ClaudeDo

A desktop task management app that executes tasks autonomously via Claude CLI in isolated git worktrees.

Architecture

Two-process system communicating over SignalR (127.0.0.1:47821):

• ClaudeDo.App — Avalonia desktop entry point, DI container setup
• ClaudeDo.Ui — Views, ViewModels, SignalR client (MVVM with CommunityToolkit.Mvvm)
• ClaudeDo.Data — SQLite data layer, repositories, models, GitService
• ClaudeDo.Worker — ASP.NET Core hosted service, task queue, Claude CLI runner
• ClaudeDo.Worker.Tests — xUnit integration tests with real SQLite and real git

Tech Stack

• .NET 8.0, Avalonia 12.0.0 (Fluent theme)
• SQLite (WAL mode) via Entity Framework Core (Microsoft.EntityFrameworkCore.Sqlite)
• SignalR for real-time IPC
• CommunityToolkit.Mvvm ([ObservableProperty], [RelayCommand])
• Git worktrees for task isolation

Key Paths

• DB: ~/.todo-app/todo.db
• UI config: ~/.todo-app/ui.config.json
• Worker config: ~/.todo-app/worker.config.json
• Logs: ~/.todo-app/logs/
• Worktrees: configured per worker (sibling or central strategy)

Conventions

• Repository pattern — each entity has its own async repository
• All data operations are async with CancellationToken support
• EF Core migrations manage schema (Migrations/ folder in ClaudeDo.Data)
• IDbContextFactory<ClaudeDoDbContext> used by singleton consumers (e.g. Worker)
• Entity configuration via IEntityTypeConfiguration<T> in Configuration/ folder
• Task status flow: Idle | Queued -> Running -> WaitingForReview -> Done | Failed | Cancelled. A task that spawns/has children passes through WaitingForChildren first, then surfaces for review once every child is terminal — this is the single parent model for both planning and improvement parents (planning/improvement children themselves go straight to Done, only the parent is reviewed). From review you can approve, reject-rerun (Queued, resumes the session with feedback), reject-park (Idle), or cancel. Approve is the single review+merge action: a childless task merges its own worktree then Done (conflicts keep it in WaitingForReview); a task with children drives the unit merge (parent worktree if any + each Done child in order, with conflict continue/abort). Tasks with no active worktree (sandbox run) approve straight to Done.
• Worktree state flow: Active -> Merged | Discarded | Kept
• The queue picker claims tasks by Status=Queued (with BlockedByTaskId IS NULL); the legacy tag system was removed
• Interfaces live in an Interfaces/ subfolder beside their consumers (namespace unchanged)
• Small single-consumer helper types live in their consumer's file, not standalone files
• Commit messages use conventional format: {commitType}(slug): title
• Views use compiled bindings (x:DataType)
• ViewModels use [ObservableProperty] and [RelayCommand] source generators

Working style (autonomous)

For any non-trivial feature, bug, or change, run this loop without hand-holding:

1. Brainstorm first (superpowers:brainstorming) — ask clarifying questions one at a time, propose 2–3 options with a recommendation, present a short design, get approval before building.
2. Write it down — a spec in docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md and a step-by-step plan in docs/superpowers/plans/ (superpowers:writing-plans). Commit the docs.
3. Implement on main with superpowers:subagent-driven-development — one subagent per task, TDD, build + test, commit per task with Conventional Commits. Once the plan is approved, do NOT pause for re-approval between tasks; only stop for genuine decisions or blockers.
4. Trust but verify — read each subagent's diff and run the build/tests yourself before marking a task done.
5. Bugs → superpowers:systematic-debugging (find the root cause before any fix).
6. Never claim UI works without running it — explicitly flag visual-verification gaps for the user to check.

Commit freely (per task + the spec/plan docs). Never push without asking.

Building & Testing

dotnet build ClaudeDo.slnx requires .NET 9; on .NET 8 build individual projects with -c Release (a running Worker locks the Debug output).

dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release      # pulls in Ui + Data
dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release
dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release   # also: Data.Tests, Ui.Tests, Localization.Tests, Installer.Tests, Releases.Tests

Gotchas

• Subagents: use the sonnet model; stage files explicitly by path — never git add -A (parallel sessions often leave unrelated WIP in the tree).
• Icons: PathIcon fills its geometry. Line-art/stroke icons must be authored as filled geometry, or rendered with a stroked Path — otherwise they render invisible.
• Localization: locales/en.json and locales/de.json keys must stay in parity (Localization.Tests enforces it).
• Test fakes: changing IWorkerClient / WorkerHub / ViewModel constructors breaks hand-rolled fakes in both test projects — update them.
