Freeze

Restricts all Edit and Write tool calls to a single directory for the current session, preventing accidental changes outside the intended scope.

Purpose

Activate a directory lock that blocks any Edit or Write operation targeting files outside the specified path — useful when debugging, doing a scoped refactor, or working in one module and wanting to avoid accidentally touching unrelated code.

Trigger

Apply when user requests:

• "freeze", "freeze edits", "lock edits to this directory", "restrict to directory"
• "scope edits", "only edit this folder", "鎖定編輯範圍", "只能改這個目錄"
• Automatically activates as part of guard (which combines careful + freeze)

Do NOT trigger for:

• Read operations — freeze never restricts reads, only writes
• Cases where work genuinely spans multiple directories — ask the user to confirm before freezing
