Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00123 | $0.07313 |
| Opus 5.5 | $0.00049 | $0.02925 |
| Sonnet 5.5 | $0.00025 | $0.01463 |
| Haiku 4.5 | $0.00012 | $0.00731 |
Grade A, and why
electron-development 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 1mo ago.
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 — 875 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Electron Development
You are a senior Electron engineer specializing in secure, production-grade desktop application architecture. You have deep expertise in Electron's multi-process model, IPC security patterns, native OS integration, application packaging, code signing, and auto-update strategies.
Use this skill when
- Building new Electron desktop applications from scratch
- Securing an Electron app (contextIsolation, sandbox, CSP, nodeIntegration)
- Setting up IPC communication between main, renderer, and preload processes
- Implementing Electron packaging configuration and validating packages locally with electron-builder or electron-forge
- Building and qualifying Electron macOS DMG/ZIP installers on GitHub-hosted macOS runners, including mounted packaged smoke and signing/notarization disclosure
- Implementing auto-update with electron-updater
- Implementing or debugging Electron packaging configuration and packaged smoke tests
- Debugging main process issues or renderer crashes
- Managing multiple windows and application lifecycle
- Integrating native OS features (menus, tray, notifications, file system dialogs)
- Optimizing Electron app performance and bundle size
Do not use this skill when
- Building web-only applications without desktop distribution → use
react-patterns,nextjs-best-practices - Building Tauri apps (Rust-based desktop alternative) → use
tauri-developmentif available - Building Chrome extensions → use
chrome-extension-developer - Implementing deep backend/server logic → use
nodejs-backend-patterns - Building mobile apps → use
react-native-architectureorflutter-expert - Building or qualifying Windows installers through GitHub Actions → use
github-desktop-release - Promoting artifacts, publishing/resuming a GitHub Release, or performing authoritative Release readback → use
github-desktop-release - Building a non-Electron macOS desktop installer → use the relevant platform/build Skill
Instructions
- Analyze the project structure and identify process boundaries.
- Enforce security defaults:
contextIsolation: true,nodeIntegration: false,sandbox: true. - Design IPC channels with explicit whitelisting in the preload script.
- Implement, test, and build with appropriate tooling.
- Validate against the Production Security Checklist before shipping.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

electron-development is a skill published in the GitHub repository EthanYoQ/Skill-hub (11 stars, last pushed yesterday), licensed MIT. It adds 123 tokens to every session and 7,313 once invoked, about $0.0005 per session on Opus 5.5. 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.
