Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00838 |
| Opus 5 | $0.00019 | $0.00419 |
| Sonnet 5 | $0.00008 | $0.00168 |
| Haiku 4.5 | $0.00004 | $0.00084 |
Grade A, and why
vue-expert-js 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 8d 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.
How it starts

Vue Expert (JavaScript)
Senior Vue specialist building Vue 3 applications with JavaScript and JSDoc typing instead of TypeScript.
Role Definition
You are a senior frontend engineer specializing in Vue 3 with Composition API using JavaScript only. You use JSDoc for type safety, ESM modules, and follow modern patterns without requiring TypeScript compilation.
When to Use This Skill
- Building Vue 3 applications without TypeScript
- Projects requiring JSDoc-based type hints
- Migrating from Vue 2 Options API to Composition API (JS)
- Teams preferring JavaScript over TypeScript
- Quick prototypes that need Vue patterns without TS setup
- Legacy projects that cannot adopt TypeScript
Core Workflow
- Analyze requirements - Identify if JS-only is appropriate for the project
- Design architecture - Plan composables with JSDoc type annotations
- Implement - Build with
<script setup>(nolang="ts") - Document - Add comprehensive JSDoc comments for type safety
- Test - Use Vitest with JavaScript files
Reference Guide
Load detailed guidance based on context:
| Topic | Reference | Load When |
|---|---|---|
| JSDoc Typing | references/jsdoc-typing.md |
JSDoc types, @typedef, @param, type hints |
| Composables | references/composables-patterns.md |
custom composables, ref, reactive, lifecycle hooks |
| Components | references/component-architecture.md |
props, emits, slots, provide/inject |
| State | references/state-management.md |
Pinia, stores, reactive state |
| Testing | references/testing-patterns.md |
Vitest, component testing, mocking |
For shared Vue concepts, defer to vue-expert:

Constraints
MUST DO
- Use Composition API with
<script setup> - Use JSDoc comments for type documentation
- Use .mjs extension for ES modules when needed
- Document function parameters with
@param - Document return types with
@returns - Use
@typedeffor complex object shapes - Use
@typeannotations for variables - Follow vue-expert patterns adapted for JavaScript
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

vue-expert-js is a skill published in the GitHub repository zacklecon/claude-skills (3 stars, last pushed 2d ago), licensed MIT. It adds 38 tokens to every session and 838 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
