Dev Lead Routing

Sensitive-Path Delegation

Sensitive-path compatibility note: if this skill delegates work that touches .claude/**, .claude/outputs/**, templates/.claude/**, or read-only measurements of those paths, keep .codex/** edits on the normal Codex path. On Claude Code v2.1.121+ with bypassPermissions, direct writes to .claude/skills/, .claude/agents/, and .claude/commands/ are allowed; on v2.1.126+ that extends to broader protected paths. Only use /tmp/{skill}-{timestamp}.md as a legacy fallback when the target runtime is older or still prompts.

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 (OMCODEX_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: External Interop Guidance (Implementation Tasks)

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

1. Use the selected expert agent as the default implementation path.
2. If the native Claude Code plugin openai/codex-plugin-cc is explicitly installed and requested, it may provide Codex interop for scaffolding before expert review.
3. If RTK is available (RTK=available in env status), optionally wrap expert output through rtk-exec 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
4. Otherwise display [External CLI] Not requested — proceeding with {expert} directly and use the expert directly.

Suitable for optional plugin interop: 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.

Claude compatibility Agent calls only (R010 “Delegated Permission Ownership”): Pass mode: "bypassPermissions" when the active Claude session uses bypass permissions. Native Codex spawn_agent has no mode parameter; use the installed agent_type and active Codex runtime permissions instead.

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 .codex/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 .codex/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.
