dos-kernel

A plugin that installs the DOS trust layer for coding-agent fleets: automatic checks, refusal handling, stalled-stream reminders, verification and arbitration tools, and a general skill pack. It requires the dos-kernel Python package.

In plain words
What is it for?
Use it when setting up DOS for one or more cooperating agents, including its hooks, MCP tools, and generic skills.
Why use it?
It puts the kernel's agent safeguards and tools in one install instead of configuring each part separately. The checks help verify outcomes and handle calls the system should refuse.

Plugin for Claude Code

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.

Grade A, and why

dos-kernel 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 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.
