Bankr x402 SDK - Capabilities

Bankr x402 SDK - Capabilities is a skill for Claude Code from BankrBot/claude-plugins. It costs 90 tokens per session (833 once invoked), scanned A, original, MIT.

A reference for the operations supported by the Bankr SDK, a software library that turns natural-language requests into blockchain transaction data. It covers swaps, transfers, bridges between EVM-compatible blockchains, leveraged positions, NFTs, and staking.

In plain words
What is it for?
Use it to find supported prompts and operations for moving or exchanging tokens, bridging funds, managing NFTs, opening or closing leveraged positions, and staking BNKR.
Why use it?
It removes guesswork about which requests the SDK understands and how to phrase them. Developers can check supported operation types before building an integration.

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.

Security

Grade A, and why

Bankr x402 SDK - Capabilities 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 6d 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.

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.
