What's changed

/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
Skills and slash commands can now set disallowed-tools in frontmatter to remove tools from the model while the skill is active
Added /reload-skills command to re-scan skill directories without restarting the session
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
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
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
Added the session entrypoint as an OpenTelemetry metric attribute (app.entrypoint, opt-in via OTEL_METRICS_INCLUDE_ENTRYPOINT=true)
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
