Model Evaluation Benchmark Skill

Purpose: Automated reproduction of comprehensive model evaluation benchmarks following the Benchmark Suite V3 reference implementation.

Auto-activates when: User requests model benchmarking, comparison evaluation, or performance testing between AI models in agentic workflows.

Skill Description

This skill orchestrates end-to-end model evaluation benchmarks that measure:

• Efficiency: Duration, turns, cost, tool calls

• Quality: Code quality scores via reviewer agents

• Workflow Adherence: Subagent calls, skills used, workflow step compliance

• Artifacts: GitHub issues, PRs, documentation generated

The skill automates the entire benchmark workflow from execution through cleanup, following the v3 reference implementation.

When to Use

✅ Use when:

• Comparing AI models (Opus vs Sonnet, etc.)

• Measuring workflow adherence

• Generating comprehensive benchmark reports

• Need reproducible benchmarking

❌ Don't use when:

• Simple code reviews (use reviewer )

• Performance profiling (use optimizer )

• Architecture decisions (use architect )

Execution Instructions

When this skill is invoked, follow these steps:

Phase 1: Setup

• Read tests/benchmarks/benchmark_suite_v3/BENCHMARK_TASKS.md

• Identify models to benchmark (default: Opus 4.5, Sonnet 4.5)

• Create TodoWrite list with all phases

Phase 2: Execute Benchmarks

For each task × model:

cd tests/benchmarks/benchmark_suite_v3 python run_benchmarks.py --model {opus|sonnet} --tasks 1,2,3,4

Phase 3: Analyze Results

• Read all result files: ~/.amplihack/.claude/runtime/benchmarks/suite_v3/*/result.json

• Launch parallel Task tool calls with subagent_type="reviewer" to:

• Analyze trace logs for tool/agent/skill usage

• Score code quality (1-5 scale)

• Synthesize findings

Phase 4: Generate Report

• Create markdown report following BENCHMARK_REPORT_V3.md structure

• Create GitHub issue with report

• Archive artifacts to GitHub release

• Update issue with release link

Phase 5: Cleanup (MANDATORY)

• Close all benchmark PRs: gh pr close {numbers}

• Close all benchmark issues: gh issue close {numbers}

• Remove worktrees: git worktree remove worktrees/bench-*

• Verify cleanup complete

See tests/benchmarks/benchmark_suite_v3/CLEANUP_PROCESS.md for detailed cleanup instructions.

Example Usage

User: "Run model evaluation benchmark"Assistant: I'll run the complete benchmark suite following the v3 reference implementation.

[Executes phases 1-5 above]

Final Report: See GitHub Issue #XXXX Artifacts: https://github.com/.../releases/tag/benchmark-suite-v3-artifacts
