# CORE + builder-II local agent hints
- temperature 0 everywhere
- Read AGENTS.md, GROK.md, docs/runtime_contracts.md before edits
- Proposals are SPECULATIVE until `builder verify` passes
- Use skills: core-governed-coding, core-verify-loop, core-pre-edit-sweep, core-handoff
- Slash: /explore /implement /review /verify /handoff /plan
- Switch model: builder switch-model fast|primary (one model on M1 16GB)
- versor_condition(F) < 1e-6 — refuse cosine/ANN/HNSW in vault
