Its authors report that grounding tasks in executed tool-call chains creates tougher evaluations and improves results on seven benchmarks. For AI builders, the central idea is that an agent task should be executable and checkable, not merely plausible in prose.","published_at":"2026-11-06","updated_at":"2026-11-06","record_date":"2026-11-06","date_kind":"published_at","topics":["mcp","claude"],"entities":["ToolSpace","MCP","AutomationBench","tau3-Bench Banking","Qwen3.6-35B-A3B","GLM-5.2","Claude Opus 5"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"ToolSpace adds an execution-grounded method for synthesizing MCP environments and reports substantial benchmark gains, including improved scores for Qwen3.6-35B-A3B and GLM-5.2.","prior_refs":[],"source_url":"https://arxiv.org/abs/2611.05036","source_urls":["https://arxiv.org/abs/2611.05036"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:toolspace-scaling-tool-centric-environment-synthesis-for-long-1b4a89","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/toolspace-scaling-tool-centric-environment-synthesis-for-long-1b4a89/","markdown":"https://newruntime.com/posts/toolspace-scaling-tool-centric-environment-synthesis-for-long-1b4a89.md","json":"https://newruntime.com/posts/toolspace-scaling-tool-centric-environment-synthesis-for-long-1b4a89.json"},"markdown_url":"https://newruntime.com/posts/toolspace-scaling-tool-centric-environment-synthesis-for-long-1b4a89.md","next_reads":[{"type":"topic","path":"/topics/mcp/","url":"https://newruntime.com/topics/mcp/","title":"Mcp","reason":"Explore the mcp topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/mcp.md","json_url":"https://newruntime.com/topics/mcp.json"},{"type":"topic","path":"/topics/claude/","url":"https://newruntime.com/topics/claude/","title":"Claude","reason":"Explore the claude topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude.md","json_url":"https://newruntime.com/topics/claude.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
