Copilot cloud sessions and Automations: persistent agent sessions, cross-device continuity, and self-improving automations

What changed: GitHub rolled out a connected Copilot cloud experience so cloud agent sessions persist across web, mobile, app, CLI and IDEs starting Oct. 28, 2026. Copilot Automations can now run in the cloud and learn from outcomes, surfacing suggested improvements that teams can approve or reject.

Why it matters: Engineers and operators can let agent work continue off-host (useful for long-running refactors or batch tasks) while keeping human checkpoints; teams can convert repetitive workflows into cloud automations that self-improve but still require explicit approvals to change behavior.

Try/watch: Enable cloud sessions in a staging project, require human approvals for any automation that modifies production-facing code, and log automation suggestions to measure how often the “self-improvements” reduce manual work versus introducing noisy or risky changes.

Snowflake adds explicit reasoning controls, extra system instructions, and stage mounts for its Cortex coding agents

What changed: Snowflake’s documentation shows a Oct. 28, 2026 update to Cortex Agents’ coding API that adds three public controls: a thinking_effort param to tune orchestration-model reasoning effort, instructions.system to append system-level directions, and stage_mounts to mount versioned Snowflake stages into the agent’s sandboxed runtime.

Why it matters: For teams using data-aware coding agents, these controls let operators balance speed vs. depth of reasoning, provide safer system-level constraints without editing the core sandbox, and give agents direct, versioned access to notebooks, apps, or datasets inside the environment they already use — reducing context-mismatch and fragile file-copy flows.

Try/watch: Use thinking_effort to run the same integration task at two levels (e.g., medium vs high) and compare correctness, latency, and token usage; mount a read-only stage with test data to validate reproducible agent runs before giving agents write access.
