What's changed

Added a live elapsed-time counter to the collapsed tool summary line so long-running tool calls visibly tick instead of looking stuck

Added a startup warning for Write(path), NotebookEdit(path), and Glob(path) permission rules — use Edit(path) or Read(path) instead

Fixed isolation: 'worktree' subagents being able to run git-mutating commands against the main repo checkout instead of their own isolated worktree

Fixed the ultracode keyword opt-in firing on non-human-originated input such as webhook payloads and relayed PR comments

Fixed a rendered text fragment leaking into crash telemetry when a UI component returned content outside a styled text element

Fixed paste markers leaking into external editors opened from Claude Code, which could appear as stray È/É characters around pasted text

Fixed claude attach sometimes failing with "job not found" or "agent is still starting" errors during session transitions — attach now waits for the daemon to settle, and terminal resizes during a slow attach are applied once it completes

Fixed a session crash when a tool's result renderer returned a numeric bigint value or plain text instead of a UI element

Fixed a hook callback timeout being misreported to the model as a user rejection, which made unattended sessions stop and wait

Fixed Claude assuming a cd took effect after its command was moved to the background; the tool result now states the working directory is unchanged

Fixed plugin-provided MCP servers being torn down when MCP servers are re-synced mid-session

Fixed plan approvals without edits being labeled "(edited by user)" and overwriting the plan file with a stale snapshot

Fixed /doctor skipping its auto-mode-default proposal on Bedrock, Vertex, and Foundry, where auto mode no longer needs an opt-in

Fixed Grep content mode claiming "No matches found" when paginating past the end of results

Fixed unmatched $1/$2 positional placeholders in skills and commands being silently stripped; they are now preserved verbatim

Fixed plugin cache writes leaving temp files behind on failure and failing on locked-file renames on Windows and network filesystems

Fixed background workers crash-looping when a client resets its connection to the background service

Fixed claude agents --effort ultracode not reaching dispatched sessions; the value was silently dropped

Fixed pressing ← to open the agents view dropping the task tracker when returning to the session

Fixed the agents dashboard retaining pasted images from abandoned reply drafts after their session was deleted

Fixed killed background sessions leaving a permanent git worktree lock behind; the periodic sweep now releases locks whose owning process is gone

Fixed SDK MCP servers registered via an initialize control request waiting until the next turn to start connecting

Fixed returning to the agents view from a session leaving overlapping ghost frames with CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1

Fixed late-appearing .claude/* symlinks not being reconciled into the sandbox deny-write list

Hardened the Agent tool against indirect prompt injection via content a subagent read

Improved the Bash/PowerShell tool message when a command hits its timeout and is auto-backgrounded, so the model can distinguish a hang from an explicit background request

Improved auto mode: the permission classifier now defaults to Sonnet 5 for external sessions, validated on the session's first request and pinned for the session

Improved the bundled dataviz skill's chart color validation with perceptual OKLab color difference and recalibrated color-blindness thresholds

Memory writes that leave a MEMORY.md index over its read limit now produce an explicit error instead of silent truncation

Screen reader mode now announces permission mode changes aloud when cycling modes with Shift+Tab

The agents footer hint now shows how many background agents are waiting on your input, with a brief color emphasis when the count changes

Agent view: the session you pressed ← from stays visibly marked even after mouse hover or arrow keys move the selection

Fable temporarily shows as unavailable in the advisor picker while a server-side issue causing Fable advisor failures is fixed
