Longest continuous coding-agent runs (wall-clock span, ≤30 min idle between messages): 1. **8h 14m** — opencode, sema, Jun 27 2026 — 1,381 msgs, "Codebase review with 3 improvements" 2. **8h 02m** — codex, vector_editor, Aug 2 2026 — 1,935 msgs (max gap 11m), "gaps in SVG support" 3. **7h 23m** — claude, sema_lisp, Jul 1 2026 — 545 msgs, reviewing the sema-coder-agent-primitives worktree If you count raw session span rather than continuous activity, old ChatGPT/Claude.ai threads win (578 days), but those are sporadic chats, not agentic runs.
