OpenCode free tier: “1.18.0 or newer is required”
We reproduced on npm/Linux (Oct 31, 2026): 1.17.20 fails; moving to OpenCode v2 (@opencode/cli) recovers free models in our test.
Writeup: OpenCode "1.18.0 or newer is required to use the free tier": the fix, tested

OpenAI Agents SDK 0.24 + mcp 2.x: parallel MCP calls run serially
Four 3s tools → 12.1s wall time over streamable HTTP (Nov 4 repro, no API key).
Issue: MCPServerStreamableHttp serializes all requests on mcp 2.x, so parallel tool calls run one at a time · Issue #5474 · openai/openai-agents-python · GitHub

Why showcase this here
These are documentation + reproduction artifacts meant for builders debugging real tools — citations to upstream issues/PRs, commands you can re-run, and explicit “when NOT to use” notes. No affiliate links.
Upcoming
A terminal walkthrough of the Agents SDK #5474 break (What Broke This Week Episode 2) is scheduled for Friday Nov 6, 2026 at 5:00 AM PT on @lalipublications. No public video URL at post time; I can reply with it after publish if useful.
Happy to take technical questions or corrections in-thread.
