github-desktop-release

A release workflow for Windows and macOS desktop installers built in GitHub Actions, GitHub’s cloud-based automation service. It checks that installers match one fixed source-code version before publishing them.

In plain words
What is it for?
Use it to check Windows installers, verify macOS release files, handle cloud packaging failures, and publish verified files in a GitHub Release.
Why use it?
It separates building, platform testing, file identity, and public release status, so a failed or mismatched installer is less likely to be published.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

github-desktop-release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/classify-actions-failure.mjs, scripts/github-desktop-promotion.mjs, scripts/preflight-windows-release.ps1, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Desktop Release

Treat a desktop release as a state machine, not a build command. Keep application implementation, platform qualification, artifact identity, and public GitHub Release state as separate evidence boundaries.

electron-development owns Electron macOS build and qualification. This Skill may validate a macOS qualification artifact before promotion, but does not take over that platform's build work.

Pick the smallest justified cloud path

Classify the request before spending runner time. Do not turn a past infrastructure failure into a permanent requirement for every release.

  • Compatibility preflight: a read-only or non-promotable check that proves each requested platform can receive the frozen source: runner label availability, locked-install viability, expected architecture/native binding load, and resolved asset plan. It produces no installer and cannot justify publication.
  • Standard Windows qualification: the default for ordinary application-source releases when the Windows installer, upgrade path, Electron/Node ABI, signing policy, and installer configuration are unchanged. It builds one installer and proves core installability.
  • Deep Windows acceptance: adds upgrade-data, native-ABI, and project-specific migration/installer checks. Use it only when its trigger is present or the user explicitly requests it.
  • Promotion/readback: consumes already-qualified bytes. It never builds, installs, or substitutes an artifact.

For a multi-platform release, choose between a staged canary and a parallel formal matrix from the release-risk delta. Ask electron-development to own macOS preflight and qualification work. A staged canary protects expensive minutes when release infrastructure changed; a parallel matrix protects elapsed time when that infrastructure is already proven.

Establish scope

  1. Read the repository's AGENTS.md, domain docs, packaging configuration, workflows, release scripts, and tests. Use CodeGraph first when the project is indexed.
  2. Record the repository, default branch, full source SHA, tag, version, requested platforms/architectures, signing policy, expected assets, and authorization boundary.
  3. Keep project facts in a repository release profile, not in this Skill. Read references/release-profile.md, then validate the selected profile:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

github-desktop-release is a skill published in the GitHub repository EthanYoQ/Skill-hub (9 stars, last pushed 4d ago), licensed MIT. It adds 48 tokens to every session and 3,008 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
