📦 OMP 18.8.0 — Breaking: the env API-key helpers (getEnvApiKey, getEnvApiKeyName, listProvidersWithEnvKey) are no longer exported from @oh-my-pi/pi-ai/stream — import from @oh-my-pi/pi-ai or @oh-my-pi/pi-ai/env-api-key — and TranscriptionRequest.audio now accepts Uint8Array | Blob, so consumers must handle Blob. Plus CPU/memory efficiency gains across streamed responses (Cursor, Devin, Codex, OpenAI Responses, GitLab Duo Workflow) and faster tool-output pruning/telemetry in long-running sessions.

📦 Cursor: Remote control for local agents — You can now see and reply to the local agents running on your computer from Cursor — remote control for agents that stay on your machine.

📦 Anthropic launches expanded Cyber Verification Program — The expanded CVP makes advanced cyber capabilities and reduced blocking classifiers available to qualifying security professionals, now organized into three access tiers that security teams can apply for.

Both harness items extend agent operation past the live session — Cursor adds remote see-and-reply for local agents, and OMP 18.8.0 improves tool-output pruning and telemetry capture during long-running sessions.

🚨 GitHub: Incident with Git Operations, Pull Requests and Actions — Incident spanned Git Operations, Pull Requests, and Actions, resolved after 71 minutes — re-check any Actions runs queued in that window.

🚨 Cursor: service degradation — Cloud Agents and Grok Bot — Service degradation affecting Cloud Agents and Grok Bot — Grok Bot was restored first while the Cloud Agents investigation continued; resolved after 159 minutes.

Both incidents are marked resolved — GitHub's Git Operations/Pull Requests/Actions incident after 71 minutes, Cursor's Cloud Agents and Grok Bot degradation after 159 — so the residue to check is Actions runs and Cloud Agent tasks that failed inside those windows, not a pending fix.
