release

Release process for Kimi Code CLI packages. Tags are pushed without a v prefix and follow one of these patterns (matched by .github/workflows/release-*.yml):

The Rust implementation (kagent) lives in a separate repository and is not released from here.

Steps

1. Understand the automation. Read AGENTS.md and .github/workflows/release*.yml so you know what each release workflow expects before changing any versions.
2. Detect changed packages. Check each release unit under packages/, sdks/, and the repo root for changes since its last release tag. Use path-scoped diffs for subpackages so unrelated repo changes do not trigger a package release, e.g. git diff kosong-0.53.0..HEAD -- packages/kosong, git diff pykaos-0.9.0..HEAD -- packages/kaos, and git diff kimi-sdk-0.2.1..HEAD -- sdks/kimi-sdk. If nothing changed anywhere, stop and report that there is nothing to release. Note: packages/kimi-code is a thin wrapper and must stay version-synced with kimi-cli, so treat it as changed whenever the root package changes.
3. Confirm new versions with the user. For each changed package, propose a new version and confirm before editing. Versioning policy:
   • Patch is always 0.
   • Bump the minor version for any change.
   • Major only changes by explicit manual decision from the user.
4. Create the release branch. Name it bump-<package>-<new-version>. If multiple packages are being bumped together, use a single branch with a descriptive name.
5. Update version metadata and changelogs. For each changed package:
   • Update its pyproject.toml.
   • Update CHANGELOG.md, keeping the ## Unreleased header empty in place (do not rename it — add a new dated ## <version> (YYYY-MM-DD) section below it).
   • Update breaking-changes.md in both languages if there are breaking changes.
   • If bumping packages/kosong or packages/kaos, also update the root pyproject.toml pinned dependency (kosong[contrib]==<version> or pykaos==<version>) so root validation keeps passing.
6. Sync the kimi-code wrapper when the root version changes. Bump packages/kimi-code/pyproject.toml version to match the new root version. It is a legacy stub with no dependencies — do not add a kimi-cli pin back.
7. Run uv sync to refresh the lockfile.
8. Update docs. Follow the gen-docs skill to make sure docs reflect the release.

9. Confirm with the user before opening the PR. Summarize the staged changes and ask the user to explicitly confirm:

   • Version numbers — every updated pyproject.toml (changed package + packages/kimi-code if the root moved) reflects the version agreed in step 3.
   • Dependency pins — the root pyproject.toml pins (kosong[contrib]==<version>, pykaos==<version>) match the bumped versions.
   • Documentation — CHANGELOG entries are added below ## Unreleased (Unreleased still present and empty), breaking-changes.md is updated in both languages if applicable, and gen-docs left no inconsistencies.

   Wait for explicit user approval before proceeding. If the user flags anything, fix it and re-confirm — do not push.

10. Open the PR. Commit all changes, push, and open a PR with gh. The PR description must follow this structure (see https://github.com/MoonshotAI/kimi-cli/pull/2225 for reference):

    ## Summary
    - Bump <package> to <version>
    - Move the current release notes under <version>
    - (If applicable) Move breaking-change entries under <version>
    - (If applicable) Any additional noteworthy changes (dependency pin updates, etc.)
    
    ## Validation
    - uv run python scripts/check_version_tag.py --pyproject <pyproject> --expected-version <version>
    - (For root releases) uv run python scripts/check_version_tag.py --pyproject packages/kimi-code/pyproject.toml --expected-version <version>
    - uv run python scripts/check_kimi_dependency_versions.py --root-pyproject pyproject.toml --kosong-pyproject packages/kosong/pyproject.toml --pykaos-pyproject packages/kaos/pyproject.toml
    - make check
    
    ## Post-merge
    After this PR lands, create and push the release tag:
    
    ```sh
    git tag <tag>
    git push origin <tag>

11. Hand off the tag step. After merge, switch to main, pull latest, and tell the user the exact git tag command for the final release tag (pick the right tag pattern from the table above — e.g. git tag 1.43.0 for a root release, git tag kosong-0.54.0 for a kosong release). The user will run the tag and push tags themselves.

Stop conditions

Fail fast — never paper over an error to keep the release moving. Stop and report back to the user when any of these happen:

• Nothing changed since the last tag → there is nothing to release.
• uv sync fails or produces unexpected uv.lock churn beyond the version bump.
• gen-docs reports a doc inconsistency you cannot resolve.
• PR checks go red after push — investigate, do not --no-verify or force-merge.
• The release workflow fails after tag push — read the workflow logs and surface the failure, do not retag silently.
