github-hooks

name	github-hooks
description	Set up local Git hooks for pre-commit validation (lint, format, tests, secrets). Integrates with mern-scaffold, nean-scaffold, and iOS projects.
argument-hint	[--platform mern|nean|ios] [--no-secrets] [--no-tests]
allowed-tools	Bash, Write, Read, Glob, Grep

Purpose

Install local Git hooks to catch issues before commits reach the remote. Complements github-secure by shifting checks left.

Designed to work with: /mern-scaffold, /mern-kit, /nean-scaffold, /nean-kit, and iOS projects.

Arguments

• --platform <p> — Target platform: mern, nean, or ios (auto-detected if not specified)
• --no-secrets — Skip secret scanning hook
• --no-tests — Skip pre-push test hook

Platform detection

If --platform not specified:

• Detect nx.json → NEAN
• Detect pnpm-workspace.yaml or turbo.json → MERN
• Detect project.yml (XcodeGen) or Package.swift or *.xcodeproj → iOS

What gets created

MERN (using Husky + lint-staged + pnpm)

.husky/
├── pre-commit        # Lint + format staged files
├── commit-msg        # Validate commit message format
└── pre-push          # Run tests before push

.lintstagedrc.json    # Lint-staged configuration
.commitlintrc.json    # Commit message rules
.gitleaks.toml        # Secret scanning config
package.json          # Updated with husky + lint-staged + commitlint

NEAN (using Husky + lint-staged + npm/Nx)

.husky/
├── pre-commit        # Lint + format staged files (via Nx)
├── commit-msg        # Validate commit message format
└── pre-push          # Run affected tests before push

.lintstagedrc.json    # Lint-staged configuration (Nx-aware)
.commitlintrc.json    # Commit message rules
.gitleaks.toml        # Secret scanning config
package.json          # Updated with husky + lint-staged + commitlint

iOS (using git hooks directly)

.githooks/
├── pre-commit        # SwiftLint + SwiftFormat on staged files
├── commit-msg        # Validate commit message format
└── pre-push          # Run tests before push

scripts/
└── install-hooks.sh  # Hook installation script

Hooks installed

pre-commit

• Lint staged files (ESLint/SwiftLint)
• Format staged files (Prettier/SwiftFormat)
• Check for secrets (gitleaks)
• Block commits with errors

commit-msg

• Enforce conventional commits format
• Validate message length
• Check for required prefixes

pre-push

• Run test suite (NEAN: affected tests only for speed)
• Block push if tests fail
• Optional: run full build

Workflow

1. Detect or specify platform
2. Install hook dependencies
3. Create hook scripts
4. Configure hook behavior
5. Verify hooks work with test commit

Secret scanning

Uses gitleaks to detect:

• API keys
• Passwords
• Tokens
• Private keys
• Connection strings

MERN integration notes

When used after /mern-scaffold:

• Detects existing pnpm workspace and turbo config
• Adds dependencies to root package.json
• Hooks run the same quality gates as CI (lint, format, test)
• Complements the existing ci.yml workflow

NEAN integration notes

When used after /nean-scaffold:

• Detects existing Nx workspace (nx.json)
• Adds dependencies to root package.json (npm)
• Pre-commit runs npx nx affected --target=lint on staged files
• Pre-push runs npx nx affected --target=test
• Uses Nx's intelligent caching for faster hook execution
• Complements the existing ci.yml workflow

iOS integration notes

When used after /ios-scaffold:

• Detects project.yml (XcodeGen), Package.swift, or *.xcodeproj
• Creates .githooks/ directory with shell scripts
• Pre-commit runs SwiftLint + SwiftFormat on staged .swift files
• Pre-push runs xcodebuild test
• Includes scripts/install-hooks.sh for team onboarding
• Complements the existing ci.yml workflow

Output

• Hooks installed
• Dependencies added
• Test commit instructions
• Remind to run /github-secure for repository-level security
