Claude Code provider

Read settings with bb plugin config provider-claude-code; change a declared key with bb plugin config provider-claude-code set <key> <value>.

• disable1MContext defaults to false. Enable with bb plugin config provider-claude-code set disable1MContext true to set CLAUDE_CODE_DISABLE_1M_CONTEXT=1 (0 when off). Changes restart the thread's Claude process before its next turn, preserving context.
• chromeEnabled defaults to false. It starts Claude Code with --chrome for Claude in Chrome tools. The host needs the extension and a claude.ai login. A change restarts the thread's Claude process before its next turn, preserving context.
• Select the Fast service tier in the model picker or pass --service-tier fast to bb thread spawn for supported Opus models. Use bb thread tell --service-tier fast to change a thread on its next turn; default turns it off. Fast mode requires eligible Claude access; subscription accounts need usage credits. It is billed at premium rates. The provider passes the selection as a session-scoped SDK setting, so it does not change the user's Claude defaults.
• sandboxEnabled defaults to true. In Accept Edits and Approve for me modes bb runs Claude Code's Bash commands in its sandbox. Set it to false to use Claude Code's own command approvals and sandbox settings instead. A change restarts the thread's Claude process before its next turn, preserving context.
• bb passes only BB_CLAUDE_CODE_EXECUTABLE and CLAUDE_CODE_OAUTH_TOKEN to the CLI. Mint the token with claude setup-token for machines with no interactive login.
• Structured plan, message editing, and compaction are supported through the corresponding bb thread commands. Unlisted model IDs are accepted by the provider; verify actual availability on the target host.

Inspect the thread and provider state after a change; do not restart unrelated threads or change settings merely to answer a question.
