dev-lead-routing
Routes development tasks to the correct language or framework expert agent. Use when user requests code review, implementation, refactoring, or debugging.
SKILL.md.claude/skills/dev-lead-routing/SKILL.md
GitHubMandatory delegation directive (R010 Universal /tmp Script Bypass)
When this skill spawns a subagent via the Agent tool, the spawned prompt MUST include this directive verbatim (or equivalent):
ALL tool calls targeting
.claude/paths MUST go through/tmp/*.shscript via Bash. This includes read-only measurement (sed/cat/wc/ls/grep), Write, Edit. Read tool is exempt. Direct Write/Edit/Bash on .claude/ triggers user approval prompts that block unattended automation. See R010 for the full pattern.
This directive is preserved inline because Agent-tool prompt synthesis can drop SKILL.md notes; inline mandatory directives survive (#1046 lesson).

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:
- Check
/tmp/.claude-env-status-*for codex, gemini, and rtk availability - If codex available AND task involves new file creation → automatically delegate to
/codex-execfor 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)
- Display:
- If codex unavailable but gemini available → delegate to
/gemini-execfor scaffolding:- Display:
[Gemini Hybrid] Delegating to gemini-exec... - gemini-exec generates initial code
- Selected Claude expert reviews and refines output
- Display:
- If RTK available (
RTK=availablein 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
- Display:
- If none available → display
[External CLI] Unavailable — proceeding with {expert} directlyand 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 via Agent tool, always pass
mode: "bypassPermissions". The Agent tool default (acceptEdits) overrides agent frontmatterpermissionMode, causing permission prompts during unattended execution.
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 4b: Wiki-RAG Enrichment
For ambiguous routing (confidence < 90%), query the wiki for context:
- Search
wiki/index.yamlfor agent/skill pages matching detected keywords - If wiki suggests a specific skill or guide for the task, inject as
suggested_contextin the agent prompt - This helps agents receive relevant guide references automatically
wiki-rag query: "{user_request}" → wiki agent/skill pages → suggested_context injection
Advisory only — skip silently if wiki unavailable.
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.
