Security: API Key Handling

CRITICAL: Read comprehensive security rules:

@docs/security/SECURITY-RULES.md

Never hardcode API keys, passwords, or secrets in any generated files.

When generating configuration or code:

❌ NEVER use real API keys or credentials
✅ ALWAYS use placeholders: your_service_key_here
✅ Format: {project}_{env}_your_key_here for multi-environment
✅ Read from environment variables in code
✅ Add .env* to .gitignore (except .env.example)
✅ Document how to obtain real keys

Security Requirements

CRITICAL: All generated files must follow security rules:

@docs/security/SECURITY-RULES.md

Key requirements:

Never hardcode API keys or secrets
Use placeholders: your_service_key_here
Protect .env files with .gitignore
Create .env.example with placeholders only
Document key acquisition for users

Input Parameters

You will receive:

project_name: Project name from directory or package.json
project_platform: Detected platform (Next.js, React, Python, FastAPI, etc.)
monitoring_platform: Selected platform (sentry, datadog, etc.)
sentry_org_slug: Organization slug (if Sentry)
sentry_project_slug: Project slug (if Sentry)
sentry_dsn: DSN from MCP (if Sentry)

Task: Execute Monitoring Setup

Step 1: Install Dependencies

Install based on platform and language:

For Sentry + Node.js:

npm install --save @sentry/node @sentry/profiling-node

For Sentry + Next.js:

npm install --save @sentry/nextjs

For Sentry + Python:

pip install sentry-sdk

For DataDog + Node.js:

npm install --save dd-trace

For DataDog + Python:

pip install ddtrace

Report installation status with package versions

Step 2: Configure Doppler Storage

Store DSN/API keys in Doppler (never commit to git):

Check if Doppler is installed:

which doppler && echo "installed" || echo "not-installed"

If not installed, return instructions but do not auto-install

For Sentry, store credentials:

doppler secrets set SENTRY_DSN="<dsn>" --config dev
doppler secrets set SENTRY_ORG_SLUG="<org_slug>" --config dev
doppler secrets set SENTRY_PROJECT_SLUG="<project_slug>" --config dev

For DataDog, store credentials:

doppler secrets set DD_API_KEY="<placeholder>" --config dev
doppler secrets set DD_APP_KEY="<placeholder>" --config dev

Create .env.example with placeholders only:

SENTRY_DSN=your_sentry_dsn_here
SENTRY_ENVIRONMENT=development
SENTRY_ORG_SLUG=your-org-slug
SENTRY_PROJECT_SLUG=your-project-slug

Ensure .env in .gitignore:

grep -q "^.env$" .gitignore || echo ".env" >> .gitignore

Step 3: Integrate into Application

Detect entry point:

ls -1 index.js server.js app.js main.py app.py 2>/dev/null | head -1

For Sentry + Node.js/Next.js, add initialization:

import * as Sentry from "@sentry/node";

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  environment: process.env.SENTRY_ENVIRONMENT || "development",
  tracesSampleRate: 1.0,
});

For Sentry + Python, add initialization:

import sentry_sdk

sentry_sdk.init(
    dsn=os.getenv("SENTRY_DSN"),
    environment=os.getenv("SENTRY_ENVIRONMENT", "development"),
    traces_sample_rate=1.0,
)

For Next.js, create sentry.client.config.js and sentry.server.config.js

Create error handler middleware if applicable

Step 4: Install and Configure Sentry CLI

Check if sentry-cli installed:

which sentry-cli || echo "not-installed"

If not installed:

npm install -g @sentry/cli

Verify installation:

sentry-cli --version

Create .sentryclirc with environment variable references (never hardcoded):

[auth]
token=${SENTRY_AUTH_TOKEN}

[defaults]
org=${SENTRY_ORG_SLUG}
project=${SENTRY_PROJECT_SLUG}

Add .sentryclirc to .gitignore:

grep -q "^.sentryclirc$" .gitignore || echo ".sentryclirc" >> .gitignore

Store auth token in Doppler:

doppler secrets set SENTRY_AUTH_TOKEN="<placeholder>" --config dev

Step 5: Configure Alert Rules

Create monitoring-alerts.yml with basic alert rules:

alerts:
  - name: High Error Rate
    condition: error_count > 100 per hour
    severity: high

  - name: Slow Response Time
    condition: avg_response_time > 5s
    severity: medium

  - name: Low Availability
    condition: uptime < 99.9%
    severity: critical

Document alert configuration in platform dashboard

Provide webhook setup guide for Slack/Discord/PagerDuty

Step 6: CI/CD Integration

Check for GitHub Actions workflows:

ls -1 .github/workflows/*.yml 2>/dev/null

Add Sentry release tracking to CI/CD workflow:

- name: Create Sentry Release
  env:
    SENTRY_AUTH_TOKEN: ${{ secrets.SENTRY_AUTH_TOKEN }}
    SENTRY_ORG: ${{ secrets.SENTRY_ORG_SLUG }}
    SENTRY_PROJECT: ${{ secrets.SENTRY_PROJECT_SLUG }}
  run: |
    VERSION=$(cat VERSION | jq -r '.version')
    sentry-cli releases new $VERSION
    sentry-cli releases set-commits $VERSION --auto
    sentry-cli releases files $VERSION upload-sourcemaps ./dist
    sentry-cli releases finalize $VERSION
    sentry-cli releases deploys $VERSION new -e production

Add post-deploy health check step

Return list of required CI/CD secrets

Output Format

Return a JSON object:

{
  "status": "success|error",
  "platform": "sentry|datadog",
  "dependencies_installed": ["@sentry/node", "@sentry/profiling-node"],
  "doppler_configured": true|false,
  "doppler_secrets": ["SENTRY_DSN", "SENTRY_ORG_SLUG", "SENTRY_PROJECT_SLUG"],
  "integration_files_modified": ["index.js", "sentry.client.config.js"],
  "sentry_cli_installed": true|false,
  "cicd_integration_added": true|false,
  "cicd_secrets_required": ["SENTRY_AUTH_TOKEN", "SENTRY_ORG_SLUG", "SENTRY_PROJECT_SLUG"],
  "alert_config_created": true|false,
  "env_example_created": true|false,
  "gitignore_updated": true|false,
  "error": "error message if status is error"
}

Error Handling

Handle failures gracefully:

Dependency installation fails → Return error with details
Doppler not installed → Return instructions without failing
File modification fails → Return error with file path
CLI installation fails → Return error with troubleshooting steps

Return error status with clear message and suggested fixes for each error type.

Important Notes

Never hardcode credentials - always use environment variables
Store secrets in Doppler, not in .env files
Create .env.example with placeholders only
Update .gitignore to protect secrets
Provide clear instructions for manual steps (API token generation, etc.)
