# nisse-dev The Dev Agent (Part B of the Nisse system). A thin application over the shared `nisse-core` package. **Read the architecture before making design decisions here:** `docs/Architecture-Build-Spec.md` at the repo root. Part B specifies this agent; Part A specifies the library contracts it depends on. Requirements that look like free choices in this package — gating structure, state durability, LLM access paths — are usually settled there.
