Model Selection

Task	Model
Architecture analysis	opus
Code review/implementation	sonnet
Quick validation/search	haiku

Routing Decision (Priority Order)

Before selecting an expert agent, evaluate in this order:

Step 1: Agent Teams Eligibility (R018)

Check if Agent Teams is available (CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 or TeamCreate/SendMessage tools present).

Scenario	Preferred
Single-language review	Task Tool
Multi-language code review (3+)	Agent Teams
Code review + fix cycle	Agent Teams
Cross-layer debugging (FE + BE + DB)	Agent Teams
Simple file search/validation	Task Tool

Step 2: Codex-Exec Hybrid (Implementation Tasks)

For new file creation, boilerplate, or test code generation:

1. Check /tmp/.claude-env-status-* for codex, gemini, and rtk availability
2. If codex available AND task involves new file creation → automatically delegate to /codex-exec for scaffolding:
   • Display: [Codex Hybrid] Delegating to codex-exec...
   • codex-exec generates initial code (strength: fast generation)
   • Selected Claude expert reviews and refines codex output (strength: reasoning, quality)
3. If codex unavailable but gemini available → delegate to /gemini-exec for scaffolding:
   • Display: [Gemini Hybrid] Delegating to gemini-exec...
   • gemini-exec generates initial code
   • Selected Claude expert reviews and refines output
4. If RTK available (RTK=available in env status) → optionally wrap Claude expert output through RTK to reduce token consumption by 60-90%:
   • Display: [RTK Proxy] Token optimization active via rtk-exec
   • RTK acts as a transparent proxy — no change to expert selection
5. If none available → display [External CLI] Unavailable — proceeding with {expert} directly and use Claude expert directly

Suitable: New file creation, boilerplate, scaffolding, test code Unsuitable: Existing code modification, architecture decisions, bug fixes

Step 3: Expert Agent Selection

Route to appropriate language/framework expert based on file extension and keyword mapping.

Permission Mode: When spawning agents, pass mode: "bypassPermissions" in the Agent tool call if the session uses bypassPermissions. Without explicit mode, CC defaults to acceptEdits.

Step 4: Ontology-RAG Enrichment (R019)

If get_agent_for_task MCP tool is available, call it with the original query and inject suggested_skills into the agent prompt. Skip silently on failure.

Step 5: Soul Injection (R006)

If the selected agent has soul: true in frontmatter, read and prepend .claude/agents/souls/{agent-name}.soul.md content to the prompt. Skip silently if file doesn't exist.

Routing Rules

Multi-language: detect all languages, route to parallel experts (max 4). Single-language: route to matching expert. Cross-layer (frontend + backend): multiple experts in parallel.

No Match Fallback

When file extension or keyword doesn't match any existing agent:

User Input → No matching development agent
  ↓
Detect: File extension (.rb, .swift, .php, etc.) or language keyword
  ↓
Delegate to mgr-creator with context:
  domain: detected language/framework
  type: sw-engineer
  keywords: extracted from user input
  file_patterns: detected extensions
  skills: auto-discover from .claude/skills/
  guides: auto-discover from templates/guides/

Examples of dynamic creation triggers:

• Unrecognized file extension (e.g., .rb → Ruby expert, .swift → Swift expert)
• New framework keyword (e.g., "Flutter 앱 리뷰해줘", "Rails API 만들어줘")
• Language detected but no specialist exists

Not user-invocable. Auto-triggered on development intent.
