What this skill does


## Troubleshooting

If requests fail, run `zero doctor check-connector --env-name HUNTER_TOKEN` or `zero doctor check-connector --url https://api.hunter.io/v2/account --method GET`.

## How to Use

Hunter authenticates with an API key passed as the `api_key` query
parameter on every request. The base URL is `https://api.hunter.io`.

### 1. Domain search (find all emails at a company)

```bash
curl -s -G "https://api.hunter.io/v2/domain-search" \
  --data-urlencode "domain=stripe.com" \
  --data-urlencode "limit=10" \
  --data-urlencode "api_key=$HUNTER_TOKEN"
```

### 2. Email finder (guess a specific person's email)

```bash
curl -s -G "https://api.hunter.io/v2/email-finder" \
  --data-urlencode "domain=stripe.com" \
  --data-urlencode "first_name=Patrick" \
  --data-urlencode "last_name=Collison" \
  --data-urlencode "api_key=$HUNTER_TOKEN"
```

### 3. Email verifier

```bash
curl -s -G "https://api.hunter.io/v2/email-verifier" \
  --data-urlencode "[email protected]" \
  --data-urlencode "api_key=$HUNTER_TOKEN"
```

### 4. Email count for a domain (free, no quota)

```bash
curl -s -G "https://api.hunter.io/v2/email-count" \
  --data-urlencode "domain=stripe.com" \
  --data-urlencode "api_key=$HUNTER_TOKEN"
```

### 5. Account info / remaining quota

```bash
curl -s -G "https://api.hunter.io/v2/account" \
  --data-urlencode "api_key=$HUNTER_TOKEN"
```

## Guidelines

1. **Confidence score** — every result includes `confidence` (0-100); treat <50 as low-quality before reaching out.
2. **Email-finder vs domain-search** — domain-search returns everyone Hunter knows; email-finder is a targeted single-person lookup that costs more credits.
3. **Always verify before sending** — use `email-verifier` immediately after `email-finder` to avoid bounces.
4. **Quota is per request, not per result** — fetching 100 emails costs 1 domain-search credit.

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.
