Posted to Show HN today with almost no votes yet, compactdiff diffs an agent session before and after compaction so you can see which context the harness discarded. Small tool, real unmeasured failure mode: every long-running agent silently drops state at compaction and nobody audits what went. Unproven traction, single source. But it's the observability counterpart to durable-state harnesses like prime-agent, which try to make context survive rather than showing you what didn't.

Posted to Show HN with observe, click, type and scroll tools for any harness. Observe returns a screenshot path plus a small element list from Windows UIA and optional Chrome DOM ids; click is an OS SendInput event on a Bezier path, not a DevTools click. No Playwright, no Pupp...
In the last 19 hours, every AI submission landed in single digits: Tura ("build agent that uses 80% less token," 7), 49IDE (a 2D grid IDE for managing many agents, git trees and issues, 8), Aidress (LangChain integration for cross-agent discovery and trust, 2), Faaah (filesyst...
Buried at 4 points on Show HN, which is a shame, because it's the most consequential idea in today's Show HN cluster. Every MCP server you connect burns context on tool schemas before the agent does any work, and aggregation behind a two-tool facade is the obvious fix nobody h...
Four projects in 24 hours: CCN ("nuking the crap Claude left in the codebase"), Galda (return to Claude Code/Codex sessions without digging through git), evidence-to-skill (a gate between untrusted sources and agent skills), and claude-copy. None has traction individually: mos...
Participants with AI assistance got 9% of answers right. The baseline group, no assistance, got 27%. Three times worse. And their self-reported confidence went from 30% to 76%. The research comes from University of Milano-Bicocca, École Normale Supérieure, and Sapienza, and th...
Show HN: the developer behind JUCE and Cmajor launched an open-source agent where sessions are Yjs-backed CRDT documents instead of chat logs, and nearly everything (context items, loop strategies, slash commands) is a forkable JavaScript plugin. Go plus Wails backend to dodge...
