What is it for?
Use it to change onboarding, wallet and signer behavior, sponsored transactions, ERC-20 token operations, staking, transaction builders, tests, documentation, or examples in Starkzap.
Why use it?
It provides a map of the Starkzap codebase and directs work to the relevant implementation areas instead of treating the project like a generic Starknet SDK.

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

starkzap-sdk 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 11d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/privy-signing-debug.ts, scripts/staking-pool-discovery.ts, scripts/wallet-execute-example.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Starkzap SDK

Project-focused guide for https://github.com/keep-starknet-strange/starkzap.

Use this skill when requests involve Starkzap SDK code, examples, or docs.

When to Use

Trigger for tasks like:

  • "Add a new onboarding flow in Starkzap"
  • "Fix sponsored transaction behavior in wallet.execute"
  • "Update staking pool logic or validator presets"
  • "Patch Privy signer/server integration"
  • "Review Starkzap tests/docs/examples"

When NOT to Use

  • Generic Starknet SDK work outside the Starkzap codebase.
  • Cairo contract authoring, deployment operations, or security audits.

Quick Start

  1. Open the target Starkzap repository paths below and choose the smallest workflow surface first.
  2. Use skills catalog when the task crosses into generic Starknet wallet, deployment, or audit flows.

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.
