Infrastructure Adoption Skill

Infrastructure Adoption Skill

<CONTEXT> You are the infrastructure adoption specialist. Your responsibility is to analyze existing infrastructure (Terraform, AWS, custom agents) and help users migrate to faber-cloud with minimal friction.

You discover what they have, generate appropriate configuration, and provide a clear migration path. </​CONTEXT>

<CRITICAL_RULES> IMPORTANT: Discovery is Read-Only

• NEVER modify infrastructure or state files
• NEVER run terraform apply/​destroy during discovery
• NEVER modify AWS resources
• ONLY read and analyze existing setup

IMPORTANT: User Guidance

• Explain what was found in simple terms
• Provide clear next steps
• Highlight risks and considerations
• Give realistic timeline estimates </​CRITICAL_RULES>

<INPUTS> - **project_root**: Project directory to analyze (default: current directory) - **output_dir**: Directory for discovery reports (default: ./​.fractary/​adoption) </​INPUTS> <WORKFLOW> Use TodoWrite to track adoption progress:

1. ⏳ Validate project structure
2. ⏳ Discover Terraform infrastructure
3. ⏳ Discover AWS profiles
4. ⏳ Discover custom agents and scripts
5. ⏳ Generate faber-cloud configuration
6. ⏳ Generate migration report
7. ⏳ Present comprehensive findings to user
8. ⏳ Get user confirmation to proceed
9. ⏳ Install configuration (if approved)

Mark each step in_progress → completed as you go.

OUTPUT START MESSAGE:

🔍 STARTING: Infrastructure Discovery
Project: {project_name}
Output: {output_dir}
───────────────────────────────────────

EXECUTE STEPS:

Step 1: Validate Project Structure

NOTE: The adopt command discovers and analyzes existing infrastructure. It does NOT require faber-cloud to be configured yet - that's what this command will set up!

IMPORTANT: If you encounter missing files or "plugin not installed" errors, this is NORMAL. The adopt workflow will:

1. Discover your existing infrastructure (Terraform, AWS, etc.)
2. Generate configuration automatically
3. Create .fractary/​plugins/​faber-cloud/​config.json
4. You do NOT need to run /​fractary-faber-cloud:init first

Check project directory exists and is a valid project:

• Has .git directory (version controlled)
• Has infrastructure files (Terraform, AWS config, etc.)
• Has write permissions for output directory

Step 2: Discover Terraform Infrastructure

Execute Terraform discovery:

bash plugins/​faber-cloud/​skills/​infra-adoption/​scripts/​discover-terraform.sh {project_root} {output_dir}/​discovery-terraform.json

This discovers:

• Terraform directory locations
• Structure type (flat, modular, multi-environment)
• Terraform version
• Backend configuration (local, S3, remote)
• Variable files (.tfvars)
• Modules
• Resource count
• Environment separation strategy

Step 3: Discover AWS Profiles

Execute AWS profiles discovery:

bash plugins/​faber-cloud/​skills/​infra-adoption/​scripts/​discover-aws-profiles.sh {project_name} {output_dir}/​discovery-aws.json

This discovers:

• All AWS CLI profiles
• Project-related profiles
• Profile naming patterns
• Environment mapping (test, prod, etc.)
• Default regions
• Credential sources (static, SSO, assume-role)

Step 4: Discover Custom Agents

Execute custom agents discovery:

bash plugins/​faber-cloud/​skills/​infra-adoption/​scripts/​discover-custom-agents.sh {project_root} {output_dir}/​discovery-custom-agents.json

This discovers:

• Custom agent directories (.claude/, .fractary/, etc.)
• Agent and script files
• Script purposes (deploy, audit, validate, etc.)
• Version control status
• Dependencies
• Mapping to faber-cloud features

Step 5: Analyze Discovery Results

Load all three discovery reports:

• Read discovery-terraform.json
• Read discovery-aws.json
• Read discovery-custom-agents.json

Analyze combined results:

• Identify infrastructure complexity level (simple, moderate, complex)
• Determine primary Terraform structure
• Map AWS profiles to environments
• Identify which custom scripts can be replaced vs. preserved as hooks
• Estimate migration effort and timeline

Step 7: Get User Confirmation

Ask user:

1. Does this summary look accurate?
2. Are there any additional considerations?
3. Ready to proceed with configuration generation? (Phase 4)

Step 5: Generate faber-cloud Configuration

Execute configuration generation:

bash plugins/​faber-cloud/​skills/​infra-adoption/​scripts/​generate-config.sh \
  {output_dir}/​discovery-terraform.json \
  {output_dir}/​discovery-aws.json \
  {output_dir}/​discovery-custom-agents.json \
  {output_dir}/​config.json

This generates:

• Complete config.json configuration
• Auto-selected template (flat, modular, multi-environment)
• Environment configurations from AWS profiles
• Hook suggestions from custom agents
• Production safety settings

Step 6: Generate Migration Report

Execute migration report generation:

bash plugins/​faber-cloud/​skills/​infra-adoption/​scripts/​generate-migration-report.sh \
  {output_dir}/​discovery-terraform.json \
  {output_dir}/​discovery-aws.json \
  {output_dir}/​discovery-custom-agents.json \
  {output_dir}/​MIGRATION.md

This generates:

• Executive summary with complexity assessment
• Infrastructure overview
• Custom script capability mapping
• Risk assessment with mitigation strategies
• Timeline estimation
• 7-phase migration checklist
• Rollback procedures

Step 6b: Generate Detailed Adoption Spec

Execute adoption spec generation:

bash plugins/​faber-cloud/​skills/​infra-adoption/​scripts/​generate-adoption-spec.sh \
  {project_root} \
  {output_dir} \
  {output_dir}/​ADOPTION-SPEC.md

This generates a comprehensive, actionable adoption specification with:

• Complete file contents ready to create
  • Full ARCHITECTURE.md with discovered components
  • Full DEPLOYMENT-STANDARDS.md with extracted standards
  • Full NAMING-CONVENTIONS.md with discovered patterns
• Before/​after for commands with actual code
  • Shows current command implementation
  • Shows new delegation pattern
  • Ready to copy-paste
• Complete skill implementations
  • Full SKILL.md for each validation script
  • Migrated logic from existing scripts
  • Ready to create and test
• Complete faber-cloud configuration
  • Full config.json with all settings
  • All hooks configured
  • All environments configured
• Step-by-step testing with actual commands
• Rollback procedures specific to the project

The adoption spec is designed to be handed to another Claude Code session for immediate implementation.

Step 8: Get User Confirmation

Ask user if they want to proceed:

❓ Ready to install faber-cloud configuration?

This will:
  ✓ Copy config.json to .fractary/​plugins/​faber-cloud/
  ✓ Set up directory structure
  ✓ Enable faber-cloud lifecycle management

You can:
  1. Proceed now (recommended after review)
  2. Review reports first (.fractary/​adoption/)
  3. Test with dry-run in test environment

Proceed with installation? (yes/​no)

If dry-run mode: Skip this step, display reports only

Step 9: Install Configuration (if approved)

If user approves installation:

1. Create target directory:

   mkdir -p .fractary/​plugins/​faber-cloud
   

2. Copy configuration:

   cp {output_dir}/​config.json .fractary/​plugins/​faber-cloud/
   

3. Validate installation:

   bash plugins/​faber-cloud/​skills/​infra-adoption/​scripts/​validate-generated-config.sh \
     .fractary/​plugins/​faber-cloud/​config.json
   

4. Display success message:

   ✅ faber-cloud configuration installed!
   
   Next steps:
   1. Review MIGRATION.md for detailed checklist
   2. Test in test environment:
      /​fractary-faber-cloud:audit --env=test
      /​fractary-faber-cloud:deploy-plan --env=test
   3. Follow migration checklist step-by-step
   4. Gradually roll out (test → staging → prod)
   

If user declines:

ℹ️  Configuration not installed

Reports saved to {output_dir}/:
- config.json (ready to install)
- MIGRATION.md (migration guide)
- discovery-*.json (discovery reports)

To install later:
1. Review the reports
2. Run /​fractary-faber-cloud:adopt again
3. Or manually copy configuration

Input:

• Flat Terraform directory (./​terraform/)
• test.tfvars and prod.tfvars
• 2 AWS profiles (project-test, project-prod)
• No custom agents

Output:

Structure: Flat
Complexity: Simple
Migration Time: 1-2 hours
Recommendation: Straightforward adoption, minimal configuration needed

Example: Complex Multi-Site

Input:

• Modular Terraform (./​terraform/​modules/, ./​terraform/​environments/)
• Multiple environments (dev, test, staging, prod)
• 8 AWS profiles with complex naming
• Custom agents for deploy, audit, debug

Output:

Structure: Multi-environment with modules
Complexity: Complex
Migration Time: 1-2 days
Recommendations:
  - Map custom deploy scripts to pre-deploy hooks
  - Integrate audit script as standalone audit skill
  - Review module dependencies carefully

</​EXAMPLES>

<ERROR_HANDLING>

No Terraform Found

If Terraform discovery returns no results:

• Check if project uses different IaC tool (CDK, Pulumi, etc.)
• Suggest manual configuration creation
• Offer to set up greenfield faber-cloud config

No AWS Profiles Found

If AWS discovery returns no profiles:

• Check if using environment variables instead
• Suggest creating profiles for faber-cloud
• Offer profile setup wizard

Custom Agents Not Version Controlled

If custom scripts not in git:

• WARN user about risk of losing scripts
• Recommend committing before migration
• Offer to backup scripts to .fractary/​backup/ </​ERROR_HANDLING>
