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 tractorjuice/arc-kitnpx agentmods add plugins/tractorjuice/arc-kit/arckit-claudegit clone --depth 1 https://github.com/tractorjuice/arc-kitGrade A, and why
arckit 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 today.
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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What it installs
The manifest is a name and a version. 9 agents travel with it, and installing the plugin installs all of them — 1,773 tokens a session between them. Each is measured on its own page, and each can be installed alone.
- Agent arckit-datascout A 398 tokens
- Agent arckit-aws-research A 389 tokens
- Agent arckit-azure-research A 388 tokens
- Agent arckit-competitors-writer A 101 tokens
- Agent arckit-cloud-research-writer A 115 tokens
- Agent arckit-datascout-writer A 89 tokens
- Agent arckit-aws-research-reader B 101 tokens
- Agent arckit-azure-research-reader B 101 tokens
- Agent arckit-datascout-reader B 91 tokens
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.
