End-of-central-directory record:
-------------------------------

  Zip archive file size:                      1981 (00000000000007BDh)
  Actual end-cent-dir record offset:          1959 (00000000000007A7h)
  Expected end-cent-dir record offset:        1959 (00000000000007A7h)
  (based on the length of the central directory and its expected offset)

  This zipfile constitutes the sole disk of a single-part archive; its
  central directory contains 4 entries.
  The central directory is 385 (0000000000000181h) bytes long,
  and its (expected) offset in bytes from the beginning of the zipfile
  is 1574 (0000000000000626h).

  Enforce commit message conventions and code quality standards.
  Prevent bad commits before they happen.

# Commit Validator v1.8.0

Keep your Git history clean and meaningful.

## Features

- Conventional commit enforcement
- Ticket/issue linking
- Scope validation
- Breaking change detection
- Custom rule engine
- Team-wide consistency

## Architecture

```
commit-validator/
├── SKILL.md
└── scripts/
    └── commit-msg.sh   # Core validator implementation
```

## Installation

Installs a commit-msg hook in your repository.

## Configuration

```yaml
# config.yaml
format:
  pattern: "^(feat|fix|docs|style|refactor|test|chore)(\\(.+\\))?!?: .{10,72}$"
  require_scope: false
  require_issue: true
  issue_pattern: "[A-Z]+-[0-9]+"

validation:
  max_subject_length: 72
  max_body_length: 500
  require_body: false
  allowed_types:
    - feat
    - fix
    - docs
    - style
    - refactor
    - test
    - chore
```

## Usage

```bash
/commit-validator install
/commit-validator check "feat: add new feature"
/commit-validator configure
```

## Quick Start

**To install the commit validator, simply run:**

```bash
# Copy hook to .git/hooks/
cp scripts/commit-msg.sh .git/hooks/commit-msg
chmod +x .git/hooks/commit-msg
```

**That's it!** The hook validates commit messages automatically.

## Hook Behavior

The validator enforces:
- Conventional commit format
- Maximum subject length
- Team activity logging

*Better commits, better codebase*

#!/bin/bash
# Commit Validator - Commit message validation
# Enforce commit message conventions and code quality standards

COMMIT_MSG_FILE=$1
COMMIT_MSG=$(cat "$COMMIT_MSG_FILE")

# Validate conventional commit format
if ! echo "$COMMIT_MSG" | grep -qE "^(feat|fix|docs|style|refactor|test|chore)"; then
    echo "Error: Commit message must follow conventional commits format"
    exit 1
fi

 This is a sample project for testing commit validation.
 
+## Commit messages
+
+Commit messages must follow the rules in `config.yaml`: use an allowed
+Conventional Commit type, keep the subject at 72 characters or fewer, and
+include an issue key such as `APP-123`.
+
+```text
+feat(auth): add token refresh APP-123
+```
+
+Install the tracked Git hook once per clone:
+
+```bash
+./project/scripts/install-hooks.sh
+```
+
+The configuration file uses JSON syntax, which is also valid YAML 1.2, so the
+validator can load it without a third-party dependency.

 ## Commit messages
 
-Commit messages must follow the rules in `config.yaml`: use an allowed
-Conventional Commit type, keep the subject at 72 characters or fewer, and
-include an issue key such as `APP-123`.
+Commit messages must follow the rules in `config.yaml`:
+
+- Use an allowed Conventional Commit type and, optionally, one non-empty scope.
+- Write a description of at least 10 characters.
+- Keep the complete subject at 72 characters or fewer.
+- Include a standalone issue key such as `APP-123`.
+- Keep the optional commit body at 500 characters or fewer in total.
 
 ```text
 feat(auth): add token refresh APP-123
 ```
 
-Install the tracked Git hook once per clone:
+This validation is a local Git hook, not server-wide enforcement. Install it once
+in every clone where commits are created:
 
 ```bash
 ./project/scripts/install-hooks.sh
 ```
 
+Git hooks can be bypassed with `git commit --no-verify`, so protected branches
+should also use server-side validation when enforcement cannot be optional.
+
 The configuration file uses JSON syntax, which is also valid YAML 1.2, so the
 validator can load it without a third-party dependency.

 This is a sample project for testing commit validation.
 
+## Commit messages
+
+Commit messages must follow the rules in `config.yaml`: use an allowed
+Conventional Commit type, keep the subject at 72 characters or fewer, and
+include an issue key such as `APP-123`.
+
+```text
+feat(auth): add token refresh APP-123
+```
+
+Install the tracked Git hook once per clone:
+
+```bash
+./project/scripts/install-hooks.sh
+```
+
+The configuration file uses JSON syntax, which is also valid YAML 1.2, so the
+validator can load it without a third-party dependency.

     1	# Sample Project
     2	
     3	This is a sample project for testing commit validation.
     4	
     5	## Commit messages
     6	
     7	Commit messages must follow the rules in `config.yaml`: use an allowed
     8	Conventional Commit type, keep the subject at 72 characters or fewer, and
     9	include an issue key such as `APP-123`.
    10	
    11	```text
    12	feat(auth): add token refresh APP-123
    13	```
    14	
    15	Install the tracked Git hook once per clone:
    16	
    17	```bash
    18	./project/scripts/install-hooks.sh
    19	```
    20	
    21	The configuration file uses JSON syntax, which is also valid YAML 1.2, so the
    22	validator can load it without a third-party dependency.

 ## Commit messages
 
-Commit messages must follow the rules in `config.yaml`: use an allowed
-Conventional Commit type, keep the subject at 72 characters or fewer, and
-include an issue key such as `APP-123`.
+Commit messages must follow the rules in `config.yaml`:
+
+- Use an allowed Conventional Commit type and, optionally, one non-empty scope.
+- Write a description of at least 10 characters.
+- Keep the complete subject at 72 characters or fewer.
+- Include a standalone issue key such as `APP-123`.
+- Keep the optional commit body at 500 characters or fewer in total.
 
 ```text
 feat(auth): add token refresh APP-123
 ```
 
-Install the tracked Git hook once per clone:
+This validation is a local Git hook, not server-wide enforcement. Install it once
+in every clone where commits are created:
 
 ```bash
 ./project/scripts/install-hooks.sh
 ```
 
+Git hooks can be bypassed with `git commit --no-verify`, so protected branches
+should also use server-side validation when enforcement cannot be optional.
+
 The configuration file uses JSON syntax, which is also valid YAML 1.2, so the
 validator can load it without a third-party dependency.
