Agent4

Agent4 is a rebuilt learning and assessment platform for SolidWorks modeling and ANSYS simulation education.

It separates the product into these roles:

• Knowledge standards: standard answers, extracted skillflows, teaching scripts, and assessment rules.
• Learning controller: teaching and testing sessions.
• C# backend: learning/testing API, SolidWorks extraction orchestration, and method-sensitive grading.
• Extractors: SolidWorks part and assembly feature extraction tools.
• Grader: compares student extracted operations with standard answers.
• Web workbench: teaching/testing UI.

Current Scope

This first rebuild focuses on SolidWorks feature-process learning:

1. Search standard answers from the reducer knowledge framework and local skillflow JSON files.
2. Start a teaching session from a standard answer.
3. Generate step voice text from the expected SolidWorks feature operation.
4. Accept observed student steps or extract a submitted .SLDPRT.
5. Compare feature method and core parameters.
6. Start a testing session and produce a grade report.

Run Backend

cd D:\CSharpProjects\agent3\agent4
.\run_backend.ps1

Backend URL:

http://127.0.0.1:7200

The default backend is now the C# API:

backend-csharp/Agent4.Api

The earlier Python FastAPI backend remains as a fallback/reference and can be started with:

.\run_backend_python.ps1

Important APIs

GET  /health
GET  /api/standards?query=榻胯疆
GET  /api/standards/{standard_id}
POST /api/teaching/sessions
POST /api/teaching/sessions/{session_id}/observations
POST /api/teaching/sessions/{session_id}/audit-part
POST /api/testing/sessions
POST /api/testing/sessions/{session_id}/submit

Extractor Tools

The rebuilt project copies the existing extraction tools into:

tools/modeling-process/PartFeatureAudit
tools/modeling-process/AssemblyKnowledgeAudit

PartFeatureAudit is the core for method-sensitive judgment. It can distinguish feature methods such as boss extrude, cut extrude, shell, loft, sweep, hole wizard, mirror, fillet, chamfer, linear pattern, and circular pattern.

Import Standard Records

Extracted records such as *_modeling_plan.json, *_skill_flow.json, and *_skill_flow_validation.json should be imported as standard-answer assets:

cd D:\CSharpProjects\agent3
.\.venv\Scripts\python.exe agent4\scripts\import_standard_records.py --source "D:\Desktop\鎻愬彇璁板綍" --target "D:\CSharpProjects\agent3\agent4\data\standards"

The importer copies records into categorized folders and writes:

agent4/data/standards/manifest.json

The manifest is the main lookup index for teaching and testing. The raw JSON files remain the authority for executable and comparable feature traces.

Architecture Direction

Agent4 should judge student work from extracted SolidWorks feature traces, not from UI button clicks.

standard answer skillflow
  -> expected feature trace
student model or operation
  -> extracted feature trace
grader
  -> teaching feedback or test score

Final geometry comparison is secondary. Feature method correctness is primary for teaching.
