What this skill does


# Noop Entity Generator

This skill generates complete CRUD infrastructure for new domain entities.

## When Claude Should Use This

Automatically use this skill when the user wants to:
- Add a new resource/entity to their API
- Create a new database table with CRUD operations
- Add new API endpoints following noop patterns
- Mentions "add entity", "new model", "new resource"

## Files Generated

For entity `Product`:

| File | Purpose |
|------|---------|
| `src/types/product.types.ts` | Type definitions |
| `src/db/pg/ProductOps.ts` | Database operations |
| `src/handlers/productHandler.ts` | HTTP handlers |
| Migration SQL | Table creation |

## Files Updated

| File | Changes |
|------|---------|
| `src/db/pg/PgClientStore.ts` | Register ProductOps |
| `src/routes.ts` | Add CRUD routes |
| `src/types/index.ts` | Export types |

## Naming Conventions

| Input | Output | Example |
|-------|--------|---------|
| Entity | PascalCase | `Product` |
| Type file | `{entity}.types.ts` | `product.types.ts` |
| Ops file | `{Entity}Ops.ts` | `ProductOps.ts` |
| Handler | `{entity}Handler.ts` | `productHandler.ts` |
| Table | snake_case plural | `products` |
| Routes | lowercase plural | `/api/v1/products` |
| Store prop | camelCase plural | `dbStore.products` |

## Templates

### Types
```typescript
export interface ProductInfo {
  id: string
  name: string
  description?: string
  organizationId: string
  createdAt: Date
  updatedAt: Date
}

export type CreateProductInput = Omit<ProductInfo, 'id' | 'organizationId' | 'createdAt' | 'updatedAt'>
```

### Ops Class (CRITICAL: organizationId required on ALL methods)
```typescript
export class ProductOps {
  async create(data: CreateProductInput, organizationId: string): Promise<ProductInfo> {
    if (!organizationId) throw new Error('organization_id is required')
    // parameterized INSERT
  }

  async getById(id: string, organizationId: string): Promise<ProductInfo | undefined> {
    if (!organizationId) throw new Error('organization_id is required')
    // SELECT with org filter
  }

  private mapRowToProduct(row: DbProductRow): ProductInfo { }
}
```

### Handler
```typescript
export const create = asyncHandler(async (req, res) => {
  const { name, description } = req.body
  if (!name) throw createError.requiredField('name')

  const dbStore = getDbStore()
  const item = await dbStore.products.create(
    { name, description },
    req.user.organizationId
  )

  return sendSuccess(res, item, 'Product created', 201)
})
```

### Migration SQL
```sql
CREATE TABLE products (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
  name VARCHAR(255) NOT NULL,
  description TEXT,
  organization_id UUID NOT NULL,
  created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
  updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
);

CREATE INDEX idx_products_organization ON products(organization_id);
```

### Routes
```typescript
app.get(`${API_PREFIX}/products`, productHandlers.list)
app.post(`${API_PREFIX}/products`, productHandlers.create)
app.get(`${API_PREFIX}/products/:id`, productHandlers.get)
app.put(`${API_PREFIX}/products/:id`, productHandlers.update)
app.delete(`${API_PREFIX}/products/:id`, productHandlers.remove)
```

## Verification

- `npm run typecheck` passes
- `npm run lint` passes
- Types exported from index
- Ops registered in PgClientStore
- Routes registered

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.

resend-cli

Included

Use this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.

alibabacloud-odps-maxframe-coding

Included

Use this skill for MaxFrame SDK development and documentation navigation on Alibaba Cloud MaxCompute (ODPS). Helps answer MaxFrame API, concept, official example, and supported pandas API questions; create data processing programs; read/write MaxCompute tables; debug jobs (remote or local); and build custom DPE runtime images. Trigger when users mention MaxFrame, MaxCompute with MaxFrame, ODPS table processing, DPE runtime, MaxFrame docs/examples, DataFrame/Tensor operations, or GPU runtime setup. Works for both English and Chinese queries about Alibaba Cloud data processing with MaxFrame.
