# 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: 3 of 4 (Lifecycle Management) — IN PROGRESS
Plan: 03-01 complete (1 of 3 plans completed)
Status: In progress
Last activity: 2026-02-04 — Completed 03-01-PLAN.md (Idle timer foundation)
Progress: [████████████░░░] 60%
## Performance Metrics
**Velocity:**
- Total plans completed: 6
- Average duration: 18 min
- Total execution time: 1.98 hours
**By Phase:**
| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 1 | 3 | 27min | 9min |
| 2 | 2 | 95min | 48min |
| 3 | 1 | 2min | 2min |
**Recent Trend:**
- Last 3 plans: 02-01 (5min), 02-02 (90min), 03-01 (2min)
- 03-01: Fast foundation module creation
*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)
- Default 600s (10 min) idle timeout per session: Balances responsiveness with resource conservation (03-01)
- Timer reset via task cancellation: Cancel existing task, create new background sleep task (03-01)
- PID property returns live process ID only: None if terminated to prevent stale references (03-01)
### 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)
**Phase 3 (Lifecycle Management) — IN PROGRESS**
- None yet
