What it does

Fantasia Dev Setup is an agent skill from vishiri/fantasia-archive. Sets up and runs Fantasia Archive locally using Yarn, Node.js 22.22 or newer, and Quasar Electron mode. Use when installing dependencies, choosing dev vs production build commands, or when the user mentions environment setup, CLI, or first run.

Its SKILL.md is about 930 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 Testing & QA. It works with Node.js and Playwright. The repository describes itself as: A world-builder's best friend! The licence is GPL-3.0.

When your agent uses it

  • Installing dependencies
  • Choosing dev vs production build commands
  • The user mentions environment setup

Example prompts

  • “/fantasia-dev-setup”

Requirements

  • Node.js

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 Dev Setup loads about 933 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 256 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~933

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 — dev setup

Toolchain

  • Package manager: Yarn 1.x (CI: yarn@1.22.19)
  • Node.js: 22.22.0+ (package.json engines.node >=22.22.0)
  • Quasar CLI (optional global): yarn global add @quasar/cli
  • CI: .github/workflows/verify.yml — yarn testbatch:verify only; Storybook VRT local only

Install

bash
yarn

DnD libs (vue-draggable-plus, quasar-ui-q-draggable-table) in package.json; boot q-draggable-table. Policy: fantasia-drag-drop.

Run (development)

bash
quasar dev -m electron

(yarn quasar:dev:electron). Electron + Storybook together: yarn app:dev.

Post-implementation agent gates (dev-electron-compile-check.mdc): (1) dev scoped gate (fantasia-dev-scoped-verify), (2) yarn quasar:dev:electron 20s compile smoke — separate terminals; kill agent-spawned dev after pass. Full yarn testbatch:verify only at final cleanup, commit, or explicit user request.

Troubleshooting

Electron failed to install correctly

Postinstall skipped → missing node_modules/electron/dist.

bash
rm -rf node_modules/electron   # PowerShell: Remove-Item -Recurse -Force node_modules/electron
yarn install
# or: node node_modules/electron/install.js
DevTools Autofill CDP noise

Harmless stderr; main process filters specific lines.

better-sqlite3 bindings missing

Native addon must match Electron ABI.

bash
yarn rebuild:native

Close quasar dev first on Windows file locks. If still fails: remove node_modules/better-sqlite3, yarn install (scripts enabled), yarn rebuild:native again.

Production build

Required for packaged behavior + before Playwright:

bash
quasar build -m electron

(yarn quasar:build:electron = quasar build -m electron --publish never).

Quieter: yarn quasar:build:electron:summarized — log in test-results/quasar-build-electron-last.log.

Playwright userData: TEST_ENV components/e2e → %APPDATA%/fantasia-archive/playwright-user-data. Serial suites reset in test.beforeAll only — see fantasia-testing.
