# BTerminal — Claude Behavioral Guide
|
|
|
|
## Workflow
|
|
|
|
- v1 is a single-file Python app (`bterminal.py`). Changes are localized.
|
|
- v2 docs are in `docs/`. Architecture decisions are in `docs/task_plan.md`.
|
|
- MVP complete (Phases 1-4). Phase 5 (Agent Tree + Polish) in progress: agent tree viz, status bar, notifications, settings dialog done. Remaining: tree node click-to-focus, subtree cost display, ctx integration.
|
|
- Consult Memora (tag: `bterminal`) before making architectural changes.
|
|
|
|
## Documentation References
|
|
|
|
- Architecture & decisions: [docs/task_plan.md](../docs/task_plan.md)
|
|
- Implementation phases: [docs/phases.md](../docs/phases.md)
|
|
- Research findings: [docs/findings.md](../docs/findings.md)
|
|
- Progress log: [docs/progress.md](../docs/progress.md)
|
|
|
|
## Rules
|
|
|
|
- Do not modify v1 code (`bterminal.py`) unless explicitly asked — it is production-stable.
|
|
- v2 work goes on a feature branch (`v2-mission-control`), not master.
|
|
- All v2 architecture decisions must reference `docs/task_plan.md` Decisions Log.
|
|
- When adding new decisions, append to the Decisions Log table with date.
|
|
- Update `docs/progress.md` after each significant work session.
|
|
|
|
## Key Technical Constraints
|
|
|
|
- WebKit2GTK has no WebGL — xterm.js must use Canvas addon explicitly.
|
|
- Agent sessions use `claude` CLI with `--output-format stream-json` (not Agent SDK npm package). All output goes through the adapter layer (`src/lib/adapters/sdk-messages.ts`).
|
|
- Node.js sidecar (`sidecar/agent-runner.ts`) spawns claude subprocesses, communicates with Rust via stdio NDJSON.
|
|
- Agent dispatcher (`src/lib/agent-dispatcher.ts`) is a singleton that routes sidecar events to the agent store.
|
|
- Maximum 4 active xterm.js instances to avoid WebKit2GTK memory issues.
|
|
- Store files using Svelte 5 runes (`$state`, `$derived`) MUST have `.svelte.ts` extension (not `.ts`). Import with `.svelte` suffix. Plain `.ts` compiles but fails at runtime with "rune_outside_svelte".
|
|
- Session persistence uses rusqlite (bundled) with WAL mode. Data dir: `dirs::data_dir()/bterminal/sessions.db`.
|
|
- Layout store persists to SQLite on every addPane/removePane/setPreset change (fire-and-forget). Restores on app startup via `restoreFromDb()`.
|
|
- File watcher uses notify crate v6, watches parent directory (NonRecursive), emits `file-changed` Tauri events.
|
|
- Settings use key-value `settings` table in SQLite (session.rs). Frontend: `settings-bridge.ts` adapter, `SettingsDialog.svelte` component.
|
|
- Notifications use ephemeral toast system: `notifications.svelte.ts` store (max 5, 4s auto-dismiss), `ToastContainer.svelte` display. Agent dispatcher emits toasts on agent complete/error/crash.
|
|
- StatusBar component spans full grid width (grid-column: 1 / -1), shows pane counts, active agents, tokens, cost.
|
|
- Agent tree (AgentTree.svelte) uses SVG with recursive layout. Tree data built by `agent-tree.ts` utility from agent messages.

## Memora Tags
|
|
|
|
Project tag: `bterminal`
|
|
Common tag combinations: `bterminal,architecture`, `bterminal,research`, `bterminal,tech-stack`
|
|
|
|
## Operational Rules
|
|
|
|
All operational rules live in `.claude/rules/`. Every `.md` file in that directory is automatically loaded at session start by Claude Code with the same priority as this file.
|
