What it does
Fantasia Electron Preload is an agent skill from vishiri/fantasia-archive. Extends or fixes renderer-facing Electron APIs exposed through the preload script and contextBridge. Use when adding IPC-like surface area, typing window.faContentBridgeAPIs, editing src-electron/contentBridgeAPIs, or extending shared IPC channel names in electron-ipc-bridge.ts.
Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: A world-builder's best friend! The licence is GPL-3.0.
When your agent uses it
- Adding IPC-like surface area
- Typing window.faContentBridgeAPIs
- Editing src-electron/contentBridgeAPIs
- Extending shared IPC channel names in electron-ipc-bridge.ts
Example prompts
- “Use the fantasia-electron-preload skill to extend or fixes renderer-facing Electron APIs exposed through the preload script and contextBridge”
- “/fantasia-electron-preload”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Contract in types/I_.ts
- Channels in electron-ipc-bridge.ts + register*Ipc.ts + startup
- Implement contentBridgeAPIs/.ts
- Add to apiObject in electron-preload.ts
- Extend globals.d.ts
- Vitest: contentBridgeAPIs/_tests/, ipcManagement/_tests/ — dev scoped connected specs during edits; full yarn testbatch:verify enforces…
What it can do on your machine
Read from SKILL.md and the folder at commit 26d4648. 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:
yarn
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use yarn, 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
Fantasia Electron Preload loads about 693 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 193 words of instructions outside code blocks.
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.

Fantasia Archive — preload and content bridge
Architecture
- JSDoc/comments in
src-electron/: AGENTS.md comment rules — no Markdown emphasis; single quotes for refs - Preload:
electron-preload.ts→contextBridge.exposeInMainWorld('faContentBridgeAPIs', apiObject) - Renderer:
window.faContentBridgeAPIs—src/globals.d.ts - Implementations:
contentBridgeAPIs/*.tsper API (window control, keybinds, project management,projectContentAPI, …)
Main ↔ preload IPC (electron-ipc-bridge)
- Async first:
ipcRenderer.invoke+ipcMain.handle.sendSynclast resort only - Registry:
electron-ipc-bridge.ts—FA_*_IPCconstants; never duplicate string literals - Main:
register*Ipc.tswired fromstartApp() - Preload: import constants in
contentBridgeAPIs/*.ts
Adding a new API surface
- Contract in

Security and boundaries
- Narrow explicit methods — no raw Node/Electron objects to renderer
- No broad
nodeIntegrationin renderer - Sandboxed preload → IPC to main for
shell, paths, etc. - Privileged calls via
invoke— no@electron/remotewithout documented reason - No
neverthrowin preload —Promisechains; see neverthrow.mdc - Structured IPC args validated in main with Zod — fantasia-electron-main
faDevToolsControl: packaged installs must still toggle DevTools — product law, not optional hardening. fantasia-electron-main Packaged DevTools; rule electron-preload.mdc
