Claude Code v2.1.81: --bare Flag for Headless Scripting + Mobile Permission Relay via --channels
Releasebot·high signal
Version 2.1.81 (March 21) adds a --bare flag for scripted -p calls that skips hooks, LSP, plugin sync, and skill directory walks — requires ANTHROPIC_API_KEY or apiKeyHelper (OAuth and keychain disabled). The --channels permission relay enables two-way channel servers to forward tool approval prompts to a second device in parallel with the local terminal dialog; first answer wins. Also fixes OAuth token refresh failures for multiple concurrent sessions and resolves special-character bash command parsing.
