# Model Brain Use this skill when the goal is to choose the right model for a single message or action. ## Core policy - Prefer `zero-llm` when a deterministic skill or script can do the job. - Use the cheapest adequate model for low-risk work. - Use `bankr/claude-sonnet-4.5` for routine wallet and treasury operations that are important but still normal. - Escalate to `bankr/claude-opus-4.6` only for explicitly high-stakes, security-sensitive, or ambiguous wallet flows. - Use `bankr/gpt-5.2-codex` for coding-heavy implementation work. - Keep routing deterministic and rule-based before adding any LLM-on-LLM behavior. - Treat the output as a routing recommendation, not as transaction authority. ## Default routes - `zero-llm` - deterministic skills like `pet-me-master` - shellable tasks with no reasoning need - `bankr/minimax-m2.5` - casual chat, lightweight rewriting, simple summaries, low-risk classification - `bankr/claude-sonnet-4.5` - general reasoning, planning, product thinking, routine wallet ops - `bankr/gpt-5.2-codex` - coding-heavy patching, repo surgery, implementation details - `bankr/gemini-3-pro` - long-context synthesis and broad document digestion - `bankr/gemini-3-flash` - lightweight vision and quick multimodal triage - `bankr/claude-opus-4.6` - explicitly high-stakes wallet actions, security reviews, tricky architecture, final escalation ## Routing workflow 1. Check whether the request can be handled by a deterministic skill or script. 2. Classify the task: `chat`, `code`, `wallet`, `vision`, `long-context`, or `deterministic`. 3. Mark whether the request is high-stakes. 4. Route to the cheapest safe model. 5. Return the primary route, fallback route, and a short reason. ## Quick start ```bash python3 {baseDir}/scripts/route_message.py --text "pet all my 53 gotchis" --json python3 {baseDir}/scripts/route_message.py --text "rewrite this x thread shorter" --json python3 {baseDir}/scripts/route_message.py --text "swap ETH to USDC and send to treasury" --json bash {baseDir}/scripts/select_model.sh --text "build this feature in the repo" --mode summary ``` ## Wrapper entrypoint Use `scripts/select_model.sh` when you want a simple aaigotchi-friendly wrapper before model selection. It can emit just the route, full JSON, or shell-style env lines. ## References - Read `references/routing-table.md` for the routing rules and escalation thresholds. - Read `references/bankr-models.md` for the current Bankr model inventory and aaigotchi default.
