description	Run application assessment for a single repository

Application Assessment

This skill performs application assessment for a single repository. It supports Java, .NET, and JavaScript/TypeScript projects.

Input Parameters

• workspace-path (optional): Path to the project to assess. Defaults to the current directory (repository root) when not specified. All assessment outputs are written relative to this path (e.g. {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json). For a repository with multiple sub-projects, pass the sub-project directory path so that each sub-project's outputs are isolated.

When to Use This Skill

Use this skill when you need to:

• Assess a Java or .NET application for cloud readiness and migration issues
• Assess a JavaScript/TypeScript project for outdated dependencies and available updates
• Generate detailed assessment reports with issue analysis and recommendations
• Understand application dependencies, frameworks, and potential migration blockers

What This Skill Does

This skill performs a simplified assessment workflow:

1. Check Project Type and Prerequisites:

   • For Java projects: Check MCP tool availability in this order:
     1. Primary: Check if 'appmod-run-assessment-action' MCP tool is available
        • If available, use ONLY this tool. It handles everything (prerequisite checks, installation, and assessment execution) in a single call.
        • Do NOT call any other assessment MCP tools when this tool is available.
     2. Fallback: If 'appmod-run-assessment-action' is NOT available, check if 'appmod-precheck-assessment' MCP tool is available
        • If available, use the legacy workflow: call 'appmod-precheck-assessment' first, then follow its guidance for 'appmod-install-appcat' and 'appmod-run-assessment'.
     3. If neither tool is configured, return immediately with setup instructions.
   • For .NET projects: Check if .NET SDK is available
     • No MCP tools required for .NET assessment
   • For JavaScript/TypeScript projects: Check if Node.js and npm are available
     • No MCP tools required for JS/TS assessment

2. Run Assessment:

   • For Java projects: Trigger AppCAT analysis via Assessment MCP server
     • If 'appmod-run-assessment-action' is available (primary path):
       • Call 'appmod-run-assessment-action' MCP tool only
       • The MCP tool automatically saves the report to the versioned directory
     • If falling back to 'appmod-precheck-assessment' (legacy path):
       • Call 'appmod-precheck-assessment' to check prerequisites
       • Call 'appmod-install-appcat' to install AppCAT if needed
       • Call 'appmod-run-assessment' to run the assessment
   • For .NET projects: Install and run AppCAT directly
     • Install: dotnet tool update dotnet-appcat
     • Find all .csproj files under {workspace-path}
     • Join project paths with semicolons: projectPaths="project1.csproj;project2.csproj"
     • Run: appcat analyze $projectPaths --source Solution --target Any --serializer APPMODJSON --code --privacyMode Restricted --non-interactive --report {workspace-path}\.github\modernize\appcat\result\report.json
   • For JavaScript/TypeScript projects: Install and run npm-check-updates
     • Install: npm install -g npm-check-updates@19.6.3 --prefix {tool-install-dir}
     • Run: ncu --format group --packageFile {workspace-path}/package.json
     • Generate the reportId as a UTC timestamp formatted as yyyyMMddHHmmss (e.g. 2024-06-15T14:30:52Z becomes 20240615143052)
     • Create the versioned directory: mkdir -p {workspace-path}/.github/modernize/assessment/reports/report-{reportId}
     • Save the output to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/js-assessment-report.md
     • Do NOT save a copy to the top-level assessment directory
   • Analyzes code for cloud migration issues or dependency updates
   • Generates structured assessment data

3. Save Report to Versioned Directory (All languages):

   • For Java projects (primary path — 'appmod-run-assessment-action'): The MCP tool automatically saves the report to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json — no manual saving needed
   • For Java projects (legacy fallback path — 'appmod-precheck-assessment'):
     1. Find report.json under {workspace-path}/.github/modernize/appcat/result/
     2. Read the report and extract metadata.analysisStartTime
     3. Format the timestamp as yyyyMMddHHmmss to produce the reportId (e.g. 2024-06-15T14:30:52Z becomes 20240615143052)
     4. Create the versioned directory: mkdir -p {workspace-path}/.github/modernize/assessment/reports/report-{reportId}
     5. Move the report to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json
   • For .NET projects:
     1. Find report.json at {workspace-path}/.github/modernize/appcat/result/report.json
     2. Read the report and extract metadata.analysisStartTime
     3. Format the timestamp as yyyyMMddHHmmss to produce the reportId (e.g. 2024-06-15T14:30:52Z becomes 20240615143052)
     4. Create the versioned directory: mkdir -p {workspace-path}/.github/modernize/assessment/reports/report-{reportId}
     5. Move the report to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json
   • This versioned report should be included in the pull request

How to Use

Prerequisites

For Java projects:

• Primary: MCP tool 'appmod-run-assessment-action' — preferred, handles everything in one call
• Fallback: If primary tool is not available, use 'appmod-precheck-assessment' → 'appmod-install-appcat' → 'appmod-run-assessment' workflow
• If neither tool is configured, the skill will return instructions for setup

For .NET projects:

• .NET SDK must be installed
• No MCP tools required - appcat will be installed and run directly via .NET CLI
• The assessment will automatically install dotnet-appcat tool if not already present

For JavaScript/TypeScript projects:

• Node.js and npm must be installed
• No MCP tools required - npm-check-updates will be installed and run directly via npm
• The assessment will automatically install npm-check-updates if not already present

Triggering Assessment

Simply express the intent to assess the application. Example prompts:

• "Assess the application"
• "Run assessment for this project"

The assessment process automatically:

• Detects project language and framework within {workspace-path}
• For Java: Uses MCP tool to run AppCAT and automatically save report to versioned directory
• For .NET: Installs dotnet-appcat tool and runs analysis directly
• For JavaScript/TypeScript: Installs npm-check-updates and runs dependency analysis
• Executes comprehensive analysis
• For Java (primary): Report is automatically saved to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json
• For Java (legacy fallback): Generates report at {workspace-path}/.github/modernize/appcat/result/, then moved to versioned directory
• For .NET: Generates report at {workspace-path}/.github/modernize/appcat/result/report.json
• For JavaScript/TypeScript: Generates report at {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/js-assessment-report.md

Report Saving

For Java projects:

1. If using 'appmod-run-assessment-action' (primary path): The MCP tool automatically saves the report to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json — no manual report moving is needed
2. If using legacy fallback path ('appmod-precheck-assessment'):
   • Find report.json under {workspace-path}/.github/modernize/appcat/result/
   • Read the report and extract metadata.analysisStartTime, format as yyyyMMddHHmmss to get reportId
   • Move the report to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json
3. Include this versioned report in the pull request

For .NET projects:

1. Report is initially generated at {workspace-path}/.github/modernize/appcat/result/report.json
2. Read the report and extract metadata.analysisStartTime, format as yyyyMMddHHmmss to get reportId
3. Move the report to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json
4. Include this versioned report in the pull request

For JavaScript/TypeScript projects:

1. Generate the reportId as a UTC timestamp formatted as yyyyMMddHHmmss (e.g. 2024-06-15T14:30:52Z becomes 20240615143052)
2. Create the versioned directory: mkdir -p {workspace-path}/.github/modernize/assessment/reports/report-{reportId}
3. Save the ncu output to {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/js-assessment-report.md
4. Include this versioned report in the pull request

Report Output Location

Report location depends on project type:

For Java projects (via MCP server):

• Primary path ('appmod-run-assessment-action'): Automatically saved to: {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json
• Legacy fallback path ('appmod-precheck-assessment'): Initially stored under {workspace-path}/.github/modernize/appcat/result/, then moved to versioned directory: {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json

For .NET projects (direct execution):

• Initially generated at: {workspace-path}/.github/modernize/appcat/result/report.json
• Moved to versioned directory: {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json

For JavaScript/TypeScript projects (direct execution):

• Saved to versioned directory: {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/js-assessment-report.md

Success Criteria

Assessment is complete when:

• ✅ For Java: MCP server is available (or clear instructions provided if not)
• ✅ For .NET: .NET SDK is available and dotnet-appcat tool is installed
• ✅ For JavaScript/TypeScript: Node.js and npm are available and npm-check-updates is installed
• ✅ AppCAT analysis executes without errors (Java/.NET) or ncu analysis executes without errors (JS/TS)
• ✅ For Java and .NET: Report generated at {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/report.json
• ✅ For JavaScript/TypeScript: Report generated at {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/js-assessment-report.md
• ✅ Report metadata includes assessment tool version, timestamp, and configuration

Troubleshooting

Prerequisites Not Met:

• For Java: First check for 'appmod-run-assessment-action', then fall back to 'appmod-precheck-assessment'
  • Return immediately with setup instructions if neither tool is available
  • Do not attempt to run assessment without MCP
• For .NET: Verify .NET SDK is installed
  • Check with dotnet --version command
  • Provide installation instructions if .NET SDK is missing
• For JavaScript/TypeScript: Verify Node.js and npm are installed
  • Check with npm --version command
  • Provide installation instructions if npm is missing

Assessment Failures:

• Unsupported project type (only Java, .NET, and JavaScript/TypeScript supported)
• For Java: MCP server communication errors
• For .NET:
  • dotnet-appcat tool installation failure
  • appcat command execution errors
• For JavaScript/TypeScript:
  • npm-check-updates installation failure
  • ncu command execution errors
  • No package.json found at {workspace-path}/package.json
• Invalid project structure or build configuration

Report Generation Issues:

• For Java (primary): No report.json found under {workspace-path}/.github/modernize/assessment/reports/report-*/report.json after MCP execution
• For Java (legacy fallback): No report.json found under {workspace-path}/.github/modernize/appcat/result/ after MCP execution
• For .NET: Report not generated at {workspace-path}/.github/modernize/appcat/result/report.json, or metadata.analysisStartTime missing from report
• For JavaScript/TypeScript: Report not generated at {workspace-path}/.github/modernize/assessment/reports/report-{reportId}/js-assessment-report.md
• Report file is corrupted or invalid JSON (Java/.NET only)

For any failure, provide clear error messages and troubleshooting steps.
