mailagent skillA

mailagent is agent-read markdown (skill) from hashgraph-online/awesome-codex-plugins: Temporary inboxes for agent signup QA — create disposable addresses, wait for verification email, extract OTP or magic links. Use when automating signup, login, or email verification without parsing HTML manually..

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 hashgraph-online/awesome-codex-plugins/mailagent@v0.2.16
Exact content
mdr add hashgraph-online/awesome-codex-plugins/mailagent@sha256:342745ffa80e36a9

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.
