Open Source Management

When to use this skill

• Wants to set up a new open source project with proper governance files
• Needs help writing or improving CONTRIBUTING.md, CODE_OF_CONDUCT.md, or issue templates
• Asks about choosing an open source license (MIT, Apache 2.0, GPL, etc.)
• Wants to write or automate changelogs and release notes
• Needs help with semantic versioning decisions
• Asks about managing contributors, reviewing PRs, or triaging issues
• Wants to build or grow an open source community
• Needs a governance model (BDFL, meritocratic, foundation-backed)

• Writing application code or fixing bugs (use language-specific or clean-code skills)
• Internal/proprietary project management (use operations or product skills instead)

Key principles

1. Lower the barrier to contribute - Every friction point in the contribution process costs you potential contributors. Clear docs, good first issues, fast PR reviews, and automated checks all reduce friction. The easier it is to contribute, the more people will.
2. Document decisions, not just code - Governance, versioning policy, release cadence, and architectural decisions should be written down. Undocumented tribal knowledge is the fastest path to a project that only one person can maintain.
3. Automate the boring parts - Use CI/CD for tests, linting, changelog generation, release publishing, and CLA checks. Maintainer time is the scarcest resource in any OSS project - spend it on design decisions and community, not repetitive tasks.
4. Be explicit about expectations - Contributors need to know response time expectations, code style requirements, and the process for proposing changes. Maintainers need to set boundaries on their own availability to avoid burnout.
5. License deliberately - Your license choice determines how your project can be used, forked, and commercialized. Choose early, understand the implications, and never change licenses without careful legal and community consideration.

Common tasks

Set up a new open source project

1. LICENSE - Choose a license (see "Choose a license" task below)
2. README.md - Project name, description, install, usage, contributing link, license badge
3. CONTRIBUTING.md - Development setup, coding standards, PR process, issue guidelines
4. CODE_OF_CONDUCT.md - Adopt Contributor Covenant v2.1 (industry standard)
5. SECURITY.md - How to report vulnerabilities (never via public issues)
6. .github/ISSUE_TEMPLATE/ - Bug report and feature request templates
7. .github/PULL_REQUEST_TEMPLATE.md - PR checklist with description, testing, and breaking change sections

Always include a DCO (Developer Certificate of Origin) or CLA (Contributor License Agreement) requirement for projects that may have IP concerns.

Write a changelog

# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### Added
- New feature X for doing Y

### Changed
- Updated dependency Z to v2.0

### Fixed
- Bug where A caused B (#123)

## [1.2.0] - 2025-03-01

### Added
- Initial support for feature W

Triage issues effectively

1. Acknowledge within 48 hours - even a "thanks, we'll look at this" reduces contributor frustration
2. Label by type (bug, feature, question, documentation) and priority (critical, high, medium, low)
3. Tag good first issues - look for self-contained tasks with clear scope and mark them

   good first issue

4. Close stale issues politely after 90 days of inactivity with a bot (use

   actions/stale

   )
5. Link duplicates rather than just closing them - the reporter's wording may help future searchers

Manage releases

1. Decide the version bump using SemVer rules (see

   references/semver-releases.md

   )
2. Update CHANGELOG.md - move Unreleased items under the new version heading
3. Update version in package.json / pyproject.toml / Cargo.toml / etc.
4. Create a git tag:

   git tag -a v1.2.0 -m "Release v1.2.0"

5. Push tag:

   git push origin v1.2.0

6. CI publishes to package registry (npm, PyPI, crates.io, etc.)
7. Create GitHub Release from the tag with changelog content as body
8. Announce on community channels (Discord, Twitter, blog)

Automate steps 2-7 with tools like

release-please

,

semantic-release

, or

changesets

to eliminate human error.

Write a CONTRIBUTING.md

# Contributing to [Project Name]

Thank you for your interest in contributing!

## Code of Conduct

This project follows the [Contributor Covenant](CODE_OF_CONDUCT.md).

## How to Contribute

### Reporting Bugs
- Search existing issues first
- Use the bug report template
- Include reproduction steps, expected vs actual behavior, environment details

### Suggesting Features
- Open a discussion or feature request issue
- Explain the problem you're solving, not just the solution you want

### Submitting Code
1. Fork the repository
2. Create a feature branch from `main`
3. Make your changes following our coding standards
4. Write or update tests
5. Run the test suite locally
6. Submit a pull request

## Development Setup
[Steps to clone, install dependencies, run tests]

## Pull Request Process
- PRs require at least one maintainer review
- All CI checks must pass
- Squash commits before merging
- Update CHANGELOG.md for user-facing changes

Set up governance for a growing project

1. Write a GOVERNANCE.md defining decision-making process
2. Establish a core team with documented roles and responsibilities
3. Define RFC (Request for Comments) process for significant changes
4. Set up regular maintainer meetings (bi-weekly or monthly)
5. Create a MAINTAINERS.md listing active maintainers and their areas of ownership

Anti-patterns / common mistakes

Gotchas

1. SemVer MAJOR bump requirement is frequently underestimated - Any breaking change to a public API - including removing a previously exported function, changing a function signature, or changing behavior in a way that breaks existing consumers - requires a MAJOR version bump. Teams routinely ship breaking changes as MINOR bumps ("it's just a small change"), which breaks downstream consumers and erodes trust. When in doubt, bump MAJOR.
2. Relicensing without CLA consent from all contributors is legally risky - If contributors submitted code under MIT and you want to relicense to Apache 2.0 or AGPL, you need written consent from every contributor who owns copyrightable contributions. Even one holdout blocks the relicense. Use a CLA (Contributor License Agreement) from day one if you anticipate ever changing the license.

3. actions/stale

   closes issues contributors are actively working on - A default stale bot configuration that closes issues after 60 days of inactivity will close issues where a contributor is mid-implementation but just hasn't commented. This is a common contributor experience failure. Configure stale bots to apply a label and warn, not close automatically - require human review before closing.
4. GitHub security advisories are not automatically sent to dependents - Creating a SECURITY.md only helps if reporters use it. For vulnerabilities in published packages, you must create a GitHub Security Advisory and request a CVE to trigger automated alerts in dependent projects. Simply patching and releasing a new version without an advisory leaves most users unaware.
5. Automated changelog generation requires conventional commits from day one - Tools like

   release-please

   or

   semantic-release

   depend on conventional commit message prefixes (

   feat:

   ,

   fix:

   ,

   BREAKING CHANGE:

   ). Introducing these tools to a project with non-conventional commit history produces either empty or incorrect changelogs. Establish the commit message convention before the first release, not retroactively.
