Claude Code v2.1.223

What's changed

• 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
