Scripts Directory Configuration Skill

This skill provides templates and validation logic for /scripts directory configuration in MetaSaver monorepos.

Purpose

Manage /scripts directory to:

• Automate environment setup (setup-env.js, setup-npmrc.js)
• Provide utility scripts for deployment and development
• Ensure cross-platform compatibility (Windows, macOS, Linux)
• Standardize error handling and documentation

Usage

This skill is invoked by the scripts-agent when:

• Creating new /scripts directory
• Auditing existing scripts directory configurations
• Validating scripts against standards

Templates

Standard script templates are located at:

templates/setup.sh.template

The 4 /scripts Standards

Rule 1: Setup Scripts (CRITICAL)

Required scripts for library repositories (multi-mono):

Required scripts for consumer repositories:

Exemptions:

• metasaver-marketplace - Template repository, does not require setup scripts

Validation:

# Skip metasaver-marketplace (template repo)
if [ "$REPO_NAME" = "metasaver-marketplace" ]; then
  echo "Skipping setup script validation for template repository"
  exit 0
fi

# Library repos (multi-mono)
if [ "$REPO_TYPE" = "library" ]; then
  [ -f "scripts/setup-env.js" ] || echo "VIOLATION: Missing setup-env.js"
  [ -f "scripts/setup-npmrc.js" ] || echo "VIOLATION: Missing setup-npmrc.js"
  [ -f "scripts/clean-and-build.sh" ] || echo "VIOLATION: Missing clean-and-build.sh"
fi

# Consumer repos
if [ "$REPO_TYPE" = "consumer" ]; then
  [ -f "scripts/setup-env.js" ] || echo "VIOLATION: Missing setup-env.js"
  [ -f "scripts/setup-npmrc.js" ] || echo "VIOLATION: Missing setup-npmrc.js"
  [ -f "scripts/clean-and-build.sh" ] || echo "VIOLATION: Missing clean-and-build.sh"
  [ -f "scripts/back-to-prod.sh" ] || echo "VIOLATION: Missing back-to-prod.sh"
  [ -f "scripts/use-local-packages.sh" ] || echo "VIOLATION: Missing use-local-packages.sh"
  [ -f "scripts/killport.sh" ] || echo "VIOLATION: Missing killport.sh"
fi

Rule 2: Cross-Platform Support (CRITICAL)

Requirements for Node.js scripts:

• ALWAYS USE path module for all file paths (do not hardcode slashes)
• USE process.platform for OS-specific logic
• INCLUDE Shebang: #!/usr/bin/env node

Example:

const path = require("path");
const envPath = path.join(__dirname, "..", ".env"); // CORRECT - uses path module
// const envPath = '../.env';  // INCORRECT - avoid hardcoded paths

Validation:

# Verify path module usage
grep -q "require.*path" scripts/*.js || echo "VIOLATION: path module must be used"

# Check for hardcoded paths (should not exist)
grep -E "\.\.\/|\.\.\\\\|\.\/" scripts/*.js && echo "WARNING: Hardcoded paths detected - use path module instead"

Rule 3: Error Handling

Required error handling patterns:

• try-catch blocks for async operations
• console.log feedback for success/failure
• process.exit(1) on errors
• Descriptive error messages

Example:

try {
  // Operation
  console.log("Success: Operation completed");
} catch (error) {
  console.error("Error: Operation failed -", error.message);
  process.exit(1);
}

Validation:

# Check for error handling
grep -q "try.*catch" scripts/*.js || echo "WARNING: No try-catch blocks found"
grep -q "process.exit" scripts/*.js || echo "WARNING: No process.exit calls found"

Rule 4: Documentation

Required documentation elements:

• Shebang line (#!/usr/bin/env node or #!/usr/bin/env bash)
• JSDoc comments for Node.js scripts
• Usage examples in comments

Note: scripts/README.md is NOT required - scripts should be self-documenting via inline JSDoc and comments.

Validation:

# Check for shebang in Node.js scripts
head -n1 scripts/*.js | grep -q "#!/usr/bin/env node" || echo "VIOLATION: Missing shebang"

# Check for shebang in shell scripts
head -n1 scripts/*.sh | grep -q "#!/bin/bash" || echo "VIOLATION: Missing shebang"

Validation

To validate /scripts directory:

1. Detect repository type (library vs consumer)
2. Check that /scripts exists at repository root
3. Verify required scripts present (Rule 1)
4. Check cross-platform patterns (Rule 2)
5. Verify error handling (Rule 3)
6. Check documentation (Rule 4)
7. Report violations

Validation Approach

# Check directory exists at root
[ -d "scripts" ] || echo "VIOLATION: /scripts directory not found at root"

# Validate against 4 standards (see rules above)
# Report only violations

Repository Type Considerations

• Library Repos (@metasaver/multi-mono): Core setup scripts only
• Consumer Repos: All setup scripts + registry switching + port management
• All Repos: Scripts must be at root /scripts directory only

Best Practices

1. ALWAYS PLACE scripts at repository root /scripts (use subdirectories for monorepo workspaces only)
2. USE Node.js for cross-platform file operations (setup-env.js, setup-npmrc.js)
3. USE bash for build/deploy scripts with proper error handling
4. INCLUDE chmod +x instructions for shell scripts
5. USE JSDoc and inline comments instead of separate README.md
6. TEST scripts on multiple platforms when possible
7. ALWAYS USE path module consistently (avoid hardcoded paths)
8. RE-AUDIT after making changes

Integration

This skill integrates with:

• Repository type provided via scope parameter. If not provided, use /skill scope-check
• /skill audit-workflow - Bi-directional comparison workflow
• /skill remediation-options - Conform/Update/Ignore choices
• package-scripts-agent - For npm scripts that invoke /scripts utilities
