Build Router

Build Router (Unified)

Tier: unified Absorbs: development-router + infrastructure-router + documentation-router Purpose: All creation/building tasks (code, configs, docs)

Triggers

patterns:
  - build, implement, create, develop
  - frontend, backend, fullstack, API
  - mcp, server, hook, deploy
  - document, readme, explain, changelog
  - terminal, TUI, CLI interface

Build Domains

Frontend Development

triggers: [UI, UX, component, styling, React, Vue, Svelte]
agent: frontend-engineer
skills:
  - frontend-ui-ux (active)
  - component patterns
  - accessibility (WCAG)
  - responsive design

Backend Development

triggers: [API, server, database, authentication]
patterns:
  - RESTful API design
  - GraphQL schemas
  - Database modeling
  - Authentication/authorization

Infrastructure

triggers: [MCP, hook, config, deploy, tooling]
skills:
  - mcp-builder (db/skill-db)
  - hook development
  - configuration management
workflows:
  - MCP server: Research → Implement → Review → Evaluate

Documentation

triggers: [document, readme, explain, changelog, API docs]
agent: document-writer
patterns:
  - README creation
  - API documentation
  - Code comments
  - Changelogs

Workflow Integration

standard_flow:
  1. Analyze requirements
  2. Plan implementation
  3. Build incrementally
  4. Test and validate
  5. Document

sc_commands:
  - sc:implement → Guided implementation
  - sc:build → Build workflow
  - sc:document → Documentation

Build Tool Detection

package_managers:
  package.json: pnpm | npm | yarn | bun
  pyproject.toml: uv | poetry | pip
  Cargo.toml: cargo
  go.mod: go

build_commands:
  typescript: "pnpm build" | "npm run build" | "bun build"
  python: "uv run python -m build" | "poetry build"
  rust: "cargo build --release"

test_runners:
  typescript: vitest | jest | playwright
  python: pytest
  rust: cargo test

linting:
  typescript: eslint | prettier | biome
  python: ruff | black | mypy
