Claude Code 2.1.152

This release significantly boosts developer productivity with the direct application of code review suggestions to your working tree via /code-review --fix and /simplify. New capabilities offer dynamic control over tool availability within skills, session title customization, and enhanced hooks for skill reloading or assistant message transformation. The user experience is more reliable with automatic fallback models and clearer user interface feedback, including improved thinking displays and detailed background process reporting. Extensive fixes address session stability, plugin update reliability, and various UI display inconsistencies, providing a more robust and responsive environment for all users and skill creators.

Added

  • Added `/reload-skills` command to re-scan skill directories without restarting the session
  • Added a `MessageDisplay` hook event that lets hooks transform or hide assistant message text as it is displayed
  • Added `pluginSuggestionMarketplaces` managed setting: admins can allowlist org marketplaces whose plugins may be suggested via context-aware tips
  • Added the session entrypoint as an OpenTelemetry metric attribute (`app.entrypoint`, opt-in via `OTEL_METRICS_INCLUDE_ENTRYPOINT=true`)

Changed

  • Skills and slash commands can now set `disallowed-tools` in frontmatter to remove tools from the model while the skill is active
  • `SessionStart` hooks can now return `reloadSkills: true` to re-scan skill directories, making skills installed by the hook available in the same session
  • `SessionStart` hooks can now set the session title via `hookSpecificOutput.sessionTitle` on startup and resume
  • `claude plugin marketplace remove` now accepts `--scope user|project|local` for symmetry with `marketplace add`, `install`, and `uninstall`
  • Claude Code now switches to your configured `--fallback-model` for the rest of the session when the primary model is not found, instead of failing every request
  • Auto mode no longer requires opt-in consent
  • Vim mode: `/` in NORMAL mode now opens reverse history search (like Ctrl+R), matching bash/zsh vi-mode
  • The `/usage` breakdown now includes large session files; files are scanned with a streaming read so memory usage stays flat
  • Thinking summaries in the collapsed group now stay readable for at least 3 seconds, render as markdown, and cap at 10 lines (`Ctrl+O` shows the full thinking)
  • In fullscreen mode, the "Thinking for Ns" indicator now counts up live while the model is thinking, and keeps its value if you interrupt mid-thought
  • Simplified the Workflow tool's inline progress display — live agent counts now show only in the persistent workflow status row below the prompt
  • The post-response timer now shows "Waiting for N background agents/workflows to finish" when backgrounded agents or workflows are still running, and reports the cumulative time once their results are processed

Fixed

  • `/code-review --fix` now applies review findings to your working tree after the review, surfacing reuse, simplification, and efficiency suggestions; `/simplify` now invokes `/code-review --fix`
  • Fixed terminal styling degrading in very long sessions by recycling the renderer's style pool
  • Fixed the sandbox-enabled warning not appearing in condensed startup mode — it now shows in every layout
  • Fixed the loading spinner showing "still thinking"/"almost done thinking" while a tool is running, and reset the thinking status to "thinking" after each tool
  • Fixed focus mode showing a spurious "N messages hidden" count on turns with no hidden activity
  • Fixed clicking a link inside an expanded tool result collapsing the section instead of opening the link
  • Fixed markdown table cell borders inheriting the color of inline code, wrapped continuation lines losing their style, and empty header cells showing a label in the narrow-terminal stacked layout
  • Fixed plugin MCP servers with the same command but different environment variables being incorrectly deduplicated
  • Fixed `/doctor` reporting "marketplace not found" or "plugin not found" for stale `enabledPlugins` entries referencing removed marketplaces or dropped plugins
  • Fixed plugins that track a git branch silently no longer receiving updates after the plugin registry was rebuilt
  • Fixed remote MCP servers failing to connect in Claude Code Remote sessions when the egress proxy is enabled
  • Fixed the effort-change confirmation dialog appearing when the conversation has no messages or when switching between effort levels that resolve to the same underlying value
  • Fixed the Agent tool description referencing an agent list that is never delivered when running with `--bare` or with attachments disabled
  • Fixed a background worker crash in `claude agents` when accepting a stale permission prompt after a subagent was cancelled
  • Fixed `cache_creation_input_tokens` reporting as 0 in transcript and result usage when the API reports cache writes only via the nested `cache_creation` breakdown
  • Fixed the PushNotification tool incorrectly reporting "Mobile push not sent (Remote Control inactive)" in SDK-hosted sessions when Remote Control is enabled
  • Fixed sessions getting stuck after a model or login switch left stale thinking-block signatures in history; now stripped proactively with a retry safety-net
