What it does

Create Rc Tag is an agent skill from NVIDIA/NeMo-Relay, published by the product's own GitHub organization. Create and push a signed, annotated NeMo Relay release-candidate tag from its validated release branch. Use when cutting an RC tag; not for code freezes or stable tags.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with NVIDIA AI Platform. The repository describes itself as: Multi-language agent runtime and library for execution scope management, lifecycle events, and middleware on tool and LLM calls. The licence is Apache-2.0.

When your agent uses it

Cutting an RC tag
Not for code freezes

Example prompts

“/create-rc-tag”

What it can do on your machine

Read from SKILL.md and the folder at commit 16d73b4. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Create Rc Tag loads about 635 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~46
When it runs · the whole SKILL.md, loaded when a task matches: ~635

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Create and push a signed, annotated NeMo Relay release-candidate tag from its validated release branch. Use when cutting an RC tag; not for code freezes or stable tags.
license: Apache-2.0

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.

bash

BASE_VERSION=<major.minor[.patch]>
[[ "$BASE_VERSION" =~ ^[0-9]+\.[0-9]+(\.[0-9]+)?$ ]] || { echo "Error: invalid base version" >&2; exit 1; }
if [[ "$BASE_VERSION" =~ ^[0-9]+\.[0-9]+$ ]]; then BASE_VERSION="$BASE_VERSION.0"; fi
RELEASE_BRANCH="release/$(printf '%s' "$BASE_VERSION" | cut -d. -f1,2)"
git ls-remote --exit-code --heads upstream "refs/heads/$RELEASE_BRANCH"
git fetch upstream "$RELEASE_BRANCH" --tags

LAST_RC="$(git tag --list "${BASE_VERSION}-rc.*" | sed -nE "s/^${BASE_VERSION//./\\.}-rc\.([1-9][0-9]*)$/\\1/p" | sort -n | tail -1)"
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:

bash

git tag -s -a -m "NVIDIA NeMo Relay ${TAG}" "$TAG" HEAD
git tag -v "$TAG"
git push upstream "refs/tags/$TAG"
