# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-02-04)

**Core value:** Frictionless conversation with Claude Code from anywhere via Telegram — no SSH, no manual inbox checking, just message and get a response.
**Current focus:** Phase 1 (Session & Process Foundation)

## Current Position

Phase: 1 of 4 (Session & Process Foundation)
Plan: 01-03 complete (3 of 3 plans completed)
Status: Phase 1 complete
Last activity: 2026-02-04 — Completed 01-03-PLAN.md (Bot command integration)

Progress: [███░░░░░░░░░░░░] 25%

## Performance Metrics

**Velocity:**
- Total plans completed: 3
- Average duration: 10 min
- Total execution time: 0.50 hours

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 1     | 3     | 27min | 9min     |

**Recent Trend:**
- Last 3 plans: 01-01 (3min), 01-02 (9min), 01-03 (15min)
- Trend: Increasing complexity (more orchestrator fixes)

*Updated after each plan completion*

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- Claude Code CLI over raw API: Gets full tool access, --resume support, and all Claude Code features for free
- Haiku polling + Opus conversation: Avoids burning expensive Opus tokens on idle monitoring (deferred to v2)
- Path-based sessions: Leverages Claude Code's native session-per-directory behavior, files naturally scoped
- Extend existing bot: Reuse proven Telegram integration rather than building from scratch
- Sessions created as 'idle', activated explicitly: Creating doesn't mean in use, switch required (01-01)
- Metadata read from disk on demand: No caching to avoid stale state (01-01)
- Asyncio.gather for concurrent stream reading: Prevents pipe deadlock (01-02)
- Fresh process per turn: Spawn new `claude -p` invocation for Phase 1 simplicity (01-02)
- Callback architecture: Decouple subprocess from session management via on_output/on_error/on_complete/on_status (01-02)
- Sibling imports over package imports: Avoids shadowing pip telegram package (01-03)
- Archive sessions with tar+pigz: Compression + cleanup to sessions_archive/ (01-03)

### Pending Todos

None yet.

### Blockers/Concerns

**Phase 1 (Session & Process Foundation) — COMPLETE**
- ~~Claude Code CLI --resume behavior with pipes vs PTY unknown~~ — RESOLVED: Research confirms pipes + stream-json is correct approach
- ~~Output format for tool calls not documented~~ — RESOLVED: stream-json format documented and implemented

**Phase 2 (Persistent Processes) — BLOCKER:**
- **Non-persistent process model:** Current implementation spawns fresh `claude -p` per turn (~1s overhead each)
  - Design goal was persistent processes that suspend when switching sessions
  - This gap affects response latency and user experience
  - Must be addressed before Phase 3 integration
  - Requires refactoring ClaudeSubprocess to lifecycle-manage process instances

**Phase 3 (Telegram Integration):**
- Message batching strategy needs validation against actual Claude output patterns
- Optimal chunk split points require experimentation
- Streaming responses / typing indicators needed for UX during long API waits

## Session Continuity

Last session: 2026-02-04T18:00:00Z
Stopped at: Completed 01-03-PLAN.md (Bot command integration)
Resume file: None
Next: Phase 2 ready (persistent process model needed)
