Pre-commit SDLC Governance Hooks

A collection of pre-commit hooks for software development lifecycle (SDLC) governance. These hooks are designed to enforce best practices and standardize the software development process, ensuring consistency and quality across projects.

Overview

This repository provides a set of hooks that integrate with the pre-commit framework to help maintain code quality and governance standards throughout your development workflow. Whether you choose to install the hooks remotely or locally, they are flexible and configurable to meet your project’s requirements.

Using These Hooks

Remote Hooks

To use the remote hooks, add the following configuration to your .pre-commit-config.yaml file:

repos:
- repo: https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks
  rev: v1.0.0 # Replace with the desired version of the hooks

To update the remote hooks in your configuration, run:

pre-commit autoupdate --repo https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks

Local Installation

You can also install the hooks locally using pip:

pip install pre-commit-sdlcgov-hooks

Then, reference them in your .pre-commit-config.yaml file as follows:

# .pre-commit-config.yaml
repos:
- repo: local
  # No rev is needed here

To update the hooks when installed locally, simply update the package using pip. Note that remote hook referencing is the preferred method.

Premises

Although these hooks are configurable to some extent, they are based on the following premises:

• Commit Message Length: Commit message subjects must be at least 4 characters long and no longer than 70 characters.

• Issue Branch Naming: Issue branches should follow the format ISSUENUM-issue[-at-PROJECTNAME], where:

  • ISSUENUM represents the issue number.
  • The optional PROJECTNAME specifies the project name, used when referencing an external issue.

  Examples of valid issue branch names include:

  • 123-issue
  • 456-issue-at-owner/repo

Available Hooks

pre-commit Stage

safety-guard

This hook prevents a commit if any staged changes include a specific safety guard phrase (default: DO NOT COMMIT). This is particularly useful to ensure that temporary or debugging code is not accidentally committed.

The guard phrase can be customized by passing a new phrase with the --guard-phrase argument:

# .pre-commit-config.yaml
repos:
- repo: https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks
  rev: # ...
  hooks:
  - id: safety-guard
    args:
    - "--guard-phrase"
    - "DO NOT COMMIT"

enforce-committing-to-issue

This hook enforces that commits are made only on issue branches, protecting against accidental commits to branches such as development or production. It is particularly useful in workflows where changes are linked to specific issues and later merged via pull or merge requests.

Example configuration:

# .pre-commit-config.yaml
repos:
- repo: https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks
  rev: # ...
  hooks:
  - id: enforce-committing-to-issue

Skipping this check

If it is necessary to bypass this check (e.g., during a manual merge when automation is not feasible), use the SKIP environment variable:

SKIP=enforce-committing-to-issue

For instance:

SKIP=enforce-committing-to-issue git commit -m "..."

prepare-commit-msg Stage

ellipsize-subject

This hook automatically shortens commit subjects that exceed a specified length by adding an ellipsis. The original subject is preserved in the commit message body. The default maximum subject length is 70 characters, but you can adjust this with the --length argument.

# .pre-commit-config.yaml
repos:
- repo: https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks
  rev: # ...
  hooks:
  - id: ellipsize-subject
    args:
    - "--length"
    - "70"

add-gl-issue-ref

This hook automatically adds a reference to the current GitLab issue in the commit message if no GitLab issue reference is detected. The reference is inferred from the active issue branch name. If any issue reference already exists in the commit message, no additional reference is added.

# .pre-commit-config.yaml
repos:
- repo: https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks
  rev: # ...
  hooks:
  - id: add-gl-issue-ref

For workflows where it is essential that the commit message includes the active issue reference, combine this hook with enforce-gl-issue-ref.

commit-msg Stage

enforce-subject-length

This hook ensures that the commit message subject adheres to the defined length constraints: a minimum of 4 characters and a maximum of 70 characters (by default). The hook will fail if the subject does not meet these criteria. Similar to the ellipsize-subject hook, the maximum length can be adjusted with the --length argument.

# .pre-commit-config.yaml
repos:
- repo: https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks
  rev: # ...
  hooks:
  - id: enforce-subject-length
    args:
    - "--length"
    - "70"

enforce-gl-issue-ref

This hook will fail if no GitLab issue is referenced in the commit message. When working from a standardized issue branch, the commit message must include a reference to the corresponding issue. This helps prevent errors such as typographical mistakes or committing to the wrong branch.

# .pre-commit-config.yaml
repos:
- repo: https://gitlab.com/Kencho1/pre-commit-sdlcgov-hooks
  rev: # ...
  hooks:
  - id: enforce-gl-issue-ref
