+
+Read the current version from `pyproject.toml` (the `version` property).
+
+The bump type is: $ARGUMENTS
+
+Compute the new version by incrementing the appropriate component of the current version:
+-`patch` — increment the third number, keep major and minor (e.g. 1.7.0 → 1.7.1)
+-`minor` — increment the second number, reset patch to 0 (e.g. 1.7.0 → 1.8.0)
+-`major` — increment the first number, reset minor and patch to 0 (e.g. 1.7.0 → 2.0.0)
+
+Then perform these steps in order:
+
+1. Run `git checkout -b release/NEW_VERSION`
+2. Replace `OLD_VERSION` with `NEW_VERSION` in all of the following files:
+-`pyproject.toml` — the `version` property
+-`ably/__init__.py` — lib_version value
+ 3.Run `uv sync` to update `uv.lock` file
+4. Commit all files together with message: `chore: bump version to NEW_VERSION`
+3. Fetch merged PRs since the last release tag using:
+```
+ gh pr list --state merged --base main --json number,title,mergedAt --limit 200
+```
+ Then get the date of the last release tag with:
+```
+ git log vOLD_VERSION --format="%aI" -1
+```
+ Filter the PRs to only those merged after that tag date. Format each as:
+```
+ - Short, one sentence summary from PR title and description [#NUMBER](https://github.com/ably/ably-java/pull/NUMBER)
+```
+ If the tag doesn't exist or there are no merged PRs, use a single `-` placeholder bullet instead.
+
+4. In `CHANGELOG.md`, insert the following block immediately after the `# Change Log` heading (and its trailing blank line), before the first existing `## [` version entry:
+
+```
+## [NEW_VERSION](https://github.com/ably/ably-java/tree/vNEW_VERSION)
+
+[Full Changelog](https://github.com/ably/ably-java/compare/vOLD_VERSION...vNEW_VERSION)
+
+### What's Changed
+
+BULLETS_FROM_STEP_3
+
+```
+
+5. Commit `CHANGELOG.md` with message: `docs: update CHANGELOG for NEW_VERSION release`
+
+After completing all steps, show the user a summary of what was done. If PRs were found, list them. If the placeholder `-` was used instead, remind them to fill in the `### What's Changed` bullet points in `CHANGELOG.md` before merging.

-## Release Process
+## Release Process (Claude Code)
+
+1. Ensure that all work intended for this release has landed to `main`
+2. Run `/release patch|minor|major` in Claude Code — this creates the release branch, bumps the version in all required files, and populates the [CHANGELOG](./CHANGELOG.md) with merged PRs since the last tag automatically
+3. Review the `### What's Changed` entries in [CHANGELOG.md](./CHANGELOG.md) and adjust if needed, then commit any edits
+4. Create a release PR (ensure you include an SDK Team Engineering Lead and the SDK Team Product Manager as reviewers) and gain approvals for it, then merge that to `main`
+5. Create a tag named like `v2.0.1` and push it to GitHub - e.g. `git tag v2.0.1 && git push origin v2.0.1`
+6. Create the release on GitHub including populating the release notes
+7. Go to the [Release Workflow](https://github.com/ably/ably-python/actions/workflows/release.yml) and ask [ably/team-sdk](https://github.com/orgs/ably/teams/team-sdk) member to approve publishing to the PyPI registry
+8. Update the [Ably Changelog](https://changelog.ably.com/) (via [headwayapp](https://headwayapp.co/)) with these changes
+
+## Release Process (Manual)
 
 Releases should always be made through a release pull request (PR), which needs to bump the version number and add to the [change log](CHANGELOG.md).
