--- name: smart-model-switching description: >- Auto-route tasks to the cheapest Claude model that works correctly. Three-tier progression: Haiku → Sonnet → Opus. Classify before responding. HAIKU (default): factual Q&A, greetings, reminders, status checks, lookups, simple file ops, heartbeats, casual chat, 1-2 sentence tasks. ESCALATE TO SONNET: code >10 lines, analysis, comparisons, planning, reports, multi-step reasoning, tables, long writing >3 paragraphs, summarization, research synthesis, most user conversations. ESCALATE TO OPUS: architecture decisions, complex debugging, multi-file refactoring, strategic planning, nuanced judgment, deep research, critical production decisions. Rule: If a human needs >30 seconds of focused thinking, escalate. If Sonnet struggles with complexity, go to Opus. Save 50-90% on API costs by starting cheap and escalating only when needed. author: "OpenClaw Community" version: 1.0.0 homepage: https://clawhub.com metadata: openclaw: emoji: "💰" --- # Smart Model Switching **Three-tier Claude routing: Haiku → Sonnet → Opus** Start with the cheapest model. Escalate only when needed. Save 50-90% on API costs. ## The Golden Rule > If a human would need more than 30 seconds of focused thinking, escalate from Haiku to Sonnet. > If the task involves architecture, complex tradeoffs, or deep reasoning, escalate to Opus. ## Cost Reality | Model | Input | Output | Relative Cost | |-------|-------|--------|---------------| | Haiku | \$0.25/M | \$1.25/M | 1x (baseline) | | Sonnet | \$3.00/M | \$15.00/M | 12x | | Opus | \$15.00/M | \$75.00/M | 60x | **Bottom line:** Wrong model selection wastes money OR time. Haiku for simple, Sonnet for standard, Opus for complex. --- ## 💚 HAIKU — Default for Simple Tasks **Stay on Haiku for:** - Factual Q&A — "what is X", "who is Y", "when did Z" - Quick lookups — definitions, unit conversions, short translations - Status checks — calendar, file reads, session monitoring - Heartbeats — periodic checks, HEARTBEAT_OK responses - Memory & reminders — "remember this", "remind me to..." - Casual conversation — greetings, small talk, acknowledgments - Simple file ops — read, list, basic writes - One-liner tasks — anything answerable in 1-2 sentences ### NEVER do these on Haiku - ❌ Write code longer than 10 lines - ❌ Create comparison tables - ❌ Write more than 3 paragraphs - ❌ Do multi-step analysis - ❌ Write reports or proposals --- ## 💛 SONNET — Standard Work (The Workhorse) **Escalate to Sonnet for:** ### Code & Technical - Code generation — write functions, build features, scripts - Code review — PR reviews, quality checks - Debugging — standard bug investigation - Documentation — README, comments, user guides ### Analysis & Planning - Analysis & evaluation — compare options, assess trade-offs - Planning — project plans, roadmaps, task breakdowns - Research synthesis — combining multiple sources - Multi-step reasoning — "first... then... finally" ### Writing & Content - Long-form writing — reports, proposals, articles (>3 paragraphs) - Creative writing — blog posts, descriptions, copy - Summarization — long documents, transcripts - Structured output — tables, outlines, formatted docs --- ## ❤️ OPUS — Complex Reasoning Only **Escalate to Opus for:** ### Architecture & Design - System architecture decisions - Major codebase refactoring - Design pattern selection with tradeoffs - Database schema design ### Deep Analysis - Complex debugging (multi-file, race conditions) - Security reviews - Performance optimization strategy - Root cause analysis of subtle bugs ### Strategic & Creative - Strategic planning — business decisions, roadmaps - Nuanced judgment — ethics, ambiguity, competing values - Deep research — comprehensive multi-source analysis --- ## 🔄 Implementation ### For Subagents \`\`\`javascript // Routine monitoring sessions_spawn(task="Check backup status", model="haiku") // Standard code work sessions_spawn(task="Build the REST API endpoint", model="sonnet") // Architecture decisions sessions_spawn(task="Design the database schema for multi-tenancy", model="opus") \`\`\` ### For Cron Jobs \`\`\`json { "payload": { "kind": "agentTurn", "model": "haiku" } } \`\`\` Always use Haiku for cron unless the task genuinely needs reasoning. --- ## 📊 Quick Decision Tree \`\`\` Is it a greeting, lookup, status check, or 1-2 sentence answer? YES → HAIKU NO ↓ Is it code, analysis, planning, writing, or multi-step? YES → SONNET NO ↓ Is it architecture, deep reasoning, or critical decision? YES → OPUS NO → Default to SONNET, escalate if struggling \`\`\` --- ## 📋 Quick Reference Card \`\`\` ┌─────────────────────────────────────────────────────────────┐ │ SMART MODEL SWITCHING │ │ Haiku → Sonnet → Opus │ ├─────────────────────────────────────────────────────────────┤ │ 💚 HAIKU (cheapest) │ │ • Greetings, status checks, quick lookups │ │ • Factual Q&A, definitions, reminders │ │ • Simple file ops, 1-2 sentence answers │ ├─────────────────────────────────────────────────────────────┤ │ 💛 SONNET (standard) │ │ • Code > 10 lines, debugging │ │ • Analysis, comparisons, planning │ │ • Reports, proposals, long writing │ ├─────────────────────────────────────────────────────────────┤ │ ❤️ OPUS (complex) │ │ • Architecture decisions │ │ • Complex debugging, multi-file refactoring │ │ • Strategic planning, deep research │ ├─────────────────────────────────────────────────────────────┤ │ 💡 RULE: If a human needs > 30 sec thinking → escalate │ │ 💰 COST: Haiku 1x → Sonnet 12x → Opus 60x │ └─────────────────────────────────────────────────────────────┘ \`\`\` --- *Built for Claude-only setups with Haiku, Sonnet, and Opus.* *Inspired by save-money skill, extended with three-tier progression.*
