reentrancy-pattern-analysis

reentrancy-pattern-analysis is a plugin for Claude Code from quillai-network/quillshield_skills. Its manifest loads nothing; the 1 skill it bundles cost 100 tokens per session together, scanned A, original, MIT.

A security checker for reentrancy in smart contracts, where an external call can unexpectedly enter the contract again before the first operation finishes. It checks classic, cross-function, cross-contract, and read-only forms, including token callbacks.

In plain words
What is it for?
Use it to review withdrawals, token callbacks, external calls, and any contract flow where another contract can run code during an operation.
Why use it?
It helps find cases where state is changed in an unsafe order or an external contract can call back into sensitive code. It also checks the common checks-effects-interactions pattern.

Security

Grade A, and why

reentrancy-pattern-analysis 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 7d 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 installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 100 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
