# Send Smart Model Switching to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "smart-model-switching", "name": "Smart Model Switching", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/millibus/smart-model-switching", "canonicalUrl": "https://clawhub.ai/millibus/smart-model-switching", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/smart-model-switching", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=smart-model-switching", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-07T17:22:31.273Z", "expiresAt": "2026-05-14T17:22:31.273Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=afrexai-annual-report", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=afrexai-annual-report", "contentDisposition": "attachment; filename=\"afrexai-annual-report-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null }, "scope": "source", "summary": "Source download looks usable.", "detail": "Yavira can redirect you to the upstream package for this source.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/smart-model-switching" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/smart-model-switching", "downloadUrl": "https://openagent3.xyz/downloads/smart-model-switching", "agentUrl": "https://openagent3.xyz/skills/smart-model-switching/agent", "manifestUrl": "https://openagent3.xyz/skills/smart-model-switching/agent.json", "briefUrl": "https://openagent3.xyz/skills/smart-model-switching/agent.md" } } ``` ## Documentation ### 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 ModelInputOutputRelative CostHaiku$0.25/M$1.25/M1x (baseline)Sonnet$3.00/M$15.00/M12xOpus$15.00/M$75.00/M60x 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 ### 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.
