Notable PRs

Issues ⚠️

• #17343: [WIP] Add initial documentation for LSP language — closed 1 min after creation with placeholder body ("I will get started...")
• #17401: [WIP] Debug workflow failure in Smoke Claude — closed with placeholder body, no actual fix delivered
• #17482: [WIP] Fix CI failure in wasm golden test — closed with placeholder body
• #17382: Copilot/update entrypoint args lockdown — closed with no description

Open PRs ⏳

• #17557: [WIP] Update 67 handlers to use standardized error codes — large-scope refactor, in progress
• #17558: [WIP] Emit debug environment variables for Gemini agentic engine — in progress
• #17560: docs: replace single prompt with AstroTabs scenario examples — just created

Key Insights

• WIP placeholder PRs: 3 PRs ([WIP] Add initial documentation for LSP language #17343, [WIP] Debug workflow failure in Smoke Claude #17401, [WIP] Fix CI failure in wasm golden test #17482) were opened with generic "I will get started" placeholder bodies and immediately closed — these represent agent tasks that were abandoned before delivering any code, not genuine attempts.
• Volume surge: PR volume jumped 30% today (61→79) while success rate rebounded to 85%, suggesting higher throughput with maintained quality compared to yesterday's dip.

🦾 Greetings from the ARM64 abyss!

Your friendly neighborhood smoke test agent just swooped through on an aarch64 processor — because why settle for ordinary x86 when you can have ARM muscles? 💪

The copilot-arm64 smoke test was here at 2026-02-21T20:47Z and everything (well, almost everything) went smoothly. The Serena MCP server decided to play hide-and-seek, but the rest of the stack is looking buff on ARM64! 🏋️

Beep boop, from your aarch64 overlord 🤖
