# 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 2 complete, ready for Phase 3

## Current Position

Phase: 2 of 4 (Telegram Integration) — COMPLETE
Plan: 02-02 complete (2 of 2 plans completed)
Status: Complete
Last activity: 2026-02-04 — Completed 02-02-PLAN.md (Bot integration with batching, file handling, systemd service)

Progress: [██████████░░░░░] 50%

## Performance Metrics

**Velocity:**
- Total plans completed: 5
- Average duration: 23 min
- Total execution time: 1.95 hours

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 1     | 3     | 27min | 9min     |
| 2     | 2     | 95min | 48min    |

**Recent Trend:**
- Last 3 plans: 01-03 (15min), 02-01 (5min), 02-02 (90min)
- 02-02 included interactive debugging and human verification

*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)
- Persistent subprocess instead of fresh per turn: Eliminates ~1s spawn overhead, maintains context (02-01)
- Split messages at 4000 chars (not 4096): Leaves room for MarkdownV2 escape expansion (02-01)
- Never split inside code blocks: Track in_code_block state, only split when safe (02-01)
- Dynamic typing event lookup: Callbacks reference typing_tasks dict by session name, not captured event (02-02)
- --append-system-prompt instead of --system-prompt: Preserves Claude Code model identity (02-02)
- --dangerously-skip-permissions: Full tool access in non-interactive subprocess (02-02)
- Full model ID in persona: Use claude-sonnet-4-5-20250929 instead of alias (02-02)
- Stream-json NDJSON format: {type: user, message: {role: user, content: text}} (02-02)

### Pending Todos

None yet.

### Blockers/Concerns

**Phase 1 (Session & Process Foundation) — COMPLETE**
- ~~Claude Code CLI --resume behavior with pipes vs PTY unknown~~ — RESOLVED
- ~~Output format for tool calls not documented~~ — RESOLVED

**Phase 2 (Telegram Integration) — COMPLETE**
- ~~Non-persistent process model (spawned fresh per turn)~~ — RESOLVED (02-01)
- ~~Message batching strategy needs validation~~ — RESOLVED: Works with 2s debounce (02-02)
- ~~File upload flow needs end-to-end testing~~ — RESOLVED: User-verified (02-02)
- ~~Typing indicator not visible despite API success~~ — RESOLVED: Stale task cleanup + dynamic event lookup (02-02)
- ~~Model identifies as wrong version~~ — RESOLVED: --append-system-prompt preserves CLI defaults (02-02)
