+# AI Agent Contributions
+
+This document tracks contributions made by AI coding agents to the mo2fmu project.
+
+## Purpose
+
+This file serves as a transparent record of:
+- AI-assisted development work
+- Documentation improvements by AI agents
+- Code reviews and suggestions from AI
+- Automated refactoring and improvements
+
+## Release Process
+
+This section documents the steps for creating a new release of mo2fmu.
+
+### Pre-Release Checklist
+
+Before creating a release, ensure:
+
+- [ ] All tests pass locally and in CI
+- [ ] Documentation is up to date
+- [ ] CHANGELOG.md is updated with new version
+- [ ] Version numbers are bumped in all files
+- [ ] All changes are committed and pushed
+
+### Version Bumping
+
+Update version numbers in the following files:
+
+1. **`pyproject.toml`**
+   ```toml
+   [project]
+   version = "X.Y.Z"
+   ```
+
+2. **`src/python/feelpp/mo2fmu/__init__.py`**
+   ```python
+   __version__ = "X.Y.Z"
+   ```
+
+3. **`package.json`**
+   ```json
+   "version": "X.Y.Z"
+   ```
+
+4. **`CHANGELOG.md`**
+   - Add new section for version X.Y.Z
+   - Document all changes under appropriate categories:
+     - Added
+     - Changed
+     - Deprecated
+     - Removed
+     - Fixed
+     - Security
+
+### Release Steps
+
+#### 1. Prepare the Release
+
+```bash
+# Ensure you're on main branch and up to date
+git checkout main
+git pull origin main
+
+# Update version numbers (see Version Bumping above)
+# Edit pyproject.toml, __init__.py, package.json, CHANGELOG.md
+
+# Commit version bump
+git add pyproject.toml src/python/feelpp/mo2fmu/__init__.py package.json CHANGELOG.md
+git commit -m "Bump version to X.Y.Z"
+git push origin main
+```
+
+#### 2. Create Git Tag
+
+```bash
+# Create annotated tag
+git tag -a vX.Y.Z -m "Release version X.Y.Z"
+
+# Push tag to trigger release workflow
+git push origin vX.Y.Z
+```
+
+#### 3. Automated Release (GitHub Actions)
+
+The GitHub Actions workflow (`.github/workflows/ci.yml`) automatically:
+
+1. **Builds the wheel** (`build_wheel` job)
+   - Runs code quality checks (ruff, black, flake8, mypy)
+   - Builds Python wheel using `uv build`
+   - Runs tests with coverage
+   - Uploads wheel as artifact
+
+2. **Builds documentation** (`build_docs` job)
+   - Generates Antora documentation
+   - Deploys to GitHub Pages (on main branch)
+
+3. **Creates GitHub Release** (`release` job, triggered by tags)
+   - Downloads built wheel artifact
+   - Creates GitHub release with auto-generated notes
+   - Uploads wheel and LICENSE to release
+   - Publishes to PyPI using trusted publisher (OIDC)
+
+#### 4. Verify Release
+
+After the workflow completes:
+
+1. **Check GitHub Release**: https://github.com/feelpp/mo2fmu/releases
+   - Verify release notes are correct
+   - Ensure wheel file is attached
+
+2. **Check PyPI**: https://pypi.org/project/feelpp-mo2fmu/
+   - Verify new version appears
+   - Check package metadata is correct
+
+3. **Test Installation**:
+   ```bash
+   # Test installation from PyPI
+   pip install --upgrade feelpp-mo2fmu
+   
+   # Verify version
+   python -c "import feelpp.mo2fmu; print(feelpp.mo2fmu.__version__)"
+   
+   # Test CLI
+   mo2fmu --help
+   ```
+
+4. **Check Documentation**: https://feelpp.github.io/mo2fmu
+   - Verify documentation is updated
+   - Check that version is correct
+
+### Hotfix Releases
+
+For critical bug fixes:
+
+1. Create hotfix branch from tag:
+   ```bash
+   git checkout -b hotfix/X.Y.Z+1 vX.Y.Z
+   ```
+
+2. Apply fixes and commit
+
+3. Bump version to X.Y.Z+1
+
+4. Create tag and push:
+   ```bash
+   git tag -a vX.Y.Z+1 -m "Hotfix release X.Y.Z+1"
+   git push origin vX.Y.Z+1
+   ```
+
+5. Merge back to main:
+   ```bash
+   git checkout main
+   git merge hotfix/X.Y.Z+1
+   git push origin main
+   ```
+
+### Release Cadence
+
+- **Major versions (X.0.0)**: Breaking changes, major features
+- **Minor versions (0.X.0)**: New features, significant improvements
+- **Patch versions (0.0.X)**: Bug fixes, minor improvements
+
+### Versioning Guidelines
+
+Follow [Semantic Versioning](https://semver.org/):
+
+- **MAJOR**: Incompatible API changes
+- **MINOR**: Backwards-compatible functionality additions
+- **PATCH**: Backwards-compatible bug fixes
+
+### Post-Release Tasks
+
+After a successful release:
+
+- [ ] Update AGENTS.md if AI assistance was used
+- [ ] Announce release on relevant channels
+- [ ] Monitor for issues or bug reports
+- [ ] Update documentation if needed
+
+### Rollback Procedure
+
+If a release has critical issues:
+
+1. **Mark release as pre-release** on GitHub
+2. **Yank version from PyPI** (if necessary):
+   ```bash
+   # Contact PyPI or use pypi.org interface
+   ```
+3. **Create hotfix release** with fixes
+4. **Communicate** the issue to users
+
+### Troubleshooting Release Issues

+## Guidelines for Future AI Contributions
+
+### When to Document in AGENTS.md
+
+Document AI contributions when:
+- ✅ Creating new features or significant code changes
+- ✅ Writing or rewriting documentation
+- ✅ Performing major refactoring
+- ✅ Making architectural decisions
+- ✅ Creating multiple files in a single session
+
+Do NOT document for:
+- ❌ Minor typo fixes
+- ❌ Simple one-line changes
+- ❌ Routine code reviews
+- ❌ Trivial formatting updates
+
+### Documentation Template
+
+When adding a new session, use this template:
+
+```markdown
+### Session: [Brief Description] (YYYY-MM-DD)
+
+**Agent**: [Agent Name]  
+**User**: [User Name]  
+**Branch**: [branch-name]  
+**Version**: [version if applicable]
+
+#### Work Completed
+[Detailed description of work]
+
+#### Files Modified
+[List of created/modified files]
+
+#### Impact
+[Description of impact on project]
+
+#### Quality Checks
+[List verification performed]
+```
+
+### Best Practices
+
+1. **Transparency**: Always document AI-generated code clearly
+2. **Verification**: User should review and approve AI contributions
+3. **Testing**: AI-generated code should be tested before merging
+4. **Documentation**: Keep this log updated with significant contributions
+5. **Attribution**: Credit AI assistance appropriately
+
+### Human Review Required
+
+All AI contributions require human review for:
+- Code correctness and security
+- Documentation accuracy
+- Consistency with project standards
+- Testing and validation
+- Integration with existing code
