README

**Two questions, two answers.** What are your agents *allowed to do*? And what do they *run on*?

[Own Your Agent Security](#own-your-agent-security) · [Own Your Stack](#own-your-stack) · [The operation](#the-operation) · [Receipts](#receipts) · [Who](#thomas-sprayberry)

Agents are useful because they act. That is also the whole risk: a tool call that runs a shell, a skill fetched from a marketplace, a browser session on a hostile page. **Own Your Agent Security** is the answer to the first question: deterministic gates around what an agent may do, running in production here. **Own Your Stack** is the answer to the second: the subscription you already pay for, on your own box, routed and guarded by tools you can read in a weekend, instead of intelligence rented by the token through someone else's pipes.

Everything below is open source, and everything below runs the operation that ships it.

Own Your Agent Security

An agent's tool calls pass through redstamp, its skills through truecopy, and plumbline watches the whole sequence from out of band before anything reaches tools, skills or the web.

**Don't trust agents by default.** A firewall for every tool call, a supply-chain gate for every skill and MCP server, and a trajectory monitor watching the whole sequence. Each closes a different hole; together they are one layered defense.
