mcp-lab: Skill for Claude Code

.agents/skills/inertia-react-development/SKILL.md

inertia-react-development is a skill for Claude Code, Codex from jaksa-v/mcp-lab. It costs 86 tokens per session (3,117 once invoked), scanned C, original, no licence file.

A development guide for building React applications with Inertia.js v3. React is a JavaScript interface library, while Inertia connects React pages to a server-side application without requiring a separate API for every page.

In plain words
What is it for?
It is for creating React pages, forms, and navigation with Inertia, including deferred data, prefetching, optimistic updates, instant visits, and polling.
Why use it?
It provides guidance for the specific patterns used when React and Inertia work together. The description does not identify the server-side framework involved.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is jaksa-v/mcp-lab's own configuration. It tells Claude Code and Codex how to work on mcp-lab 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 mcp-lab 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 C, and why

inertia-react-development scanned grade C with 1 finding 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 2mo 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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.
