Claude Code 2.1.248
- Added `--restricted` (or `CLAUDE_CODE_RESTRICTED=1`): removes the built-in tools that run commands or code and `WebFetch` (unless named in `--tools`), keeps file tools inside the working directory, refuses `bypassPermissions`, and ignores user, project and local settings files - Added `experimental.cacheTtl` (`"5m"` or `"1h"`) to agent frontmatter: a per-agent prompt cache TTL used when no subagent TTL setting is configured - Added `claude self-hosted-runner --client-label <label>` (or `SELF_HOSTED_RUNNER_CLIENT_LABEL`) to override the label the runner registers with (default: hostname) - Added server-managed settings diagnostics: a startup warning when the settings fail to load, and a `/doctor` and `/status` line explaining a load failure or why they weren't fetched (Bedrock/Vertex/third-party provider, custom `ANTHROPIC_BASE_URL`) - Added a warning in `/web-setup` when the GitHub CLI token lacks the `workflow` scope, since pushes to very large repositories can be rejected without it - Added `/usage-credits` for Enterprise organizations billed through AWS Marketplace, self-serve Enterprise, and Enterprise trials, so members can request a higher usage limit from their admin - Added cross-session messaging (`SendMessage` / `ListAgents`) between sessions on the same machine on Bedrock, Vertex, and Foundry, and when telemetry is disabled - Fixed a prompt-cache miss (and lost extended-thinking context) roughly once an hour in long sessions, caused by tool definitions being re-r
