Download remote OpenAPI/Swagger JSON specification from a URL to local file using aptx-ft CLI. TRIGGER when user mentions: (1) fetch/pull/download swagger or openapi from URL, (2) save API spec to openapi.json locally, (3) get API documentation from server, or (4) prepare local input for code generation. DO NOT TRIGGER when: generating code/types from local file, reading existing openapi.json, downloading non-OpenAPI files, or authentication is required.

What this skill does


# Download OpenAPI JSON

Download OpenAPI 3.x JSON specification from a remote URL.

## Prerequisites

```bash
pnpm add -D @aptx/frontend-tk-cli
```

## Usage

```bash
pnpm exec aptx-ft input download --url <url> --output <file>
```

Alternative (without pnpm):

```bash
npx aptx-ft input download --url <url> --output <file>
```

### Example

```bash
pnpm exec aptx-ft input download --url https://api.example.com/swagger.json --output ./openapi.json
```

## Workflow

1. Confirm the OpenAPI URL with user
2. Choose output path (recommended: `./openapi.json`)
3. Execute download command
4. Pass the file path to other skills (generate-models, generate-artifacts)

## Output

- Local OpenAPI JSON file (e.g., `./openapi.json`)

## Boundaries

This skill only handles OpenAPI JSON format downloads:
- Does NOT support YAML format
- Does NOT handle authenticated URLs (Bearer Token, etc.)
- Does NOT support custom request headers
- Only validates JSON syntax, not OpenAPI specification validity

For these cases, download manually and use other tools.

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.
