Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00050 | $0.00487 |
| Opus 5.5 | $0.00020 | $0.00195 |
| Sonnet 5.5 | $0.00010 | $0.00097 |
| Haiku 4.5 | $0.00005 | $0.00049 |
Grade A, and why
init-project 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 today.
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 — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Init Project
Turn this boilerplate into a new app's repository. Follow the actions in order. Each one needs the previous one done.
Actions
| Step | Action | Read |
|---|---|---|
| 1 | Propose the setup plan | Plan |
| 2 | Rename the app and remove samples | rename.md |
| 3 | Link EAS, set env files, run checks | services.md |
Resume from the first unfinished step. State the current step when stopping.
Plan
Change nothing in this step. Show one plan with these items:
| Item | Contains |
|---|---|
| Names | App name, package.json name, slug, URL scheme |
| IDs | iOS bundle IDs and Android packages for dev, stg, and prod |
| Expo account | owner in app.json, and whether to create new EAS projects or reuse ones |
| Samples | Files to remove or keep: __DELELE_ME__/, README banner, welcome sheet |
| Open | Anything the user has not decided |
Propose IDs in reverse-domain form, such as com.<company>.<app>, com.<company>.<app>.stg, and com.<company>.<app>.dev.
End the turn after the plan. Resolve Open items one at a time.
Rules
- Stop after the plan until the user approves it. Apply only approved items.
- Never enter passwords, API keys, or tokens. Ask the user to log in or set secrets.
- Write variable names to
.env.*.example. Never write secret values to git. - Ask one question at a time.
- Do not commit or push unless requested.
Report
- The result in the first sentence.
- Each created EAS project with its URL.
- Checks run and their results. Mark skipped checks.
- One next action at the end.
What ships with it
2 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.

init-project is a skill published in the GitHub repository wataru-maeda/react-native-boilerplate (519 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 487 once invoked, about $0.0002 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 2026-10-19.
