Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

claude-telegram-bot CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

bun run typecheck  # Run TypeScript type checking
bun install        # Install dependencies

Architecture

This is a Telegram bot (~3,300 lines TypeScript) that lets you control Claude Code from your phone via text, voice, photos, and documents. Built with Bun and grammY.

Message Flow

Telegram message → Handler → Auth check → Rate limit → Claude session → Streaming response → Audit log

Key Modules

  • src/index.ts - Entry point, registers handlers, starts polling
  • src/config.ts - Environment parsing, MCP loading, safety prompts
  • src/session.ts - ClaudeSession class wrapping Agent SDK V2 with streaming, session persistence (/tmp/claude-telegram-session.json), and defense-in-depth safety checks
  • src/security.ts - RateLimiter (token bucket), path validation, command safety checks
  • src/formatting.ts - Markdown→HTML conversion for Telegram, tool status emoji formatting
  • src/utils.ts - Audit logging, voice transcription (OpenAI), typing indicators
  • src/types.ts - Shared TypeScript types

Handlers (src/handlers/)

Each message type has a dedicated async handler:

  • commands.ts - /start, /new, /stop, /status, /resume, /restart, /retry
  • text.ts - Text messages with intent filtering
  • voice.ts - Voice→text via OpenAI, then same flow as text
  • audio.ts - Audio file transcription via OpenAI (mp3, m4a, ogg, wav, etc.), also handles audio sent as documents
  • photo.ts - Image analysis with media group buffering (1s timeout for albums)
  • document.ts - PDF extraction (pdftotext CLI), text files, archives, routes audio files to audio.ts
  • video.ts - Video messages and video notes
  • callback.ts - Inline keyboard button handling for ask_user MCP
  • streaming.ts - Shared StreamingState and status callback factory

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
