claude-react-kit: Skill for Claude Code

.claude/skills/setup/SKILL.md

setup is a skill for Claude Code from aleolidev/claude-react-kit. It costs 22 tokens per session (1,654 once invoked), scanned A, original, MIT.

A project setup skill that examines an existing codebase and installs claude-react-kit according to its framework, files, and coding conventions.

In plain words
What is it for?
Use it to inspect dependencies, lock files, TypeScript and framework settings, linting, existing instructions, and source folders before generating configuration.
Why use it?
It avoids applying a generic setup that conflicts with the project's existing tools or structure.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is aleolidev/claude-react-kit's own configuration. It tells Claude Code how to work on claude-react-kit 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 claude-react-kit 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

setup 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 1mo 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.

claude-react-kit — Setup

You are setting up claude-react-kit in this project. Your job is to analyze the codebase, understand its real stack and conventions, and generate perfectly customized configuration files.

Phase 1: Deep Analysis

Analyze the project thoroughly. Read and extract information from:

  1. package.json — framework, dependencies, scripts, package manager (check for packageManager field too)
  2. Lock file — which exists? (package-lock.json, yarn.lock, pnpm-lock.yaml, bun.lock, bun.lockb)
  3. tsconfig.json — path aliases, strict mode, baseUrl, target
  4. Framework config — next.config.*, vite.config.*, app.json/app.config.* (Expo), metro.config.*, remix.config.*
  5. Linter/formatter — .eslintrc*, eslint.config.*, .prettierrc*, biome.json
  6. Existing CLAUDE.md — if one exists, read it to preserve any project-specific rules the user already has
  7. Existing .claude/ — if it exists, read settings.json and any custom rules to preserve them
  8. Source directory structure — ls src/ or equivalent to understand the current architecture (do they already have features/, shared/, core/, design-system/, or different names?)
  9. Routing — ls app/ or ls pages/ or ls src/screens/ to understand routing structure
  10. State management patterns — grep for store/slice/atom definitions to understand actual usage
  11. Test setup — jest.config.*, vitest.config.*, test file patterns
  12. CI/CD — .github/workflows/, check what checks run

Build a complete mental model of the project before writing anything.

Phase 2: Ask What You Can't Detect

After analysis, present your findings to the user in a concise summary:

Here's what I detected:
- Framework: [X]
- Package manager: [X]
- Source structure: [describe what you found]
- State management: [X]
- Testing: [X]
- Styling: [X]
- Existing CLAUDE.md: [yes/no, summary if yes]
- Path aliases: [X]

Then ask ONLY about things you genuinely couldn't determine:

  • If the architecture doesn't clearly match the 5-layer model, ask how they want to map their directories
  • If there are conventions you noticed but aren't sure if they're intentional
  • If there's an existing CLAUDE.md, ask what to keep vs replace
  • Any ambiguities in their setup

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.

setup is a skill published in the GitHub repository aleolidev/claude-react-kit (2 stars, last pushed 8mo ago), licensed MIT. It adds 22 tokens to every session and 1,654 once invoked, about $0.0001 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 2026-08-31.
