Two +decisions, taken together because neither survives on its own: where the product +starts, and what the new plane is allowed to say. + +## Context + +#32 diagnosed the repository accurately: the deterministic core is focused, and +the product surface around it has diverged. Five planes, three interfaces, and no +stated order between them. Its proposed remedy was to converge on a developer +golden path built from façade commands over the CI gate — `agentsec check`, +`agentsec verify`. + +Trying to write that façade surfaced the problem underneath. + +`agentsec check --target order-agent-staging` needs `order-agent-staging` to +exist. A target is an allowlist entry, a reachable staging agent, and — for the +detection axis to say anything — a Wazuh or OTel backend. That is a security or +platform team's work. The engineer #32 identifies as the primary user cannot +reach the first command of the golden path without it. + +Worse, the ordering is backwards on its own terms. Configuring a target is a +real cost, and nothing in the product told anyone *why it was worth paying* for +their particular repository. The scenario catalogue is generic; the question an +engineer actually has is "is any of this about my code?" + +Meanwhile `project/discovery.py` had been shipped and consumed by nothing. It +produced a careful, traversal-safe inventory of skills, agents, hooks, settings, +instructions and MCP servers — and the only thing reading it was a counts block +in the dashboard header. The material for the missing first step already existed +and was inert. + +Two surfaces were also missing outright. **Tool grants**: a repository can hold +no skills, no agents and no hooks, and still hand a model unattended shell access +in four words of `settings.json`. **Memory / RAG**: retrieved context reaches the +model with the authority of a reviewed instruction and no reviewer diffs it. + +## Decision + +### 1. `agentsec scan` is the entry point + +The golden path starts at a repository, not a target: + +``` +agentsec init → agentsec scan → agentsec scan --verify -t → dashboard +``` + +`scan` requires nothing but a checkout.

It is deliberately neither +a pass nor a failure: it reports that AgentSec found something and cannot settle +it. + +`agentsec scan` exits `0` even with critical risks outstanding.
