What this skill does


# mempool.space

Open-source mempool explorer + REST/WebSocket APIs. Industry-leading
mempool visibility.

Repo: `github.com/mempool/mempool`.

## Features

- **Mempool blocks projection**: shows next ~10 blocks with median
  fees per virtual block.
- **Fee estimates**: `/api/v1/fees/recommended` returns
  `{fastestFee, halfHourFee, hourFee, economyFee, minimumFee}`.
- **Address history**: similar to Esplora.
- **Lightning visualizer**: graph view, channel info.
- **Mining stats**: pool distribution, block templates, hashrate.
- **Accelerator**: paid service to push tx into next block.

## Self-host

```bash
docker compose up -d
```

Stack: Bitcoin Core + electrs-fork (mempool-electrs) + Node.js backend
+ Nginx + frontend.

Disk ~1-2 TB, RAM ~4-8 GB recommended.

## REST API

```
GET /api/v1/fees/recommended
GET /api/mempool
GET /api/v1/fees/mempool-blocks
GET /api/tx/<txid>/status
GET /api/block/<hash>
GET /api/address/<addr>
GET /api/v1/mining/pools/24h
```

Full docs: `mempool.space/docs/api/rest`.

## WebSocket

`/api/v1/ws` — subscribe to live blocks, mempool, address.

```js
const ws = new WebSocket("wss://mempool.space/api/v1/ws");
ws.send(JSON.stringify({ action: "want", data: ["blocks", "mempool-blocks"] }));
```

## Accelerator

Paid via Lightning. Operator publishes the tx with high fee priority
(via mempool.space's pool partnerships). Useful when:
- Tx is stuck due to ancestor / no RBF.
- Need confirmation in next 1-2 blocks.

Cost: usually few dollars to ~$50, depending on size + urgency.

## Compared to Esplora

| Aspect | mempool.space | Esplora |
|--------|---------------|---------|
| Mempool detail | best | basic |
| Fee estimation | best | OK |
| Lightning view | yes | partial |
| Mining stats | rich | basic |
| API spec compatibility | mempool.space-specific | spec defined |

## Common bugs

- Self-hosted: full sync takes days; first IBD + indexing.
- Public API rate-limited; for serious integrations, run your own
  or pay for premium.
- WebSocket reconnect logic essential — connections drop.

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.
