Pipeline notes

The summary and note below are generated by the signal pipeline — they are Beyond Desk’s reading, not quotations from the source.

IBM Research introduces consistency guidelines in ALTK-Evolve, a tool that measures and improves agent task consistency. On AppWorld, a ReAct agent with GPT-4.1 succeeded 77.4% across runs but only 53.0% consistently, a 24.4-point gap most benchmarks hide.

Highlights a concrete reliability metric (consistency vs average success) most agent evaluations miss, paired with a tool readers can apply to their own agent pipelines.
