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/preflight-checkgit clone --depth 1 https://github.com/trtmn/agent-pluginsGrade A, and why
preflight-check 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": "preflight-check",
"version": "1.0.0",
"description": "Validate all external service connections before starting work. Trigger this skill proactively whenever a task involves GitHub (gh CLI, repos, PRs, issues), Atlassian (Jira, Confluence, any mcp__claude_ai_Atlassian__ tool), or UniFi (network management, UNIFI_API_KEY). Also trigger when the user explicitly says \"preflight\", \"check connections\", \"validate services\", \"are my APIs working\", \"check my integrations\", \"test my setup\", or \"verify access\". If any external service call fails unexpectedly during a task, trigger this skill to diagnose the issue. The goal is to catch auth problems early rather than failing mid-task."
}
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.
