.agents/skills/react-hook-form/SKILL.md

react-hook-form is a skill for Claude Code, Codex from web3insight-ai/web3insight. It costs 85 tokens per session (1,549 once invoked), scanned A, original, no licence file.

A guide to building and optimizing client-side forms with the React Hook Form library, including validation and dynamic fields.

In plain words
What is it for?
Use it when creating controlled React forms with validation, watched fields, reusable controls, or repeatable field groups. It does not cover React 19 Server Actions.
Why use it?
It helps keep form code responsive and organized as forms become more complex. It also clarifies which React Hook Form APIs to use for common tasks.

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 web3insight-ai/web3insight's own configuration. It tells Claude Code and Codex how to work on web3insight 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 web3insight 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

react-hook-form 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.

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.
