What this skill does


# Safety & Access Control

Comprehensive safety guidance for using the Bankr API and CLI.

## API Key Types

Bankr uses a single key format (`bk_...`) with capability flags:

| Flag | Controls | Default |
|------|----------|---------|
| `agentApiEnabled` | `/agent/*` endpoints | false |
| `llmGatewayEnabled` | LLM Gateway at `llm.bankr.bot` | false |
| `readOnly` | Restricts agent to read-only tools | false |

Manage flags at [bankr.bot/api](https://bankr.bot/api).

## Read-Only API Keys

When `readOnly: true`, all write tools are filtered from the agent session:

**Allowed:** Balances, prices, analytics, portfolio, research
**Blocked:** Swaps, transfers, NFT purchases, staking, orders, token launches, leverage, Polymarket bets, claims

The `/agent/sign` and `/agent/submit` endpoints return 403 for read-only keys.

## IP Whitelisting

Set `allowedIps` on your API key to restrict usage to specific IPs. Requests from non-whitelisted IPs are rejected with 403.

- Empty array = all IPs allowed (default)
- Non-empty array = only listed IPs can use the key

## Dedicated Agent Wallet

When building autonomous agents, create a **separate Bankr account** rather than using your personal wallet:

- **Limited exposure** — compromised key only exposes agent wallet funds
- **Clear accounting** — agent transactions isolated from personal activity
- **Independent controls** — apply stricter access controls without affecting personal use
- **Easy revocation** — disable agent account without disrupting primary wallet

### Recommended Funding

| Chain | Gas Buffer | Trading Capital |
|-------|-----------|-----------------|
| Base | 0.01-0.05 ETH | As needed |
| Polygon | 5-10 MATIC | As needed |
| Ethereum | 0.05-0.1 ETH | As needed |
| Solana | 0.1-0.5 SOL | As needed |

## Rate Limits

| Tier | Daily Limit |
|------|-------------|
| Standard | 100 messages/day |
| Bankr Club | 1,000 messages/day |
| Custom | Set per API key |

Reset window is 24 hours from first message (rolling), not midnight.

## Key Management

- Store keys in environment variables (`BANKR_API_KEY`, `BANKR_LLM_KEY`), never in source code
- Add `~/.bankr/` and `.env` to `.gitignore`
- Rotate keys periodically at [bankr.bot/api](https://bankr.bot/api)
- Revoke immediately if compromised
- Use separate keys for Agent API vs LLM Gateway if needed

## Transaction Safety

- **Test first** — small amounts on Base/Polygon before scaling
- **Verify recipients** — double-check addresses before transfers
- **Gas buffer** — keep enough native tokens for gas
- **Immediate execution** — `/agent/submit` executes with no confirmation prompt
- **Understand calldata** — verify trusted source for arbitrary transactions

## Pre-Deployment Checklist

- Use a dedicated agent wallet, not your personal account
- Fund with limited amounts appropriate to purpose
- Set read-only if agent only queries data
- Configure IP whitelisting for server-side agents
- Store keys in environment variables
- Test with small amounts first
- Implement error handling for rate limits (429) and access control (403)

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.
