Tech Stack Detector Skill

This skill provides intelligent detection of technologies, frameworks, and tools used in a project.

Detection Matrix

Languages

Language Detection Files Indicators
TypeScript tsconfig.json, *.ts, *.tsx "typescript" in deps
JavaScript *.js, *.jsx, jsconfig.json No tsconfig
Python pyproject.toml, setup.py, *.py python, pip, poetry
Go go.mod, go.sum, *.go module declaration
Rust Cargo.toml, *.rs [package] section
Java pom.xml, build.gradle, *.java Maven/Gradle markers
C# *.csproj, *.sln MSBuild configs
Ruby Gemfile, *.rb gem declarations
PHP composer.json, *.php "require" section

Frontend Frameworks

Framework Detection Key Indicators
React react in deps JSX files, hooks patterns
Vue vue in deps .vue files, Options/Composition API
Angular @angular/core *.component.ts, decorators
Svelte svelte in deps .svelte files
Next.js next in deps pages/ or app/ directory
Nuxt nuxt in deps nuxt.config.*
Remix @remix-run/* app/routes/ structure
Astro astro in deps .astro files

Backend Frameworks

Framework Detection Key Indicators
Express express in deps app.use(), route handlers
Fastify fastify in deps Plugin architecture
NestJS @nestjs/core Decorators, modules
Django django in requirements settings.py, urls.py
FastAPI fastapi in requirements @app.get() decorators
Flask flask in requirements @app.route()
Spring spring-boot in pom @RestController
Rails rails in Gemfile MVC structure
Laravel laravel/framework artisan, routes/web.php

Desktop Frameworks

Framework Detection Key Indicators
Electron electron in deps main.js, preload.js
Tauri @tauri-apps/* tauri.conf.json
Qt CMakeLists.txt + Qt #include <Qt*>

Build Tools

Tool Detection File Config Pattern
Vite vite.config.* defineConfig()
Webpack webpack.config.* module.exports = {}
Rollup rollup.config.* export default {}
esbuild esbuild.config.* build() calls
Turbo turbo.json pipeline config
Nx nx.json projects, generators
Parcel package.json "source" No config file needed
SWC .swcrc jsc config

Package Managers

Manager Detection File Lock File
npm package.json package-lock.json
yarn package.json yarn.lock
pnpm package.json pnpm-lock.yaml
bun package.json bun.lockb
pip requirements.txt -
poetry pyproject.toml poetry.lock
cargo Cargo.toml Cargo.lock
maven pom.xml -
gradle build.gradle gradle.lockfile

Testing Frameworks

Framework Detection Config File
Jest jest in deps jest.config.*
Vitest vitest in deps vitest.config.*
Mocha mocha in deps .mocharc.*
Cypress cypress in deps cypress.config.*
Playwright @playwright/test playwright.config.*
Pytest pytest in requirements pytest.ini, pyproject.toml
JUnit pom.xml + junit -
RSpec rspec in Gemfile .rspec

Databases

Database Detection Connection Patterns
PostgreSQL pg, psycopg2 postgres://, postgresql://
MySQL mysql2, mysqlclient mysql://
MongoDB mongodb, mongoose mongodb://
Redis redis, ioredis redis://
SQLite sqlite3, better-sqlite3 .db, .sqlite files
Prisma @prisma/client schema.prisma
Drizzle drizzle-orm drizzle.config.ts

Cloud & Infrastructure

Service Detection Config
AWS @aws-sdk/* .aws/, serverless.yml
GCP @google-cloud/* gcloud references
Azure @azure/* azure-pipelines.yml
Vercel vercel in deps vercel.json
Docker Dockerfile docker-compose.yml
Kubernetes k8s manifests *.yaml with apiVersion
Terraform *.tf files main.tf, variables.tf

Detection Algorithm

async function detectTechStack(projectRoot: string): Promise<TechStack> {
  const detections: Detection[] = [];

  // Phase 1: File-based detection (fast)
  const files = await glob(['package.json', 'tsconfig.json', '*.config.*', ...]);
  for (const file of files) {
    detections.push(...detectFromFile(file));
  }

  // Phase 2: Content-based detection (selective)
  const sampleFiles = selectRepresentativeFiles(projectRoot);
  for (const file of sampleFiles) {
    detections.push(...detectFromContent(file));
  }

  // Phase 3: Confidence scoring
  const stack = aggregateDetections(detections);
  return rankByConfidence(stack);
}

Output Format

## Tech Stack Analysis

### Primary Technologies
| Technology | Version | Confidence | Evidence |
|------------|---------|------------|----------|
| TypeScript | 5.3.x | HIGH | tsconfig.json, *.ts files |
| React | 18.x | HIGH | package.json, JSX patterns |
| Next.js | 14.x | HIGH | next.config.js, app/ directory |

### Build & Development
| Tool | Version | Purpose |
|------|---------|---------|
| pnpm | 8.x | Package manager |
| Turbo | 1.x | Monorepo build |
| Vite | 5.x | Dev server, bundling |

### Testing
| Framework | Coverage | Purpose |
|-----------|----------|---------|
| Jest | HIGH | Unit tests |
| Playwright | MEDIUM | E2E tests |

### Infrastructure
| Service | Purpose |
|---------|---------|
| Docker | Containerization |
| Vercel | Deployment |

### Uncertain Detections
⚠️ Redis: Found redis dependency but no connection config
⚠️ GraphQL: Found @apollo/client but no schema files

Integration with Steering

When invoked during /steering:

  1. Phase 2 (Tech Discovery) automatically uses this skill
  2. Populates tech.md with detected stack
  3. Generates accurate build commands
  4. Identifies environment variable requirements
  5. Detects testing framework for test commands

Confidence Levels

HIGH:   Config file + code evidence + dependencies
MEDIUM: Config file + dependencies (no code evidence)
LOW:    Dependencies only (may be unused)
