local-node-validation

local-node-validation is a skill for Claude Code, Codex from 0xMiden/agent-tools. It costs 43 tokens per session (4,448 once invoked), scanned C, original, no licence file.

A validation guide for checking Miden smart contracts against a local node, which is a running copy of the contract network.

In plain words
What is it for?
Use it after MockChain tests pass to set up the node, adapt Rust binaries, verify state, and troubleshoot contract checks.
Why use it?
It catches problems that mocked tests may miss before relying on a real node.

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 C, and why

local-node-validation scanned grade C with 1 finding 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 5d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

**Use a fresh, explicitly disposable test data directory for each validation session.** Stale stores can cause conflicts, deserialization errors, and misleading test results. Preserve existing stores, exports, and keysto

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.
