Releases v2.1.139 → v2.1.1423 features · May 11–15
Agent viewresearch preview

claude agents opens one screen for every Claude Code session: what’s running, what’s blocked on your input, and what’s done. Dispatch a bug fix, a pull request review, and a flaky-test investigation as three rows, keep working in another window, and step in only when a row needs you. Attach to any row to drop into its full conversation, then press ← to return to the list. Each background session keeps running without a terminal attached.

Open the dashboard from your shell:

terminal
claude agents
Agent view
/goalv2.1.139

Set a completion condition and Claude keeps working toward it across turns without you prompting each step. After every turn, a fast model checks whether the condition holds; if not, Claude starts another turn instead of handing control back. Useful for substantial work with a verifiable end state, like migrating a module until every call site compiles and tests pass. The goal clears once the condition is met, and works in interactive, -p, and Remote Control.

Set a goal and let Claude run until it holds:

Fast mode on Opus 4.7research preview

/fast now runs on Opus 4.7 by default instead of Opus 4.6. Fast mode is a high-speed Opus configuration: the same model quality at about 2.5x the speed for a higher per-token cost, useful for rapid iteration and live debugging. Pricing is unchanged at 30/30/150 per MTok, the same as Opus 4.6 fast mode. To pin fast mode to Opus 4.6, set CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE=1.

Other wins

claude agents gained dispatch flags (—add-dir, —settings, —mcp-config, —plugin-dir, —permission-mode, —model, —effort, —dangerously-skip-permissions) to configure background sessions, and claude agents —cwd <path> scopes the session list to a directory
New hook args: string[] exec form spawns the command directly without a shell, so path placeholders never need quoting
New continueOnBlock config option for PostToolUse hooks feeds the hook’s rejection reason back to Claude and continues the turn instead of ending it
New terminalSequence field in hook JSON output lets hooks emit desktop notifications, window titles, and bells without a controlling terminal
The Rewind menu added “Summarize up to here” to compress earlier context while keeping recent turns intact
Remote Control, /schedule, Claude.ai MCP connectors, and notification preferences are now disabled when ANTHROPIC_API_KEY, apiKeyHelper, or ANTHROPIC_AUTH_TOKEN is set, even alongside a Claude.ai login; unset the API key to use these features
MCP stdio servers now receive CLAUDE_PROJECT_DIR in their environment, matching hooks, and plugin configs can reference $CLAUDE_PROJECT_DIR in commands
claude plugin details <name> shows a plugin’s component inventory and projected per-session token cost, and the /plugin details pane now also lists the LSP servers a plugin provides
Plugins with a root-level SKILL.md and no skills/ subdirectory are now surfaced as a skill
/feedback can now include recent sessions from the last 24 hours or 7 days for issues spanning more than the current session
Agent tool subagent_type now matches case- and separator-insensitively, so “Code Reviewer” resolves to code-reviewer
