inertia-react-development

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

A set of development guidance for React applications that use Inertia.js v3, a tool for building single-page interfaces with server-side web frameworks. It covers React pages, forms, navigation, and several Inertia features.

In plain words
What is it for?
It is for building pages and forms, navigating between views, using forms and routing helpers, and working with deferred data, prefetching, optimistic updates, instant visits, and polling.
Why use it?
It helps handle the client-side parts of an Inertia application consistently instead of treating them like a standalone React app.

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 6d 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.
