Claude Code 2.1.139
Agent view (`claude agents`, Research Preview) is the marquee primitive: a single list of every Claude Code session — running, blocked on you, or done — which is exactly the cross-session fan-out monitoring surface a multi-agent orchestration test needs. Real feature release (agent view, `/goal`, two new hook fields, plugin details, subagent identity headers), but the bulk of the changelog (~40 of ~50 bullets) is bugfix hardening.

New primitives
agent view (claude agents)commandNew Research-Preview command and capability: a unified list of every Claude Code session (running, blocked-on-you, or done). The headline primitive for agent orchestration — the single control surface for monitoring a fan-out of sessions.
Added agent view (Research Preview): a single list of every Claude Code session — running, blocked on you, or done. Run `claude agents` to get started. See https://code.claude.com/docs/en/agent-view
/goal commandcommandNew command that sets a completion condition and keeps Claude working across turns until met; works in interactive, -p, and Remote Control with a live overlay panel. Directly relevant to autonomous per-agent persistence in orchestrated runs.
Added `/goal` command: set a completion condition and Claude keeps working across turns until it's met. Works in interactive, `-p`, and Remote Control. Shows live elapsed/turns/tokens as an overlay panel
/scroll-speed commandcommandNew command to tune mouse wheel scroll speed with a live preview.
Added `/scroll-speed` command to tune mouse wheel scroll speed with a live preview
claude plugin details <name>commandNew subcommand showing a plugin's component inventory and projected per-session token cost.
Added `claude plugin details <name>` to show a plugin's component inventory and projected per-session token cost
transcript view navigation shortcutscapabilityNew transcript-view keyboard navigation: `?` for shortcuts, `{`/`}` to jump between user prompts, `v` to toggle the shortcut panel.
Added transcript view navigation: `?` for keyboard shortcuts, `{`/`}` to jump between user prompts, `v` to toggle shortcut panel
hook args: string[] field (exec form)hookNew hook config field that spawns the command directly without a shell, so path placeholders never need quoting.
Added hook `args: string[]` field (exec form) that spawns the command directly without a shell, so path placeholders never need quoting
hook continueOnBlock config optionhookNew PostToolUse hook config option: set true to feed the hook's rejection reason back to Claude and continue the turn.
Added hook `continueOnBlock` config option for `PostToolUse` — set to `true` to feed the hook's rejection reason back to Claude and continue the turn
CLAUDE_PROJECT_DIR for MCP stdio servers + ${CLAUDE_PROJECT_DIR} in plugin configsenv-varNew surface: MCP stdio servers now receive CLAUDE_PROJECT_DIR in their environment (matching hooks), and plugin configs can interpolate ${CLAUDE_PROJECT_DIR} in commands. New env-var exposure and interpolation point, not a fix.
MCP stdio servers now receive `CLAUDE_PROJECT_DIR` in their environment, matching hooks. Plugin configs can reference `${CLAUDE_PROJECT_DIR}` in commands
subagent identity headers + OTEL attributescapabilityNew observability surface for orchestration: subagent API requests carry x-claude-code-agent-id / x-claude-code-parent-agent-id headers, and claude_code.llm_request OTEL spans include agent_id / parent_agent_id attributes — enabling parent/child agent tracing in a fan-out.
API requests from subagents now carry `x-claude-code-agent-id` / `x-claude-code-parent-agent-id` headers, and `claude_code.llm_request` OTEL spans include `agent_id` / `parent_agent_id` attributes
[VSCode] reopen-closed-session shortcut + claudeCode.enableReopenClosedSessionShortcutsettingNew VSCode keybinding (Cmd/Ctrl+Shift+T to reopen most recently closed session tab) plus a new setting to configure it.
[VSCode] Press Cmd/Ctrl+Shift+T to reopen the most recently closed session tab, configurable via `claudeCode.enableReopenClosedSessionShortcut`
Agentic relevance
This version pushes the agent-orchestration frontier through three new surfaces: agent view (`claude agents`) gives a single cross-session control plane for monitoring a fan-out of running/blocked/done agents, `/goal` gives each agent an autonomous completion condition that persists across turns, and subagent identity headers plus `agent_id`/`parent_agent_id` OTEL attributes make parent/child tracing observable in a fan-out. Together they convert multi-agent orchestration from an opaque batch into a monitorable, goal-driven, traceable system — while the new hook fields (`args`, `continueOnBlock`) and `CLAUDE_PROJECT_DIR` exposure tighten the control loop around each agent.
Hardening & fixes (40)
- Compaction prompt now asks the model to preserve sensitive user instructions
- `/mcp` Reconnect now picks up `.mcp.json` edits without a restart, and shows the HTTP status and URL when reconnecting fails
- `/context all` per-skill token estimates now account for the model's tokenizer and show rounded values
- `claude plugin install <name>@<marketplace>` now auto-refreshes the marketplace and retries before reporting a plugin as not found
- `/plugin` installed-plugin details now show hook event names and MCP server names cleanly
- `/context` now shows the providing plugin's name for plugin-sourced skills
- Remote MCP server reconnect retry on transient failures is now enabled for all users
- Remote Control, `/schedule`, claude.ai MCP connectors, and notification preferences are now disabled when `ANTHROPIC_API_KEY` / `apiKeyHelper` / `ANTHROPIC_AUTH_TOKEN` is set, even if a Claude.ai login also exists. Unset the API key to use these features
- Fixed a deadlock where expired credentials and the `forceRemoteSettingsRefresh` policy setting blocked `claude auth login`/`logout`/`status` with no way to recover
- Fixed `autoAllowBashIfSandboxed` not auto-approving commands with shell expansions like `$VAR` and `$(cmd)`
- Fixed a bug where a hook writing to the terminal could corrupt an on-screen interactive prompt; hooks now run without terminal access
- Fixed unbounded memory growth when an HTTP/SSE MCP server streams non-protocol data — response bodies now capped at 16 MB per SSE frame
- Fixed `Skill(name *)` permission rules — the wildcard form now works as a prefix match, matching `Bash(ls *)` behavior
- Fixed settings hot-reload not detecting edits to symlinked `~/.claude/settings.json`
- Fixed plugin details failing to load when the marketplace key differs from the manifest name
- Fixed `/model` picker "Default" row not reflecting `ANTHROPIC_DEFAULT_OPUS_MODEL`/`ANTHROPIC_DEFAULT_SONNET_MODEL` overrides
- Fixed spurious "stream idle timeout" 5 minutes after a response completed, caused by the watchdog timer not being cleared on stream cancellation
- Fixed silent `exit 1` when 10+ MCP servers are configured and the cache directory is unwritable — the error message now includes the underlying cause
- Fixed a typing cursor blinking on tab names, list pointers, and select rows in dialogs
- Fixed transcript view letter shortcuts not working after mouse click
- Fixed Bash-mode up-arrow history repeating the first entry and clobbering the in-progress draft
- Fixed pasting or dropping multiple images only inserting the last one
- Fixed hyperlinks using unreadable dark navy on dark themes — they now adapt to the active theme
- Fixed model picker showing a redundant "Current model" row for third-party users whose model is set to the `opus` alias
- Fixed legacy Opus picker entry on PAYG 3P providers resolving to the same model as the default entry
- Fixed mouse wheel scrolling speed in Cursor and VS Code 1.92–1.104; the trackpad now scrolls at a steady rate and the mouse wheel keeps ~3 lines per notch
- Fixed scroll behavior in Windows Terminal and VS Code when attached to background sessions
- Fixed MCP resources from disconnected servers lingering in `@server:` autocomplete
- Fixed two-file diff snippets over-reporting the number of truncated lines by one
- Fixed Grep results not relativizing Windows drive-letter paths and count mode reporting wrong totals for single-file paths
- Fixed border-embedded text overflowing on CJK/emoji due to visual cell width miscalculation
- Fixed fuzzy-match highlighting splitting emoji and astral-plane characters mid-pair
- Fixed skill argument names containing regex metacharacters breaking argument substitution
- Fixed ProgressBar rendering a full block for an almost-full fractional cell
- Fixed task polling and `fs.watch` being resurrected when the last subscriber leaves while a fetch is in flight
- Fixed plugin dependency resolution leaving a stale count when the manifest name differs from the source identifier
- Fixed Insights Time-of-Day chart skewing when a session has an unparseable timestamp
- Fixed keybindings using only the cmd/super/win modifier being flagged as unparseable
- Fixed `claude_code.active_time.total` OpenTelemetry metric not being emitted in `--print` mode
- Fixed `claude plugin update` not preserving cross-plugin symlinks inside a marketplace
