Claude Code 2.1.101

What's changed

• Added /team-onboarding command to generate a teammate ramp-up guide from your local Claude Code usage
• Added OS CA certificate store trust by default, so enterprise TLS proxies work without extra setup (set CLAUDE_CODE_CERT_STORE=bundled to use only bundled CAs)
• /ultraplan and other remote-session features now auto-create a default cloud environment instead of requiring web setup first
• Improved brief mode to retry once when Claude responds with plain text instead of a structured message
• Improved focus mode: Claude now writes more self-contained summaries since it knows you only see its final message
• Improved tool-not-available errors to explain why and how to proceed when the model calls a tool that exists but isn't available in the current context
• Improved rate-limit retry messages to show which limit was hit and when it resets instead of an opaque seconds countdown
• Improved refusal error messages to include the API-provided explanation when available
• Improved claude -p --resume to accept session titles set via /rename or --name
• Improved settings resilience: an unrecognized hook event name in settings.json no longer causes the entire file to be ignored
• Improved plugin hooks from plugins force-enabled by managed settings to run when allowManagedHooksOnly is set
• Improved /plugin and claude plugin update to show a warning when the marketplace could not be refreshed, instead of silently reporting a stale version
• Improved plan mode to hide the "Refine with Ultraplan" option when the user's org or auth setup can't reach Claude Code on the web
• Improved beta tracing to honor OTEL_LOG_USER_PROMPTS, OTEL_LOG_TOOL_DETAILS, and OTEL_LOG_TOOL_CONTENT; sensitive span attributes are no longer emitted unless opted in
• Improved SDK query() to clean up subprocess and temp files when consumers break from for await or use await using
• Fixed a command injection vulnerability in the POSIX which fallback used by LSP binary detection
• Fixed a memory leak where long sessions retained dozens of historical copies of the message list in the virtual scroller
• Fixed --resume/--continue losing conversation context on large sessions when the loader anchored on a dead-end branch instead of the live conversation
• Fixed --resume chain recovery bridging into an unrelated subagent conversation when a subagent message landed near a main-chain write gap
• Fixed a crash on --resume when a persisted Edit/Write tool result was missing its file_path
• Fixed a hardcoded 5-minute request timeout that aborted slow backends (local LLMs, extended thinking, slow gateways) regardless of API_TIMEOUT_MS
• Fixed permissions.deny rules not overriding a PreToolUse hook's permissionDecision: "ask" — previously the hook could downgrade a deny into a prompt
• Fixed --setting-sources without user causing background cleanup to ignore cleanupPeriodDays and delete conversation history older than 30 days
• Fixed Bedrock SigV4 authentication failing with 403 when ANTHROPIC_AUTH_TOKEN, apiKeyHelper, or ANTHROPIC_CUSTOM_HEADERS set an Authorization header
• Fixed claude -w failing with "already exists" after a previous session's worktree cleanup left a stale directory
• Fixed subagents not inheriting MCP tools from dynamically-injected servers
• Fixed sub-agents running in isolated worktrees being denied Read/Edit access to files inside their own worktree
• Fixed sandboxed Bash commands failing with mktemp: No such file or directory after a fresh boot
• Fixed claude mcp serve tool calls failing with "Tool execution failed" in MCP clients that validate outputSchema
• Fixed RemoteTrigger tool's run action sending an empty body and being rejected by the server
• Fixed several /resume picker issues: narrow default view hiding sessions from other projects, unreachable preview on Windows Terminal, incorrect cwd in worktrees, session-not-found errors not surfacing in stderr, terminal title not being set, and resume hint overlapping the prompt input
• Fixed Grep tool ENOENT when the embedded ripgrep binary path becomes stale (VS Code extension auto-update, macOS App Translocation); now falls back to system rg and self-heals mid-session
• Fixed /btw writing a copy of the entire conversation to disk on every use
• Fixed /context Free space and Messages breakdown disagreeing with the header percentage
• Fixed several plugin issues: slash commands resolving to the wrong plugin with duplicate name: frontmatter, /plugin update failing with ENAMETOOLONG, Discover showing already-installed plugins, directory-source plugins loading from a stale version cache, and skills not honoring context: fork and agent frontmatter fields
• Fixed the /mcp menu offering OAuth-specific actions for MCP servers configured with headersHelper; Reconnect is now offered instead to re-invoke the helper script
• Fixed ctrl+], ctrl+\, and ctrl+^ keybindings not firing in terminals that send raw C0 control bytes (Terminal.app, default iTerm2, xterm)
• Fixed /login OAuth URL rendering with padding that prevented clean mouse selection
• Fixed rendering issues: flicker in non-fullscreen mode when content above the visible area changed, terminal scrollback being wiped during long sessions in non-fullscreen mode, and mouse-scroll escape sequences occasionally leaking into the prompt as text
• Fixed crash when settings.json env values are numbers instead of strings
• Fixed in-app settings writes (e.g. /add-dir --remember, /config) not refreshing the in-memory snapshot, preventing removed directories from being revoked mid-session
• Fixed custom keybindings (~/.claude/keybindings.json) not loading on Bedrock, Vertex, and other third-party providers
• Fixed claude --continue -p not correctly continuing sessions created by -p or the SDK
• Fixed several Remote Control issues: worktrees removed on session crash, connection failures not persisting in the transcript, spurious "Disconnected" indicator in brief mode for local sessions, and /remote-control failing over SSH when only CLAUDE_CODE_ORGANIZATION_UUID is set
• Fixed /insights sometimes omitting the report file link from its response
• [VSCode] Fixed the file attachment below the chat input not clearing when the last editor tab is closed
