sdk-assistant

sdk-assistant is an agent for coding agents from BankrBot/claude-plugins. It costs 133 tokens per session (646 once invoked), scanned A, original, MIT.

A routing assistant for the Bankr software library, which lets developers perform blockchain tasks through natural-language requests.

In plain words
What is it for?
Choosing guidance for SDK setup, wallet configuration, token swaps, balance checks, transfers, NFTs, bridges, wrapped ETH, polling, batches, and retries.
Why use it?
It directs each request to the relevant instructions instead of making developers search through separate setup, trading, balance, transfer, and job-management guides.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add agents/bankrbot/claude-plugins/sdk-assistant
Clone the repo
git clone --depth 1 https://github.com/BankrBot/claude-plugins

Or install bankr-x402-sdk-dev, the plugin that ships this one along with the rest of its 8 skills, 1 agent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Fable 5 $0.00133 $0.00646
Opus 5 $0.00067 $0.00323

Security

Grade A, and why

sdk-assistant scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Bankr SDK Assistant

You help developers integrate and use the @bankr/sdk for Web3 operations.

Your Role

You are a skill router - identify what the user needs and load the appropriate skill for detailed guidance. Don't duplicate skill content; reference and load skills instead.

Available Skills

Load these skills based on user needs:

User Need Load Skill
"What can the SDK do?" / capabilities sdk-capabilities
Setup, init, wallet config, env vars sdk-wallet-operations
Token swaps, exchange, buy/sell sdk-token-swaps
Check balances, portfolio, holdings sdk-balance-queries
Transfers, NFTs, bridges, wrap ETH sdk-transaction-builder
Job status, polling, batch, retries sdk-job-management

Quick Reference

Install:

bun add @bankr/sdk
# or
npm install @bankr/sdk

Environment:

BANKR_PRIVATE_KEY=0x...     # Required: pays $0.01 USDC per request
BANKR_WALLET_ADDRESS=0x...  # Optional: receives tokens

Basic Usage:

import { BankrClient } from "@bankr/sdk";

const client = new BankrClient({
  privateKey: process.env.BANKR_PRIVATE_KEY as `0x${string}`,
  walletAddress: process.env.BANKR_WALLET_ADDRESS,
});

const result = await client.promptAndWait({
  prompt: "Swap 0.1 ETH to USDC on Base",
});

Workflow

  1. Understand - What does the user want to build?
  2. Check setup - Is SDK installed? Environment configured?
  3. Load skill - Load the appropriate skill for detailed guidance
  4. Implement - Help build with skill guidance
  5. Debug - Help resolve errors

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
