A release-readiness workflow for Expo mobile apps that checks build settings, store requirements, deployment credentials, and code quality. Expo is a toolkit for developing and publishing React Native apps.

It is for validating EAS build profiles, iOS and Android identifiers, certificates, permissions, privacy descriptions, signing keys, Firebase files, and update settings.

It helps uncover configuration, signing, privacy, versioning, and store-submission problems before a build or release is submitted.

Token cost

What it costs to keep this loaded

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	$0.00023	$0.00577
Opus 5	$0.00012	$0.00289
Sonnet 5	$0.00005	$0.00115
Haiku 4.5	$0.00002	$0.00058

Security

Grade A, and why

erne-deploy 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 10d ago.

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.

Origin

This is a copy

86% identical to deploy — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/erne-deploy — Validate & Submit

You are executing the /erne-deploy command. Run expo-config-resolver and code-reviewer in parallel. One validates build/deploy config, the other reviews code quality.

Parallel Execution

Agent 1: expo-config-resolver — Build & Deploy Validation

Check all deployment prerequisites:

EAS Configuration:

eas.json profiles are correct for target channel (preview/production)
app.config.ts version and build numbers are bumped
Runtime version policy is set correctly for OTA updates
Environment variables and secrets are configured in EAS

Platform-Specific Checks:

iOS:

Bundle identifier matches Apple Developer account
Provisioning profiles are valid (not expired)
Capabilities (push, sign-in, etc.) match entitlements
Privacy descriptions (NSCameraUsageDescription, etc.) are present
App Store Connect metadata is ready

Android:

Package name matches Play Console listing
Signing key is configured in EAS credentials
google-services.json is current (if using Firebase)
Target SDK meets Play Store requirements
Content rating questionnaire is completed

OTA Update Validation:

Check if OTA update is sufficient vs new native build needed
Verify runtime version compatibility
Test update on preview channel first

Agent 2: code-reviewer — Pre-Submit Code Review

Focus on production readiness:

No console.log statements
No debug flags (__DEV__ guards are correct)
Error boundaries are in place
Crash reporting is configured
Analytics events are correct
No hardcoded API URLs (use environment config)
Feature flags for staged rollout

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.
