What this skill does


# /bun:build

Bundle JavaScript/TypeScript or compile to standalone executable.

## When to Use This Skill

| Scenario | Use this skill | Alternative |
|----------|---------------|-------------|
| Quick production bundle of an entry point | Yes | N/A |
| Compiling to a standalone executable | Yes | N/A |
| Building for a specific target (browser/bun/node) | Yes | N/A |
| Configuring complex build pipelines | No - use `bun-development` | Full build configuration guidance |
| Running project build scripts (`bun run build`) | No - use `bun-development` | N/A |

## Parameters

- `entry` (required): Entry point file
- `--compile`: Create standalone executable
- `--minify`: Minify output

## Execution

**Production bundle:**
```bash
bun build $ENTRY --outdir=dist --minify --sourcemap=external
```

**Standalone executable:**
```bash
bun build --compile --minify $ENTRY --outfile={{ OUTFILE | default: "app" }}
```

**Development bundle:**
```bash
bun build $ENTRY --outdir=dist --sourcemap=inline
```

## Build Targets

```bash
# Browser (default)
bun build $ENTRY --target=browser --outdir=dist

# Bun runtime
bun build $ENTRY --target=bun --outdir=dist

# Node.js
bun build $ENTRY --target=node --outdir=dist
```

## Agentic Optimizations

| Context | Command |
|---------|---------|
| Prod bundle | `bun build ./src/index.ts --outdir=dist --minify --sourcemap=external` |
| Compile to exe | `bun build --compile --minify ./app.ts --outfile myapp` |
| Dev bundle | `bun build ./src/index.ts --outdir=dist --sourcemap=inline` |
| Browser target | `bun build ./src/index.ts --target=browser --outdir=dist` |
| Node target | `bun build ./src/index.ts --target=node --outdir=dist` |

## Post-build

1. Report output file sizes
2. List generated files in output directory
3. For --compile: verify executable runs with `./app --help` or similar

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.
