Smart Model Switching

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.

  • Confirm the extracted package contains the expected setup assets.

Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

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

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.

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
