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 jovesun-lab/arcgramnpx agentmods add plugins/jovesun-lab/arcgram/arcgramgit clone --depth 1 https://github.com/jovesun-lab/arcgramGrade A, and why
arcgram 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 2d ago.
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": "arcgram",
"version": "2.0.0",
"description": "Surface an AI agent's thinking and make it auditable. Instead of a wall of prose, your agent commits its reasoning to typed nodes and explicit edges — real data you inspect and correct node by node, converging on ground truth that carries across turns, sessions, and agents. Use it as an agent harness or operating frame: propose → draw → self-audit → fix, human in the loop. Delivered as a single standalone interactive HTML file — no build step, no npm, no CDN, no runtime; open in any browser. Ships the Arcgram authoring skill plus the Checkpoint, Reconcile, and Validate self-check skills. Agent-neutral: reads as plain markdown on any framework.",

What ships with it
1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
