This week on kalauz

autowt v0.6.0 rewritten in Go; claims 30ms overhead vs. 200ms in Python (irskep/autowt GitHub releases, 2026-06-11). Performance-focused rewrite suggests rival is optimizing for speed in the worktree-manager space.

The move: Performance is table stakes for editor-native workflows. Validate your session startup and command latency against 30ms baseline; if you're slower, the wedge erodes. If faster, lead with that in positioning.

Claude Squad v1.0.18 shipped UI event loop fixes and instance reorder (Shift+J/K) — github.com/smtg-ai/claude-squad. v1.0.17 added source branch selection for sessions and preset profile config.

The move: Claude Squad is tightening session UX (reorder, branch control, profiles). Double down on git-native worktree persistence as the differentiator — your wedge is the *layer*, not the UI chrome. Make session state portable across tools; let them own the reorder.

v1.0.19 is a version bump only (2026-06-17); no feature changelog. Suggests either a quiet release cycle or internal stabilization.

The move: Watch for a feature drop in the next tagged release. If it lands session sync or cross-tool state, that's a direct wedge play — move fast on interop.

Windsurf Visual Studio v1.6.13 (Dec 2023) shipped chat window theming fixes, inline diff UX polish, and SDK downgrade. Source: Exafunction/WindsurfVisualStudio GitHub releases.

The move: No action — routine maintenance on a VS Code-bound tool outside the git-native worktree layer.

Streaming fix (incomplete in release notes).

The move: No action until full details surface.

battysh/batty v0.11.63 and v0.11.62 released — docs refresh and launch-stability fixes for daemon detection, work status, and Discord config (GitHub releases, 2026-04-25).

The move: No signal against the wedge. Batty is a task-dispatch and daemon-control system, orthogonal to git-native worktree session management in your editor.

v2.7.2 validation notes mention shellcheck and git diff --check — routine CI/linting, no feature signal.

The move: Noise. File and move on.

Claude Code v2.1.199 shipped stacked slash-skill invocations (up to 5 skills in one command) and SSL/TLS error handling improvements (anthropics/claude-code GitHub releases, 2026-07-02).

The move: Monitor skill composition patterns in your session persistence layer — if users chain skills across worktrees, your git-native layer may need to track skill state across parallel sessions.

Codex released rust-v0.143.0-alpha.35 and alpha.34 (July 2–3, 2026). No changelog details provided in the GitHub releases.

The move: File and monitor. Without specifics on what shipped, no signal on whether this touches the worktree layer, session persistence, or editor integration. Resume tracking when release notes clarify the delta.

autowt v0.6.0-rc cycle (rc3–rc5) shows active iteration and stabilization, no feature announcements in the visible notes.

The move: Monitor for feature parity or new capabilities in the stable release; rc churn alone is not a signal.

git-worktree-manager v3.25.0 added sorting by time in branch picker; v3.24.2 added last commit time display on worktree items (GitHub jackiotyu/git-worktree-manager).

The move: Rival is iterating on UX polish—time-based sorting and visibility. Your wedge owns the session layer and editor integration; stay focused on persistence and parallel session management rather than competing on picker UX.

Agent Deck v1.9.73 released (June 21, 2026) as a terminal session manager for AI coding agents, bundling fixes from v1.9.70–v1.9.72 including a UTF-8 locale handling fix (GitHub: asheshgoplani/agent-deck).

The move: Agent Deck remains a terminal-first tool; your wedge is editor-native with git worktree persistence across parallel sessions. No direct threat to the positioning — continue building the in-editor, multi-session layer that Deck doesn't own.

CodeRabbit's git-worktree-runner v2.8.0 added `git gtr clean --closed` to remove worktrees for closed (unmerged) PRs/MRs, with filtering by target base ref (GitHub #183). v2.7.3 fixed nested registered worktree detection; v2.7.2 optimized directory copy performance by skipping excluded subtrees upfront.

The move: These are incremental UX and performance refinements to a worktree cleanup/inventory tool — not a shift in capability or positioning. Monitor if CodeRabbit ships session persistence or editor integration; that would signal a move into your wedge.

Claude Squad v1.0.17–v1.0.19 (Mar–Jun 2026): Added source branch selection for sessions, preset profile configuration, instance reorder (Shift+J/K), UI event loop optimization, and completion script fixes. Source: github.com/smtg-ai/claude-squad/releases

The move: Claude Squad remains a multi-session orchestrator but shows no shift toward git-native worktree persistence or editor-native integration. Continue tracking for any pivot toward session state durability across editor restarts or worktree-aware branching.

tmux released 3.7, 3.7a, and 3.7b (bug fix releases) in June–July 2026. Standard maintenance cadence with no announced feature surface.

The move: No action. tmux remains a terminal multiplexer; it does not compete with the git-native worktree layer or AI coding session persistence.
