OpenCode is testing background compaction with a quieter interface, and Zed 1.25.2 turns on context compaction for external agents connected through ACP. Long sessions will increasingly run on summaries of earlier work, so whatever a summary leaves out is effectively gone for the agent unless it is written down somewhere outside the conversation.","verification_level":"source-linked","signal_type":"synthesis","synthesis_of":[{"slug":"claude-code-2-1-311-speeds-pro-max-9f4329","title":"Claude Code 2.1.311 speeds Pro/Max startup and keeps compacting past 200K tokens","url":"https://newruntime.com/posts/claude-code-2-1-311-speeds-pro-max-9f4329/"},{"slug":"opencode-s-experimental-background-compaction-setting-lands-in-0dafb8","title":"OpenCode's experimental background compaction setting lands in dev builds, with a quieter compaction UI merged Oct 25","url":"https://newruntime.com/posts/opencode-s-experimental-background-compaction-setting-lands-in-0dafb8/"},{"slug":"zed-1-25-2-stable-cuts-binary-size-6413ee","title":"Zed 1.25.2 stable cuts binary size by about 33% on macOS, 28% on Windows and 7% on Linux","url":"https://newruntime.com/posts/zed-1-25-2-stable-cuts-binary-size-6413ee/"}],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"signal:coding-agents-now-compact-the-conversation-and-keep-going-instead-of-s-b20967","retrieval_nugget":"311 compacts sessions that pass 200K tokens and continues instead of stopping with a credits message. 2 turns on context compaction for external agents connected through ACP.","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/signals/coding-agents-now-compact-the-conversation-and-keep-going-instead-of-s-b20967/","markdown":"https://newruntime.com/signals/coding-agents-now-compact-the-conversation-and-keep-going-instead-of-s-b20967.md","json":"https://newruntime.com/signals/coding-agents-now-compact-the-conversation-and-keep-going-instead-of-s-b20967.json"},"next_reads":[{"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":"topic","path":"/topics/claude-code/","url":"https://newruntime.com/topics/claude-code/","title":"Claude Code","reason":"Explore the claude-code topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude-code.md","json_url":"https://newruntime.com/topics/claude-code.json"},{"type":"topic","path":"/topics/coding-agents/","url":"https://newruntime.com/topics/coding-agents/","title":"Coding Agents","reason":"Explore the coding-agents topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/coding-agents.md","json_url":"https://newruntime.com/topics/coding-agents.json"},{"type":"collection","path":"/signals/","url":"https://newruntime.com/signals/","title":"Raw Signals","reason":"Open every source-linked raw signal.","media_type":"text/html","json_url":"https://newruntime.com/signals.json"},{"type":"collection","path":"/source-ledger.json","url":"https://newruntime.com/source-ledger.json","title":"Source Ledger","reason":"Inspect the public source evidence graph.","media_type":"application/json"}]}
