react-hook-form

react-hook-form is a skill for Claude Code from Fandhe-AI/agent-reference-skills. It costs 106 tokens per session (1,057 once invoked), scanned A, original, no licence file.

A reference for React Hook Form, a React library for collecting and validating form data. It covers form registration, submission, watched values, dynamic field lists, controlled components, errors, and validation with common schema libraries.

In plain words
What is it for?
Use it to create React forms, validate input, show errors, connect custom controls, manage repeatable fields, and reset or read form values.
Why use it?
It helps an agent build forms with the library's intended hooks and data flow. This reduces repetitive state handling and mistakes in validation, error display, and dynamic fields.

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 9d 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.
