# Domino Model Endpoints Skill

This skill provides comprehensive knowledge for deploying and monitoring model API endpoints in Domino Data Lab.

## Key Concepts

### Model Endpoints Overview

Domino Model Endpoints provide:
- REST API for model predictions
- Automatic scaling and load balancing
- Version management
- Built-in monitoring with Grafana
- Authentication via API tokens

### Endpoint Lifecycle

```
Train Model → Register → Deploy Endpoint → Monitor → Update Version
```

## Related Documentation

- [DEPLOY-ENDPOINT.md](./DEPLOY-ENDPOINT.md) - Creating model APIs
- [MONITORING.md](./MONITORING.md) - Grafana, metrics, alerts
- [SCALING.md](./SCALING.md) - GPU inference, Triton, scaling

## Environment Requirements

**Important:** Model APIs use the **default environment** set for your project. The environment must have the `uwsgi` Python package installed for model endpoints to work.

### Required Package
```dockerfile
# Add to your environment's Dockerfile instructions
RUN pip install uwsgi
```

Or in requirements.txt:
```
uwsgi
```

### Setting Default Environment
1. Go to **Project Settings** → **Execution Preferences**
2. Set the **Default Environment** that includes `uwsgi`
3. This environment will be used for all Model API deployments

## Quick Start

### 1. Create Endpoint Function

```python
# model.py
def predict(features):
    """
    Domino calls this function for predictions.

    Args:
        features: Input data (dict, list, or primitive)

    Returns:
        JSON-serializable prediction result
    """
    import pickle

    # Load model (cached after first call)
    with open('model.pkl', 'rb') as f:
        model = pickle.load(f)

    prediction = model.predict([features])
    return {"prediction": prediction.tolist()}
```

### 2. Deploy via Domino UI

1. Go to **Publish** → **Model APIs**
2. Click **New Model**
3. Configure:
   - Name: `my-classifier`
   - File: `model.py`
   - Function: `predict`
   - Environment: Select compute environment
4. Click **Publish**

### 3. Call the Endpoint

```bash
curl -X POST \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -d '{"data": {"features": [1.0, 2.0, 3.0]}}' \
  https://your-domino.com/models/abc123/latest/model
```

## Environment Variables

When calling endpoints from apps:

| Variable | Description |
|----------|-------------|
| `MODEL_API_URL` | Full endpoint URL |
| `MODEL_API_TOKEN` | Bearer token for authentication |

## Key Metrics to Monitor

| Metric | Target |
|--------|--------|
| Latency P50 | < 100ms |
| Latency P99 | < 500ms |
| Error Rate | < 1% |
| CPU Usage | < 80% |
| Memory | Stable (no growth) |

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".

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.

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.
