A sovereign Go agent runtime for Sylveste: it owns provider selection, tool access, phase state, and terminal UI, running an OODARC workflow where each phase gates its tools in code, not by prompt. Verified by a golden-file parity harness.

Skaffen
Skaffen (GSV-X7) is a sovereign Go agent runtime for Sylveste, GSV's infrastructure-tooling project that orchestrates coding agents by human/machine comparative advantage. Unlike agents that run inside a host IDE, Skaffen owns its own agent loop end-to-end — provider selection, tool access, phase state, evidence emission, and terminal UI all execute inside a local Go binary. Clavain remains the reference Claude Code rig; Skaffen is the runtime path for agents that need to own their own process rather than live inside one. Architecturally, the implementation is split into a phase-agnostic Decide→Act core (internal/agentloop) and an OODARC-aware wrapper (internal/agent) layered on top of it. That wrapper adds gated tool registries scoped per phase — for example, a brainstorm phase is structurally unable to write files while a build phase can — with that boundary enforced by the runtime itself rather than left to system-prompt convention, a notable design commitment to mechanical rather than instructional safety. Skaffen began as a fork of pi_agent_rust and evolved into the Go target of an in-progress migration off an earlier Python agent, Auraken. That migration is the project's current center of gravity, tracked as a sequence of lettered milestones (F1 through F11+) porting discrete subsystems — style fingerprinting, the OODARC prompt builder, preference extraction, and lens/community-graph machinery — from Python into typed Go packages one at a time. Milestone F5, completed July 2026, ported the persona/OODARC context-provider pipeline (Feedback, Lens, Profile, Steering, Style, Session, and Bootstrap providers) into a caching, budget-aware ContextProvider architecture, evidencing the project's parity-harness discipline: proving the Go port matches the Python original's behavior rather than merely reimplementing it. Skaffen sits within GSV's cluster of Culture/Banks-named agent-infrastructure repos (alongside Mawhrin, Masaq, Ockham, Autarch, Derkhan, Demarch sub-apps), most of which resolve as supporting infrastructure for Sylveste rather than standalone creative projects. Status: an active, in-progress migration with several completed lettered milestones and more ahead.
