Worktree Engine — Parallel Tasks, Live Agent View & PR Import

Each task now runs in its own git worktree, unlocking real parallel execution. A new Agent tab streams Claude's output live, existing PRs can be imported as tasks, and the auto-reply loop now addresses every kind of PR comment.

Agent tab streaming live Claude CLI output during a task run

Features

Worktree engine — every task executes in an isolated git worktree, so concurrent runs no longer step on each other's branch state
Parallel task execution — run up to 10 tasks at once (default 5), configurable in Settings → General. Scans count against the same pool so Claude CLI is never over-subscribed
Agent tab with live streaming — watch Claude's text, tool uses, and structured results stream into the task detail view in real time instead of waiting on an opaque status banner
PR import — pull an existing GitHub pull request into SUSTN as a task so the auto-reply + review loop can pick up a PR you opened by hand
Full PR comment coverage — the watcher now addresses inline review comments, issue-level PR comments, and review-summary bodies (previously only inline comments were handled)
Per-repo scan toggle — disable automatic AI scans on repos that only exist to host imported PRs, or pause scanning on a repo without removing it

Improvements

Agent events persisted to SQLite so the streaming log survives app restarts and tab switches
Structured result cards in the Agent tab render review/implement JSON (pass status, issues by severity, files modified) with syntax-highlighted diffs
PR lifecycle tick processes active PRs with Promise.allSettled so multiple PRs sync and address concurrently instead of one-at-a-time
Bot-authored replies are tagged with a hidden marker so they're filtered out on the next fetch without relying on GitHub user identity
Daily budget reserves estimated tokens up front when a task starts, so concurrent starts can't over-commit the day's budget

Fixes

Resolved-thread filter is now scoped to inline comments, so issue comments sharing an ID with a resolved inline thread are no longer dropped
Imported PR repos no longer get retroactively scanned — scan_enabled defaults off for PR-import repos
Concurrency limit persists across restarts via useStartupRecovery syncing the stored value to the Rust engine at boot

PR Lifecycle & Auto-Reply

Full pull request lifecycle management with GitHub comment sync, inline review threads in the diff viewer, and automatic AI replies to PR conversations.

PR review with inline comments and conversation threads

Features

PR lifecycle management — track PRs from creation through review, addressing feedback, and merge, with real-time status in the activity timeline
GitHub PR comments in diff viewer — review comments from GitHub are displayed inline alongside the code diff for full context
Auto-reply for PR comments — SUSTN automatically responds to conversational PR comments using a unified Claude session, with a per-repo toggle to enable or disable
React error boundaries — component-level crash isolation prevents a single UI failure from taking down the entire app

Improvements

Replaced heuristic comment classifier with a unified Claude session for more accurate review vs. conversational comment handling
Compact single-card design for PR review comment threads with tighter spacing
PR lifecycle events now render in the activity timeline with clear status indicators

Fixes

Fixed null comment_id in Claude review responses causing failed comment syncs
Fixed comment classification so conversational comments are processed without requiring a formal review cycle
PR comments now always sync correctly — removed stale filter that was hiding the bot's own replies
Bypassed worker queue for engine_address_review to call Claude directly, preventing stuck addressing state

Kanban Board & Task Filtering

A new Kanban board view for visualizing tasks by status, plus powerful filtering and search to find exactly what you need.

Features

Kanban board view — visualize tasks across Pending, In Progress, Review, Done, Failed, and Dismissed columns with full drag-and-drop support
Task search — full-text search across task titles and descriptions, with Cmd/Ctrl+F keyboard shortcut
Advanced filtering — filter tasks by state, category (Feature, Tech Debt, Tests, Docs, Security, Performance, DX, Observability), and source (Manual, AI Scan, Linear)
View mode switcher — toggle between list view and Kanban board from the task toolbar
Update dialog — persistent modal when a new version is available, with 'Later' and 'Install & Restart' buttons and download progress spinner
App version display — current version (e.g. SUSTN v0.4.0) now shown in the Account section of Settings

Improvements

New task toolbar with integrated search, filter popover, and view toggle
Filter chips display dynamic counts per state for quick overview
Linear tasks now recognized as a distinct task source for filtering

Fixes

Default branch detection — repositories using master or non-standard default branches are now auto-detected when added, fixing branch creation failures
Budget calculation switched to daily mode — heavy usage on one day no longer exhausts the budget for the rest of the week
Default weekly token budget increased from 700K to 5M to match typical subscription capacity

Linear Integration

Import issues from Linear as SUSTN tasks, with full lifecycle support from sync through execution to PR link-back.

Features

Linear issue import — sync issues from any Linear team and project as SUSTN tasks, with automatic category inference from labels and effort from priority
Configurable auto-sync schedules: manual, on launch, every 6h, 12h, or daily
New Integrations tab in Settings for Linear API key management, connection testing, and per-project sync configuration
Linear identifier badges on tasks (e.g. SYN-460), clickable to open the issue in Linear
Automatic PR link-back — when SUSTN creates a PR for a Linear issue, it posts a comment on the Linear issue with the PR link

Improvements

Linear-style branch names for imported issues (e.g. sustn/syn-460-improve-accounts-table)
Linear tasks sort to the top of the task list for higher visibility
Tauri-side scan command now returns Linear metadata (identifier, URL) for imported tasks

New Diff Viewer & Inline Comments

A completely overhauled diff viewer powered by @pierre/diffs, with inline commenting for precise code review feedback.

Features

New diff renderer built on @pierre/diffs with Shiki-powered syntax highlighting, split and unified views, and word-level inline change detection
Inline comments — click the gutter to leave comments on specific diff lines, which are sent as structured feedback when requesting changes
Line selection — click and drag to highlight line ranges in the diff during review

Improvements

Smarter review loop: critical issues (bugs, security, data loss) are distinguished from non-critical suggestions — tasks soft-pass after max retries when only style nits remain
Increased max review retries from 2 to 4 for more thorough agent self-correction
Cleaner error messages — removed raw Rust Debug formatting from user-facing error strings

Fixes

Pre-flight environment checks now detect common issues (Xcode license not accepted, git not found) before starting a task, with an in-app 'Fix in Terminal' button
Environment issue listener now stays active across all routes including settings

0.1.1

Feb 24th, 2026

Preflight Fix

Fixes preflight environment checks when running as a macOS app.

Fixes

Claude Code, Git, and GitHub CLI preflight checks now resolve binaries from well-known install paths instead of relying on shell PATH, fixing false negatives when launched outside a terminal
