Compliance Checking

Required Base Hooks (All Projects)

Every FVH repository MUST have these hooks:

1. pre-commit-hooks (v5.0.0+)

   • trailing-whitespace
   • end-of-file-fixer
   • check-yaml
   • check-json
   • check-merge-conflict
   • check-added-large-files

2. conventional-pre-commit (v4.3.0+)

   • conventional-pre-commit in commit-msg stage

Status Levels

Status	Meaning
PASS	Hook present with compliant version
WARN	Hook present but version outdated
FAIL	Required hook missing
SKIP	Hook not applicable for project type

Version Comparison

When checking versions:

• Exact match or newer: PASS
• Older by patch version: WARN (functional but should update)
• Missing entirely: FAIL (must add)

Exclusion Patterns

Frontend Apps

Exclude Kubernetes/Helm templates from YAML/prettier checks:

exclude: ^(helm/templates/|skaffold/|k8s/).*\.ya?ml$

Infrastructure

Exclude ArgoCD and Helm templates:

exclude: argocd/.*templates/|helm/[^/]+/templates/

Python

No special exclusions needed for standard Python projects.

Installation

After configuring .pre-commit-config.yaml:

pre-commit install
pre-commit install --hook-type commit-msg

Or simply:

pre-commit install --install-hooks

Updating

To update all hooks to latest versions:

pre-commit autoupdate

Then verify versions match FVH standards.
