Identify C2-level containers (deployable units) from systems	init-json-path	Task, Read, Bash

Identify C2 Containers

Analyze systems and identify C2-level containers (deployable/runnable units) using C4 Model methodology.

Context

• Init file: ${1:-init.json}
• C1 systems file: ${2:-c1-systems.json}
• Status: !test -f ${1:-init.json} && test -f ${2:-c1-systems.json} && echo "✓ Files exist" || echo "✗ Missing files"

Prerequisites

Before running this command:

1. Run /melly-init first to generate init.json
2. Run /melly-c1-systems to generate c1-systems.json

What This Command Does

1. Validates prerequisites - Checks init.json and c1-systems.json exist
2. Launches c2-abstractor agent - Applies C4 Level 2 methodology
3. Identifies containers - Deployable units (SPA, API, databases, caches, etc.)
4. Detects technology stacks - Languages, frameworks, libraries, versions
5. Analyzes runtime environments - Where and how containers run
6. Maps communication - How containers interact (REST, gRPC, database, etc.)
7. Generates c2-containers.json - Structured output with observations and relations
8. Validates output - Ensures schema compliance and referential integrity

Workflow

Use the Task tool to launch the c2-abstractor agent with:

• Input: init.json, c1-systems.json
• Methodology: c4model-c2 skill (automatic activation)
• Output: c2-containers.json

After agent completes:

• Validate: cat c2-containers.json | python ${CLAUDE_PLUGIN_ROOT}/validation/scripts/validate-c2-containers.py
• Report results summary
• Suggest next step: /melly-c3-components or /melly-doc-c4model

Next Steps

After successful completion:

• Option 1: Run /melly-c3-components to analyze component structure
• Option 2: Run /melly-doc-c4model to generate documentation
• Option 3: Manually inspect c2-containers.json for accuracy

Troubleshooting

• Missing init.json: Run /melly-init first
• Missing c1-systems.json: Run /melly-c1-systems first
• Validation fails: Check error messages, fix issues in c2-containers.json
• Timestamp errors: Ensure c2 timestamp > c1 timestamp > init timestamp
