Each task was judged 7 times by a blind LLM grader. The rankings were strongly consistent across rounds (Kendall's W = 0.67).

What Makes It Work

Key Strengths

◆ Structured Data Mastery
Excels at expense reconciliation, board meeting materials, and complex data organization tasks.
◆ Document Generation
Top performer on travel itineraries, meeting notes, and multi-format output tasks.
◆ Breadth of Capability
Highest raw score across all 58 tasks demonstrates consistent performance, not just isolated wins.

Growth Opportunities

◆ Case Study & Deck Tasks
Opportunity to improve on longer-form narrative and onboarding-deck style tasks where more creative structuring is needed.
◆ Timeout Optimization
Some complex tasks approach time limits. Better resource budgeting could recover additional points.
◆ Artifact Completion
"Built but didn't finalize" pattern shows the reasoning is sound — tightening output completion is a clear path to higher scores.

Building Confidence in the Results

Strong results only matter if you can trust the harness that produced them. We invested heavily in making ours reliable, fast, and fair.

! Before v0.32 (old benchmarking harness)
  • Monolithic harness with linear execution
  • Infrastructure flakiness polluted agent scores
  • Idle Docker containers wasting resources
  • Scattered config across multiple file types
After v0.36 (rebuilt eval-recipes harness)
  • DAG-based parallel job execution
  • Intelligent failure classification
  • SQLite-persisted state for resumability
  • Soft dependencies so partial failures never block results

A Complete Benchmarking Overhaul

Five PRs. One vision: a benchmarking harness rigorous enough to trust the results it produces.

Infrastructure Highlights

Purpose-built primitives for reliable, parallelized agent evaluation.

DAG-Based Job Framework
Typed, directed acyclic graph runner with parallel execution, SQLite-persisted state for resumability, soft dependencies so partial failures never block results, and automatic cycle detection.

Failure Classification
  • AGENT_ERROR — real agent issue, counts
  • INFRASTRUCTURE_ERROR — flaky infra, excluded
  • TEST_ISSUE — benchmark bug, excluded

Only infrastructure errors set valid_trial=false, keeping agent scores clean.

In-Container Analysis
  • analysis_runner.py runs inside Docker
  • Full filesystem access to explore failures
  • Score threshold (≥85.0) skips costly analysis
  • 7-run comparison with Kendall's W agreement

62.5% overall.
100% on eight tasks.
#1 on the hardest comparisons.

245 files changed. 10,843 lines of infrastructure.
A rigorous harness that gives us confidence in the results.
