What it does

Regle Rules is an agent skill from victorgarciaesgi/regle. Regle validation rules — built-in rules from @regle/rules, custom rules with createRule, rule wrappers (withMessage, withParams, withAsync, withTooltip), and rule operators (and, or, xor, not, applyIf, assignIf, pipe). Use when declaring, customizing, composing, or conditionally applying validation rules in a Regle form. For form setup see regle.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/rules-built-in.md`, `references/rules-custom.md` and `references/rules-operators.md`). Compatibility notes: Requires Vue 3.3+ and TypeScript 5.1+. Works with any agent supporting the Agent Skills spec.

It works with Vue.js. The repository describes itself as: ✅ Headless form validation library for Vue.js. The licence is MIT.

When your agent uses it

Conditionally applying validation rules in a Regle form

Example prompts

“/regle-rules”

Requirements

Compatibility (from SKILL.md): Requires Vue 3.3+ and TypeScript 5.1+. Works with any agent supporting the Agent Skills spec.

What it can do on your machine

Read from SKILL.md and the folder at commit 9d69771. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires Vue 3.3+ and TypeScript 5.1+. Works with any agent supporting the Agent Skills spec.
From compatibility in the SKILL.md frontmatter.

Context cost

Regle Rules loads about 564 tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 147 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~97
When it runs · the whole SKILL.md, loaded when a task matches: ~564
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~3.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Regle Rules

Validation rules for Regle. Rules come from @regle/rules, but you can also write your own with createRule, customize them with wrappers, and combine them with operators.

import { useRegle } from '@regle/core';
import { required, email, minLength } from '@regle/rules';

const { r$ } = useRegle(
  { email: '' },
  { email: { required, email, minLength: minLength(5) } }
);

Key Concepts

All rules are optional by default; add required to enforce a field.
Built-in rules are imported from @regle/rules; some are factories that take parameters (e.g. minLength(3)).
Custom rules use createRule for reusability, or an inline function for one-offs.
Wrappers adapt an existing rule (message, params, async, tooltip) without rewriting it.
Operators combine or conditionally apply rules.
