+# Release Process
+
+This document describes how to publish a new version of `weaver-kernel` to PyPI.
+
+## Prerequisites
+
+- Push access to the `dgenio/agent-kernel` repository.
+- Trusted Publisher configured on PyPI for this repository
+  (see [Trusted Publisher setup](#trusted-publisher-setup) below).
+
+## Steps
+
+### 1. Bump the version
+
+Update the `version` field in `pyproject.toml`:
+
+```toml
+[project]
+version = "0.3.0"
+```
+
+### 2. Update the changelog
+
+Add a new section to `CHANGELOG.md` under `## [Unreleased]`, then rename it
+to the new version with today's date:
+
+```markdown
+## [0.3.0] - 2026-04-01
+
+### Added
+- ...
+
+### Fixed
+- ...
+```
+
+### 3. Commit and tag
+
+```bash
+git add pyproject.toml CHANGELOG.md
+git commit -m "release: v0.3.0"
+git tag v0.3.0
+git push origin main --tags
+```
+
+### 4. CI takes over
+
+Pushing the `v*` tag triggers `.github/workflows/publish.yml`, which:
+
+1. Runs the full CI suite (`make ci` equivalent) as a gate.
+2. Builds the sdist and wheel with `python -m build`.
+3. Publishes to PyPI using Trusted Publisher (OIDC — no API tokens stored).
+
+Monitor the workflow run at:
+<https://github.com/dgenio/agent-kernel/actions/workflows/publish.yml>
+
+### 5. Verify
+
+```bash
+pip install weaver-kernel==0.3.0
+```
+
+## Trusted Publisher Setup
+
+Trusted Publisher uses OpenID Connect (OIDC) so the GitHub Actions workflow can
+publish to PyPI without storing API tokens as secrets.
+
+To configure it (one-time setup):
+
+1. Go to <https://pypi.org/manage/project/weaver-kernel/settings/publishing/>.
+2. Add a new publisher:
+   - **Owner**: `dgenio`
+   - **Repository**: `agent-kernel`
+   - **Workflow name**: `publish.yml`
+   - **Environment**: `pypi`
+3. Save. The `publish.yml` workflow will now authenticate automatically.
+
+## Version scheme
+
+This project follows [Semantic Versioning](https://semver.org/):
+
+- **PATCH** (0.2.x): bug fixes, documentation updates.
+- **MINOR** (0.x.0): new features, backward-compatible changes.
+- **MAJOR** (x.0.0): breaking API changes.
