Prepare SkiaSharp release branches with the repository-owned PowerShell script.

  • A maintainer asks to start
  • Calls gh
  • Cut a stable release branch

What it does

Release Branch is an agent skill from mono/SkiaSharp. Prepare SkiaSharp release branches with the repository-owned PowerShell script. Use when a maintainer asks to start, prepare, preview, RC, or cut a stable release branch.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Shell scripting. It works with PowerShell. The repository describes itself as: SkiaSharp is a cross-platform 2D graphics API for .NET platforms based on Google's Skia Graphics Library. It provides a comprehensive 2D API that can be used across mobile… The licence is MIT.

When your agent uses it

  • A maintainer asks to start
  • Cut a stable release branch

Example prompts

  • “/release-branch”

What it can do on your machine

Read from SKILL.md and the folder at commit cb51ed5. 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:

    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh, 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

Release Branch loads about 670 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 226 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
~670

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.

Prepare SkiaSharp release branches with the repository-owned PowerShell script. Use when a maintainer asks to start, prepare, preview, RC, or cut a stable release branch.

Release Branch

Use the Release - Prepare GitHub workflow for normal releases. In chat, dispatch it on main with push=false first, inspect the read-only plan, and obtain confirmation before dispatching the same inputs with push=true:

bash
gh workflow run release-prepare.yml --repo mono/SkiaSharp --ref main \
  -f base=main -f release=4.153.0-preview.1 -f push=false

# After reviewing the plan and receiving confirmation:
gh workflow run release-prepare.yml --repo mono/SkiaSharp --ref main \
  -f base=main -f release=4.153.0-preview.1 -f push=true

Replace the example base and identity with the requested values. Locate and inspect each dispatched run; never infer success from a successful dispatch. Verify both release branches exist at the planned commits before proceeding. The branch push starts the internal skiasharp-package and skiasharp-tests chain. Package publication is a separate, explicitly requested release-publish action; Prepare must not queue it.

The Prepare workflow accepts:

  • base: a SkiaSharp branch or commit SHA;
  • release: X.Y.Z[-preview.N|-rc.N|-stable], or the corresponding four-part hotfix form X.Y.Z.F[-preview.N|-rc.N|-stable].

Local fallback

Use the local script only when the workflow is unavailable or the user explicitly requests local execution. It does not replace workflow verification:

powershell
# Read-only
./scripts/infra/publishing/prepare-release.ps1 -Base main -Release 4.153.0-preview.1 -Mode DryRun

# Create and validate local branches and commits
./scripts/infra/publishing/prepare-release.ps1 -Base main -Release 4.153.0-preview.1 -Mode Apply

# Create locally, push mono/skia then mono/SkiaSharp, and create a stable bump PR
./scripts/infra/publishing/prepare-release.ps1 -Base main -Release 4.153.0-preview.1 -Mode Push

Before -Mode Push, show the resolved base SHA and every planned ref to the user and obtain confirmation. Never force-update a release branch. Existing matching state is reused; conflicting state blocks the run.

Stable input deliberately uses the explicit -stable sentinel to prevent an accidental stable cut, but creates the bare release/X.Y.Z branch. A three-part stable release also prepares the next SkiaSharp patch and HarfBuzzSharp revision on bump-version-X.Y.Z. Its PR targets a manually created release/X.Y.x servicing line when one exists, otherwise main; release preparation never creates the .x line.
