Test the Tool Names Fix - BACKEND RESTARTED ✅

Status

✅ Backend has been restarted with the fixed code ✅ The tool_names variable has been removed from prompt template ✅ Server is running on http://0.0.0.0:8000

What Changed

File: Ai_powered_interview_coach/backend/app/services/agents/resume_agent_service.py

Before:

return PromptTemplate(
    template=template,
    input_variables=["input", "tools", "tool_names", "agent_scratchpad"]
)

After:

return PromptTemplate(
    template=template,
    input_variables=["input", "tools", "agent_scratchpad"]
)

How to Test

Step 1: Upload a New Resume

  1. Go to the frontend (http://localhost:3000 or your frontend URL)
  2. Upload a new resume file
  3. The resume will be processed through:
    • Text extraction
    • Skill extraction
    • AI analysis (this is where the fix applies)

Step 2: Monitor Backend Logs

Watch for these messages in the backend logs:

Good Signs ✅:

Agent initialized with 6 tools, max_iterations=8, max_execution_time=60.0s
Agent executed successfully in XXXms with X reasoning steps
Agent output successfully validated and parsed

Bad Signs ❌:

Agent analysis failed: Prompt missing required variables: {'tool_names'}

Step 3: Check Analysis Status

After ~30-60 seconds, check the resume analysis:

  • Status should be: "success" (not "fallback")
  • Analysis should contain: AI-generated insights, not generic recommendations
  • Fields should have: Real data from the resume, not placeholder values

Expected Results

Before Fix (What You Were Seeing)

{
  "status": "fallback",
  "analysis_data": {
    "skill_inventory": {
      "tools": ["Render", "Docker", ...],
      "note": "Fallback analysis - generic recommendations"
    },
    "fallback_used": true
  }
}

After Fix (What You Should See Now)

{
  "status": "success",
  "analysis_data": {
    "skill_inventory": {
      "technical_skills": [...],
      "soft_skills": [...],
      "tools": [...]
    },
    "experience_timeline": {
      "positions": [...],
      "progression": "..."
    },
    "skill_gaps": {
      "missing_skills": [...],
      "recommendations": [...]
    },
    "improvement_roadmap": {
      "timeline_weeks": 12,
      "milestones": [...]
    },
    "fallback_used": false
  }
}

If Still Seeing Fallback

Check the backend logs for the actual error. Common issues:

  1. Token Limit Error

    • Solution: Reduce max_iterations further (currently 8)
    • Or: Simplify the prompt template
  2. Tool Execution Error

    • Solution: Check if all 6 tools are registered correctly
    • Verify tool implementations
  3. JSON Parsing Error

    • Solution: Check if agent output is valid JSON
    • Verify _validate_and_parse_output method
  4. Different Error

    • Share the exact error message from logs
    • We'll fix it accordingly

Quick Troubleshooting

Backend Not Responding

# Check if backend is running
Get-Process python

# Restart if needed
taskkill /F /IM python.exe
cd Ai_powered_interview_coach/backend
python -m uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

Clear Old Analysis

Delete old analysis records from database to test fresh:

DELETE FROM resume_analyses WHERE status = 'fallback';

View Backend Logs in Real-Time

The backend logs are printed to console. Look for:

  • Agent initialization messages
  • Tool execution messages
  • Final output validation messages
