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.

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 | $0.00023 | $0.01280 |
| Opus 5.5 | $0.00009 | $0.00512 |
| Sonnet 5.5 | $0.00005 | $0.00256 |
| Haiku 4.5 | $0.00002 | $0.00128 |
Grade A, and why
coding-standards 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.
How it starts
The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coding Standards
Naming Conventions
| Tip | Format | Ornek |
|---|---|---|
| Variable | camelCase | userName, itemCount |
| Function | camelCase, verb-first | getUserById, calculateTotal |
| Class/Type | PascalCase | UserService, OrderItem |
| Constant | UPPER_SNAKE | MAX_RETRIES, API_URL |
| File | kebab-case | user-service.ts, order-item.ts |
| Boolean | is/has/should prefix | isActive, hasPermission |
Immutability
// YANLIS: Mutate
user.name = newName;
items.push(newItem);
// DOGRU: Yeni obje
const updated = { ...user, name: newName };
const newItems = [...items, newItem];
Error Handling
// Custom error class
class AppError extends Error {
constructor(public code: string, message: string, public statusCode = 500) {
super(message);
}
}
// Try-catch with specific errors
try {
const result = await riskyOperation();
return result;
} catch (error) {
if (error instanceof ValidationError) {
throw new AppError('VALIDATION', error.message, 400);
}
throw new AppError('INTERNAL', 'Unexpected error', 500);
}
Function Rules
- Max 50 satir, tek sorumluluk
- Max 3 parametre (fazlasi obje olarak)
- Early return (nested if yerine guard clause)
- Pure function tercih et (side effect yok)
// YANLIS: Deep nesting
function process(user) {
if (user) {
if (user.isActive) {
if (user.hasPermission) {
return doWork(user);
}
}
}
}
// DOGRU: Early return
function process(user) {
if (!user) return null;
if (!user.isActive) return null;
if (!user.hasPermission) return null;
return doWork(user);
}
SOLID Principles
| Prensip | Kural |
|---|---|
| S - Single Responsibility | Her sinif/fonksiyon tek is |
| O - Open/Closed | Extension'a acik, modification'a kapali |
| L - Liskov Substitution | Alt tip, ust tipin yerine gecebilmeli |
| I - Interface Segregation | Kucuk, specific interface'ler |
| D - Dependency Inversion | Abstraction'a baglan, concrete'e degil |
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.
- 1mo ago First seen · 171 lines · 23 tokens per session scan A 745ad236840d
coding-standards is a skill published in the GitHub repository vibeeval/vibecosystem (540 stars, last pushed 2mo ago), licensed MIT. It adds 23 tokens to every session and 1,280 once invoked, about $0.0001 per session on Opus 5.5. 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.

cpp-coding-standards
C++ coding standards based on the C++ Core Guidelines (isocpp.github.io). Use when writing, reviewing, or refactoring C++ code to enforce modern, safe, and idiomatic practices.
code-quality
Agents should invoke this skill for code reviews, linting/formatting setup, maintainability checks, complexity concerns, warning cleanup, coding standards, or quality gates in Rust, TypeScript, Python, shell, and mixed repos.
transformers-js
Run Hugging Face models in JavaScript or TypeScript with Transformers.js, WebGPU, or WASM across browser, Node.js, Bun, and Deno. Use for client-side or JS-runtime inference, not Python training.
mcp-builder
Guide the creation of high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when the user wants to build an MCP server to integrate an external API or service, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
