Expo Examples

What it does

When your agent uses it

• Integrating a third-party library
• Service into an existing Expo app and you want the canonical
• Version-matched pattern to adapt
• Scaffolding a new project from one with npx create-expo --example

Example prompts

• “/expo-examples”

Requirements

• Node.js
• Pre-approved tools (allowed-tools): Read, Bash(gh api:*), Bash(git clone:*), Bash(npx create-expo:*), Bash(npx degit:*), Bash(bun create:*)

Workflow steps

2 steps, taken from the step headings in SKILL.md.

1. 1Find the right example
2. 2Adapt into the user's app — non-destructively (critical)

What it can do on your machine

Read from SKILL.md and the folder at commit d4f4840. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Bash(gh api:*)
  • Bash(git clone:*)
  • Bash(npx create-expo:*)
  • Bash(npx degit:*)
  • Bash(bun create:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • gh
  • npx
  • git
  • curl
  • bun

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • github.com
  • launch.expo.dev
  • raw.githubusercontent.com

  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

Expo Examples loads about 1.7k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 102 tokens; SKILL.md has 669 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~102

When it runs · the whole SKILL.md, loaded when a task matches

~1.7k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.8k

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

• NoteMentions a .env fileSKILL.md:46

  ntegration code the manifest revealed → `.env` (required secrets). Per file:

• NoteMentions a .env fileSKILL.md:79

  *Recreate env vars** from the example's `.env` shape — it holds placeholders, never working secrets.

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

Expo's official example projects - the expo/examples repo of ~70 `with-*` integrations (Stripe, Clerk, Supabase, OpenAI, maps, Reanimated, SQLite, Skia, NativeWind, and more). Use when integrating a third-party library or service into an existing Expo app and you want the canonical, version-matched pattern to adapt, or when scaffolding a new project from one with `npx create-expo --example`.

allowed-tools

Read, Bash(gh api:*), Bash(git clone:*), Bash(npx create-expo:*), Bash(npx degit:*), Bash(bun create:*)
