Results should be read within the paper's tasks and tool environment rather than as a universal rule.","published_at":"2026-08-14","updated_at":"2026-08-15","record_date":"2026-08-14","date_kind":"discovered_at","topics":["tool-calling","research","evals"],"entities":["The Bitter Lesson of Tool Calling"],"source_urls":["https://arxiv.org/abs/2608.06370"],"source_format":"research_paper","editorial_timing":{"lane":"regular_hourly","scheduled_at":"2026-08-19T17:00:00+03:00","real_news_delta":"owner-selected verified story"},"origin":{"basket_id":"5854f7b2-5954-4d2a-8997-81596a49da74","basket_revision":1,"target_kind":"story_cluster","target_id":"97104458-3d8f-4378-9bad-01ab380528ed","owner_selection":"18","route":"openclaw"},"visual_decision":{"outcome":"text_only","status":"not_applicable","reason_code":"concise_text_sufficient","owner_reviewed":true,"reviewed_by":"owner-and-codex"},"schema_version":"newruntime-agent-readable-v0.2","status":"published","visuals":[],"routes":{"html":"https://newruntime.com/posts/the-bitter-lesson-of-tool-calling-tests-general-learning-against-hand-built-schemas/","markdown":"https://newruntime.com/posts/the-bitter-lesson-of-tool-calling-tests-general-learning-against-hand-built-schemas.md","json":"https://newruntime.com/posts/the-bitter-lesson-of-tool-calling-tests-general-learning-against-hand-built-schemas.json"}}
