RuvNet Brain — a downloadable, source-grounded brain for Claude Code over Reuven Cohen's (rUv's) RuvNet stack: RuVector/RVF, Ruflo, AgentDB, RuLake, SPARC + 21 building blocks. Grounds Claude in real source via one MCP tool (search_ruvnet), so it builds with the stack instead of drifting off it.

The autonomous build contract, out of the box — "/brain-build " activates the disciplined hands-off build power users used to hand-write a standing prompt for. Use when the user says "/brain-build", "brain build", "build this autonomously", "build this hands-off", "loop until it's done", "don't ask me, just build it"…

Open the RuvNet Brain Console for "/rvbc", "/rvcb", "/brain-console", or "/ruvnet-brain:configure". Use when the user asks to open, configure, inspect, or view the Brain Console. It opens the live local page in the background; the page is read-only until the user clicks a clearly explained, reversible action.

Metaprompting assistant — "/brain-prompt " turns a rough ask into "the right prompt": a complete, tuned master prompt with SPARC phases, per-phase rubrics, standing rules, and cost guardrails, ready to paste or run. Use when the user says "/brain-prompt", "brain prompt", "write me the right prompt for this", "turn…

Score ANY repository 0-100 across 8 dimensions using the exact evidence-or-it-didn't-happen scorecard RuvNet-Brain applies to itself. Use when the user says "score this repo", "score my repo", "scorecard", "brain-score", "how good is this codebase", "rate this project", "audit quality", or asks for an honest 0-100…

Fail-closed exact-artifact release and deployment authority. Use before saying a release is ready, pushing a release commit, publishing npm packages, creating GitHub releases, deploying production, closing release-blocking issues, or claiming all gates are green.

Use whenever a task involves the RuvNet / rUv ecosystem (Ruflo, RuVector/RVF, AgentDB, RuLake, RuView, agentic-flow, agenticow, SAFLA, QuDAG, DAA, ruv-fann, FACT, SynthLang, SPARC, or any of rUv's 20+ repos) — OR whenever you are asked to build, implement, add, refactor, enhance, or fix ANYTHING, in any repo, on any…

Open the RuvNet Brain Console in Claude Code and Codex when the user says "Configure RuvNet Brain", mentions "rvbc", asks for the Brain Console, or wants to configure or inspect RuvNet Brain. Claude Code supports /rvbc; Codex invokes the native $ruvnet-brain:rvbc skill.

Show the MetaHarness routing ledger inline — which model each task was routed to, what it displaced, and the percentage + dollars saved — plus the learned router's training state. Use when the user says "savings", "show my savings", "metaharness report", "metaharness/report", "routing report", "routing receipts", "who…

Explain what is new in the installed RuvNet Brain release from live version metadata and the curated release notes. Use for "/whats-new", "what's new", "what changed", "new release", or "show me the latest Brain improvements". Never claim a 4.0 version unless the installed version actually starts with 4.
