Slang Release

Slang Release

For: the write-heavy release-engineering tasks that move released Slang into the internal GitLab forks. This is the counterpart to the read-only slang-maintainer-tools skill (which covers daily reports, release-notes drafting, issue prioritization, and review messages).

Usage:

/slang-release [task]

  task  update-spirv   Update SPIRV-Tools + SPIRV-Headers submodules and regenerate files
        update-gitlab  Integrate GitHub release into the GitLab nv-* forks (3-repo OptiX triad)
        full-release   Run the release sequence end to end (report → notes → spirv → gitlab)

If no task is given, ask which one to run.

Task → recipe

Cross-cutting pitfalls (branch-protection asymmetry, pre-existing OV failures, GitLab pipeline checking, remote-naming, release-pinned rebase base): gotchas.md.

Safety contract (applies to every task)

• Never force-push without explicit user confirmation. Force-pushes here overwrite shared integration branches (nv-master, nv-internal, nv-main) that the whole team builds from.
• Always create a before-rebase-* backup branch and push it before any history rewrite, so the prior state is recoverable.
• Validate before overwriting. The OptiX ray-query path can only be verified on a machine with an NVIDIA GPU + CUDA + OptiX SDK. Do the rebase groundwork anywhere, but gate the force-push on a real GPU validation (see gotchas.md).
• Check git status is clean before major operations.

WSL tool handling

This skill runs git, cmake, python3, curl, and gh. Detect WSL and select tools accordingly:

IS_WSL=0
if grep -qiE "(microsoft|wsl)" /proc/version 2>/dev/null; then IS_WSL=1; fi

if [ "$IS_WSL" = "1" ]; then
  GIT=git.exe; CMAKE=cmake.exe; PYTHON=python.exe; GH=gh.exe
else
  GIT=git; CMAKE=cmake; PYTHON=python3; GH=gh
fi

Under WSL, prefer the Windows-native .exe tools (git.exe, cmake.exe, python.exe, gh.exe) for anything that touches a Windows-created worktree, builds with Visual Studio presets, or relies on GitHub auth state — their WSL and Windows versions are materially different (a Windows worktree can be incompatible with WSL git; WSL cmake does not recognize the VS presets). If a required Windows-native tool is missing, stop and report it rather than silently falling back to the WSL-native tool. Use WSL-native tools only when the user explicitly asks for a native WSL run.

Reference documents (read fresh — layouts drift)

• SPIRV update process (GitHub): docs/update_spirv.md in the slang repo.
• GitLab integration process: lives on the GitLab nv-master branch at gitlab-only/docs/update_gitlab.md — read it first: git show gitlab/nv-master:gitlab-only/docs/update_gitlab.md. All GitLab-unique files live under the gitlab-only/ directory.
• Release notes: docs/scripts/release-note.sh in the slang repo, or the MCP-based recipe in slang-maintainer-tools/release-notes.md.
