What is Dev-Crew?

Dev-Crew gives you an entire AI development team from your terminal. Instead of one generic AI assistant, you get 24 specialized agents — each an expert in their domain: code review, security auditing, DevOps, database design, mobile development, and more.

npm install -g dev-crew

$ dev-crew doctor

Quality & Performance

Interactive Mode

Start a REPL session and talk to your agents using natural language:

dev-crew interactive   # or: dev-crew i

  ____              _____
 |  _ \  _____   __/ ____|_ __ _____      __
 | | | |/ _ \ \ / / |   | '__/ _ \ \ /\ / /
 | |_| |  __/\ V /| |___| | |  __/\ V  V /
 |____/ \___| \_/  \_____|_|  \___| \_/\_/

  Interactive Mode — type a command or ask a question
  Type /help for available commands, /quit to exit

  Project: my-app (typescript / nestjs)
  Provider: Claude Code (available)

❯ review src/controllers/
❯ fix the authentication bug
❯ write tests for the user service
❯ explain how the middleware works
❯ check security of the API routes
❯ is there any technical debt?

Slash Commands

All Commands

Multi-Provider Support

Dev-Crew auto-detects and works with multiple AI backends:

Dev-Crew auto-selects the best available provider. If none are installed, simulation mode activates automatically — returning realistic mock responses so you can explore every command without an AI backend.

# Check which providers are available
dev-crew doctor

# In interactive mode
❯ /providers

Key Features

Smart Context Engine

Automatically gathers relevant files, schemas, configs, and dependency graphs — then compresses them to save 40-70% tokens.

Project Auto-Detection

Detects your language, framework, database, ORM, test runner, package manager, CI platform, and project structure on first run.

Feedback System

Teach agents your preferences. Feedback persists across sessions:

dev-crew feedback review "Always flag any use of 'any' type in TypeScript"
dev-crew feedback security "We use Helmet.js for HTTP headers, don't flag those"

Token Intelligence

Track usage, set budgets, and estimate costs before running commands:

dev-crew tokens estimate src/
dev-crew tokens usage

CI/CD Integration

# GitHub Actions
- name: Dev-Crew Review
  run: npx dev-crew review src/ --ci
  # Exit code 2 = critical issues found

Feature Pipeline

Run multiple agents in sequence on a single feature:

dev-crew feature "Add JWT authentication with refresh tokens"
# Runs: BA -> Tech Lead -> Security -> Test -> Review

Configuration

Dev-Crew stores config in .dev-crew/config.yml:

project:
  name: my-app
  stack: nestjs
  database: postgresql
  orm: prisma
  test_framework: vitest

settings:
  max_tokens_per_request: 8000
  show_token_usage: true
  auto_include_schema: true
  confirm_before_apply: true

agents:
  review:
    severity: normal
    rules:
      - "Always check for SQL injection in raw queries"
      - "Enforce strict TypeScript — no 'any' types"
    ignore:
      - "**/*.spec.ts"
      - "src/generated/**"
    focus:
      - security
      - performance
      - error-handling
  test:
    framework: vitest
    coverage_target: 80
