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_path: Path to project directory (default: current directory)

Task: Execute Pre-Flight Checks

Step 1: Detect Project Type

Check for indicator files:

ls -1 package.json requirements.txt pyproject.toml go.mod Cargo.toml .mcp.json 2>/dev/null

Identify project language and framework:

Node.js: package.json with dependencies
Python: requirements.txt or pyproject.toml
Go: go.mod
Rust: Cargo.toml
MCP Server: .mcp.json

Parse configuration files for context (if exist):

package.json: name, version, dependencies
requirements.txt: Python packages
.env.example: Required environment variables

Step 2: Platform Linkage Check

Detect target platform from project structure:

Vercel: next.config.js, vercel.json, or React/Vue in package.json
DigitalOcean: Dockerfile, app-spec.yml, or containerized app
Railway: railway.json or backend API project
Netlify: netlify.toml or static site
FastMCP Cloud: .mcp.json with FastMCP server

For Vercel projects:

[ -f ".vercel/project.json" ] && echo "✅ Linked" || echo "⚠️  Not linked"

If not linked, execute: vercel link --yes Verify linkage: cat .vercel/project.json | jq -r '.projectId'

For DigitalOcean projects:

[ -f "app-spec.yml" ] || [ -f ".do/app.yaml" ] && echo "✅ App spec exists" || echo "⚠️  No app spec"

If missing, note that spec needs creation

For Railway projects:

[ -f "railway.json" ] && echo "✅ Linked" || echo "⚠️  Not linked"

If not linked, note that linking is required

Step 3: Dependency Check

For Node.js projects (package.json):

[ -d "node_modules" ] && echo "✅ Installed" || echo "❌ Run npm install"
npm list --depth=0 2>&1 | head -20

For Python projects:

python3 --version
pip list | wc -l

For Go projects:

go version
go list -m all | head -10

Report missing dependencies with installation commands

Step 4: Build Tool Validation

Check platform-specific CLIs:

which fastmcp doctl vercel netlify railway 2>/dev/null

Check build tools:

which npm node python3 go cargo 2>/dev/null

Report missing tools with installation instructions:

FastMCP: pip install fastmcp
DigitalOcean: snap install doctl
Vercel: npm install -g vercel
Netlify: npm install -g netlify-cli
Railway: npm install -g @railway/cli

Step 5: Authentication Status

Check environment variables for credentials:

[ -n "$DIGITALOCEAN_ACCESS_TOKEN" ] && echo "✅ Set" || echo "⚠️  Not set"
[ -n "$VERCEL_TOKEN" ] && echo "✅ Set" || echo "⚠️  Not set"

Check CLI authentication status:

vercel whoami 2>/dev/null || echo "⚠️  Not authenticated"
netlify status 2>/dev/null || echo "⚠️  Not authenticated"
doctl auth list 2>/dev/null || echo "⚠️  Not authenticated"
railway whoami 2>/dev/null || echo "⚠️  Not authenticated"

Report authentication issues with login commands

Step 6: Environment Variables

Check for .env.example:

[ -f ".env.example" ] && cat .env.example || echo "No .env.example"

Extract required variables from .env.example (parse KEY=value format)

Check if .env file exists:

[ -f ".env" ] && echo "✅ Exists" || echo "⚠️  Missing"

Warn about missing critical variables

Verify .env is in .gitignore:

grep -q "^.env$" .gitignore && echo "✅ Protected" || echo "⚠️  Add to .gitignore"

Step 7: Git Status

Verify git repository:

git rev-parse --is-inside-work-tree 2>/dev/null && echo "✅ Git repo" || echo "⚠️  Not a git repository"

Check for uncommitted changes:

git status --porcelain | wc -l

Get current branch:

git branch --show-current

Check if branch is pushed to remote:

git rev-parse --abbrev-ref --symbolic-full-name @{u} 2>/dev/null

Step 8: CI/CD Configuration

Check for GitHub Actions workflow:

[ -f ".github/workflows/deploy.yml" ] && echo "✅ Exists" || echo "⚠️  Not found"

If workflow exists:

Display workflow path
Check for deployment-related jobs

If no workflow:

Note that automated deployments are not configured
Suggest: /deployment:setup-cicd

  ]
}

Error Handling

Handle edge cases gracefully:

Not a git repository → Note as issue but continue checks
Missing package managers → Report as critical issue
No platform detected → Suggest manual platform selection
Multiple possible platforms → List all detected platforms

Return comprehensive status even if some checks fail.

Important Notes

This agent performs read-only checks - no modifications
All issues are reported with clear resolution steps
Authentication checks are non-intrusive
Environment variable checks verify structure, not content
Git checks are informational only
