everything-react-native-expo: Skill for Claude Code

.claude/skills/plan/SKILL.md

plan is a skill for Claude Code from JubaKitiashvili/everything-react-native-expo. It costs 9 tokens per session (332 once invoked), scanned A, a copy of erne-plan, MIT.

A feature-planning command that designs the technical structure of a software feature before implementation.

In plain words
What is it for?
Use it to plan app components, Expo Router routes, state management, API calls, caching, and deep links, then review the plan before coding.
Why use it?
It turns a requirement into an organized plan covering files, screens, data, navigation, and implementation tasks.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is JubaKitiashvili/everything-react-native-expo's own configuration. It tells Claude Code how to work on everything-react-native-expo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything everything-react-native-expo configures →

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.

Security

Grade A, and why

plan 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

What it actually says

/plan — Feature Architecture Design

You are executing the /plan command. Use the architect agent to design a feature architecture.

Process

  1. Understand the requirement — Ask clarifying questions if the feature description is vague
  2. Analyze existing codebase — Read relevant files, understand current navigation structure, state management, and API patterns
  3. Design the architecture — Using the architect agent's process:
    • Decompose into components and screens
    • Plan Expo Router file structure
    • Select state management approach (Zustand / TanStack Query / local)
    • Design data flow and API layer
    • Consider platform-specific requirements
  4. Output the plan — Use the architect agent's output format:

Architecture Output

## Overview
[1-2 sentence description of the feature]

## File Structure
[New files to create with paths]

## Component Design
[Component hierarchy and responsibilities]

## Data Flow
[State management approach, API calls, caching strategy]

## Navigation
[New routes, layout changes, deep link support]

## Implementation Tasks
[Ordered list of implementation steps]
  1. Review with user — Present the plan and ask for approval before implementation

Notes

  • Reference the active platform rules layer (rules/expo/patterns.md or rules/bare-rn/patterns.md) for conventions
  • Consider whether this is Expo managed, bare RN, or has native modules
  • Include test strategy in the plan

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.
