A Telegram communication guide for Antigravity, an agent setup where Telegram is the user’s message channel. It defines how to acknowledge requests, report progress, present choices, and pass work to other agents.

Use it when working through the telegram-agy connection to acknowledge incoming messages, send progress updates, edit the latest update, and report completion or blockage.

It helps keep users informed when terminal output is not visible to them. It also sets timing and reply rules so long-running work does not appear stuck.

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	$0.00071	$0.01300
Opus 5.5	$0.00028	$0.00520
Sonnet 5.5	$0.00014	$0.00260
Haiku 4.5	$0.00007	$0.00130

Security

Grade A, and why

notify-user 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.

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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

notify-user — Telegram comms playbook (Antigravity edition)

You're paired with a Telegram chat via the telegram-agy MCP plugin's bot. The user reads only what reaches the chat — anything you print to stdout or stderr never gets to them. Every inbound Telegram message MUST get a reply via the MCP tool before your turn ends, even if it's just "Done."

The loop is simple: wait_for_message → do the work → reply → wait_for_message again.

Cadence

Inbound → ack <5s. Send a short "on it" reply before starting any non-trivial work. The Telegram-paired user has no other signal that you received the message.
Long work → edit only if you're still the latest message. Use edit_message for progress updates so the user's phone doesn't buzz on every tick — but only if your previous reply is still the newest message in the chat. If a fresher message exists (a new inbound from the user, or another reply you sent in between), the edit will be missed in scrollback; send a new reply instead.
Done or blocked → new reply. A fresh reply triggers a push notification; edit_message does not.
Silence ceiling: ~60s. Beyond that the user starts assuming the bridge broke. Send a short edit or new reply (per the latest-message rule above) even mid-work if a substantive reply is still >60s away. The silence-watchdog hook will also ping the user after 120s of tool calls without a reply — that's a safety net, not something to rely on.
Default timeout_seconds=50 for wait_for_message. Antigravity kills any MCP tool call past its MCP tool timeout (default 60s), so higher timeouts drop messages arriving near the boundary. If <telegram timeout=true/> comes back, END YOUR TURN; do not re-call wait_for_message to keep polling. The server re-arms you when the next message is queued.

Hard rules

Reply via the reply MCP tool, not stdout. Plain text in your turn output is invisible to the Telegram user.
Don't auto-delegate on acknowledgements. Phrases like "you can talk now", "go ahead", "say something" mean "the channel works, please respond" — they are NOT requests to involve another agent. Reply via reply. Inter-agent handoff (via the 5dive-cli skill if installed) is appropriate only when the user explicitly asks for it ("ask scout to do this", "hand off to marketing").
Don't reply to chats you weren't messaged from. The server rejects chat_id values outside its allowlist; always source chat_id from a prior wait_for_message result.

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.
