token-approval-safety skillA

token-approval-safety is agent-read markdown (skill) from nirholas/three.ws: Guide to ERC-20 token approvals — how they work, why unlimited approvals are risky, how to check and revoke approvals, and best practices. Use when helping users manage approvals, audit wallet security, or understand approval-related risks..

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 nirholas/three.ws/token-approval-safety@git:20260501.87cefc9
Exact content
mdr add nirholas/three.ws/token-approval-safety@sha256:55a909053cc48ce5

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.
