What is filedropbot AGENTS.md?

Project instructions for filedropbot, a tool that moves files between a phone and a computer through the filesystem.

Use it to receive files sent from a phone and send screenshots, charts, logs, or other files back to the phone through Telegram.

It explains where incoming files appear and where to place outgoing files, so an agent can exchange files without needing an API or special integration.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00572	$0.00572
Opus 5.5	$0.00229	$0.00229
Sonnet 5.5	$0.00114	$0.00114
Haiku 4.5	$0.00057	$0.00057

Security

Grade A, and why

filedropbot AGENTS.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 2mo 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.

Agent instructions — filedropbot

This file documents the one convention an AI coding agent (Claude Code, Codex, Cursor, Aider, Gemini CLI, …) needs to know to use filedropbot. The mechanism is just the filesystem, so it works for any agent that can run shell commands — no API, SDK, or plugin required.

Receiving files from my phone

Files I send to the bot land under /root/filedropbot/data/drops/<date>/. The bot replies to me with the host path; I paste it to you. Nothing for you to do.

Sending a file to my phone

To deliver a file to me on Telegram — a screenshot, a generated chart, a log, a build artifact — copy it into the outbox:

cp /path/to/file.png /root/filedropbot/data/outbox/

Within a few seconds the bot DMs it to my phone and moves it to data/sent/<date>/. Do this whenever I ask you to "send me", "DM me", or "show me on my phone" a file.

Notes:

Limit: 50 MB per file (Telegram bot upload cap). Larger files are skipped.
Atomic writes: if you generate the file slowly, write it under a *.tmp name and mv it into the outbox when finished — the bot ignores .tmp, .part, and dotfiles until they're renamed, and otherwise waits ~2s of inactivity before sending so it never ships a half-written file.
Filenames are preserved exactly and sent as documents (no recompression).
Message caption: by default the caption equals the filename. To keep a clean filename and add context, drop a sidecar <filename>.caption.txt next to the file — its text (≤1024 chars) becomes the caption, and the sidecar is removed after sending. Example:
```
cp widget.zip /root/filedropbot/data/outbox/
printf 'ProverkaCheka widget v3.0.0' > /root/filedropbot/data/outbox/widget.zip.caption.txt
```

Wiring this into your agent's global config

So an agent knows this in every project (not just this repo), add the "Sending a file to my phone" instruction to its global standing-instructions file:

Claude Code: ~/.claude/CLAUDE.md
Codex: ~/.codex/AGENTS.md (or repo-root AGENTS.md)
Cursor: .cursor/rules/filedrop.mdc
Gemini CLI: ~/.gemini/GEMINI.md

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.
