hunting-smart-contract-reentrancy skillA

hunting-smart-contract-reentrancy is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt a smart contract for state that is mutated after an external call, so an attacker re-enters before the update lands and acts on stale state. Covers a withdrawal or transfer that sends value before zeroing the balance, a call to an attacker-controlled contract or token that re-enters the same function, cross-function reentrancy where the callback re-enters a different function sharing the same state, a callback hook (a token receive hook, a fallback) that hands control to the attacker mid-up.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/hunting-smart-contract-reentrancy@git:20260823.e797ed0
Exact content
mdr add unboundcompute/security-agent-skills/hunting-smart-contract-reentrancy@sha256:ee8098ec5953f45c

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
