# 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
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
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
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
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
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
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:
   ```bash
   mkdir -p .fractary/plugins/faber-cloud
   ```

2. Copy configuration:
   ```bash
   cp {output_dir}/config.json .fractary/plugins/faber-cloud/
   ```

3. Validate installation:
   ```bash
   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
   ```

**OUTPUT COMPLETION MESSAGE:**
```
✅ COMPLETED: Infrastructure Adoption

</OUTPUTS>

<EXAMPLES>
## Example: Simple Flat Structure

**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>
