audit

audit is a skill for Claude Code, Codex from ArcticWolfXZ/claude-codex-crypto-devkit. It costs 0 tokens per session (108 once invoked), scanned A, original, MIT.

A checklist for reviewing EVM and Solana smart contracts, which are programs that run on blockchains. It checks common security issues such as unauthorized access, unsafe external calls, and account permissions.

In plain words
What is it for?
Use it when running /crypto-devkit:audit to check contracts and produce an AUDIT.md report in the project root.
Why use it?
It helps identify security weaknesses before a smart contract is released or changed. The review focuses on recurring blockchain-specific failure cases.

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

audit 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

Smart contract audit pack

When user runs /crypto-devkit:audit, check:

EVM

  • Reentrancy (CEI pattern)
  • onlyOwner / roles / timelock
  • Oracle staleness & manipulation
  • Proxy: storage collision, initializer
  • External calls: return value checks

Solana

  • Account owner & signer
  • PDA bump canonicalization
  • CPI privilege escalation
  • Rent-exempt closure

Output: markdown report AUDIT.md in project root.

Changes

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.
