# 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: 03-02 complete (2 of 3 plans completed)
|
|
Status: In progress
|
|
Last activity: 2026-02-04 — Completed 03-02-PLAN.md (Suspend/Resume Implementation)
|
|
|
|
Progress: [████████████░░░] 67%
|
|
|
|
## Performance Metrics
|
|
|
|
**Velocity:**
|
|
- Total plans completed: 7
|
|
- Average duration: 16 min
|
|
- Total execution time: 2.05 hours
|
|
|
|
**By Phase:**
|
|
|
|
| Phase | Plans | Total | Avg/Plan |
|
|
|-------|-------|-------|----------|
|
|
| 1 | 3 | 27min | 9min |
|
|
| 2 | 2 | 95min | 48min |
|
|
| 3 | 2 | 6min | 3min |
|
|
|
|
**Recent Trend:**
|
|
- Last 3 plans: 02-02 (90min), 03-01 (2min), 03-02 (4min)
|
|
- Phase 3 maintaining fast execution: lightweight integration tasks
|
|
|

## 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)
|
|
- Silent suspension: No Telegram message when session auto-suspends (03-02, from CONTEXT.md)
|
|
- Switching sessions leaves previous subprocess running: It suspends on its own timer (03-02, from CONTEXT.md)
|
|
- Race prevention via per-session asyncio.Lock: Prevents concurrent suspend + resume on same session (03-02)
|
|
- Resume shows idle duration if >1 min: "Resuming session (idle for 15 min)..." (03-02)
|
|
- Orphaned PID verification via /proc/cmdline: Only kill claude processes at startup (03-02)
|
|
|
|
### 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)
|
|
|
|
**Phase 3 (Lifecycle Management) — IN PROGRESS**
|
|
- None yet
