/configure:pre-commit

Check and configure pre-commit hooks against project standards.

When to Use This Skill

Use this skill when...	Use another approach when...
Setting up or validating pre-commit hooks	Project doesn't use pre-commit framework (use git hooks directly)
Checking compliance with project standards	Just running hooks manually (use pre-commit run command)
Installing project-type-specific hooks	Hooks are already properly configured
Migrating to pre-commit framework	Simple project with no quality checks needed
Updating hook configurations for detected tools	Need to disable pre-commit entirely

Context

• Pre-commit config: !find . -maxdepth 1 -name \'.pre-commit-config.yaml\'
• Project standards: !find . -maxdepth 1 -name \'.project-standards.yaml\'
• Project type in standards: !grep -m1 "^project_type:" .project-standards.yaml
• Has terraform: !find . -maxdepth 2 \( -name '*.tf' -o -type d -name 'terraform' \) -print -quit
• Has helm: !find . -maxdepth 2 -type d -name 'helm' -print -quit
• Has package.json: !find . -maxdepth 1 -name \'package.json\'
• Has pyproject.toml: !find . -maxdepth 1 -name \'pyproject.toml\'

Parameters

Parse from $ARGUMENTS:

• --check-only: Report status without offering fixes
• --fix: Apply all fixes automatically without prompting
• --type <type>: Override project type detection (frontend, infrastructure, python)

Execution

Execute this pre-commit compliance check:

Step 1: Detect project type

1. Read .project-standards.yaml for project_type field if it exists
2. If not found, auto-detect:
   • infrastructure: Has terraform/, helm/, argocd/, or *.tf files
   • frontend: Has package.json with vue/react dependencies
   • python: Has pyproject.toml or requirements.txt
3. Apply --type flag override if provided

Step 2: Check configuration file

1. If .pre-commit-config.yaml is missing: report FAIL, offer to create from template
2. If it exists: read and parse the configuration

Step 3: Verify hook versions against latest releases

CRITICAL: Before flagging outdated hooks, verify latest releases using WebSearch or WebFetch:

1. pre-commit-hooks: GitHub releases
2. conventional-pre-commit: GitHub releases
3. biome: GitHub releases
4. ruff-pre-commit: GitHub releases
5. gitleaks: GitHub releases

Step 4: Analyze compliance

Compare existing configuration against project standards (from pre-commit-standards skill):

Required Base Hooks (All Projects):

• pre-commit-hooks v5.0.0+ with: trailing-whitespace, end-of-file-fixer, check-yaml, check-json, check-merge-conflict, check-added-large-files
• conventional-pre-commit v4.3.0+ with commit-msg stage

Frontend-specific:

• biome (pre-commit) v0.4.0+
• helmlint (if helm/ directory exists)

Infrastructure-specific:

• tflint, helmlint (gruntwork v0.1.29+)
• actionlint v1.7.7+
• helm-docs v1.14.2+
• gitleaks v8.22.1+

Python-specific:

• ruff-pre-commit v0.8.4+ (ruff, ruff-format)
• gitleaks v8.22.1+

Step 5: Generate compliance report

Print a report in this format:

Pre-commit Compliance Report
================================
Project Type: [type] ([detected|override])
Config File: .pre-commit-config.yaml ([found|missing])

Hook Status:
  [hook-name]     [version]   [PASS|WARN|FAIL] ([details])

Outdated Hooks:
  - [hook]: [current] -> [standard]

Overall: [N] issues found

Step 6: Apply fixes (if requested)

If --fix flag is set or user confirms:

1. Missing config file: Create from standard template for detected project type
2. Missing hooks: Add required hooks with standard versions
3. Outdated versions: Update rev: values to standard versions
4. Missing hook types: Add default_install_hook_types with pre-commit and commit-msg

After modification, run pre-commit install --install-hooks to install hooks.

Step 7: Update standards tracking

Update or create .project-standards.yaml:

standards_version: "2025.1"
project_type: "[detected]"
last_configured: "[timestamp]"
components:
  pre-commit: "2025.1"

Agentic Optimizations

Context	Command
Check if pre-commit installed	command -v pre-commit >/dev/null 2>&1 && echo "installed" || echo "missing"
Validate config syntax	pre-commit validate-config .pre-commit-config.yaml 2>&1
List configured hooks	grep -E '^\s+- id:' .pre-commit-config.yaml 2>/dev/null | sed 's/.*id:[[:space:]]*//'
Check hook versions	pre-commit autoupdate --freeze 2>&1
Quick compliance check	/configure:pre-commit --check-only
Auto-fix configuration	/configure:pre-commit --fix

Flags

Flag	Description
--check-only	Report status without offering fixes
--fix	Apply all fixes automatically without prompting
--type <type>	Override project type detection (frontend, infrastructure, python)

Error Handling

• No git repository: Warn but continue (pre-commit still useful)
• Invalid YAML: Report parse error, offer to replace with template
• Unknown hook repos: Skip (do not remove custom hooks)
• Permission errors: Report and suggest manual fix
