Research Papers

AutoSaddler: Automated Patching of Agent Harnesses — Microsoft et al.

• Motivation: Agent harness design remains largely hand-tuned, brittle, and difficult to scale across diverse professional workflows.
• Key Innovation: Introduces AutoSaddler, an automated offline optimization loop that treats agent harnesses as code, diagnosing execution failures from traces and generating structured patches for prompts, tool configurations, and control logic.
• Results: Achieved performance boosts of 9.0 points on GAIA2, 9.6 on SWE-Bench Pro, and 10.0 on Terminal-Bench 2.0 over baseline human-tuned harnesses.
• Paper:

  Impressive new paper from Microsoft and colleagues.
  
  Harness design is still hand-tuned almost everywhere. This work present an automated loop to optimize the harness.
  
  They introduce AutoSaddler, which treats the agent harness as code and learns to patch it offline from failure… pic.twitter.com/LbZ7fAfJTu

Evaluation Fragility: Configuration Sensitivity in Open-Source Benchmarks — Independent Research

• Motivation: LLM leaderboards frequently treat benchmark scores as absolute ground truth, overlooking how minor evaluation configuration choices alter model standings.
• Key Innovation: Tested 12 open-source models across 26 equally valid configurations of standard datasets (ARC, MMLU, HellaSwag), systematically modifying option order, prompt wording, and answer parsing methods.
• Results: Demonstrated that a single model’s score can swing wildly from 31% to 89% purely based on evaluation harness configuration, revealing critical vulnerabilities in compressed benchmark selection.
• Paper:

  Great paper on agent harnesses. https://t.co/lsS4eKFGWs

Other Highlights

Memory Triage in Context Compaction

• Overview: Recent research highlights how standard context compaction evicts critical safety rules alongside episodic logs when budgets overflow. Proposed “Knowledge Triage” routing classifies knowledge base lines by type, preserving 2 to 4x more safety rule precision over multi-turn executions.
• Link:

  If you keep safety rules or coding standards in an AGENTS.md or a CLAUDE.md, this one is worth your time.
