# Dev Lead Routing > Routes development tasks to the correct language or framework expert agent. Use when user requests code review, implementation, refactoring, or debugging. Use when this capability is needed. - Skill: `tomevault-io/dev-lead-routing` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/dev-lead-routing` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/dev-lead-routing/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/dev-lead-routing --- # Dev Lead Routing ## Engineers | Type | Agents | |------|--------| | Language | lang-golang-expert, lang-python-expert, lang-rust-expert, lang-kotlin-expert, lang-typescript-expert, lang-java21-expert | | Frontend | fe-vercel-agent, fe-vuejs-agent, fe-svelte-agent, fe-flutter-agent, fe-design-expert | | Backend | be-fastapi-expert, be-springboot-expert, be-go-backend-expert, be-nestjs-expert, be-express-expert, be-django-expert | | Tooling | tool-npm-expert, tool-optimizer, tool-bun-expert | | Database | db-supabase-expert, db-postgres-expert, db-redis-expert, db-alembic-expert | | Architect | arch-documenter, arch-speckit-agent | | Security | sec-codeql-expert | | Infra | infra-docker-expert, infra-aws-expert | ## File Extension Mapping | Extension | Agent | |-----------|-------| | `.go` | lang-golang-expert | | `.py` | lang-python-expert | | `.rs` | lang-rust-expert | | `.kt`, `.kts` | lang-kotlin-expert | | `.ts`, `.tsx` | lang-typescript-expert | | `.java` | lang-java21-expert | | `.js/.jsx` (React) | fe-vercel-agent | | `.vue` | fe-vuejs-agent | | `.svelte` | fe-svelte-agent | | `.dart`, `pubspec.yaml` | fe-flutter-agent | | `.sql` (PG) | db-postgres-expert | | `.sql` (Supabase) | db-supabase-expert | | `alembic.ini`, `alembic/versions/*.py` | db-alembic-expert | | `Dockerfile`, `*.dockerfile` | infra-docker-expert | | `*.tf`, `*.tfvars` | infra-aws-expert | | `*.yaml`, `*.yml` (CloudFormation) | infra-aws-expert | ## Keyword Mapping | Keywords | Agent | |----------|-------| | go, golang | lang-golang-expert | | python, py | lang-python-expert | | rust | lang-rust-expert | | kotlin | lang-kotlin-expert | | typescript, ts | lang-typescript-expert | | java | lang-java21-expert | | react, next.js, vercel | fe-vercel-agent | | vue | fe-vuejs-agent | | svelte | fe-svelte-agent | | flutter, dart, riverpod, bloc, widget | fe-flutter-agent | | design, typography, color, motion, ux writing, ui design, "design system", "design review", impeccable | fe-design-expert | | fastapi | be-fastapi-expert | | django | be-django-expert | | spring, springboot | be-springboot-expert | | nestjs | be-nestjs-expert | | express | be-express-expert | | npm | tool-npm-expert | | optimize, bundle | tool-optimizer | | bun | tool-bun-expert | | postgres, postgresql, psql, pg_stat | db-postgres-expert | | redis, cache, pub/sub, sorted set | db-redis-expert | | supabase, rls, edge function | db-supabase-expert | | alembic, migration, db revision, db upgrade, db downgrade | db-alembic-expert | | docker, dockerfile, container, compose | infra-docker-expert | | aws, cloudformation, vpc, iam, s3, lambda, cdk, terraform | infra-aws-expert | | security, codeql, cve, vulnerability, sarif, sast, security audit | sec-codeql-expert | | architecture, adr, openapi, swagger, diagram | arch-documenter | | spec, specification, tdd, requirements | arch-speckit-agent | ## 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. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/baekenough) — claim your Tome and manage your conversions.
