docs: Claude Code v2.1.270 - cloud session monitoring, effort defaults, computer-use fixes

[claude-yolo]

Night shift report

WHY THIS MATTERS: This batch of Claude Code docs updates removes /tasks as the recommended way to monitor cloud sessions (users are now pointed to the web UI and mobile app instead), clarifies how the effort parameter default actually works in the Agent SDK (it's undefined, not "model default" — meaning Claude Code's own resolution order takes over, not the model's default), and fixes two computer-use behavioral descriptions. The teleport error table also gets a version annotation noting the pre-v2.1.219 behavior. The bulk of the diff (67 files) is support article image URL refreshes — pure noise.

HIGHLIGHTS:

• /tasks removed from cloud session monitoring docs — claude-code-on-the-web.md drops two references telling users to run /tasks to check session progress; the docs now send users to claude.ai or the mobile app directly. If /tasks was removed from the CLI or deprecated for cloud sessions, this is the paper trail.
• Agent SDK effort default clarified — both agent-loop.md and typescript.md now say the default is undefined and "Claude Code resolves the effort level itself" per the model-config resolution order, replacing the vaguer "model default" / "defer to the model's default behavior." SDK authors who were relying on the old phrasing to infer behavior should re-read the model-config resolution docs.
• Computer-use notification fires per-turn, not per-lock — the "Claude is using your computer" macOS notification description changed from "when Claude acquires the lock" to "the first time Claude uses your computer in each turn." This matches a behavioral fix: the notification was apparently firing at lock acquisition rather than at first action each turn.
• Teleport error message improvement noted — the requirements table now documents that before v2.1.219, the teleport mismatch error didn't name your local checkout's repository. Low-stakes but useful for users on older versions.
• error_during_execution example trimmed — "API failure" was removed from the example list; only "cancelled request" remains. Possibly reflects that API failures are now handled differently (retried?).
• Support article churn (67 files) is CDN image URL refreshes — no editorial content changed.
