App Inventory Skill

Overview

The App Inventory Skill provides reusable templates and workflows for systematically inventorying legacy application portfolios. It pairs with the app-inventory agent to produce audit-ready output that feeds into migration planning, sprint estimation, and treatment-matrix decisions.

When to Use This Skill

• Starting a migration factory or modernisation programme
• Onboarding a new application portfolio before sprint planning
• Producing evidence for an architecture review board
• Assessing the blast radius of a dependency upgrade

Templates Included

File	Purpose
inventory-report-template.md	Markdown report for architecture reviews and stakeholders
complexity-scoring-template.md	Scoring worksheet to derive the migration complexity score

Workflow

1. Trigger a scan

Invoke the app-inventory agent and collect its JSON output. Save it alongside the repo or attach it to the relevant GitHub issue.

2. Fill the complexity scoring template

Open complexity-scoring-template.md and rate each of the six dimensions. The weighted total becomes the overall complexity score.

3. Populate the inventory report template

Use the structured scan output to fill inventory-report-template.md. This document becomes the canonical record for that application in the ADR log.

4. Select a treatment path

Bring the complexity score and strategic-value rating to docs/treatment-matrix.md to select Retire, Rehost, Replatform, Refactor, Rebuild, or Replace.

5. Hand off to downstream agents

• Low complexity / Rehost: pass to containerization-planner
• Replatform: pass to legacy-modernization + config-auditor
• Refactor / Rebuild: pass to solution-architect + backend-dev
• Dependency upgrades: pass to dependency-lifecycle
