Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
/plugin marketplace add trtmn/agent-pluginsnpx agentmods add plugins/trtmn/agent-plugins/imsggit clone --depth 1 https://github.com/trtmn/agent-pluginsGrade A, and why
imsg 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 yesterday.
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
{
"name": "imsg",
"version": "1.0.0",
"description": "Terminal-based iMessage and SMS management via the command line. Use this skill whenever the user mentions texting, messaging, iMessage, SMS, conversations, chat history, message backups, or any interaction with their Messages database. Trigger for requests to send/receive messages, view conversation history, list chats, watch for incoming texts, export or backup messages, or manage iMessage/SMS data—even if the user doesn't explicitly say \"iMessage\" or \"SMS\". This is the right skill for anything involving text messages, group chats, or the Messages app accessed from the terminal."
}
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.
