:registry=https://npm.pkg.github.com
//npm.pkg.github.com/:_authToken=${GITHUB_TOKEN}

2. Install in your project:

npm install @cure-consulting-group/product-engineering-skills

The postinstall script automatically:

  • Symlinks the package to ~/.claude/plugins/ProductEngineeringSkills
  • Registers the plugin in ~/.claude/settings.json

All 80 skills, 39 agents, 4 personas, hooks, rules, and output styles are immediately available.

3. Enable auto-updates with Dependabot (recommended):

Add .github/dependabot.yml to your project (or run setup.sh which does this automatically):

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "daily"
    allow:
      - dependency-name: "@cure-consulting-group/product-engineering-skills"
    labels:
      - "dependencies"
      - "skills-update"
    commit-message:
      prefix: "chore"
      include: "scope"

Dependabot will open a PR in your project whenever a new version is published. Merge it and every agent on that project gets the updated skills.

4. Manual update:

npm update @cure-consulting-group/product-engineering-skills

As a Claude Code Plugin (Manual)

# Load the plugin during a session
claude --plugin-dir /path/to/ProductEngineeringSkills

# Or for development/testing
claude --plugin-dir ./ProductEngineeringSkills

Once loaded, all skills are available as namespaced commands:

/cure-product-engineering:sdlc
/cure-product-engineering:feature-audit
/cure-product-engineering:android-feature-scaffold
/cure-product-engineering:incident-response
/cure-product-engineering:accessibility-audit

Hooks, agents, rules, output styles, and MCP servers are all included automatically.

Setup Script (Antigravity & Other Projects)

The fastest way to onboard any project:

# From the target project directory
/path/to/ProductEngineeringSkills/setup.sh

# Or specify the project path
/path/to/ProductEngineeringSkills/setup.sh /path/to/antigravity-app

# Install globally for ALL projects
/path/to/ProductEngineeringSkills/setup.sh --global

# Legacy mode (just copy skills, no hooks/agents)
/path/to/ProductEngineeringSkills/setup.sh --legacy

The setup script will:

  1. Clone/update the plugin to ~/.claude/plugins/
  2. Detect your project type (Android/iOS/Web/Firebase)
  3. Install only the relevant path-specific rules
  4. Create a project CLAUDE.md with skill references
  5. Add .claude/settings.local.json to .gitignore

Via Marketplace

# Add the Cure Consulting marketplace
claude marketplace add https://github.com/Cure-Consulting-Group/ProductEngineeringSkills/marketplace.json

# Install the plugin
claude plugin install cure-product-engineering

Legacy Method (Copy Commands)

Copy the claude-commands/ files into your project's .claude/commands/ directory:

cp claude-commands/*.md /path/to/your/project/.claude/commands/

Then use them as slash commands:

/sdlc — Generate SDLC artifacts
/android-feature-scaffold — Scaffold an Android feature module
/feature-audit — Audit a completed feature

Using with Google Gemini

Import the .skill files from gemini skills/ into your Gemini workspace. Each .skill file is a ZIP archive containing:

  • SKILL.md — The main skill definition
  • references/ — Supporting documents and templates

Recurring Automation (Loops & Routines)

The library ships a standard maintenance loop (self-provisioned to .claude/loop.md on first session start — run bare /loop to use it), Recurring Mode sections in the goal-shaped skills (finops, burn-rate-tracker, investor-reporting, security-review, and others), and copy-paste cloud-routine recipes in docs/AUTOMATION.md. Library upkeep cadence: docs/MAINTENANCE.md. Mechanism selection and unattended-run guardrails: /cure-product-engineering:engagement-automation.

Hooks (Multi-Layer Automated Enforcement)

The plugin ships command and prompt hooks across 9 event types: SessionStart, PreCompact, PostCompact, ConfigChange, PostToolUseFailure, UserPromptSubmit, PreToolUse, Stop, SubagentStop. Highlights: a Stop-hook quality gate (blocks "done" without verification), a PreToolUse static security guard on skill/agent/persona files, and a ConfigChange audit trigger when skill files change mid-session.

New in v4.0: Hooks now suggest and auto-trigger agents based on context. Every code edit, test run, deployment, and PR action recommends the most relevant agent(s).
