NeMo-Relay: Skill for Claude Code

Create an RC Tag

Require an explicit stable base version in <major>.<minor>[.<patch>] form; treat two components as patch 0. Do not infer it from the branch or package metadata, and do not edit version files while creating the tag. The matching release/<major>.<minor> branch must exist on upstream.

Select the next unused positive RC number for that exact base version unless the user supplies one. Relay uses raw-SemVer tags such as 0.9.0-rc.1, without a leading v.

Before the destructive tag push, require explicit approval. Preserve user changes: do not stash, discard, or switch away from a dirty checkout. Fetch the release branch and tags, require HEAD to equal the upstream release branch, and require the workspace version to equal the stable base version. Verify that both local and remote tags are absent, create a signed annotated tag, verify it with git tag -v, and push only refs/tags/<tag>. Stop on any failed check; never force-update, replace, or delete tags.

Select and Verify the Source

Use upstream for NVIDIA/NeMo-Relay. The version and optional RC number are user inputs. Validate a supplied number as a positive integer; otherwise derive the next number after fetching the release branch and tags.

RC_NUMBER="${RC_NUMBER:-$(( ${LAST_RC:-0} + 1 ))}"
[[ "$RC_NUMBER" =~ ^[1-9][0-9]*$ ]]
TAG="${BASE_VERSION}-rc.${RC_NUMBER}"

From a clean checkout of RELEASE_BRANCH, require HEAD to match upstream/$RELEASE_BRANCH, verify the workspace version matches BASE_VERSION, and check that TAG is absent locally and on upstream. After the user authorizes the push:
