Auto mode groundwork for reviewing computer-use and browser actions

What

Auto mode lets Claude act without asking each time, using a classifier, a model that judges each action. Computer use means Claude controlling a desktop by clicking and typing. New code, controlled by server-side switches, prepares closer review of these actions and of browser actions.

• Allow rules: when the check is on, a computer-use action that changes something (not an observe or access action, and not a served call) is no longer approved straight away by an allow rule for the whole tool, and the shortcut that skips further checks is suppressed. The action goes on through the rest of the permission checks.
• Classifier routing: computer-use calls can be kept out of the "would be allowed in acceptEdits" and "safe allowlist" shortcuts so the classifier judges them. The skip for calls that come from a plugin no longer applies to certain tool names.
• The check is on when tengu_quirky_shore is "on" (fallback "off") or the computerUseChecks key is true in the tengu_drifting_reef settings object.
• Action summaries: the Chrome computer and form_input tools, browser_batch items and computer-use tools can gain an action_summary field asking Claude for a few words on what each action does, for example "Sets the delivery date to 29 September". The field asks for the effect only, with no reasons and no passwords or other secrets.
• For Chrome this is switched on by chromeAgentNote in tengu_auto_mode_config or the browserSummary key of tengu_drifting_reef. For computer use, by computerUseAgentNote or the computerUseSummary key.
• The classifier's records gain fields for these computer-use and summary details.

Nothing has been read about tengu_quirky_shore or tengu_drifting_reef for this release, and no reading of tengu_auto_mode_config has been taken under it.

Why

When switched on, clicks and typing in auto mode would be checked even if you allow-listed the whole computer-use tool, and short summaries would give a readable line for each browser or desktop action. Until the switches are on, behaviour may not change.
