Claude Code 2.1.223

This release adds marketplace filtering via owner wildcards, improves permission and security controls including fixes for Bash permission bypasses and sandbox escapes, enhances model discovery and overrides handling, and refines session management and command review workflows.

  • Added owner wildcard entries ("owner/*") to the strictKnownMarketplaces and blockedMarketplaces managed settings for allowing or blocking all marketplace repos under a GitHub org
  • Added a warning when workflow agents, forked skills, slash commands, or resumed background agents' requested subagent model is restricted and the parent model runs instead
  • Added a /teleport hint in cloud sessions showing how to continue locally with claude --teleport <session id>
  • Fixed a Bash permission bypass where a crafted command could hide parts of itself from permission checks
  • Fixed permission prompts so commands padded with tabs or invisible Unicode can no longer hide part of the command from the approval dialog
  • Fixed workflow scripts being able to use dynamic import() to run code outside the workflow sandbox
  • Fixed a permission gap where an agent definition's bypassPermissions mode ignored the org bypass-permissions disable policy
  • Fixed resuming a session after a mid-session /cd coming back empty
  • Fixed gateway model discovery hiding Claude models registered under provider-prefixed IDs such as vertex_ai/claude-* or bedrock/anthropic.claude-*
  • Fixed modelOverrides keys that aren't Anthropic model IDs being treated as the session's canonical model ID; unknown keys are now ignored as documented
  • Fixed managed settings: server-delivered settings no longer disable the env block of a machine-local managed-settings.json or MDM profile; admin env now merges per key
  • Fixed sandboxed commands failing to start on Linux when sandbox.filesystem.denyWrite covers the working directory
  • Fixed forked background agents getting stuck "already resuming" for the rest of the session when rebuilding the fork's parent prompt failed during resume
  • Fixed a resumed session failing every turn, or leaving the interactive app on an unresponsive error screen, when its history held a malformed diagnostics attachment
  • Fixed a rare hang when parsing unusual git push output
  • Changed CLAUDE_CODE_DISABLE_1M_CONTEXT to hold every Claude model with a native 1M window to 200K via auto-compaction, not just a fixed list; a startup warning now appears when auto-compaction isn't holding the session to 200K
  • Changed auto-compact to keep sessions on unrecognized model IDs within the assumed context window instead of letting them grow past it; set CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1 to restore the previous behavior
  • Changed /review to be an alias of /code-review, which reviews the current diff or a PR (/code-review <level> <pr#>); use /code-review ultra for a deep cloud review
  • Changed /code-review with no effort level to reuse the level you typed last; type a level like /code-review high to change it
