7. Feishu / Lark CLI Operator

Route Feishu/Lark work through the official lark-cli — Docs, Drive, Base, Sheets, Wiki — and diagnose custom Base Block errors as the tenant-identity problems they usually are.

Features:

• User vs. bot identity baselines, including the --no-wait / --device-code login flow for agent harnesses
• Intent → command routing paired with the CLI's embedded, version-matched guides
• High-risk-write contract: exit 10 + confirmation_required means ask, never auto---yes
• Dry-run diff technique for telling honoured flags from silently ignored ones
• Version-independent wrapper for when a Node upgrade breaks the global shim

Use Cases:

• Searching and editing Feishu Docs safely from the command line
