What it does

Sync Site App is an agent skill from FontWoW/FontWoW.github.io. Enforces that any new/changed user-facing capability is added to BOTH the marketing site (Landing.jsx / src/features.js) AND the real app (App.jsx and friends) — never just one. Trigger on "قابلیت جدید اضافه کن", "این امکان رو اضافه کن به اپ/سایت", "فیچر جدید", "option/feature/امکان جدید", or any request to add, change, or remove an editor capability, export option, style/effect, template, or anything listed in the "امکانات" section on the landing page.

Its SKILL.md is about 730 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 Frontend & Design, covering Landing pages and React components. The licence is GPL-3.0.

When your agent uses it

  • قابلیت جدید اضافه کن
  • این امکان رو اضافه کن به اپ/سایت
  • Option/feature/امکان جدید
  • Any request to add

Example prompts

  • “option/feature/امکان جدید”
  • “Use the sync-site-app skill to enforce that any new/changed user-facing capability is added to BOTH the marketing site (Landing.jsx /…”
  • “/sync-site-app”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Implement it for real in the app — the actual editor behavior in src/App.jsx (or
  2. Reflect it in src/features.js — add/update/remove the matching entry so the landing page
  3. Do both in the same change. Never ship an app capability without updating the site's

What it can do on your machine

Read from SKILL.md and the folder at commit 1b58eb6. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Sync Site App loads about 731 tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 342 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~118
When it runs · the whole SKILL.md, loaded when a task matches
~731

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.

description
Enforces that any new/changed user-facing capability is added to BOTH the marketing site (Landing.jsx / src/features.js) AND the real app (App.jsx and friends) — never just one. Trigger on "قابلیت جدید اضافه کن", "این امکان رو اضافه کن به اپ/سایت", "فیچر جدید", "option/feature/امکان جدید", or any request to add, change, or remove an editor capability, export option, style/effect, template, or anything listed in the "امکانات" section on the landing page.

Sync site ↔ app

FontWoW ships two surfaces from one repo:

  • سایت (site) — src/Landing.jsx, the marketing/landing page. Its "امکانات" section renders from src/features.js.
  • اپلیکیشن (app) — src/App.jsx (plus src/native.js, src/templates.json, etc.), the real editor where the capability actually lives.

src/features.js is the canonical registry connecting the two. It is mandatory, not optional, that these move together.

Rule

Whenever a user-facing option/capability is added, changed, or removed:

  1. Implement it for real in the app — the actual editor behavior in src/App.jsx (or src/native.js, src/templates.json, etc. as appropriate).
  2. Reflect it in src/features.js — add/update/remove the matching entry so the landing page description stays accurate. Use an existing card if the new capability is a variant of one already listed (e.g. a new text effect belongs under "استایل و افکت متن"); only add a new card for a genuinely new capability category.
  3. Do both in the same change. Never ship an app capability without updating the site's description of it, and never edit src/features.js to describe something that isn't actually implemented in the app yet.

Treat this as a hard gate before considering the task done — if you changed one side and not the other, the task is incomplete.

Workflow

  1. Read src/features.js to see current entries and decide whether the change fits an existing card or needs a new one.
  2. Make the real implementation change in src/App.jsx (or wherever the capability actually lives).
  3. Update src/features.js to match (iconName must reference a real export from src/icons.jsx — check with grep "^export" src/icons.jsx if unsure which icons exist).
  4. Landing.jsx imports FEATURES from src/features.js and needs no further edits unless the overall section layout/copy around it changes.
  5. If the change is significant enough to warrant new screenshots (docs/screen-*.png referenced in Landing.jsx), flag that to the user rather than silently skipping it — don't generate fake screenshots.
  6. Before finishing, diff-check: does every new/changed capability in this change have a corresponding entry in src/features.js, and does every src/features.js entry you touched correspond to something real in the app? If not, go back and fix the missing side.
