# RecruitmentAssistant-H_A2A Evaluation Scripts

This directory contains evaluation scripts for analyzing the RecruitmentAssistant-H_A2A (Hybrid A2A) project results.

## Architecture

This project uses a hybrid Agent-to-Agent (A2A) architecture:
- **LangGraph** - Job Analysis stage with dynamic batched tool execution
- **CrewAI** - Candidate Evaluation stage with standard CrewAI structure  
- **AutoGen** - Interview Communication stage with flexible LLM/tool patterns

## Scripts

### 1. analyze_retry_patterns.py
Analyzes RETRY patterns in execution paths.

**Features:**
- Counts error occurrences by location and type
- Calculates RETRY rates per model
- Identifies maximum RETRY attempts
- Tracks errors by agent and node type

**Output:**
- `retry_analysis.json` - Detailed JSON results
- `retry_summary.csv` - Summary statistics
- `error_by_agent.csv` - Error breakdown by agent

**Usage:**
```bash
python3 analyze_retry_patterns.py
```

### 2. evaluate_success.py
Calculates success rates for each model.

**Success Criteria:**
- Reports folder exists
- Contains at least 2 markdown files

**Output:**
- `success_detailed_results.json` - Detailed results per session
- `success_rate.csv` - Success rate summary

**Usage:**
```bash
python3 evaluate_success.py
```

### 3. evaluate_trajectory-mix.py
Evaluates trajectory metrics with hybrid architecture support.

**Special Features:**
- **Dynamic LangGraph matching** - Handles batched tool execution patterns (3-4 searches)
- **AutoGen LLM insertion** - Flexible LLM call patterns between tools
- **Tool order permutation** - Evaluates different tool call orders

**Metrics:**
- Exact match
- In-order match
- Any-order match
- Precision
- Recall
- Single-tool use
- Path diversity (unique path ratio, path entropy)

**Output:**
- `evaluation_results.csv` - Trajectory evaluation results

**Usage:**
```bash
python3 evaluate_trajectory-mix.py --config reference_trajectory.yaml
```

### 4. reference_trajectory.yaml
Configuration file defining reference trajectories and evaluation parameters.

**Key Sections:**
- `reference_trajectory_3x` - Reference for 3 web searches
- `reference_trajectory_4x` - Reference for 4 web searches
- `target_tools` - Required tools for evaluation
- `models` - List of models to evaluate
- `permutable_tool_groups` - Tool groups that can appear in any order
- `extract_types` - Node types to extract (SPAN, Chain, AGENT, LLM, Tool)

## Dynamic Matching

The hybrid architecture requires sophisticated matching:

### Layer 1: LangGraph Tools Batching
- 3 searches: 4 grouping patterns `[1,1,1]`, `[1,2]`, `[2,1]`, `[3]`
- 4 searches: 7 grouping patterns `[1,1,1,1]`, `[2,1,1]`, `[1,2,1]`, `[1,1,2]`, `[3,1]`, `[1,3]`, `[4]`

### Layer 2: AutoGen LLM Insertion
- 2 tools: 2 patterns (0 or 1 LLM between tools)
- 3 tools: 4 patterns (2^2 combinations)

### Layer 3: Tool Order Permutation
- Candidate evaluation tools can appear in any order
- Interview communication tools can appear in any order

**Total combinations:** Up to 7 × 2 × (permutations) variants per sample

## Configuration

Edit `reference_trajectory.yaml` to:
- Modify reference trajectories
- Add/remove models
- Adjust tool evaluation criteria
- Configure dynamic matching patterns
- Enable/disable pattern matching layers

## Requirements

- Python 3.7+
- pandas
- pyyaml

Install dependencies:
```bash
pip install pandas pyyaml
```

## Data Structure

Expected directory structure:
```
/Users/wzr/TOSEM-2025/RESULTS/
├── ModelName/
│   └── RecruitmentAssistant-H_A2A/
│       └── test_results/
│           ├── session_1/
│           │   ├── execution_path.md
│           │   └── reports/

```

## Notes

- The hybrid architecture requires more flexible matching than standard frameworks
- Dynamic reference selection adapts to different model execution strategies
- All scripts output CSV files for easy analysis
- JSON files contain detailed per-session information
- Modify `BASE_DIR` in scripts if using a different results directory
- The evaluation automatically selects the best-matching reference variant per sample
