Claude Code 2.1.178

A few small interface and reporting improvements. /doctor (the health-check feature) now uses a consistent flat tree (flat tree, an unindented, flattened-out tree diagram) layout across every section, with clearer status icons and highlighted command names. When the skill list gets too long and is truncated, the truncation warning now tells you exactly how many skill descriptions are affected. The workflow (workflow, a predefined multi-step task) trigger keyword now glows with a purple shimmer, and only fires on explicit phrases like "run a workflow" or "workflow:" — not on any casual mention of the word. Finally, /bug (the bug-report feature) now requires a description before submitting, and no longer uses the model's refusal text as the GitHub issue title. Like a hospital health-check report switching to a clear tree layout, an emergency button that only arms on a specific code getting more visible, and a complaint form that no longer accepts just the three words "it's broken."

A batch of authorization issues that left you disconnected or crashed are fixed. The CLI (command-line interface) used to crash from running out of memory if it inherited a stale websocket/OAuth file-descriptor (file-descriptor, the number a program uses to access a file or connection) environment variable from its parent process (the program that launched it); it survives now. Claude in Chrome (the browser edition) used to silently fail to connect when the OAuth token belonged to a different account than the Claude Code login; it handles that properly now. claude agents workers (the child processes that do the work) used to fail with "401 Invalid bearer token" when the daemon (a program that stays resident in the background) had been started from a shell with a custom API gateway (API gateway, a self-hosted API endpoint) via ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN; that's fixed. Also, compaction (the feature that summarizes and shrinks old conversation) used to ignore --fallback-model (a fallback model, the lesser model it falls back to when the main one is swamped); it now follows the configured fallback chain on overload or model-availability errors. And when credentials (the keys proving you're a legitimate user) were refreshed outside the session, the app used to keep failing with auth errors due to a stale cached request config; it updates now. Like a company where one employee's expired badge used to crash the whole floor's systems, a misaddressed delivery was silently dumped, and the backup-staff system existed in name only — now an expired badge can't take the system down, packages are only accepted at the right address, and backups actually show up to work.

This batch fixes a pile of issues around viewing subagents, background tasks, and environment config. Viewing a subagent's (an agent Claude splits off for small chores) transcript (the verbatim full conversation) now shows tool results and live progress; messages you sent while it was still finishing its turn used to get dropped, and now they're kept; and backgrounding a running subagent with ctrl+b used to restart it from scratch, and now it keeps going as-is. Background sessions created with /bg or ←← after a turn used to read "Working" forever in the agents list; their status updates now. On Linux, the sandbox (the mechanism that traps a program in a restricted zone) used to fail to start when .claude/skills or .claude/hooks was a symlink (a file pointing elsewhere, like a shortcut); it starts fine now. The environment variable CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURE=1 (a switch to preserve the plugin marketplace on failure) used to actually block fresh marketplace installs from cloning; that's fixed. And MCP server-level rules (mcp__server, mcp__server__*, mcp__*) written in a subagent's disallowedTools (the forbidden-tools list) used to be silently ignored — as if you'd never set them — and now they take effect. Like a department where delegated progress used to be invisible, shelved projects glowed "in progress" forever, and certain badges and procurement settings were dead letters; now progress is transparent, status is honest, and the rules actually stick.

Three small keyboard-related bugs are fixed. In vim mode (vim, an editor style built around not touching the mouse), pressing u to undo (undo, retracting a just-made action) used to merge several consecutive actions into a single undo — so one press wiped out a whole chunk; it now steps back one NORMAL/VISUAL-mode command at a time. In the claude agents view, statusline (statusline, the row showing status at the bottom) links using a custom URI scheme (a self-defined web-address protocol like vscode://) used to do nothing when clicked; they open now. And in the VSCode extension, pressing Esc to dismiss a CJK IME (CJK IME, the little candidate window that pops up when typing Chinese/Japanese/Korean) candidate window used to also cancel the Claude task currently running; it no longer does. Like a typewriter whose backspace key used to gobble a whole sentence at once, a sticky-note link on your desk that wouldn't peel off, and dismissing an input-method reminder accidentally canceling a document mid-print — now backspace eats one character, the note peels, and dismissing the reminder leaves the print job alone.
