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

telegram-file-sender 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/send_telegram_file.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Telegram File Sender

Send any file as a document attachment to the user's Telegram chat using the Telegram Bot API.

When to Use

  • The user asks to "send me" a file, document, report, or any generated output
  • The user says "send it to me on Telegram" or "share that file with me"
  • After generating a file (PDF, DOCX, XLSX, PPTX, image, etc.) that the user wants delivered
  • The user asks to "send this to Telegram" or "attach this"
  • Post-call tasks that involve delivering files to the user

Workflow

1. Locate or Generate the File

Identify the file to send. If the file needs to be created first (e.g., a report, document, spreadsheet), generate it using the appropriate skill or tool before proceeding.

2. Send the File

Execute the bundled script to send the file via Telegram:

~/.claude/skills/telegram-file-sender/scripts/send_telegram_file.sh "<file_path>" "<optional_caption>"

Parameters:

  • file_path (required): Absolute path to the file to send
  • caption (optional): A message to display alongside the file (supports Markdown)

Environment variables (loaded automatically from .env):

  • TELEGRAM_BOT_TOKEN — The bot token
  • TELEGRAM_USER_ID — The recipient's chat ID

3. Confirm Delivery

After the script runs, confirm to the user that the file was sent. If it fails, report the error.

Constraints

  • Maximum file size: 50MB (Telegram Bot API limit)
  • For files larger than 50MB, split or compress the file first, or suggest an alternative delivery method
  • The script validates file existence and size before sending
  • Captions support Markdown formatting

Examples

Send a generated PDF report:

~/.claude/skills/telegram-file-sender/scripts/send_telegram_file.sh "/tmp/quarterly-report.pdf" "Here's your Q1 report"

Send a spreadsheet without caption:

~/.claude/skills/telegram-file-sender/scripts/send_telegram_file.sh "/path/to/budget.xlsx"

Send a presentation with formatted caption:

~/.claude/skills/telegram-file-sender/scripts/send_telegram_file.sh "/tmp/pitch-deck.pptx" "*Pitch deck* — ready for review"

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
