Command	Description
`pre-commit install`	Install git hooks
`pre-commit run --all-files`	Run all hooks on all files
`pre-commit autoupdate`	Update hooks to latest versions
`pre-commit run <hook-id>`	Run specific hook

Workflow Routing

Workflow	Trigger	File
Setup	"setup pre-commit", "initialize hooks", "create config"	`Workflows/Setup.md`
AddHooks	"add hook", "add linting", "add formatter", "add security"	`Workflows/AddHooks.md`
Troubleshoot	"fix pre-commit", "hook failing", "debug hooks"	`Workflows/Troubleshoot.md`
CIIntegration	"CI pipeline", "GitHub Actions", "GitLab CI"	`Workflows/CIIntegration.md`
CustomHook	"create custom hook", "local hook", "write hook"	`Workflows/CustomHook.md`

Documentation

Document	Purpose
`QuickStartGuide.md`	Installation and first-time setup
`HooksReference.md`	Comprehensive hook catalog by language/purpose
`ConfigurationGuide.md`	Advanced configuration options
`SecurityHooks.md`	Secret detection and security scanning

Tools

Tool	Purpose
`Tools/PreCommitManager.ts`	CLI for managing pre-commit configurations
`Tools/HookGenerator.ts`	Generate .pre-commit-config.yaml templates
`Tools/HookValidator.ts`	Validate hook configurations

Examples

Example 1: Setup pre-commit for a new project

User: "Setup pre-commit for my Python project"
→ Invokes Setup workflow
→ Creates .pre-commit-config.yaml with Python hooks (black, isort, flake8)
→ Runs pre-commit install

Example 2: Add Terraform hooks

User: "Add Terraform validation hooks"
→ Invokes AddHooks workflow
→ Adds terraform_fmt, terraform_validate, terraform_docs hooks
→ Configures tflint and checkov integration

Example 3: Add security scanning

User: "Add secret detection to pre-commit"
→ Invokes AddHooks workflow
→ Adds gitleaks, detect-secrets, trufflehog hooks
→ Configures appropriate exclusion patterns

Example 4: Debug failing hook

User: "My eslint pre-commit hook is failing"
→ Invokes Troubleshoot workflow
→ Checks hook configuration and dependencies
→ Provides fix recommendations

Supported Hook Categories

Python: black, isort, flake8, mypy, bandit, pyupgrade
JavaScript/TypeScript: prettier, eslint, biome
Infrastructure: terraform, terragrunt, helm, kustomize
Kubernetes: kubeconform, kubeval, checkov
Security: gitleaks, detect-secrets, trufflehog, trivy
General: yamllint, jsonlint, shellcheck, markdownlint
