# Loki Mode Benchmark Runner
# Run HumanEval and SWE-bench benchmarks to validate multi-agent performance
#
# Usage:
#   ./benchmarks/run-benchmarks.sh [benchmark] [options]
#   ./benchmarks/run-benchmarks.sh humaneval              # Setup only
#   ./benchmarks/run-benchmarks.sh humaneval --execute    # Direct Claude (baseline)
#   ./benchmarks/run-benchmarks.sh humaneval --execute --loki  # Multi-agent Loki Mode
#   ./benchmarks/run-benchmarks.sh humaneval --execute --limit 10  # First 10 problems
#   ./benchmarks/run-benchmarks.sh swebench --execute     # Run SWE-bench
#   ./benchmarks/run-benchmarks.sh all --execute          # Run all benchmarks
#
# Options:
#   --execute       Actually run problems through Claude (vs just setup)
#   --loki          Use Loki Mode multi-agent system (Architect->Engineer->QA->Reviewer)
#   --limit N       Only run first N problems (useful for testing)
#   --parallel N    Run N problems in parallel (default: 1)
#   --model MODEL   Claude model to use (default: sonnet)
#   --timeout N     Timeout per problem in seconds (default: 120)
#   --retries N     Max RARV retry attempts for --loki mode (default: 3)
#
# Prerequisites:
#   - Python 3.8+
#   - Claude Code CLI
#   - Git
#
# Results are saved to:
#   ./benchmarks/results/YYYY-MM-DD-HH-MM-SS/

summary += """## Methodology

Loki Mode uses its multi-agent architecture to solve each problem:
1. **Architect Agent** analyzes the problem
2. **Engineer Agent** implements the solution
3. **QA Agent** validates with test cases
4. **Review Agent** checks code quality

This mirrors real-world software development more accurately than single-agent approaches.

## Running Benchmarks

\`\`\`bash
# Setup only (download datasets)
./benchmarks/run-benchmarks.sh all

# Execute with Claude
./benchmarks/run-benchmarks.sh humaneval --execute
./benchmarks/run-benchmarks.sh humaneval --execute --limit 10  # First 10 only
./benchmarks/run-benchmarks.sh swebench --execute --limit 5    # First 5 only

# Use different model
./benchmarks/run-benchmarks.sh humaneval --execute --model opus
