Devops Analyze

DevOps Analysis & Guided Questions

Overview

Reads project sources, detects the tech stack, then asks 6 guided questions with smart defaults. Produces devops/report/analysis.json consumed by all downstream sub-skills.

Step 1: Determine Scenario

Scan the working directory to determine which scenario applies:

Source code signals: .py, .ts, .tsx, .js, .mjs, .go, .java, .rb, .rs, .cs files outside of docs/.

If devops/report/analysis.json already exists and contains a scenario field, use that value without re-deriving.

Step 2: What to Read Per Scenario

Step 3: Stack Detection Rules

Apply these when reading source files:

Language detection (by file extension):

• .py → Python
• .ts or .tsx → TypeScript
• .js or .mjs → JavaScript
• .go → Go
• .java → Java
• .rb → Ruby
• .rs → Rust
• .cs → C#

Framework detection (by imports/dependencies):

• express or fastify → Node.js web
• react or next → React/Next.js
• fastapi or django or flask → Python web
• gin or echo or fiber → Go web
• spring → Java Spring
• rails → Ruby on Rails

Database detection (by ORM/driver imports or compose services):

For prisma: read prisma/schema.prisma and look for provider = "postgresql" → PostgreSQL, provider = "mysql" → MySQL. If not found, default to PostgreSQL.

For sequelize or typeorm: look for database URL patterns in .env.example or config files (postgresql:// → PostgreSQL, mysql:// → MySQL). Default to PostgreSQL if not found.

For sqlalchemy or django.db: look for DATABASE_URL in .env.example or settings.py (postgresql:// → PostgreSQL, mysql:// → MySQL). Default to PostgreSQL if not found.

For mongoose: MongoDB.

For redis package import: Redis.

Cloud detection (by SDK imports):

• boto3, @aws-sdk → AWS
• google-cloud, @google-cloud → GCP
• @azure → Azure

CI/CD detection (by directory/file presence):

• .github/workflows/ → GitHub Actions
• .gitlab-ci.yml → GitLab CI
• .circleci/ → CircleCI

Container/K8s detection:

• Dockerfile present → set has_dockerfile: true
• k8s/ or kubernetes/ directory → set has_k8s_manifests: true
• docker-compose.yml or docker-compose*.yml present → set has_existing_compose: true
• devops/ directory exists with at least one config file inside → set has_existing_devops_folder: true

External services detection (by import names):

• stripe → Stripe
• twilio → Twilio
• sendgrid or @sendgrid → SendGrid
• mailgun → Mailgun
• sentry → Sentry
• datadog → Datadog

Project name resolution (in priority order):

1. package.json → name field
2. pyproject.toml → [project].name field
3. go.mod → last segment of the module path
4. pom.xml → <artifactId> field
5. *.gemspec → spec.name field
6. Fallback: current directory name

Step 4: Guided Questions

Ask these one at a time, in order. Show the detected default in [brackets]. Wait for the user's answer before asking the next question.

If the user says "skip", "unsure", "doesn't matter", or gives no clear answer: use the detected default. If no default was detected, use the first listed option as the fallback. Do not ask again. Exception: for Q5 (secrets management), if a cloud-provider-derived default exists from the mapping below, use that instead of the first listed option.

Q1: Cloud provider

"Cloud provider [detected: X | none detected]: AWS / GCP / Azure / Multi-cloud / Self-hosted"

Q2: CI/CD platform

"CI/CD platform [detected: X | none detected — GitHub Actions recommended if new]: GitHub Actions / GitLab CI / CircleCI"

Q3: Deployment target

"Deployment target [detected: X | none detected]: Containers (ECS/Cloud Run/ACA) / Kubernetes / Serverless (Lambda/Cloud Functions/Azure Functions) / VMs"

Q4: Database and stateful services

"Confirmed stateful services [detected: postgres, redis | none detected]: (confirm the list or add/remove services)"

Q5: Secrets management

First resolve the suggested default using this mapping: AWS → AWS Secrets Manager, GCP → GCP Secret Manager, Azure → Azure Key Vault, none → env files (.env.local gitignored).

Then ask:

"Secrets management [suggested: X]: AWS Secrets Manager / GCP Secret Manager / HashiCorp Vault / Azure Key Vault / env files (.env.local gitignored)"

Q6: Team size

"Team size (affects pipeline complexity): Solo (<5 devs) / Small team (5-20 devs, daily deploys) / Large team (20+ devs, CI on every PR)"

Step 5: Write Output

Create devops/report/ directory if it doesn't exist, then write devops/report/analysis.json:

{
  "scenario": "design | codebase | review",
  "project_name": "detected via resolution chain above",
  "stack": {
    "language": "TypeScript",
    "framework": "Express",
    "database": ["PostgreSQL", "Redis"],
    "external_services": ["Stripe"]
  },
  "choices": {
    "cloud_provider": "AWS",
    "ci_cd_platform": "GitHub Actions",
    "deployment_target": "Containers",
    "secrets_management": "AWS Secrets Manager",
    "team_size": "Small team"
  },
  "detected": {
    "has_dockerfile": false,
    "has_k8s_manifests": false,
    "has_existing_ci": false,
    "has_existing_compose": false,
    "has_existing_devops_folder": false,
    "existing_ci_platform": null
  }
}

Substitute all values from actual detection and user answers. Do not leave template placeholder values.

Set has_existing_ci: true and existing_ci_platform: "GitHub Actions" (or whichever was detected) when a CI config file was found.

Confirm to the user: "Analysis complete. Saved to devops/report/analysis.json."
