  Use this skill when analyzing a prompt or task to determine the optimal Claude model
  (haiku, sonnet, or opus). Triggers when needing to route tasks, select models for
  subagents, or optimize cost/quality tradeoffs.

Model Selection Criteria

Analyze the task and select the optimal model using these criteria.

Model Tiers

Haiku - Fast & Efficient

Select haiku when the task involves:

  • •Simple lookups or searches
  • •Pattern matching across files
  • •Scanning for specific strings/patterns
  • •Quick questions with factual answers
  • •Listing files, directories, or contents
  • •Basic formatting or transformation
  • •Summarizing without deep analysis
  • •Validation checks (syntax, schema)

Indicators in prompt:

  • •"find", "search", "list", "scan", "check"
  • •"what is", "where is", "show me"
  • •Short, direct questions
  • •File/directory operations
  • •Simple transformations

Sonnet - Balanced & Capable

Select sonnet when the task involves:

  • •Writing or modifying code
  • •Implementation of features
  • •Bug investigation and fixing
  • •Nuanced reasoning about tradeoffs
  • •Code review and analysis
  • •Test writing
  • •Documentation with context
  • •Multi-step reasoning
  • •Refactoring existing code

Indicators in prompt:

  • •"implement", "create", "build", "write"
  • •"fix", "debug", "investigate"
  • •"refactor", "improve", "optimize"
  • •"review", "analyze"
  • •Code snippets or file references
  • •Feature descriptions

Opus - Deep & Complex

Select opus when the task involves:

  • •Architectural design decisions
  • •Complex system design
  • •Novel algorithm development
  • •Deep analysis requiring creativity
  • •Strategic planning
  • •Decisions with significant tradeoffs
  • •Problems requiring multiple expert perspectives
  • •Tasks where correctness is critical and complex

Indicators in prompt:

  • •"design", "architect", "plan"
  • •"complex", "tradeoffs", "strategy"
  • •"novel", "creative", "innovative"
  • •System-wide implications
  • •Abstract reasoning required
  • •Multiple interacting components

Decision Algorithm

  1. •Check for opus indicators first - If task involves architecture, design, or complex reasoning → opus
  2. •Check for haiku indicators - If task is simple lookup, scan, or factual → haiku
  3. •Default to sonnet - Most coding tasks benefit from sonnet's balance

Cost-Quality Tradeoff

ModelSpeedCostQuality
Haiku★★★★★★★★★★★★★
Sonnet★★★★★★★★★★
Opus★★★★★★★★

When in doubt: Prefer sonnet. It handles most tasks well and the cost/quality tradeoff is optimal for general development work.

Output Format

After analysis, report:

code
✨ <Model> - <Brief reason>

Examples:

  • •✨ Haiku - Simple file search task
  • •✨ Sonnet - Code implementation with moderate complexity
  • •✨ Opus - Complex architectural design requiring deep analysis
