Alan Wizemann 18278a3357 Initial release: Scarf — macOS GUI for the Hermes AI agent

Native SwiftUI app providing full visibility into the Hermes AI agent:
- Dashboard with system health, token usage, and cost tracking
- Sessions browser with conversation detail and FTS5 search
- Activity feed with tool call inspector (read/edit/execute/fetch/browser)
- Embedded terminal chat via SwiftTerm with full ANSI/Rich rendering
- Memory viewer/editor with live file-watching refresh
- Skills browser by category with file content viewer
- Cron job viewer with output display
- Real-time log tailing with level filtering
- Settings display with raw config and Finder path links
- Menu bar status icon with quick actions

Architecture: MVVM-Feature, zero dependencies beyond SwiftTerm,
read-only SQLite access, Swift 6 strict concurrency.

Scarf — macOS GUI for the Hermes AI Agent

Project Structure

scarf/scarf/           Xcode project root (PBXFileSystemSynchronizedRootGroup — auto-discovers files)
  scarf/               Main app target source
    Core/Services/     HermesDataService, HermesFileService, HermesLogService, ACPClient, HermesFileWatcher
    Core/Models/       Plain structs: HermesSession, HermesMessage, HermesConfig, etc.
    Features/          MVVM-F feature modules (Dashboard, Sessions, Activity, Chat, Memory, Skills, Cron, Logs, Settings)
    Navigation/        AppCoordinator, SidebarView
  docs/                PRD, Architecture, Discovery notes
  standards/           Copied development standards (read-only reference)

Architecture Rules

MVVM-F: Features never import sibling features. Cross-feature goes through services.
AppCoordinator: Single @Observable coordinator for all navigation state, injected via .environment().
No external dependencies: System SQLite3, Foundation JSON, AttributedString markdown.
Read-only DB access: Never write to ~/.hermes/state.db. Only write to memory files and cron jobs.
Sandbox disabled: App reads ~/.hermes/ directly.
Swift 6 concurrency: @MainActor default. Services use nonisolated + async/await.

Key Paths

Hermes home: ~/.hermes/
SQLite DB: ~/.hermes/state.db (WAL mode, read-only)
Config: ~/.hermes/config.yaml
Memory: ~/.hermes/memories/MEMORY.md, ~/.hermes/memories/USER.md
Sessions: ~/.hermes/sessions/session_*.json
Cron: ~/.hermes/cron/jobs.json
Logs: ~/.hermes/logs/errors.log, ~/.hermes/logs/gateway.log
ACP: hermes acp subprocess (stdio JSON-RPC)
