jezweb/claude-skills is a collection of skills, commands, plugins, settings, instructions, and hooks that guide the Claude Code CLI through development tasks and produce outputs such as project scaffolds, assets, documents, or deployed services. It is for developers using Claude Code with technologies and services including Cloudflare, React, Tailwind, Shopify, and WordPress. The catalogue entries are the project's own Claude Code workflow components.
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.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00089 | $0.04646 |
| Opus 5.5 | $0.00036 | $0.01858 |
| Sonnet 5.5 | $0.00018 | $0.00929 |
| Haiku 4.5 | $0.00009 | $0.00465 |
Grade A, and why
google-apps-script scanned grade A 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Google Apps Script
Build automation scripts for Google Sheets and Workspace apps. Scripts run server-side on Google's infrastructure with a generous free tier.
What You Produce
- Apps Script code pasted into Extensions > Apps Script
- Custom menus, dialogs, sidebars
- Automated triggers (on edit, time-driven, form submit)
- Email notifications, PDF exports, API integrations
Workflow
Step 1: Understand the Automation
Ask what the user wants automated. Common scenarios:
- Custom menu with actions (report generation, data processing)
- Auto-triggered behaviour (on edit, on form submit, scheduled)
- Sidebar app for data entry
- Email notifications from sheet data
- PDF export and distribution
Step 2: Generate the Script
Follow the structure template below. Every script needs a header comment, configuration constants at top, and onOpen() for menu setup.
Step 3: Provide Installation Instructions
All scripts install the same way:
- Open the Google Sheet
- Extensions > Apps Script
- Delete any existing code in the editor
- Paste the script
- Click Save
- Close the Apps Script tab
- Reload the spreadsheet (onOpen runs on page load)
Step 4: First-Time Authorisation
Each user gets a Google OAuth consent screen on first run. For unverified scripts (most internal scripts), users must click:
Advanced > Go to [Project Name] (unsafe) > Allow
This is a one-time step per user. Warn users about this in your output.
Script Structure Template
Every script should follow this pattern:
/**
* [Project Name] - [Brief Description]
*
* [What it does, key features]
*
* INSTALL: Extensions > Apps Script > paste this > Save > Reload sheet
*/
// --- CONFIGURATION ---
const SOME_SETTING = 'value';
// --- MENU SETUP ---
function onOpen() {
const ui = SpreadsheetApp.getUi();
ui.createMenu('My Menu')
.addItem('Do Something', 'myFunction')
.addSeparator()
.addSubMenu(ui.createMenu('More Options')
.addItem('Option A', 'optionA'))
.addToUi();
}
// --- FUNCTIONS ---
function myFunction() {
// Implementation
}
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.

google-apps-script is a skill published in the GitHub repository jezweb/claude-skills (1,070 stars, last pushed 11d ago), licensed MIT. It adds 89 tokens to every session and 4,646 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
