# Databricks Execution & Compute

Run code on Databricks. Three execution modes—choose based on workload.

## Execution Mode Decision Matrix

| Aspect | [Databricks Connect](references/1-databricks-connect.md) ⭐ | [Serverless Job](references/2-serverless-job.md) | [Interactive Cluster](references/3-interactive-cluster.md) |
|--------|-------------------|----------------|---------------------|
| **Use for** | Spark code (ETL, data gen) | Heavy processing (ML) | State across tool calls, Scala/R |
| **Startup** | Instant | ~25-50s cold start | ~5min if stopped |
| **State** | Within Python process | None | Via context_id |
| **Languages** | Python (PySpark) | Python, SQL | Python, Scala, SQL, R |
| **Dependencies** | `withDependencies()` | CLI with environments spec | Install on cluster |

### Decision Flow

```
Spark-based code? → Databricks Connect (fastest)
  └─ Python 3.12 missing? → Install it + databricks-connect
  └─ Install fails? → Ask user (don't auto-switch modes)

Heavy/long-running (ML)? → Serverless Job (independent)
Need state across calls? → Interactive Cluster (list and ask which one to use)
Scala/R? → Interactive Cluster (list and ask which one to use)
```


## How to Run Code

**Read the reference file for your chosen mode before proceeding.**

### Databricks Connect (no MCP tool, run locally) → [reference](references/1-databricks-connect.md)

```bash
python my_spark_script.py
```

### Serverless Job → [reference](references/2-serverless-job.md)

```python
execute_code(file_path="/path/to/script.py")
```

### Interactive Cluster → [reference](references/3-interactive-cluster.md)

```python
# Check for running clusters first (or use the one instructed)
list_compute(resource="clusters")
# Ask the customer which one to use

# Run code, reuse context_id for follow-up MCP call
result = execute_code(code="...", compute_type="cluster", cluster_id="...")
execute_code(code="...", context_id=result["context_id"], cluster_id=result["cluster_id"])
```

## MCP Tools

| Tool | For | Purpose |
|------|-----|---------|
| `execute_code` | Serverless, Interactive | Run code remotely |
| `list_compute` | Interactive | List clusters, check status, auto-select running cluster |
| `manage_cluster` | Interactive | Create, start, terminate, delete. **COSTLY:** `start` takes 3-8 min—ask user |
| `manage_sql_warehouse` | SQL | Create, modify, delete SQL warehouses |

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.

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.
